1. Introduction 

In 1992, the Childhood Immunization Initiative (CII) (CDC 1994) was established to 1) improve the 

delivery of vaccines to children; 2) reduce the cost of childhood vaccines; 3) enhance awareness, 

partnerships, and community participation; 4) improve vaccinations and their use; and 5) monitor 

vaccination coverage and occurrences of disease. Subsequently, the Healthy People 2020 objectives 

established a target for adolescents aged 13–15 years of 80% coverage with ≥ 1 Tdap, ≥ 1 MenACWY, 

and ≥ 3 HPV doses in females and males, and 90% coverage for ≥ 2 varicella vaccine doses, and the 

Healthy People 2030 objectives for vaccination coverage aim to increase the proportion of adolescents 

aged 13 through 15 years who have received the recommended number of doses of HPV vaccine (≥2 or 

≥3 doses) among females and males combined to 80% by 2030. To fulfill the CII mandate of monitoring 

vaccination coverage and marking progress toward achieving those objectives, the National Immunization 

Survey (NIS) Family of Surveys with an adolescent component called the NIS-Teen was implemented by 

the National Center for Immunization and Respiratory Diseases (NCIRD) and the National Center for 

Health Statistics (NCHS) of the Centers for Disease Control and Prevention (CDC) in 2006

(http://www.cdc.gov/vaccines/imz-managers/nis/about.html). 

The target population for the NIS-Teen is non-institutionalized adolescents aged 13–17 years living in 

United States households at the time of the interview. The official coverage estimates reported from the 

NIS-Teen are proportions of adolescents up-to-date with respect to the recommended numbers of doses of 

all routinely recommended vaccines for adolescents and selected catch-up vaccines (Wodi et al. 2021). 

These vaccines and their recommended numbers of doses are: 

• Tetanus, diphtheria, and acellular pertussis vaccine (Tdap) – 1 dose;

• Quadrivalent meningococcal vaccine (MenACWY) – 2 doses; 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 2 

• Human papillomavirus vaccine (HPV) – 2 or 3 doses, depending on age at first dose1; 

• Measles, mumps, and rubella vaccine (MMR) – 2 doses;

• Hepatitis B vaccine (Hep B) – 3 doses;

• Varicella zoster (chicken pox) vaccine – 2 doses among adolescents with no varicella disease 

history; 

• Hepatitis A vaccine (Hep A) – 2 doses; and

• Seasonal influenza vaccine – 1 dose annually. 

The NIS-Teen is conducted as an add-on to the National Immunization Survey - Child (NIS-Child), 

which seeks to estimate vaccination coverage rates among 19–35 month-old children. The NIS-Child uses 

a random digit dialing (RDD) telephone survey to identify households containing children aged 19–35 

months and interviews the adult who is most knowledgeable about the child’s vaccinations. If such a 

household is identified and the NIS-Child interview is completed, the household is then screened for the 

presence of 13–17 year-old adolescents. Households that do not contain a 19–35 month old child are not

administered the NIS-Child interview but are immediately screened for the presence of a 13–17 year-old 

adolescent. If a household containing one or more adolescents aged 13–17 years is identified, a 13–17 

year-old adolescent is randomly chosen, and the adult who is most knowledgeable about the teen's 

vaccinations is interviewed. With consent of the teen's parent or guardian, the NIS-Teen also contacts (by 

mail) the teen's vaccination provider(s) to request information on vaccinations from the teen's medical 

records. NIS-Teen sampling, data collection, and weighting operations are conducted by NORC at the 

University of Chicago.

1 The 2-dose HPV vaccination schedule was approved in October 2016 for adolescents who received their first dose 

before age 15 (Meites, Kempe, and Markowitz, 2016). Therefore, changes in vaccination due to the new 

recommendation would be reflected in the 2021 NIS-Teen data only for adolescents receiving HPV vaccinations 

after that time (see Walker et al., 2018).
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 3 

Samples of telephone numbers are drawn independently, for each calendar quarter, within selected 

geographical areas. For the 2021 NIS-Teen, there are 59 geographic strata for which vaccination coverage 

levels can be estimated, including 5 local areas; the remaining 53 are either an entire state, the District of 

Columbia, a U.S. territory (the U.S. Virgin Islands, Guam, or Puerto Rico), or a “rest of state” area. This 

design makes it possible to produce annual estimates of vaccination coverage levels within each of the 59

estimation areas with a specified degree of precision (a coefficient of variation of approximately 6.5%). 

Further, by using the same data collection methodology and survey instruments in all estimation areas, the 

NIS-Teen produces comparable vaccination coverage levels among estimation areas and over time.

When the NIS-Teen was first conducted in Quarter 4 of 2006 and Quarter 4 of 2007, the survey was 

designed to produce estimates at the national level only. Starting in 2008, the NIS-Teen was expanded to 

produce estimates in 56 areas, including the 50 states, District of Columbia, and 5 local areas that receive 

federal Section 317 immunization grants (Bexar County, TX; City of Chicago, IL; City of Houston, TX; 

New York City, NY; Philadelphia County, PA). These areas are called estimation areas. In 2021, the 

NIS-Teen included the U.S. Virgin Islands, Guam, and Puerto Rico as additional estimation areas.

As noted throughout this report, some procedures differed for territories when compared to the rest of the 

United States, including the creation of separate survey weight variables for analyses that are to include 

territories. 

Data for the U.S. Virgin Islands and Guam are not included in the 2021 public-use data file to protect 

respondent confidentiality, as the sampling fractions were large in these small-population area. Interested 

researchers can access data for the U.S. Virgin Islands and Guam by submitting a proposal and working 

through the Research Data Center. The link and guidelines for developing a proposal are located at 

https://www.cdc.gov/rdc. 

For the 2021 NIS-Teen, household interviews began on January 7, 2021 and ended on February 3, 

2022. Provider data collection extended from January 2021 through April 2022. A total sample, 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 4 

including the territory samples, of approximately 12.1 million telephone numbers yielded household 

interviews for 46,379 teens, 18,822 of whom had adequate provider data (provider-reported 

vaccination data adequate to determine whether the teen was up-to-date with respect to the 

recommended vaccination schedule). The 2021 NIS-Teen public-use data file (which includes data 

from Puerto Rico but does not include data for the U.S. Virgin Islands and Guam) contains data for 

45,036 teens with completed household interviews, and more extensive data (e.g., provider-reported 

vaccination histories and facility data) for 18,352 teens with adequate provider data (including 104

unvaccinated teens). Data were collected in the U.S. Virgin Islands and Guam in 2021, although 

adolescents in these areas are not included on the public-use data file in order to protect their 

confidentiality. 

NIS-Teen vaccination coverage estimates are based on provider-reported vaccination histories from 

adolescents with adequate provider data (APD). In 2014, the household questionnaire was shortened to 

reduce the length of the household interview, decrease respondent burden, and potentially improve survey 

response rates. Questions that were previously used to define APD were no longer available, thus 

necessitating a modification to the APD definition used by the NIS-Teen. See the Data User’s Guide for 

the 2014 NIS-Teen Public-Use Data File for a description of this change. NIS-Teen estimates for 2021

will be directly comparable to NIS-Teen estimates published since 2014, but not to estimates published

prior to 2014. 

The weights included in this public-use data file allow data analysts the capability of conducting several 

different types of analysis, depending on interests and aims. One can choose to analyze all teens with 

completed household interviews or only the subset of teens for whom the provider-reported data are 

adequate. CDC publishes estimates of vaccination coverage based on provider-reported vaccination 

histories using the subset of teens for whom the provider-reported data are adequate. Parental reported 

vaccination status is subject to recall error (Dorell et al. 2011, Ojha et al. 2013). Also, one can choose to 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 5 

include or exclude teens who reside in territories in the analysis. Previous NIS-Teen public-use files have 

provided analysts with these capabilities as well. Section 6 of this user’s guide provides information about 

the creation of the weight variables included in the 2021 NIS-Teen public-use data file, and Section 8 

provides guidance for their use. 

Vaccination coverage estimates for 2021 are available on the TeenVaxView website,

2. Sample Design 

The NIS-Teen uses two phases of data collection to obtain vaccination information for a large national 

probability sample of teens: (1) a RDD telephone survey designed to identify households with adolescents

13 to 17 years of age, followed by (2) the Provider Record Check, a mailed survey to teens’ vaccination

providers. This section summarizes these two phases of data collection. Other descriptions of the sample 

design are given by Ezzati-Rice et al. (1995), Zell et al. (2000), Smith et al. (2001a, 2005), Jain et al. 

(2009), and Wolter et al. (2017a). 

2.1. The NIS-Teen RDD Telephone Survey 

The NIS-Teen RDD telephone survey phase uses independent, quarterly samples of telephone numbers.

Sampling frames were provided by Marketing Systems Group (MSG). Cellular phone numbers were 

sampled within estimation areas in each quarter of 2021. Table E.1 (in Appendix E) lists the estimation

areas for the 2021 NIS-Teen by state or territory and shows the estimated number of teens living in each 

state or territory and estimation area in 2021.

Because the NIS-Teen is an add-on survey to the NIS-Child, the NIS-Teen uses the same sampling frame 

and sampling methodology as the NIS-Child. In 2021, the NIS-Teen utilized a single-frame cellular phone

sampling design, with telephone numbers sampled only from a sampling frame of cellular phone 

numbers. Prior to 2011, the NIS-Teen was based on a landline telephone sample. A cellular phone sample

was added to the survey in 2011 in order to address the rapid rise of cellular phone-only households. As 

cellular phone penetration has increased, fewer and fewer households, especially households with 

children, have relied only on a landline telephone. Because the proportion of households with children 

that are reachable only by landline telephone is now very small – only 0.4% in 2021 (Blumberg and Luke 

2022) – the landline sample was dropped beginning in 2018, and the NIS-Teen now uses only a cellular 

phone sample. A discussion of this change and its impact is given by Nguyen et al. (2019).
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 7 

The target sample size of completed telephone interviews in each estimation area is designed to achieve 

an approximately equal coefficient of variation of 6.5% for an estimator of vaccination coverage derived 

from provider-reported vaccination histories, given a true coverage parameter of 50%. Cellular phone 

sample sizes were chosen to meet the target coefficient of variation of 6.5%.

Since 2019, the NIS sample design has included a modification to increase the efficiency of data 

collection. Immunization Information Systems (IIS) are state or local confidential, computerized, 

population-based data systems that collect and consolidate vaccination doses administered by 

participating vaccination providers to persons residing in a given geopolitical area. In participating 

geographic estimation areas, a two-phase RDD sample of cellular phone numbers is selected, with the 

second-phase sample stratified by the status of the telephone number in the corresponding IIS: 

• Stratum 1: Phone number associated with a 19-35 month old child in the IIS

• Stratum 2: Phone number associated with a 13-17 year old adolescent in the IIS (but not with a 

19-35 month old child in the IIS)

• Stratum 3: Phone number associated with a 6-18 month or 3-12 year old child in the IIS (but not 

with a 19-35 month old child or 13-17 year old adolescent in the IIS)

• Stratum 4: Phone number not associated with a 6 month to 17 year old child in the IIS

In the second phase of sampling, phone numbers falling into Strata 1, 2, and 3 were oversampled. The 

method was designed to maximize the effective sample sizes for the NIS family of surveys, given a fixed 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 8 

cost for data collection, within each of the participating geographic estimation areas. For the 2021 

sample, there were 27 participating areas.2

 

In 2021, including the U.S. territory samples, 40.6% of teens with a completed household interview 

were determined to have adequate provider data. Excluding territories, this proportion was 41.2%. 

The percentage of teens with adequate provider data in 2021 varies among the non-territory 

estimation areas (from 34.1% in California to 55.9% in Vermont). Among the U.S. territories, the 

percentages were 34.2% in the U.S. Virgin Islands, 35.9% in Guam, and 26.3% in Puerto Rico. The 

phrase “adequate provider data” means that sufficient vaccination history information was obtained from 

the provider(s) to determine whether the teen is up-to-date with respect to the recommended vaccination 

schedule. In 2014, the definition of adequate provider data was expanded to include all adolescents with 

provider-reported vaccination data; see the Data User’s Guide for the 2014 NIS-Teen Public-Use Data 

File for a description of this change. In 2021, the NIS-Teen began collecting data on COVID-19 

vaccination, and the definition of adequate provider data was further revised to exclude adolescents 

for whom only COVID-19 vaccinations were reported; this change was made to maintain 

consistency in the definition between 2021 and prior years. Unvaccinated teens are also considered to 

have adequate provider data. These are teens for whom either (1) the respondent reported during the 

household interview that the teen had received no vaccinations and has no providers, or (2) the respondent 

reported during the household interview that the adolescent had received no vaccinations but has one or 

more providers, and those providers all reported administering no vaccinations. The number of 

unvaccinated teens in the sample is small (109 in 2021, including the U.S. territory samples).

