# Introduction
Thi s report provide s detailed data from the 199 6 National Health Interview Survey (NHIS ) on the health of the civilian noninstitutionalized population. Estimate s are presented on acute conditions , episode s of person s injured, restriction in activity, prevalence of chronic conditions , limitation of activity due to chronic conditions, respondent-assessed health status , and the use of medical services—including physician contacts and short-stay hospitalization
. In addition , a special section in the text presents selected trends in health statistic s for 1982–96 , a period during which the basic NHIS questionnaire and field procedure s were stable
. A basic redesign of the NHIS questionnaire s and field procedure s was implemented in 1997. Estimate s of these health characteristic s are shown in table s 1–78 for variou s group s in the population, including thos e defined by age , sex, race , and family income (each shown for specific age groups) , and by geographic region and place of residence
. Estimate s for other characteristic s of special relevance to particular health measure s are also included
. For example , estimate s of physician contacts are shown by the place where the contact occurred. The ‘ ‘Selected Results and Us e of T

ables ’ ’ section include s a brief definition of each health characteristic included in table s 1–7 8 and reports the 199 6 estimate for each characteristic. Previou s issue s of thi s annual report included text table s that presented comparisons with the corresponding estimate s from the previou s two years and standardized rate s for each of the major health characteristics
. Because the primary focu s of thi s report i s to provide data from the current survey, thes e table s have been eliminated. However, selected significant dif ferences between the