2 The participating geographic areas in 2021 were Alaska, Arkansas, Connecticut, Idaho, Iowa, Kansas, Louisiana, 

Maryland, Michigan, Mississippi, Missouri, Nebraska, Nevada, New Mexico, New York – City of New York, North 

Carolina, North Dakota, Ohio, Rhode Island, South Dakota, Tennessee, Utah, Vermont, Washington, Wyoming, the 

U.S. Virgin Islands, and Puerto Rico. Not all of these areas utilized the IIS-NIS integration design in every quarter 

of 2021. Arkansas and Iowa used the integration design in quarters 3 and 4, and the U.S.Virgin Islands used it only 

in quarter 4. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 9 

The design and implementation of the NIS-Teen cellular phone sample involve three procedures. First, 

statistical models predict the number of sample cellular phone numbers needed in each estimation area to 

meet the target precision requirements, and, from among the entire NIS-Child sample of telephone 

numbers, this number of telephone numbers are “flagged” to be part of the NIS-Teen sample. Second, the 

sample for an estimation area is divided into random sub-samples called replicates. By releasing 

replicates as needed, it is possible to spread the interviews for each sampling area evenly across the entire 

calendar quarter. Third, an automated procedure eliminates numbers on the NIS do-not-call list from the 

sample before the interviewers dial them.

In 2014 and 2015, an automated process was implemented to remove cellular phone numbers flagged as 

having no recent activity and that were therefore very likely to be non-working cellular phone numbers. 

In 2016, a different automated process found to be more efficient in removing non-working cellular phone 

numbers was used. Following a July 2016 Federal Communications Commission (FCC) declaratory 

ruling (FCC 16-72, CG Docket No. 02-278) stating that the federal government and contractors working 

on behalf of the federal government are not subject to the restrictions on cellular phone dialing in the 

Telephone Consumer Protection Act of 1991 (TCPA, 47 U.S.C. 227), the NIS transitioned from manual 

dialing of cellular phones to auto-dialing cellular phones in November 2016. After this transition, the 

automated process to remove non-working cellular phone numbers was no longer cost effective, and 

beginning in 2017 this process was no longer used in the cellular phone sample.

2.2. The NIS-Teen Provider Record Check

At the end of the household interview, consent to contact the teen’s vaccination provider(s) is requested 

from the parent/guardian. When oral consent is obtained, each provider is mailed an immunization history 

questionnaire (IHQ). This mail survey portion of the NIS-Teen is the Provider Record Check. 

The instructions ask vaccination providers to mail or fax the immunization history questionnaire back 

upon completion. Two weeks after the initial mailing, a telephone call is made to providers who have still 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 10

not responded, to remind and encourage them to complete the form and either mail or fax the information 

back. In some instances, provider-reported vaccination histories are completed over the telephone. The 

data from the questionnaires are edited, entered, cleaned, and merged with the household information 

from the RDD survey to produce a teen-level record.

2.3. Summary of Data Collection

Table 1 presents selected operational results of NIS-Teen data collection for calendar year 2021 for the 

NIS-Teen sample. To facilitate comparisons with prior NIS-Teen surveys, the numbers in Table 1 and 

discussed in this section exclude the U.S. territory samples. Adolescents aged 13–17 years during 2021

data collection were born between January 2003 and January 2009. 

The total cellular phone RDD sample (in replicates that were released for use) consisted of 

11,052,632 telephone numbers. Of these, 31,096 were eliminated before release to the telephone 

centers as numbers on the NIS do-not-call list, and the remaining 11,021,536 were sent to the 

telephone centers to be dialed. A total of 932,713 active personal cellular phone numbers (APCNs)

were identified as shown in Row F. Among the identified APCNs, 724,820 (77.7%) were successfully 

screened. Of these, 63,723 (8.8%) were deemed eligible for the NIS-Teen interview. Respondents

were eligible if the cellular phone belonged to an adult living in a household with at least one ageeligible teen. Among the identified eligible households, 43,608 (68.4%) completed the household 

interview.

A standard approach for measuring response rates in telephone surveys has been defined by the Council 

of American Survey Research Organizations (CASRO 1982). The CASRO response rate is equivalent to 

“RR3” of AAPOR Standard Definitions (AAPOR 2016). In 2021, the CASRO response rate (Row J) 

was 21.0%. The NIS-Teen CASRO response rate equals the product of the resolution rate (39.6%, 

Row E), the screening completion rate (77.7%, Row G), and the interview completion rate among 

eligible households (68.4%, Row I). The resolution rate is the percentage of the total telephone numbers 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 11

selected that are classifiable as non-working, non-residential, or residential. The screening completion 

rate is the percentage of known households that are successfully screened for the presence of age-eligible 

teens. The interview completion rate is the percentage of households with one or more age-eligible teens 

that complete the household interview.

Row K of Table 1 shows that household interviews were completed for 43,707 age-eligible teens. 

This figure is smaller than that in Row I because some completed interviews were removed when 

edits to the teen’s date of birth rendered the teen ineligible. Rows L through O give results for the 

Provider Record Check phase. Specifically, Row L gives the rate of obtaining oral consent from 

household respondents to contact their teen's vaccination providers – 51.6% in 2021. The number of 

immunization history questionnaires mailed to vaccination providers exceeds the number of completed 

interviews for teens with consent because some teens have more than one vaccination provider. Of the 

questionnaires mailed to providers of teens, 29,649 (87.6%, Row N) were returned. Among the 

teens with completed household interviews, 18,002 (41.2%, Row O) had adequate vaccination 

histories based on provider reporting (17,899) or were determined to be unvaccinated (103). The 

other 58.8% of teens lacked adequate provider data for a variety of reasons, such as the parent or 

guardian did not give consent to contact the teen's provider(s), the provider(s) did not respond, or 

the provider(s) responded but did not report any vaccinations for the teen despite the parent or 

guardian indicating that the teen has received vaccinations. 

In 2021, data from the Health Insurance Module (HIM) were collected. Among the 43,707 teens with 

completed household interviews, 23,728 (54.3%, Row P) completed the HIM. 

For each estimation area and each state or territory, Table E.1 (see Appendix E) shows the number of 

teens with completed household interviews and the number of teens with adequate provider data.

6 The response rate is the number of households with a completed household interview divided by the estimated number of 

eligible households in the sample. The number of eligible households was estimated using the CASRO assumptions; these 

assumptions are that the rate of households among the unresolved telephone numbers is the same as the observed rate of 

households among the resolved telephone numbers, and the rate of eligible households among unscreened households is the 

same as the observed rate of eligible households among screened households. Under these assumptions, the CASRO 

response rate is equal to the product of the resolution rate, the screener completion rate, and the interview completion rate. 7 Rows K-P reflect the removal of teens with an ineligible best date of birth.

2.4. Informed Consent, Security, and Confidentiality of Information

The introduction to the telephone survey and oral consent assure the respondent of the confidentiality of 

his/her responses and the voluntary nature of the survey. Informed consent is obtained from the person in 

the household most knowledgeable about the eligible teen’s vaccination history (generally the parent or 

guardian of the teen). Informed consent to contact the teen’s vaccination provider(s) is obtained at the end 

of the interview.

Information in the NIS-Teen is collected and processed under high security. To ensure privacy of the 

respondents and confidentiality of sensitive information, standards have been established for release of 

data from this survey. All CDC staff and contractor staff involved with the NIS-Teen sign confidentiality 

agreements and follow instructions to prevent disclosure. 

All information in the NIS-Teen is collected under strict confidentiality and can be used only for research 

[Section 308(d) of the Public Health Service Act, 42 U.S. Code 242m(d), the Privacy Act of 1974 (5 U.S. 

Code 552a)]. Prior to public release, the contents of the public-use data file go through extensive review 

by the NCIRD Disclosure Review Board to protect participant privacy as well as data confidentiality.

3. Content of NIS-Teen Questionnaires 

This section describes the questionnaires used in the 2021 NIS-Teen telephone interview of households 

and in the NIS-Teen Provider Record Check. 

3.1. Content of the Household Questionnaire 

The computer-assisted telephone interview (CATI) questionnaire used in the RDD phase of NIS-Teen

data collection consists of two parts: a screener to identify households with adolescents aged 13 through 

17 years and an interview portion. The questionnaire is modeled on the Immunization Supplement to the 

National Health Interview Survey (NHIS) (NCHS 1999). The NIS-Teen CATI questionnaire has been 

translated into Spanish, and LanguageLine Solutions® (formerly part of AT&T) is used for real-time 

translation into many other languages (Wall et al. 1995). Table 2 summarizes the content of each section 

of the NIS-Teen household interview. The CATI questionnaire is available at

http://www.cdc.gov/vaccines/imz-managers/nis/datasets-teen.html.

The household is first screened for the presence of children aged 19 through 35 months. If the household 

contains such a child, the NIS-Child interview is conducted before the household is screened for the NISTeen survey; if the household does not contain such a child, the household immediately proceeds to the 

NIS-Teen screener.

In the NIS-Teen screener, the purpose of the survey is explained to the respondent, and the ages of all the 

children in the household are obtained. If the household contains one or more adolescents aged 13

through 17 years, a 13 through 17 year-old adolescent is randomly chosen to be the subject of the 

interview, this teen’s date of birth is collected, and the respondent is asked whether he/she is the most 

knowledgeable person for this teen’s vaccination history. If the respondent indicates that another person 

in the household is more knowledgeable, the interviewer asks to speak to him/her at that time. If that 

person is unavailable to be interviewed, the name of the most knowledgeable person is recorded, and a 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 15

callback is scheduled for a later date. Prior to screening for age-eligibility the household is screened to 

ensure that the cellular phone is used by an adult (i.e., to ensure it is not a minor-only cellular phone).

Section E Health Insurance Module (HIM)

The standard NIS-Teen questionnaire formerly included Section A following the NIS-Teen Screener. 

After asking whether the respondent has a shot card of the teen’s vaccination history, he/she was formerly 

asked whether the shot card was easily accessible. If so, the interview proceeded with Section A (which 

asked respondents with shot cards about the shots on the card), followed by Section C; if not, it proceeded 

with Section B followed by Section C. Beginning in Q1/2014, Section A was eliminated from the regular 

household questionnaire and all respondents were administered Section B. Section B was also shortened. 

The remaining Section B questions are a limited set of questions regarding flu, Td/Tdap, meningococcal,

and HPV vaccinations; questions about measles, varicella, hepatitis A, and hepatitis B vaccines were 

removed. In 2015 and 2016, Section A was reinstated for Guam respondents, but was discontinued for all 

respondents beginning in 2017. 

Section C collects information about the health of the selected teen, including recent doctor visits and 

history of chicken pox disease, asthma, and other health conditions. Section C obtains information that 

includes the relationship of respondent to the teen, race and Hispanic origin of the teen, household 

income, educational attainment of the mother, and other information on the socioeconomic characteristics 

of the household and the teen. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 16

In the Provider Section (Section D) of the NIS-Teen household interview, identifying information (such 

as name, address, and telephone number) for the teen’s vaccination provider(s) is requested, as well as the 

full names of the teen and the respondent, so that NIS-Teen personnel can contact the provider(s) and 

identify the teen whose vaccination information the NIS-Teen is requesting. After this information is 

obtained, consent to contact the teen’s vaccination provider(s) is requested. When oral consent and 

sufficient identifying information are obtained, the immunization history questionnaire is mailed to the 

teen’s vaccination provider(s). 

A Health Insurance Module (HIM) (Section E) is administered upon completion of the Provider Section

to collect data regarding the types of medical insurance coverage the teen has had since age 11 years. If a 

respondent provided consent to contact medical providers and completed the Provider Section, he/she 

flowed directly into the HIM. If, however, consent or any other critical provider question was refused, the 

call was terminated; only upon callback on which consent was granted or a second refusal given within 

the Provider Section was the respondent asked the HIM. 

3.2. Content of the Immunization History Questionnaire (IHQ)

The IHQ mailed to the vaccination providers is designed to be simple and brief, to minimize provider

burden and encourage survey participation. The structure and content of this form were initially derived 

from the National Immunization Provider Record Check Study (NHIS/NIPRCS), which collected and 

reconciled vaccination data from the providers of respondents to the Immunization Supplement to the 

National Health Interview Survey. The IHQ consists of two double-sided pages. Page 1 includes space for 

the label that gives the teen’s name, date of birth, and sex. The remainder of page 1 contains questions 

about the facility and vaccination provider. Page 2 gives instructions for filling out the shot grid, which 

appears on page 3. Page 4 thanks the vaccination provider for providing the information, and lists 

websites and telephone numbers that can be used to obtain more information about the NIS-Teen and the

Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 18

4. Data Preparation and Processing Procedures 

The household and provider data collection in the NIS-Teen incorporate extensive data preparation and 

processing procedures. During the household interview, the CATI system supports reconciliation of 

critical errors as interviewers enter the data. After completion of interviewing for a quarter, post-CATI 

editing and data cleaning produce a final interview data file. The editing of the provider data begins with 

a manual review of returned immunization history questionnaires, data entry of the questionnaires, and 

cleaning of the provider data file. After the provider data are merged with the household interview data 

and responses from multiple providers for a teen are consolidated into a single vaccination history, the 

editing continues. A quality assurance check is performed based on the name, sex, and date of birth of the 

teen to ensure that the provider completed the questionnaire for the correct teen and to confirm ageeligibility (age 13 through 17 years at time of interview). Editing of the provider-reported vaccination 

dates then attempts to resolve specific types of discrepancies in the provider data. The end product is an 

analytic file containing household and provider data for use in estimating vaccination coverage.

 4.1. Data Preparation

The editing and cleaning of NIS-Teen data involve several steps. First, the CATI system enables 

interviewers to reconcile potential errors while the respondent is on the telephone. Further cleaning and 

editing take place in a post-CATI clean-up stage, involving an extensive review of data values, cross 

tabulations, and the coding of verbatim responses for race and ethnicity. The next step involves the 

creation of numerous composite variables. Provider data are cleaned in a separate step. After these steps 

have been completed, imputations are performed for item non-response on selected variables, and weights 

are calculated. The procedures and rules of the National Health Interview Survey serve as the standard in 

all stages of data editing and cleaning (http://www.cdc.gov/nchs/nhis.htm). 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 19

4.1.1. Editing in the CATI System 

The CATI software checks consistency across data elements and does not allow interviewers to enter 

invalid values. Catching potential errors early increases the efficiency of post-survey data cleaning and 

processing.

To prevent an overly complicated CATI system, out-of-range and inconsistent responses produce a 

warning screen, allowing the interviewer to correct errors in real time. This allows the interviewer to 

reconcile errors while the respondent is on the telephone. CATI warning screens focus on items critical to 

the survey, such as those that determine a teen’s eligibility (e.g., date of birth). 

A CATI system cannot simultaneously incorporate every possible type of error check and maximize 

system performance. To reconcile this trade-off, post-CATI edits are used to resolve problems that do not 

require access to the respondent, as well as unanticipated logic problems that appear in the data.

4.1.2. Post-CATI Edits

The post-CATI editing process produces final, cleaned data files for each quarter. The steps in this 

process, implemented after all data collection activities for a quarter are completed, are described below.

Initial Post-CATI Edits and File Creation

After completion of interviewing each quarter, the raw data are extracted from the CATI data system and 

used to create two files: the sample file and the interview data file. The sample file contains one record for 

each sampled telephone number and summary information for telephone numbers and households. The 

interview data file contains one record for each eligible sampled teen and all data the household reported 

for the teen. 

Following creation of these two files, a preliminary analysis of each file identifies out-of-range values and 

extraneous codes. The first check verifies the eligibility status of teens, based on date of birth and date of 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 20

interview. Once the required corrections are verified, invalid values are replaced with either an 

appropriate data value or a missing value code. 

Frequency Review

After the pre-programmed edits are run, frequency distributions of all variables in each file are produced 

and reviewed. Each variable’s range of values is examined for any invalid values or unusual distributions.

If blank values exist for a variable, they are checked to see whether they are allowable and whether they 

occur in excessive numbers. Any problems are investigated and corrected as appropriate. 

File Crosschecks

Crosscheck programs ensure that cases exist across files in a consistent manner. Specifically, checks 

ensure that each case in the interview data file is also present in the sample file and that each case in the 

sample file was released to the telephone centers. Checks also ensure that no duplicate households exist in 

the sample file and no duplicate teens exist in the interview data file. 

When all checks have been performed, the final quarterly interview data file is created. Programmers and 

statisticians then create composite variables constructed from basic variables for each teen. Sampling 

weights (described in Section 6 of this Guide) are added to each record.

4.1.3. Editing of Provider Data 

Six to eight weeks after the close of household data collection for a quarter, the majority of the

immunization history questionnaires have been collected from providers. The data from the hard-copy 

questionnaires are entered and independently re-entered to provide 100% verification. The provider data 

file is cleaned, in a similar fashion to the household data file, for out-of-range values and consistency. A 

computer program back-codes all “other shot” verbatim responses into the proper vaccine category (e.g., 

Recombivax counts as Hep B). These translations come from a file that contains all such verbatim 

responses ever encountered in the NIS-Teen. Also, the provider data file is checked for duplicate records, 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 21

and exact duplicates are removed. If the provider data contain a date of birth, sex, or name for the teen

that differs from the household interview for that teen, the questionnaire is re-examined to determine

whether it may have been filled out for the incorrect teen. Provider data that appear to have been filled out 

for the wrong teen are removed from the provider database. When a teen has data from multiple 

providers, decision rules are applied to produce the most complete picture of the teen’s vaccination

history.

Once these data have been cleaned, they are combined with the household data file. Information from up 

to eight providers can be added to a teen’s record. If more than one provider reported vaccination data for 

the teen, the data from the multiple provider reports are combined into a single history for the teen, called 

the “synthesized provider-reported vaccination history.” The determination of whether the teen is up-todate for recommended vaccines and vaccine series is based on the teen’s synthesized provider-reported 

vaccination history.

Many variables in the household data file are checked against or verified with the provider data file. For 

example, a teen’s date of birth as recorded by the provider is checked against the date of birth as given by 

the household, to verify that the provider was reporting for that specific teen and to form a “best” date of 

birth for the teen. 

 4.2. Limitations of Data Editing Procedures

Although data editing procedures were used for the NIS-Teen, the data user should be aware that some 

inconsistent data might remain in the public-use data file. The variables that indicate whether a teen is upto-date on each vaccine or series (on which the estimates of vaccination coverage are based) are derived 

from provider-reported data, and the NIS-Teen does not re-contact households or providers to attempt to 

reconcile potential discrepancies in provider-reported vaccination dates or to resolve date-of-birth 

reporting errors. However, the provider-reported data are manually reviewed and edited to correct specific 

reporting errors. Some adolescents considered to have adequate provider data may have incomplete 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 22

vaccination histories. These incomplete histories arise from three primary sources: 1) the household does 

not identify all vaccination providers, 2) some but not all providers respond with vaccination data, and 3) 

providers respond with vaccination data but fail to list all the vaccinations in the teen’s medical record.

Even with these limitations, the NIS-Teen overall is a rich source of data for assessment of up-to-date 

status and age-appropriate vaccination. Also, NIS-Teen is the only source to provide comparable 

provider-reported vaccination data across states and local areas in the United States. 

 4.3. Variable-Naming Conventions

The names of variables follow a systematic pattern as much as possible. The codebook for the public-use 

data file groups the variables into ten broad categories according to the source of the data (household or 

provider) and the content of the variable (NCIRD 2022). See Section 7 of this report for detailed 

information on the contents of the public-use data file.

 4.4. Missing Value Codes

Missing value codes for each variable can be found in the codebook (NCIRD 2022). For household

variables, the missing value codes usually are 77 for DON’T KNOW and 99 for REFUSED. Some 

household variables may also contain blanks, if the question was not asked. The variables developed from 

the immunization history questionnaire generally do not have specific missing value codes.

 4.5. Imputation for Item Non-Response

The NIS-Teen uses imputation primarily to replace missing values in the socioeconomic and demographic 

variables used in weighting. Missing values of these variables are imputed for all teens with a completed 

household interview – i.e., all teens appearing on the public-use data file. Missing values of health 

insurance variables are also imputed for teens with adequate provider data. A sequential hot-deck method 

is used to assign imputed values (Ford 1983). Class variables are used to separate respondents into cells. 

Donors and recipients must agree on the categories of the class variables, which include the estimation
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 23

area. Within the categories of the class variables, respondents are sorted by variables related to the 

variable to be imputed. The last case with an observed value is used as the donor for up to four recipients.

The variable labels in the codebook (NCIRD 2022) identify variables that contain imputed values. These 

variables include the sex, Hispanic origin, race, and health insurance status of the teen; the education 

level, age group, marital status, and mobility status of the mother; and the income-to-poverty ratio of the 

household.

 4.6. Vaccine-Specific Recoding of Verbatim Responses

On the IHQ, providers can list vaccinations in the “other” section of the IHQ shot grid. After data 

collection, these vaccinations are reclassified into the listed categories, if possible, using a vaccination 

recoding table. This table is reviewed by NCIRD personnel to ensure the vaccinations are recoded into the 

appropriate category or categories (for combination vaccinations).

 4.7. Subsets of the NIS-Teen Data

The NIS-Teen public-use data file contains data for all adolescents aged 13–17 years who have a 

completed household interview. An interview is considered complete if the respondent completed Section 

C of the questionnaire. As explained in Section 6 of this guide, each teen with a completed household 

interview is assigned a weight (RDDWT_C for the United States, excluding territories;

RDDWT_C_TERR for the United States, including territories) for use in estimation.

The NIS-Teen uses the synthesized provider-reported vaccination histories to form the estimates of 

vaccination coverage because the provider data are considered more accurate than household-reported 

data. Thus, the most important sub-set of the data consists of teens with adequate provider data. For these 

teens, one or more providers returned the immunization history questionnaire that included vaccination 

data. Unvaccinated teens are also considered to have adequate provider data. As discussed in Section 7

below, the PDAT2 variable identifies the teens with adequate provider data (PDAT2=1). These teens
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 24

have a separate weight (PROVWT_C for the United States, excluding territories; PROVWT_C_TERR 

for the United States, including territories), which should be used to form estimates of vaccination 

coverage (see Section 6).

 4.8. Confidentiality and Disclosure Avoidance

To prevent identification of participants in the NIS-Teen and the resulting disclosure of information, 

certain items from the questionnaires are not included in the public-use data file. In addition, some of the 

released variables either are top- or bottom-coded, or have their categories collapsed. Variable labels 

indicate which variables have been collapsed or recoded. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 25

5. Quality Control and Quality Assurance Procedures 

A major contributor to NIS-Teen data quality is its sample management system, which in 2021 managed 

over 230 estimation area by quarter samples and used a number of performance measures to track their 

progress toward completion. Important aspects of the quality assurance program for the RDD component 

of the NIS-Teen included on-line interviewer monitoring; on-line provider look-ups in a database system

integrated with the CATI system, including names, addresses, and telephone numbers of vaccination 

providers; and automated range-edits and consistency checks. These and other quality assurance 

procedures contributed to a reduction in total data collection cost by minimizing interviewer labor and 

overall burden to respondents. Khare et al. (2000), Khare et al. (2001), and the National Immunization 

Survey: Guide to Quality Control Procedures (CDC 2002) address quality assurance procedures. 

The Provider Record Check component used quality control measures at four junctions: prior to mailing 

packets to providers; during the telephone prompting effort; during the editing of returned questionnaires; 

and during and after their data entry. The final quality assurance activities were implemented during postprocessing of the returned questionnaires or vaccination records. All returned questionnaires were examined 

to identify and correct any obvious errors prior to data entry and then key-entered with 100% verification. 

The keying error rate is estimated, by way of a second verification process, to be less than 1%. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 26

6. Sampling Weights 

The two phases (RDD-phase and provider-phase) of data collection result in a separate sampling weight 

for each teen that has data at that phase. The RDD-phase sampling weights permit analyses of data from 

teens with completed household interviews. Each teen with adequate provider data (the subset of teens 

with completed household interviews on which official estimates of vaccination coverage are based) has a 

provider-phase sampling weight. In 2021, the RDD-phase sampling weight variable for producing 

estimates for teens with completed household interviews in the United States excluding territories is 

called RDDWT_C, and the RDD-phase weight variable for producing estimates for the United States 

including territories is called RDDWT_C_TERR. The provider-phase sampling weight variable for 

producing estimates for teens with adequate provider data in the United States excluding territories is 

called PROVWT_C, and the provider-phase weight variable for producing estimates for the United 

States including territories is called PROVWT_C_TERR. See Section 8 of this user’s guide for more 

information about the weights included in the data file and the proper way to use them. 

A sampling weight may be interpreted as the approximate number of teens in the target population that a 

teen in the sample represents. Thus, for example, the sum of the sampling weights of teens that are up-todate (on a particular vaccine or series of vaccines) yields an estimate of the total number of teens in the 

target population who are up-to-date. Dividing this sum by the total of the sampling weights for all teens

gives an estimate of the corresponding vaccination coverage rate. 

This section describes how these weights are developed and adjusted so as to achieve an accurate 

representation of the target population. The base weights reflect each telephone number’s probability of 

being selected into the sample; the adjustments take into account non-resolution of residential/nonresidential/non-working status of a telephone number, non-response to the screener, subsampling of one 

eligible teen in the household, non-response to the household interview, number of telephone lines in the 

household, raking for differential coverage rates, non-response by providers, and a final raking adjustment. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 27

6.1. Base Sampling Weight

In each quarterly NIS-Teen sample, each teen with a completed household interview receives a base 

sampling weight. The base sampling weight is equal to the inverse of the probability the phone number 

was sampled from the sampling frame for the quarter and estimation area.

6.2. Adjustments for Non-Resolution of Telephone Numbers and 

Screener Non-Response 

Non-response occurs in population-based surveys when respondents cannot be reached during the survey 

period, are not available at the time of the interview, or refuse to participate. Thus, the sum of the base 

sampling weights of teens with completed household interviews will underestimate the size of the target 

population in the estimation area, because not all sampled households respond to all stages of data 

collection up to the household interview. As a result, the base sampling weights must be adjusted so they 

can accurately reflect the number of teens in the target population that each sampled teen with a 

completed household interview represents. 

Some sampled households with age-eligible teens fail to complete the household interview because of 

unit non-response: for some telephone numbers, it is never determined whether or not the number is a 

working residential number despite multiple call attempts; for some households it is never determined 

whether or not the household contains age-eligible teens; and some households with age-eligible teens do 

not complete the household interview. To compensate for these types of unit non-response, the sampling 

weights of teens with a completed household interview are adjusted to account for the estimated number 

of age-eligible teens in households whose telephone numbers are never resolved; the estimated number of 

age-eligible teens in households that fail to complete the screening interview; and the estimated number 

of age-eligible teens in households that fail to complete the household interview because of unit nonresponse. Each of these adjustments is carried out within each estimation area by forming weighting cells 

based on the Metropolitan Statistical Area (MSA) status of the wire center associated with the cellular 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 28

phone number (MSA/non-MSA). Each of the non-response adjustments for territories was done at the 

estimation area level. That is, no weighting cells were formed for territories. Each cell in each stage of 

adjustment is ensured to have sufficient resolved/responding cases (usually 20) at that stage of 

adjustment. The cells with a deficient number of responding cases are collapsed into neighboring cells, 

i.e., both MSA categories are collapsed if either of the cells have a deficient number of responding cases. 

Once the adjustment cells are formed, the weights of the unresolved/non-responding records from the 

previous adjustment step are distributed to the weights of the resolved/responding records within each 

cell.

6.3. Adjustment for Subsampling of One Teen per Household

In households with more than one teen, only one teen is selected randomly per household for the NISTeen interview. The non-response adjusted age screener weight is adjusted to account for the teens that 

are not selected. Each household’s age screener weight is adjusted by multiplying it by the total number 

of eligible teens reported in the household (up to a maximum of 3). 

6.4. Adjustment for Interview Non-Response 

Some households that are determined to be eligible fail to complete the household interview for the 

selected teen. To compensate for this third type of unit non-response, the sampling weights of teens with a 

completed household interview are adjusted to account for teens who live in households that failed to 

complete the household interview. Similar to the first two types of unit non-response, the adjustment is 

carried out within estimation areas by forming weighting cells based on MSA status. For territories, the 

interview non-response adjustment was done at the estimation area level, i.e., no weighting cells were 

formed for the territory interview non-response adjustment. Each weighting cell for the interview nonresponse adjustment must have sufficient responding cases (usually 15); cells with a deficient number of 

responding cases are collapsed with neighboring cells, i.e., both MSA categories are collapsed if either of 

the cells have a deficient number of responding cases. Once the adjustment cells are formed, the weights 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 29

of the non-responding records from the previous adjustment step are distributed to the weights of the 

responding records within each cell.

6.5. Adjustment for Multiple Cellular Phones and Deriving Annual 

Weights

Once the non-response-adjusted interview weights for teens are computed, these weights are adjusted for 

additional cellular phones in the household. Because households with multiple cellular phones have a 

greater chance of being sampled, each teen’s household interview weight is adjusted by dividing it by the 

total number of cellular phones used by parents or guardians (up to a maximum of 3). 

Up to the previous step, the sampling weights are adjusted separately for each quarter, and the weights in 

each quarter pertain to the target population. However, annual vaccination coverage estimates are 

obtained from data for four consecutive quarters, so the weights in each quarterly file are adjusted when 

the data from the four quarters are combined. The adjustment factor is proportional to the number of 

households with completed household interviews in each quarter and estimation area. 

6.6. Post-Stratification 

Survey weights must be adjusted to provide weights for the full target population of teens aged 13 to 17 

years. Weights are first adjusted to population control totals by telephone status. Teens in dual landline 

and cellular phone households are adjusted to the population estimate of teens living in dual user 

households within each estimation area, and teens in cellular phone-only households within each 

estimation area are weighted to represent teens in cellular phone-only households. Teens in landline-only 

and phoneless households, which are excluded from the sample, are accounted for in the raking step 

described below.

The control totals used for the 2021 NIS-Teen are derived from a combination of 2020 census population 

estimates and the combined 2018, 2019, and 2020 one-year American Community Survey (ACS) data for 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 30

the United States and Puerto Rico, with adjustments for mortality, foreign immigration, and migration 

between states to produce population totals as of July 1, 2021. For the U.S. Virgin Islands and Guam, the 

control totals are derived from the 2010 Census data. The proportion of teens by detailed telephone status 

(landline-only, landline and cellular phone dual-user, cellular phone-only, phoneless) within each 

estimation area in the United States were derived using a similar small area modeling approach as 

described in Blumberg et al. (2011). These modeled telephone status estimates are applied to the control 

total for the total number of teens age 13 through 17 years in the estimation area to estimate the number of 

teens age 13 through 17 years by telephone status within the estimation area.

To reduce sampling variability and improve the precision of estimation, extreme weights are trimmed 

within an estimation area. RDD sampling weight values exceeding the median weight plus three times the 

interquartile range of the weights within an estimation area are truncated to that threshold. This weight 

trimming prevents teens with unusually large weights from having an unusually large impact on 

vaccination coverage estimates.

The final step in adjusting the RDD sampling weights is a raking adjustment (Deming 1943) of the 

trimmed, telephone status adjusted weights. The raking procedure uses estimation area-level control totals 

for maternal education categories, teen’s race/ethnicity, age group of the teen, sex of the teen, and 

telephone status. Raking makes it possible to incorporate additional variables into the weighting and to 

use more detailed categories for those variables. Briefly, raking takes each variable in turn and applies a 

proportional adjustment to the current weights of the teens who belong to the same category of the 

variable. After a number of iterations over all the variables, the raked weights have totals that match all 

the desired control totals. At this point, as before, the weights that exceed the median weight plus three 

times the interquartile range of the weights within an estimation area are truncated to that threshold. The 

raking step is applied again after the truncation of the weights and the weights are rechecked for extreme 

weights and truncated as before. The process is iterated up to five times. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 31

The sampling weights after all the foregoing adjustments constitute the “RDD sampling weights” 

(RDDWT_C for the United States excluding territories; RDDWT_C_TERR for the United States 

including territories). 

6.7. Adjustment for Provider Non-Response

Among the 43,707 teens with a completed household interview (excluding territories), 18,002

(41.2%) had adequate provider data. To maintain consistency with the adequate provider data 

definition used in previous years prior to the introduction of COVID-19 vaccines, adolescents were not 

considered as having adequate provider data if the only vaccinations reported were COVID-19 

vaccinations. The definition of teens with adequate provider data includes unvaccinated teens. These are 

teens for whom the respondent reported during the household interview that the teen had received no 

vaccinations and has no providers, or for whom one or more providers were reported but those providers 

reported administering no vaccinations. Among the 18,002 teens with adequate provider data, 103

were unvaccinated teens. Failure to obtain adequate provider data for the remaining 25,705 teens 

(58.0%) was attributable to: 

• parent or guardian not giving consent to contact the teen's vaccination provider(s) (48.3%);

• consent to contact vaccination providers obtained but no providers returned the immunization 

history questionnaire (6.0%); and

• one or more providers returned the immunization history questionnaire, but no providers reported 

any non-COVID-19 vaccination data, despite the parent or guardian indicating that the teen has 

received vaccinations (3.6%).

The 25,705 teens for whom a household interview was completed but adequate provider data were not 

obtained are classified as “partial non-responders” because they have only a partial response to the NISTeen as a whole.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 32

Empirical results for the NIS-Child suggest that children with adequate provider data have characteristics 

believed to be associated with a greater likelihood of being up-to-date, compared with children who had 

missing provider data. Specifically, children with adequate provider data are more likely to live in 

households that have higher total family income, have a white mother, and live outside a principal city of 

an MSA. Also, a child with missing provider data is less likely to live in the state where the mother lived 

when the child was born. These factors indicate a potential lack of continuity of health care, and are 

associated with lower vaccination rates (Coronado et al. 2000). An adjustment is made to the RDD 

sampling weights of the NIS-Child to account for these differences; otherwise, estimated vaccination 

coverage rates may be biased. A similar adjustment is also made to the RDD sampling weights of the 

NIS-Teen.

To reduce potential bias in estimators of vaccination coverage attributable to partial non-response, a 

weighting-class adjustment is used in each estimation area (Brick and Kalton 1996). This adjustment 

involves three steps. In the first step, sampled teens are classified according to the quintile of their 

estimated probabilities of having adequate provider data. In the statistical literature these probabilities are 

called response propensities (Rosenbaum and Rubin 1983, 1984; Rosenbaum 1987). Teens that have 

similar response propensities will also be similar with respect to variables that are strongly associated 

with the probability of having adequate provider data. In this important respect, teens in each class are 

comparable. Because of this comparability, any sub-sample of teens in a class may represent all teens in 

the class. Therefore, the weighting-class adjustment uses the teens with adequate provider data to 

represent all teens in the class. 

In the second step of this weighting-class adjustment, within each class an adjustment factor redistributes 

the RDD sample weights of the teens with missing provider data to the weights of the teens that have 

adequate provider data. These adjusted sampling weights of teens with adequate provider data are initial 

non-response-adjusted provider-phase weights.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 33

Within an estimation area, the sums of non-response adjusted weights of teens with adequate provider 

data for the various levels of important socio-demographic variables (such as race/ethnicity) may not be 

equal to corresponding population totals. To reduce bias attributable to these differences, raking was used 

in the third step to adjust the non-response adjusted weights to match estimation area control totals.

Control totals for these variables were estimated using the weighted totals from the sample of teens with 

completed household interviews. Smith et al. (2001b, 2005) describe the development of this approach in 

more detail. These raked weights of teens with adequate provider data are called “final provider-phase 

weights” (PROVWT_C for the United States excluding territories and PROVWT_C_TERR for the 

United States including territories). Because of the comparability of teens within each weighting class, 

any estimate that uses data only from the teens with adequate provider data, along with their providerphase sampling weights, will have less bias attributable to differences between teens with adequate 

provider data and teens with missing provider data.

Appendix B summarizes the distribution of the sampling weights in each estimation area.

7. Contents of the Public-Use Data File

The NIS-Teen public-use data file contains a record for each eligible teen for whom Section C of the 

household interview was completed, along with household-reported vaccination information and 

demographic information about the teen and the teen's mother. For teens with immunization history 

questionnaires containing vaccination data returned by one or more providers, the file also contains 

provider characteristic variables, as well as variables based on the teen's synthesized provider-reported 

vaccination history: the age of the teen at each vaccination, the number of each type of vaccination 

received, and indicators of whether the teen is up-to-date with respect to various recommended vaccines 

and vaccine series.

The public-use data file consists of ten sections, the contents of which are described below in detail. For 

additional information, users are encouraged to consult the codebook (NCIRD 2022). The codebook is 

divided into the ten sections described below and contains variable names, labels, and response 

frequencies (for categorical variables). The codebook also indicates the questionnaire item or items that

serve as the ultimate source for each variable and, for selected variables, gives additional information 

about the variable in the "Notes" field.

Before describing the sections of the public-use data file below, we first summarize the differences 

between the 2020 and 2021 NIS-Teen public-use data files:

• A new 2021 estimation area variable (ESTIAPT21) has been added and the 2020 estimation 

area variable (ESTIAPT20) has been dropped (see Table 5). Although data were collected 

for the U.S. Virgin Islands and Guam in 2021, teens in these areas are not included on the 

public-use data file in order to protect confidentiality. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 35

7.1. Section 1: ID, Weight, and Flag Variables

SEQNUMT is the unique teen identifier. (Because only one teen is selected per household, SEQNUMT

is also a unique household identifier.) PDAT2 indicates which teens are considered to have adequate 

provider data. As described in Section 6 of this report, RDDWT_C/RDDWT_C_TERR and 

PROVWT_C/PROVWT_C_TERR are the final household- and provider-phase weights, respectively. 

PROVWT_C/PROVWT_C_TERR should be used when analyzing the provider-reported data, i.e., the 

variables in Sections 7, 8, and 9 of the public-use data file.

7.2. Section 2: Household-Reported Vaccination and Health Information

As of 2017, all respondents are administered Section B of the household questionnaire, where they are 

asked whether they recall the teen getting flu, Td/Tdap, meningococcal, and HPV vaccinations, and for

the number of meningococcal and HPV vaccinations. 

Respondents are then administered Section C of the household interview, wherein information about the 

health of the selected teen and the teen's family, as well as demographic information about the teen and 

the teen’s mother, is collected.

Section 2 of the public-use data file contains vaccination information collected in Section B, and the 

health information collected in Section C of the household questionnaire. IMM_ANY indicates whether 

the respondent reported that the teen has had a vaccination of any type. For each type of vaccine asked 

about in Section B (excluding seasonal influenza), a set of variables stores the information collected about 

that vaccine type; additional variables store the responses to the health questions in Section C. 

The household-reported vaccination and health variables are described in more detail below. 

7.2.1. Household-Reported Tetanus Vaccine Variables 

Section B respondents that said the teen has received a vaccination of any type (IMM_ANY=1) are asked 

whether they recall the teen getting any Tetanus booster vaccinations. Variable TET_ANY indicates 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 36

whether any Tetanus booster vaccinations were reported for the teen. All respondents reporting that the 

teen has not received any Tetanus booster vaccinations are then asked the reason the teen didn't receive 

Tetanus booster vaccinations. Variables TET_REAS_1-TET_REAS_5, TET_REAS_7, and 

TET_REAS_10-TET_REAS_27 store the answers to this choose-all-that-apply question and reflect the 

coding of open-ended responses into the reason categories existing on the questionnaire as well as into 

newly-created reason categories. 

7.2.2. Household-Reported Meningococcal Vaccine Variables

Section B respondents that said the teen has received a vaccination of any type (IMM_ANY=1) are asked 

whether they recall the teen getting any meningococcal vaccinations, and if so, they are asked for the 

number of meningococcal vaccinations they recall. Variable MEN_ANY indicates whether any 

meningococcal vaccinations were reported for the teen. Variable MEN_NUM_TOT stores the total 

number of meningococcal vaccinations reported by the respondent. All respondents reporting that the teen 

has not received any meningococcal vaccinations, are then asked the reason the teen didn't receive 

meningococcal vaccinations. Variables MEN_REAS_1-MEN_REAS_7 and MEN_REAS_10-

MEN_REAS_26 store the answers to this choose-all-that-apply question and reflect the coding of openended responses into the reason categories existing on the questionnaire as well as into newly-created 

reason categories. 

7.2.3. Household-Reported Human Papillomavirus (HPV) Vaccine Variables 

Section B respondents that said the teen has received a vaccination of any type (IMM_ANY=1) are asked 

whether they recall the teen getting any HPV vaccinations, and if so, they are asked for the number of 

HPV vaccinations they recall. Variable HPVI_ANY indicates whether any HPV vaccinations were 

reported for the teen. Variable HPVI_NUM_TOT stores the total number of HPV vaccinations reported 

by the respondent.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 37

All respondents reporting that the teen has received a vaccination of any type (IMM_ANY=1), regardless 

of whether they reported the teen has received an HPV vaccination, are asked whether a doctor or other 

health care professional has ever recommended that the teen receive HPV vaccinations 

(HPVI_RECOM), and if so, the respondent is asked at what age the doctor recommended the teen should 

start receiving HPV shots (variable not included on the public-use file). 

All respondents reporting that the teen received fewer than the recommended number of HPV 

vaccinations (two if the teen is under 15 years of age, three if the teen is 15 years or older) are asked how 

likely it is that the teen will receive HPV vaccinations in the next twelve months (HPVI_INTENTR). 

Those responding "Not too likely", "Not likely at all", or “Not Sure/Don’t Know” are asked the reason the 

teen won't receive HPV vaccinations in the next twelve months. Variables HPVI_REAS_1-

HPVI_REAS_3, HPVI_REAS_5-HPVI_REAS_6, and HPVI_REAS_9-HPVI_REAS_32 store the 

answers to this choose-all-that-apply question and reflect the coding of open-ended responses into the 

reason categories existing on the questionnaire as well as into newly-created reason categories.

7.2.4. Household-Reported Health Variables 

All respondents are asked whether the selected teen has ever had the chicken pox (CPOX_HAD) and, if 

so, they are asked the age of the teen in years at the time when the teen had the chicken pox 

(CPOX_AGE). Those unable to give an exact age are asked to report an age range (CPOX_AGER). 

All respondents are then asked the age of the teen at the time of his or her last check-up (CKUP_AGE). 

If the teen's age at the last check-up was 13 years or more, the respondent is asked whether the teen had 

an 11-12 year old well-child exam (CKUP_11_12); if the respondent is unable or unwilling to answer 

this question he or she is asked whether or not the teen's last check-up was more than, exactly, or less than 

[age of teen - 12] years ago (CKUP_LAST). 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 38

All respondents are asked the number of times the teen has seen a health care professional in the last 12 

months (VISITS); whether the teen has been told by a health professional that he or she has asthma 

(ASTHMA); whether the teen has ever been told by a health professional that he or she has a lung 

condition other than asthma, a heart condition, diabetes, a kidney condition, sickle cell anemia or other 

anemia, or a weakened immune system caused by a chronic illness or by medicines taken for a chronic 

illness (RISK_EVER); whether the teen currently has any of these conditions (RISK_NOW); and 

whether any other members of the teen's household currently have any of these conditions (RISK_HH). 

Finally, the respondent is asked the number of times in the past 12 months the teen has missed school due 

to illness or injury (NOSCHOOLR). 

7.3. Section 3: Demographic, Socio-Economic, and Other 

Household/Teen Information

Section 3 of the NIS-Teen public-use data file consists of information collected during the household 

screening interview and the demographic information collected in Section C of the household main 

interview. To protect confidentiality, many of these variables have been collapsed, top-coded, or bottomcoded from the original, fully-detailed versions; the variable labels (see the public-use date file codebook) 

indicate which variables have been collapsed or recoded. 

AGE is the age of the selected teen in years based on the teen's best date of birth and the screener 

completion date, and SEX gives the sex of the selected teen, with missing values imputed. The language 

in which the interview was conducted is stored in variable LANGUAGE, and C5R gives the relationship 

of the respondent to the selected teen. 

C1R and CHILDNM give the number of people and children, respectively, in the household. 

The teen's Hispanic origin indicator, race with three categories, and race/ethnicity with four categories are 

presented in variables I_HISP_K, RACE_K, and RACEETHK, respectively; for each of these 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 39

variables, missing values have been imputed. EDUC_TR gives the teen's grade in school at the time of 

the interview.

The age, education level, and marital status of the mother of the selected teen are stored in variables 

AGEGRP_M_I, EDUC1, and MARITAL2 (married vs. not married), with missing values imputed.

The categorized total combined income for the teen's family is given by INCQ298A; INCPOV1 gives 

the family's poverty status (at or above poverty, income > $75,000; at or above poverty, income <= 

$75,000; below poverty; unknown), and INCPORAR gives the ratio of the family's income to the 

poverty level. INCPORAR_I gives the same ratio after missing values of family income have been 

imputed. Household tenure is given by RENT_OWN.

The number of landline telephone numbers in the household, the number of working cellular phones 

household members have available for personal use, and the number of these cellular phones that are 

usually used by parents or guardians are given by NUM_PHONE, NUM_CELLS_HH, and 

NUM_CELLS_PARENTS, respectively.

Variable CEN_REG gives the census region of the respondent's current residence, and MOBIL_Iindicates 

whether the mother's current state of residence is the same as her state of residence at the time of the teen's 

birth.

 7.4. Section 4: Geographic Variables

Variables ESTIAPT21 and STATE give the 2021 estimation area and state of residence, respectively, for 

each teen. EST_GRANT indicates which of the 50 states, District of Columbia, and 5 local areas that 

receive federal Section 317 immunization grants (Bexar County, TX; City of Chicago, IL; City of 

Houston, TX; New York City, NY; Philadelphia County, PA) the teen resides in. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 40

 7.5. Section 5: Number of Providers Identified and Consent Variables

Variable D7 indicates whether the respondent gave consent to contact the teen's providers. If D7=1, then 

consent was granted; if D7=2 then consent was explicitly denied; and if D7 is missing, consent was not 

granted because the respondent broke off the interview before being explicitly asked for consent. 

Variable D6R gives the number of providers identified by the respondent. Note that sometimes 

respondents report erroneous provider counts and sometimes report the same provider more than one 

time, and D6R does not reflect the cleaning or de-duplication of the initially-reported provider count.

Variable NUM_PROVR gives the number of providers identified for teens with consent to contact the 

providers and reflects the cleaning and de-duplication of the initially-reported provider count. For teens 

without consent, NUM_PROVR is set to 0.

 7.6. Section 6: Number of Responding Providers Variables

Variable N_PRVR indicates the number of providers returning IHQs with vaccination information for the 

teen. That is, N_PRVR is the number of IHQs that were returned for the teen that contain information on 

the IHQ shot grid.

 7.7. Section 7: Characteristics of Providers Variables

This section summarizes the information collected in IHQ questions 4, 5b, 6, and 7 across the teen's 

providers who returned IHQs.

WELLCHILD indicates whether the teen had an 11-12 year old well child exam or check-up based on 

responses to IHQ question 4. If any of the teen's providers that returned IHQs reported that the teen had a 

well child exam, then WELLCHILD=1. If all of the teen's providers that returned IHQs reported that the 

teen did not have a well child exam, then WELLCHILD=2. If none the teen's providers that returned 

IHQs reported that the teen had a well child exam, but at least one provider left the question blank or 

selected “Don’t Know”, or if no IHQs were returned for the teen, then WELLCHILD=3 (unknown). 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 41

FACILITY indicates the facility type of the teen's vaccination providers based on responses to IHQ 

question 5b. If all of the teen's providers that returned IHQs containing vaccination (i.e. shot grid) data 

(see Section 6 variable N_PRVR) reported their facility type to be:

● a public health department-operated clinic, community health center, rural health clinic, migrant 

health center, Indian Health Service-operated center, tribal health facility, or urban Indian health 

care facility, then FACILITY=1 (all public facilities);

● a hospital-based clinic, then FACILITY=2 (all hospital facilities);

● a private practice, then FACILITY=3 (all private facilities); 

● a military health care facility, WIC clinic, school-based health center, pharmacy, or other type of 

facility, then FACILITY=4 (all military/WIC/school/pharmacy or other facilities). 

If the responses of providers that returned IHQs containing shot grid data fell into more than one of the 

above bulleted categories, FACILITY=5 (mixed); otherwise, if at least one of the teen's providers 

returned an IHQ containing shot grid data, FACILITY=6 (unknown). If none of the teen's providers 

returned an IHQ containing shot grid data, FACILITY is set to missing.

The Vaccines For Children (VFC) program is a federally-funded program that provides vaccines at no 

cost to children who might not otherwise be vaccinated because of inability to pay

(http://www.cdc.gov/vaccines/programs/vfc/index.html). CDC buys vaccines at a discount and distributes 

them to awardees—i.e., state health departments and certain local and territorial public health agencies—

which in turn distribute them at no charge to those private physicians' offices and public health clinics 

registered as VFC providers. VFC_ORDER, based on responses to IHQ question 6, indicates whether the 

teen's vaccination providers order vaccines from a state or local health department to administer to 

children. If all of the teen's providers that returned IHQs containing shot grid data (see Section 6 variable 

N_PRVR) reported that they order vaccines from a state or local health department to administer to 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 42

children, then VFC_ORDER=1 (all providers); if at least one of the teen's providers that returned an IHQ 

containing shot grid data reported that the practice orders vaccines from a state or local health department 

to administer to children and the teen's other providers that returned IHQs containing shot grid data 

reported either that they did not order such vaccines or that they did not know whether or not they did, 

then VFC_ORDER=2 (some but possibly or definitely not all providers); if all of the teen's providers that 

returned IHQs containing shot grid data reported that they do not order vaccines from a state or local 

health department to administer to children, then VFC_ORDER=3 (no providers); if none of the 

conditions for VFC_ORDER=1, 2, or 3 was met but at least one of the teen's providers returned an IHQ 

containing shot grid data, VFC_ORDER=4 (unknown). If none of the teen's providers returned an IHQ 

containing shot grid data, VFC_ORDER is set to missing. Note that having a provider that orders VFC 

vaccine does not imply that the child is VFC-entitled; providers enrolled in the VFC program could also 

vaccinate children who are not VFC-entitled. 

REGISTRY is based on responses to IHQ question 7 and indicates whether the teen's vaccination 

providers reported the teen's vaccinations to a community or state immunization registry (also known as 

an Immunization Information System, or IIS). If all of the teen's providers that returned IHQs containing 

shot grid data (see Section 6 variable N_PRVR) indicated that they reported to a registry, then 

REGISTRY=1 (all providers); if at least one of the teen's providers that returned an IHQ containing shot 

grid data indicated that the practice reported to a registry and the teen's other providers that returned IHQs 

containing shot grid data indicated that they did not report to a registry, that they did not know whether or 

not they reported to a registry, or that the question is not applicable, then REGISTRY=2 (some but 

possibly or definitely not all providers); if all of the teen's providers that returned IHQs containing shot 

grid data indicated that they did not report to a registry or that the question is not applicable, then 

REGISTRY=3 (no providers); if none of the conditions for REGISTRY=1, 2, or 3 was met but at least 

one of the teen's providers returned an IHQ containing shot grid data, REGISTRY=4 (unknown). If none 

of the teen's providers returned an IHQ containing shot grid data, REGISTRY is set to missing.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 43

 7.8. Section 8: Provider-Reported Up-To-Date Vaccination Variables

This section contains vaccination count and up-to-date variables based on the teen's synthesized providerreported vaccination history. To facilitate data processing and to accommodate the large and continually 

growing number of vaccination types covered by the NIS-Teen, the provider-reported vaccination data are 

organized around the concept of vaccine categories and vaccine types within vaccine category. The 

vaccine categories correspond to the sections of the IHQ shot grid, and the vaccine types correspond to 

the type boxes on the IHQ shot grid. For each vaccine category, an "unknown" vaccine type is created for 

vaccinations that are reported without a type box being checked. Table 3 shows the vaccine categories 

and types for the 2021 NIS-Teen public-use data file. Provider-reported COVID-19 vaccination data 

were collected in 2021, but are not included on the 2021 NIS-Teen public-use data file to protect 

respondent confidentiality, as COVID-19 vaccines were only approved for adolescents for part of 

the year.

For each vaccine category, Section 8 of the public-use data file contains a variable named P_NUMYYY – 

where "YYY" is the vaccine category abbreviation given in Table 3 – that stores the number of 

vaccinations in that vaccine category in the teen's synthesized provider-reported vaccination history. For 

each vaccine category and type combination, Section 8 also contains a variable named P_NUMYYY_TT

– where "YYY" is the vaccine category abbreviation and "TT" is the vaccine type code given in Table 3 – 

that stores the number of vaccinations in that vaccine category of that vaccine type in the teen's 

synthesized provider-reported vaccination history.

For each P_NUMYYY and P_NUMYYY_TT variable described above, there are corresponding variables 

of the form P_N13YYY and P_N13YYY_TT that count only vaccinations that the teen received prior to 

age 13 years.

This section of the public-use data file also contains up-to-date indicators for a variety of recommended 

vaccines and vaccine series. These variables' names begin with "P_UTD"; the variable labels indicate 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 44

what is needed to be considered up-to-date for each variable, and the "Notes" field in the codebook shows 

the vaccine type codes (see Table 3) being included when determining whether the teen is up-to-date. For 

each "P_UTD" variable there is a corresponding variable whose name begins with "P_U13" that indicates 

whether the teen was up-to-date for the particular vaccine or vaccine series by age 13 years.

Note that it is possible that the administration of the NIS-Teen interview itself prompts some respondents 

to vaccinate their teens following the interview; to ensure that the vaccination rate estimates aren't 

artificially boosted because of this, the "P_NUM", "P_N13", "P_UTD", and "P_U13" variables in this 

section of the public-use data file count only vaccinations received before the date the household 

interview was completed.

This section also contains some additional UTD variables specific to human papillomavirus (HPV)

vaccines. P_UTDHPV11, P_UTDHPV12, and P_UTDHPV13 are conditional up-to-date indicators 

showing whether a teen has received exactly 1, exactly 2, or 3 or more HPV vaccinations, given that the 

teen has received at least one. Teens that have received no HPV vaccinations will have missing values for 

these variables. P_UTDHPV3C is the conditional HPV vaccination series completion indicator for the 3-

dose series. It indicates, among teens that have received at least one HPV vaccination, whether the teen 

completed the series of three doses. This variable is limited to teens with at least one HPV vaccination 

where the interview completion date follows the date of the first HPV vaccination by at least 6 months, as 

6 months is the minimum amount of time required to complete the 3-dose HPV vaccine series.

P_UTDHPV_15 indicates teens that either have received 3 or more HPV doses or have received 2 or 

more HPV doses with the 1st dose before age 15 years. P_UTDHPV_15INT indicates teens that either 

have received 3 or more HPV doses or have received 2 or more HPV doses with the 1st dose before age 

15 years and at least 5 months minus 4 days between the 1st and 2nd doses. P_UTDHPV3C_15INT is 

the conditional HPV vaccination series completion indicator for either the 3-dose or 2-dose series. This 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 45

variable uses the same criteria as P_UTDHPV_15INT, but is limited to teens with at least one HPV 

vaccination and 6 months between the first HPV dose date and the household interview date.

 7.9. Section 9: Provider-Reported Age-At-Vaccination Variables

This section contains variables storing the teen's age in years, months, and days at each vaccination in the 

synthesized provider-reported vaccination history, along with the vaccine types of those vaccinations.

For each vaccine category, variables YYY_AGE1 - YYY_AGE9 store the age in years of the teen when 

the vaccination was administered for up to nine vaccinations in the teen's synthesized provider-reported 

vaccination history, where "YYY" is the vaccine category abbreviation given in Table 3. Variables 

YYY_MAGE1 - YYY_MAGE9 store the age in months of the teen when each vaccination was 

administered. Variables YYY_DAGE1 - YYY_DAGE9 store the age in days of the teen when each 

vaccination was administered. For vaccine categories that contain multiple vaccine types, variables 

XYYYTY1 - XYYYTY9 give the corresponding vaccine type code (see Table 3). 

Unlike the vaccination count and up-to-date variables in Section 8 of the public-use data file, the variables 

in Section 9 include vaccinations given both before and after the household interview was completed. If 

desired, users can limit the Section 9 variables to only those before the household interview date by 

examining the corresponding Section 8 “P_NUM” variable and limiting the analysis of the Section 9 

variables to only the first n variables, where n is equal to the number of vaccinations in the vaccine 

category before the household interview date as indicated by the corresponding “P_NUM” variable. 

Users of the NIS-Teen public-use data file should be aware that the age-at-vaccination variables included 

in Section 9 may contain a small number of vaccination ages that are implausible according to the 

recommended immunization schedules (http://www.cdc.gov/vaccines/schedules/hcp/childadolescent.html). Such ages may arise if a medical provider inadvertently records an erroneous 

vaccination date or if a vaccination date is incorrectly transcribed onto an IHQ. The quality control 

procedures of the NIS-Teen address implausible ages to every extent possible. Suspicious dates are 

manually reviewed and corrected if there is evidence either from the household interview or from another 

provider that the date is incorrect. In rare cases, however, when there is no further information with which 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 48

to correct the reported vaccination date, the vaccination is treated as having actually occurred and the 

implausible age at vaccination persists on the data file. The data user should consider these issues in 

deciding how to analyze the NIS-Teen data.

7.10. Section 10: Health Insurance Module Variables

The Health Insurance Module (HIM) (Section E) gathers information on the health insurance coverage of 

the selected teen. Prior to 2016, seven variables containing HIM data were included in the NIS-Teen 

public-use data file: 

• TIS_INS_1: “Is the teen covered by health insurance provided through employer or union?”;

• TIS_INS_2: “Is the teen covered by any MEDICAID plan?”;

• TIS_INS_3: “Is the teen covered by CHIP?”;

• TIS_INS_3A: “Is the teen covered by any MEDICAID plan or CHIP?”;

• TIS_INS_4_5: “Is the teen covered by Indian Health Service, Military Health Care, TRICARE, 

CHAMPUS, or CHAMP-VA?”; 

• TIS_INS_6: “Is the teen covered by any other health insurance or health care plan?”; and

• TIS_INS_11: “Since age 11, was there any time when the teen was not covered by health 

insurance?”

In 2016, these variables were replaced by two health insurance variables, INS_STAT_I and 

INS_BREAK_I, which summarize the teen’s health insurance status and history across all of the 

insurance questions listed above, while also incorporating the imputation of missing values and coding of 

open-ended responses. In 2017, INS_STAT_I was replaced with INS_STAT2_I, which provides a 

different categorization of teens with both private and non-private, non-Medicaid insurance. 

INS_STAT2_I identifies the teen’s current health insurance coverage status. If the teen has a form of 

private health insurance and is not covered by any other type of health insurance, he/she is classified as 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 49

(1) Private only. If the teen is on any form of Medicaid, alone or in addition to other forms of insurance, 

he/she is classified as (2) Any Medicaid. If the teen is not covered by Medicaid but is covered by some 

other type of health insurance (including, but not limited to, CHIP, Indian Health Service, Military Health 

Care, TRICARE, CHAMPUS, or CHAMP-VA), either alone or in combination with private insurance, 

he/she is classified as (3) Other. If the teen is not covered by any kind of health insurance, he/she is 

classified as (4) Uninsured. 

INS_BREAK_I describes the teen’s coverage history since age 11 and indicates whether there have been 

any breaks in coverage during this period. A teen may be (1) currently insured but uninsured at some 

point since age 11, (2) currently insured and never uninsured since age 11, (3) currently uninsured but 

insured at some point since age 11, or (4) currently uninsured and never insured since age 11.

Both variables are available only for teens with adequate provider data who live in the non-territory 

United States.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 50

8. Analytic and Reporting Guidelines 

Data from the NIS-Teen public-use data file can be used to produce national, state, and estimation-area 

estimates of vaccination coverage rates using the PROVWT_C weight (PROVWT_C_TERR if 

territories are to be included). 

Information in the data file can also be used to calculate standard errors of the estimated vaccination 

coverage rates that reflect the complex sample design of the NIS-Teen. The file includes estimation area 

and state identifiers (ESTIAPT21 and STATE) as well as a stratum identifier, STRATUM. The sample 

is stratified by the 59 geographic estimation areas. 

Demographic and socioeconomic variables in the file can be used to obtain national vaccination coverage 

rates for sub-groups of the population. Data users should, however, be aware that estimates for such subgroups at the state or estimation area level will generally have large standard errors because of small 

sample sizes. The CDC standard for precision of sub-group estimates is that the ratio of the standard error 

to the estimate should be less than or equal to 0.3, and each analytic cell should contain at least 30 

respondents. 

 8.1. Use of NIS Sampling Weights

The 2021 NIS-Teen public-use data file contains two teen-level sets of weights. The RDDWT_C variable 

gives the household-phase weight for all teens in the United States excluding territories

(RDDWT_C_TERR if territories are to be included). These weights should be used to form estimates 

from teens with completed household interviews. The weights reflect the stratified sample design and also 

have been adjusted for unit non-response, for the selection of one teen per household, for the number of 

telephone lines in the household, for calibration to population control totals, and for the exclusion of nontelephone and landline-only teens. The weight variables PROVWT_C/PROVWT_C_TERR apply to 

teens with adequate provider data. These weights should be used to form estimates of vaccination 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 51

coverage using variables from Sections 7, 8, and 9 of the public-use data file (see Section 7 of this user's 

guide). Table 4 presents a summary of the appropriate weights and stratum variables to use for various 

types of analyses.

* Each weight will contain a missing value for all records that are not included in the population covered by the weight.

The NIS-Teen public-use data file does not contain any provider-level weights. The NIS-Teen does not 

sample providers directly; rather, they are included in the survey through the teens they vaccinate. A user 

of the file should not attempt provider-level analyses (e.g., estimate the percentage of providers in the 

United States that are private providers), because the NIS-Teen sample was not designed for that purpose.

 8.2. Estimation and Analysis

8.2.1. Estimating Vaccination Coverage Rates

Vaccination coverage rates are ratio estimators, as described in the statistical literature on methods for

complex sample surveys. Because of the adjustment to the sampling weights for provider-phase nonresponse, statistical analyses require only data from teens with adequate provider data (PDAT2 = 1), 

along with their final provider sampling weights (PROVWT_C/PROVWT_C_TERR). To summarize 

the statistical methodology by which vaccination coverage rates and their standard errors are obtained 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 52

from these data, let Yhi be an indicator, for the ith teen with adequate provider data in the hth stratum of 

the NIS-Teen sampling design, equal to 1 if the teen is up-to-date according to the provider data and 0 

otherwise. Also, let Whi denote the value of PROVWT_C/PROVWT_C_TERR for this teen. Then, 

letting and , the national estimator of the vaccination coverage rate may be 

expressed as

where L denotes the number of strata, and nh denotes the number of sampled teens with adequate 

provider data in the hth stratum. 

Letting L instead denote the number of strata in a state, the above formula can also be used to calculate 

vaccination coverage rates for states (regardless of whether the state contains only one or more than one

stratum). 

8.2.2. Estimating Standard Errors of Vaccination Coverage Rates 

The Taylor series method can be used to estimate the sampling variance of vaccination coverage rates for 

the U.S., the states, and estimation areas. Letting and

yields an estimator of the variance of the estimated vaccination coverage rate, , equal to

 . 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 53

The standard error is the square root of the variance. The estimation of standard errors for estimates of 

vaccination coverage rates in the NIS-Teen can be implemented in specialized statistical software such as 

SUDAAN (Research Triangle Institute 2008), SAS (SAS Institute Inc. 2009), R (Lumley 2010), and Stata 

(Stata Corporation 2009). Appendix C gives several examples of the use of SAS, R, and SUDAAN to 

estimate vaccination coverage rates and their standard errors for estimation areas and states. For all 

procedures, the option of with-replacement sampling of primary sampling units within stratum is used, 

because the sampling fractions for households within an estimation area are all quite small. For all 

estimates, the variable STRATUM is used as the stratum variable and the household/teen identifier 

(SEQNUMT) is used as the primary sampling unit identifier. The data file should be sorted first on 

STRATUM and then on SEQNUMT within STRATUM before running the programs for SUDAAN and 

SAS. 

8.3. Combining Multiple Years of NIS-Teen Data

8.3.1. Estimation of Multi-Year Means

With release of the 2021 NIS-Teen public-use data file, thirteen years of public-use NIS-Teen data are 

now available. The precision of estimates of vaccination coverage for sub-domains (e.g., by race/ethnicity 

of teen) within estimation areas or states can be improved by combining multiple years of NIS-Teen data.

Data users should, however, be aware that estimates from combined years of NIS-Teen data represent an 

average over multiple years. Although combining multiple years of NIS-Teen data will yield a larger 

sample size for estimation areas and states, the composition of the population in a geographic area may 

change over time, making interpretation of the results difficult. Furthermore, if vaccination administration 

schedules or vaccination coverage changes over time, the estimate of vaccination coverage for the 

combined time period applies to a hypothetical population that existed at the middle of the time period, 

making interpretation of the results even more difficult. Given the use of independent RDD samples in the 

NIS-Teen, it is also possible that a teen could appear in more than one public-use data file. Finally, given 

the change to the definition of adequate provider data in 2014 and its effect on NIS-Teen vaccination 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 54

coverage rate estimates as described in the introduction, users should exercise caution when interpreting 

results from a combination of years prior to 2014 with years 2014 and later. 

To estimate a multi-year mean for a given NIS-Teen variable, the weights in each participating file 

(RDD-phase weights RDDWT in 2008-2011, RDDWT_D in 2012-2017, and RDDWT_C in 2018-2021; 

and provider-phase weights PROVWT in 2008-2011, PROVWT_D in 2012-2017, and PROVWT_C in 

2018-2021) should be divided by the number of years being combined. For example, if data for 2017-

2021 for teens with adequate provider data are to be combined, then the weights in the five files – 

PROVWT_D in 2017 and PROVWT_C in 2018-2021 – should be divided by 5 to obtain revised 

weights, which should be saved as a new variable, say NEWWT. It is necessary to use NEWWT in the 

analysis to obtain correct weighted estimates for teens aged 13 to 17 years. Furthermore, the teen ID 

numbers (SEQNUMT) in the files are unique only within a year, not across years. It is important for the 

user to create revised, unique ID numbers when combining data from multiple years. 

The following SAS code can be used:

YRSEQT = 1 * (YEAR || SEQNUMT);

YEAR is the 4-digit year variable for the NIS-Teen data year (e.g., 2021). 

To produce valid estimates of sampling variability and valid confidence intervals for multi-year coverage 

rates and other multi-year means, it is necessary to use specialized software such as SAS, SUDAAN, R, 

or Stata. 

There is an important complication for variance estimation when combining multiple years, because some 

estimation areas are removed and other new areas are added each year (see Section 2 above for more 

information about rotating estimation areas). The variance strata for 2011-2021 are defined by the 

variables STRATUM_D (for 2011) and STRATUM (for 2012-2021), with STRATUM_D and 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 55

STRATUM being a combination of the estimation area variable for that year and the sampling frame 

(landline or cellular phone). The estimation area variables ESTIAPT11-ESTIAPT21 define mutually 

exclusive and exhaustive geographic areas. However, they are not exactly the same areas. For example, 

Dallas County, TX, was a separate estimation area in 2011, 2016, and 2019 but not in 2012-2015, 

2018, and 2020-2021. Tarrant County, TX, was a separate estimation area in 2018, but not in 2011-

2017 and 2019-2021. Other areas, such as New York City, NY and Rest of New York, are estimation 

areas in all years. 

To make inferences concerning multi-year means, the user must take two actions. First, he/she must 

define and save a new stratum variable with a common name for all years included in the analysis.

Second, he/she must define a common set of estimation domains that can be supported by each of the files 

included in the multi-year analysis. To take these actions, the user should follow the following seven-step 

procedure (or its equivalent):

i. Compute and save the new, common variance-stratum variable for each year participating in the 

analysis. The variable should be defined by the equation

STRATUMV = STRATUM_D, for teens in the 2011 public-use data file

= STRATUM, for teens in the 2012-2021 public-use data files 

ii. Compute and save the new, common weight variable, NEWWT, as instructed above for each year 

participating in the analysis.

iii. Compute and save the new, unique teen identification numbers, YRSEQT, as instructed above for 

each year participating in the analysis.

iv. Compute and save a variable defining the common estimation domains to be studied for each year 

participating in the analysis. For example, one could use the CDIAP (Common Denominator 

Estimation Area) variable set forth in Table 5 or states as geographic domains.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 56

v. Merge the multiple files into one consolidated file in a format compatible with the specialized 

software to be used.

vi. Sort the consolidated file by YEAR, STRATUMV, and YRSEQT. 

vii. Run the specialized software on the consolidated file, computing estimates, variance estimates, and 

confidence intervals. For SUDAAN users, sampling levels or stages may be specified by the 

statement

NEST YEAR STRATUMV YRSEQT / PSULEV = 3;

the specification of weights by 

WEIGHT NEWWT;

and the specification of estimation domains, for example, by the two statements

CLASS YEAR CDIAP STATE;

TABLES CDIAP; 

or 

CLASS YEAR CDIAP STATE;

TABLES STATE;

8.3.2. Estimation of Multi-Year Contrasts 

Considerations similar to those for multi-year means arise in the estimation of contrasts between NISTeen years. For example, a typical contrast of interest would be the difference between the vaccination

coverage parameters in 2020 and in 2021. As when combining multiple years of NIS-Teen data to 

estimate multi-year means, users should exercise caution when combining multiple years of data to 

estimate multi-year contrasts. The composition of the population in a geographic area may change over 

time, and it is possible that a teen could appear in more than one public-use data file. Furthermore, given 

the change in the definition of adequate provider data in 2014, users should be aware that NIS-Teen 

vaccination coverage estimates from 2014 and later, which use the revised definition, are not directly 

comparable to those from NIS-Teen 2013 and prior, which used the previous adequate provider data 

definition.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 57

To make inferences concerning a multi-year contrast, the user will need to work with the original weights 

reported on the files and store them in a common variable. One must not divide the original weights by 

the number of years included in the contrast. For the example, one may define the new, common weight 

variable as

NEWWT2 = PROVWT, if the teen is in the 2011 public-use data file

= PROVWT_D, if the teen is in the 2012-2017 public-use data files 

= PROVWT_C, if the teen is in the 2018-2021 public-use data files. 

The user should follow the seven-step procedure set forth in the section on multi-year means, using 

NEWWT2 in lieu of NEWWT. In SUDAAN, the user should also specify the contrast of interest 

through use of a CONTRAST statement or an appropriate regression model. For example, to compare the 

Td/Tdap-containing vaccine up-to-date estimate from 2020 to the 2021 estimate, SUDAAN users can use 

the following WEIGHT, VAR, and CONTRAST statements:

WEIGHT NEWWT2;

VAR P_UTDTD; 

CONTRAST YEAR = (-1 1);

9. Summary Tables 

Appendix E contains seven tables. Appendix Table E.1 lists the 59 estimation areas for the 2021 NISTeen by state. At the national level and for each state and estimation area, it provides the estimated 

population total of teens 13 to 17 years of age in 2021 and (from 2021 NIS-Teen data collection) the

number of teens with completed household interviews and number of teens with adequate provider data.

Appendix Tables E.2 through E.5 summarize pairs of variables: age of teen by maternal education 

(Appendix Table E.2), age of teen by family poverty status (Appendix Table E.3), race/ethnicity of teen 

by family poverty status (Appendix Table E.4), age of teen by race/ethnicity of teen (Appendix Table 

E.5), and age of teen by sex of teen (Appendix Table E.6). Each of these tables gives the unweighted and 

weighted counts of teens for whom the household interview was completed and the unweighted and 

weighted counts of teens with adequate provider data.

Appendix Table E.7 presents estimates of vaccination coverage and 95% confidence intervals obtained 

from SAS. The data user should obtain the same estimates from the 2021 NIS-Teen public-use data file. 

Appendix F shows the vaccine type codes used in the 2021 NIS-Teen public-use data file. 

Appendix G contains four tables and time-series charts. Table G.1 and Figure G.1 show key components 

of the NIS-Teen landline sample response rates and the landline sample CASRO response rates by year of 

the survey. Table G.2 and Figure G.2 show key components of the NIS-Teen cellular phone sample

response rates and the cellular phone sample CASRO response rates. Table G.3 and Figure G.3 show the 

CASRO response rates for the combined landline and cellular phone samples. Table G.4 and Figure G.4 

show vaccination coverage rate estimates since 2006. 

Appendix H presents key response rate components and the CASRO response rate by estimation area in 

the 2021 NIS-Teen.

10. Assessment of Total Survey Error in the NIS-Teen 

Assessing the validity of the NIS-Teen estimates of vaccination coverage is a critical and ongoing aspect 

of the NIS surveillance program. CDC frequently conducts evaluation studies and controlled experiments 

to understand the causes and impacts of sampling and nonsampling errors on the estimates and enable

formulation of methodological refinements that have the demonstrated capacity to improve data quality.

As landline phone use decreased and cellular phone use increased dramatically over the past decade, and 

the NIS-Teen transitioned first from a single-frame landline RDD sampling design to a dual-frame 

landline and cellular phone RDD design and then to a single-frame cellular phone RDD design, CDC has 

monitored the NIS-Teen estimates utilizing a Total Survey Error (TSE) approach.

TSE is the sum of the errors that arise at every step of a survey, including both sampling error and 

nonsampling errors such as sampling-frame coverage, nonresponse, and measurement errors (Mulry and 

Spencer, 1991). Pooling information from multiple evaluations of their precision and accuracy, we have 

conducted TSE analyses for the 2009-2013 NIS-Child and NIS-Teen data (Molinari et al. 2011; NORC 

2011; Pineau et al. 2012; Pineau et al. 2013; Skalland et al. 2016; Wolter et al. 2017b) and for the 2018-

2020 NIS-Child and NIS-Teen data (see the Data User’s Guides for the 2018-2020 NIS-Child and NISTeen public use data files). 

An assessment based on 2021 NIS-Teen data was conducted in 2022, with results summarized in 

this report.

Comparison of Demographic Distributions. Demographic distributions (age, sex, race/ethnicity, mother’s 

education, and mother’s age) among adolescents with adequate provider data were compared to 

benchmark values for adolescents age 13-17 derived from the U.S. Census Bureau’s Population Estimates 

Program (PEP) and American Community Survey (ACS) data. When using design weights that have 

not been calibrated to external population totals, demographic distributions as estimated by the 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 64

survey are generally close to the benchmark distributions. Before calibration, the NIS-Teen 

somewhat over-represented non-Hispanic White-only adolescents, under-represented non-Hispanic 

Black-only and Hispanic adolescents, and over-represented adolescents whose mothers are college 

graduates. When using final weights that have been calibrated to external population totals, the 

differences between survey estimates and population values narrowed, but the 2021 NIS-Teen still 

over-represented adolescents whose mothers are college graduates (44.3% in survey, 36.5% in 

population) and under-represented adolescents whose mothers have some college but not a fouryear degree (22.8% in survey, 30.6% in population). 

Comparison to IISAR Vaccination Coverage Rates. Next, NIS-Teen vaccination coverage rate estimates 

were compared to vaccination coverage rates reported in the Immunization Information Systems Annual 

Report (IISAR). Sponsored and conducted by NCIRD, the IISAR is an annual assessment of

immunization information systems (IIS)3 activity among the 64 immunization program awardees, which 

include the 50 states, 6 cities (Chicago, District of Columbia, Houston, New York City, Philadelphia, and 

San Antonio), and 8 U.S. territories. To evaluate each awardee’s performance, the immunization program 

manager in the awardee area is asked to complete a self-administered, web-based questionnaire asking for 

demographic and immunization information, public and private provider site participation levels, and 

information about achievement of IIS functional standards. NCIRD provides competitive supplemental 

funds to awardees that met high data timeliness and participation (child and adolescent) in the IIS. During 

the period 2013-2017, six awardees were recognized as IIS sentinel sites, including Michigan, Minnesota, 

North Dakota, New York City, Oregon, and Wisconsin. Because of increased timeliness and higher child 

and adolescent saturation levels in the IIS, vaccination coverage rates reported in IISAR by sentinel sites 

are thought to be relatively more accurate than vaccination rates reported by non-sentinel sites.

3 State IIS are computer databases that aspire to contain information about all of the doses of all vaccines 

administered to all children resident within the state. State IIS vary in their completeness of both children included 

and the doses they received.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 65

NIS-Teen vaccination coverage rate estimates were found to be generally higher than IISAR 

vaccination coverage rates, but for the six sentinel sites reasonably good agreement was observed 

between NIS-Teen and IISAR rates. Further, the adolescent participation rate – the proportion of 

adolescents in the IIS jurisdiction with two or more vaccine doses in the IIS database4

 – was 

determined to be a reasonable indicator of the quality of the corresponding IIS database, as the IIS 

vaccination coverage rate was found to increase as the adolescent participation rate increased. It 

was also observed (Figure 1) that the difference between NIS-Teen and IISAR vaccination coverage 

rates declines as the adolescent participation rate increases (i.e., as the quality of the IIS increases). 

These findings are consistent with the view that IIS vaccination coverage rates converge towards 

NIS-Teen vaccination coverage rates as the quality of the IIS increases.

Vaccination Coverage Rates for One or More Doses of Tdap vs. IIS Adolescent 

Participation Rate (APR) with Regression Line: 56 Estimation Areas

4 When setting the denominator for the participation rate calculation, some IIS use an external estimate of the 

number of adolescents living in the jurisdiction rather than a count of adolescents in the IIS itself; this results in 

some IIS reporting a participation rate of over 100 percent.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 66

Comparison of Health Insurance Distributions. NIS-Teen health insurance distributions were compared 

to similar distributions produced by the Current Population Survey (CPS), the National Health Interview 

Survey (NHIS), and the American Community Survey (ACS). All of these surveys use somewhat 

different definitions of insurance status and report for different age ranges of adolescents. Nevertheless, 

we found the NIS-Teen distributions to be broadly similar to those from the CPS, NHIS, and ACS, 

but with some differences. NIS-Teen estimates of percent of adolescents with any public insurance 

(41.8% in 2020, 41.0% in 2021) were higher than the corresponding benchmark estimates (37.2% 

(NHIS), 34.3% (CPS), and 37.5% (ACS) in 2020; 34.8% (CPS) in 2021), and the NIS-Teen

estimates of uninsured adolescents (4.1% in 2020, 3.0% in 2021) were lower than the estimates 

from the benchmark surveys (6.6% (NHIS), 6.4% (CPS), and 5.9% (ACS) in 2020; 6.7% (CPS) in 

2021). 

Comparison to State Immunization Surveys. A comparison was undertaken of NIS-Teen vaccination 

coverage rate estimates to estimates from immunization surveys in two states: the 2017 and 2018 

Georgia Adolescent Immunization Survey (GIS) (Machado, 2017; Machado, 2018) and the 2011-

2016 Kansas Behavioral Risk Factor Surveillance Survey (Kansas BRFSS) (Gillespie, 2018). GIS 

and NIS-Teen, and Kansas BRFSS and NIS-Teen, displayed reasonably similar vaccination 

coverage rates for 1+ Tdap and 1+ MenACWY. For males and females both separately and 

combined, NIS-Teen vaccination coverage rates for up-to-date (UTD) HPV5 were substantially and 

statistically significantly higher than the corresponding rates from GIS and Kansas BRFSS. In the 

case of GIS, this finding is likely due to differences between the GIS and NIS-Teen in adolescent age 

at HPV assessment, and in the case of Kansas BRFSS, to incomplete reporting by the parental 

respondents in the Kansas BRFSS. 

5 Throughout this section, UTD HPV is defined as receiving at least three doses of HPV vaccine, or at least two 

doses if the first dose was before age 15 and at least 5 months minus 4 days elapsed between the first and second 

doses.
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 67

Next, an assessment of all sources of error in the 2021 NIS-Teen was conducted, including sampleframe coverage error, nonresponse error, and measurement error; the component errors were then 

combined to assess total survey error. The change in total survey error between the 2020 NIS-Teen

and 2021 NIS-Teen was also estimated.

Coverage Error. The NIS-Teen cellular phone RDD sampling frame fails to cover the landline-only and 

phoneless populations; vaccination coverage rates in the former were estimated using data collected in the 

2017 NIS-Teen and vaccination coverage rates in the latter were estimated using data collected in the 

2012 NHIS Provider Record Check. The vaccination coverage rates in the landline-only population 

tended to be less than the vaccination coverage rates in the population covered by the cellular phone

sampling-frame, and the results were somewhat mixed with regard to the phoneless population. Because 

the sampling-frame uncovered population is so small relative to the covered population, however, mean 

sampling-frame coverage error was estimated to be 0.3 percentage points or less for 1+ Tdap, 1+ 

MenACWY, and UTD HPV.

Nonresponse Error. Nonresponse error in the 2021 NIS-Teen was assessed through comparison of 

the 2021 NIS-Teen to the cellular phone domain within the 2019 NHIS. (The assessment was made 

using 2019 NHIS because 2020 data collection methods were modified in response to the COVID-19 

pandemic, resulting in lower response rates, and 2021 NHIS data were not available at the time of 

the analysis.) NHIS does not offer direct estimates of vaccination coverage rates. Instead, a model-based 

technique was used to impute NHIS vaccination status, and then the resulting NHIS vaccination coverage 

rates (treated as vaccination coverage rates void of nonresponse error) were compared to NIS-Teen

vaccination coverage rates, with the difference treated as nonresponse error in the NIS-Teen. Despite 

nonresponse in the 2021 NIS-Teen, including household nonresponse, non-consent to contact 

vaccination providers, and provider nonresponse, mean nonresponse error in vaccination rates was 

estimated to be modest (less than 0.8 percentage points for 1+ Tdap and 1+ MenACWY, and UTD 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 68

HPV estimates when using either design weights or final weights that account for the survey’s 

nonresponse adjustment) and not statistically significant at the 0.05 level. 

Measurement Error. A form of measurement error called “provider under-reporting” was assessed. 

Sometimes called “under-ascertainment,” provider under-reporting error arises when an adolescent with 

adequate provider data is truly vaccinated but is reported as unvaccinated for one or more recommended 

doses in the adolescent’s provider-reported vaccination history. Under-reporting error can occur if the 

household respondent fails to nominate all of the adolescent’s vaccination providers, if one or more of the 

adolescent’s nominated vaccination providers fails to report a vaccination history for the adolescent, or if 

one or more of the adolescent’s nominated providers reports a vaccination history but fails to report all of 

the vaccinations the adolescent has received. Underreporting error was estimated using data from 

projects sponsored by CDC in which the 2017 NIS-Teen sample of adolescents in 19 jurisdictions 

and the 2019 NIS-Teen sample of adolescents in six jurisdictions were matched to the state or local

IIS for the jurisdiction. In this work, the standard of truth for a given adolescent is taken to be the 

synthesis of the NIS-Teen and IIS vaccination histories. In prior studies conducted in 2012, 2013, 2018, 

2019, and 2020 using similar methods, measurement error was found to be the largest component of error 

in the NIS-Teen vaccination coverage rate estimates for most vaccines. Similar conclusions were 

reached for the 2021 NIS-Teen, where it was estimated that measurement error decreased observed 

vaccination coverage rates by about 2 to 5 percentage points.

Total Survey Error. Finally, all of the component errors were combined to assess the distribution of total 

error in the NIS-Teen vaccination coverage rates, using a Monte Carlo technique. The mean of the 

distribution is an estimate of the total error, and the 2.5 and 97.5 percentiles of the distribution form a 

95% credible interval for the total error. The estimated component errors and total survey errors are 

presented in Table 6. For the ≥1 Tdap vaccination coverage rate, the mean of the TSE distribution

was found to be -4.5 percentage points with a 95% credible interval of (-6.4, -2.0) percentage points. 
Data User’s Guide for the 2021 NIS-Teen Public-Use Data File Page 69

That is, the NIS-Teen ≥1 Tdap vaccination coverage rate was on average about 4.5 percentage 

points too low. For the ≥1 MenACWY vaccination coverage rate, the mean of the TSE distribution

was found to be -3.7 percentage points with a 95% credible interval of (-5.7, -1.3) percentage points.

For UTD HPV, the mean of the TSE distribution was found to be -2.5 (-5.8, 0.9) percentage points

overall, -2.3 (-6.8, 2.5) percentage points for females, and -2.6 (-7.0, 1.8) percentage points for males. 

The credible intervals for UTD HPV all contain zero, which signifies that the statistical evidence is 

consistent with the hypothesis that mean total error is near zero. Nevertheless, according to best 

estimates, under-ascertainment of the provider-reported vaccination history is the largest source of 

error for all vaccines. 

Change in Total Survey Error. Change in TSE between the 2020 and 2021 NIS-Teen was measured 

using the bridging cohort method introduced by NCIRD (Yankey, Hill, Elam-Evans, et al. 2015). 

Each survey year includes adolescents born within 24 quarterly birth cohorts. Every pair of adjacent 

survey years spans 28 quarterly birth cohorts, of which 20 are in common and 8 are not in common. The 

common birth cohorts are the bridging cohort, and for 2020 and 2021, the bridging cohort extends 

from adolescents born in January 2003 through adolescents born in December 2007. 

Consider a vaccination coverage rate estimated from the bridging cohort as of a given adolescent age, 

such as 13 years. Two estimates are possible, one using the sample of adolescents in the bridging cohort 

within the 2020 NIS-Teen sample and the second using the corresponding sample of adolescents within 

the 2021 NIS-Teen sample. Ideally, the two estimators should exhibit the same statistical expectation (i.e., 

average value in hypothetical repeated sampling). A large difference between the two estimates may 

signal a change in the statistical expectation from one survey year to the next, which could result from a 

change in the distribution of sampling-frame coverage error, nonresponse error, or measurement error. 

Differences may also result simply from the effects of random sampling error.

For 1+ Tdap by age 13 years, 1+ MenACWY by age 13 years, and UTD HPV by age 13 years, the 

differences between the 2020 and 2021 national-level vaccination coverage rate estimates for the 

bridging cohort were small, and no differences were found to be statistically significant at the 0.05 

level. The difference between the 2021 estimate and the 2020 estimate for the bridging cohort was -

0.1 percentage points for 1+ Tdap, 0.2 percentage points for 1+ MenACWY, 1.5 percentage points 

for UTD HPV overall, 0.8 percentage points for UTD HPV among females, and 2.2 percentage 

points for UTD HPV among males. Overall, the results suggest there is little statistical evidence of a 

change in total survey error between 2020 and 2021.

11. Limitations 

The findings in this report are subject to at least four limitations. First, because NIS-Teen is a telephone 

survey, results are weighted to be representative of all adolescents aged 13 through 17 years. Although 

statistical adjustments were made to account for non-response and households without cellular phones, 

some bias might remain. Second, underestimates of vaccination coverage might have resulted from the 

exclusive use of provider-reported vaccination histories because completeness of these records is 

unknown. Third, although national estimates of vaccination coverage are precise, estimates for state and 

local areas should be interpreted with caution because their sample sizes are smaller and their confidence 

intervals generally are wider than those for national estimates. Finally, analysis of trends across data years 

that span from 2010 and earlier to 2011-2017 and from 2011-2017 to 2018-2021 are subject to potential 

bias that may remain after weighting adjustments because of the switch from landline to dual landline and 

cellular phone frames in 2011, and from dual landline and cellular phone frames to a single cellular phone

frame in 2018 (Nguyen et al. 2019). In addition, analysis of trends across data years that span from 2011 

to 2017 are subject to potential bias that may remain after weighting adjustments because of the

expansions and reductions of the share of the total sample that came from the cellular phone frame across 

these years and because of the change in the definition of adequate provider data in 2014.

Samples by Survey Year, National Immunization Survey - Teen, 2011-2017*

* Excludes U.S. territories. The landline sample was removed from the NIS sample design beginning in 2018.

The response rate is the number of households with a completed household interview divided by the 

estimated number of eligible households in the sample. Within each sample type (landline or cellular

phone), the number of eligible households was estimated using the CASRO assumptions; these 

assumptions are that the rate of households among the unresolved telephone numbers is the same as the 

observed rate of households among the resolved telephone numbers, and the rate of eligible households

among unscreened households is the same as the observed rate of eligible households among screened 

households. Under these assumptions, within each sample type the CASRO response rate is equal to the 

product of the resolution rate, the screener completion rate, and the interview completion rate. For the 

combined samples, we have defined the CASRO response rate as the total number of households with a 

completed interview divided by the estimated total number of eligible households across both sample 

types, where the estimated total number of eligible households is equal to the sum of the estimated 

number of eligible households in the landline sample (using CASRO assumptions) and the estimated 

number of eligible households in the cellular phone sample (using CASRO assumptions). Table G.3 

presents the CASRO response rate calculated in this way for the combined landline and cellular phone

samples, by survey year, and Figure G.3 presents a graphical representation. Because the CASRO 

response rate is lower for the cellular phone sample than for the landline sample, the CASRO response 

rate for the combined landline and cellular phone samples was lower in years with a larger cellular phone

sample and higher in years with a smaller cellular phone sample.
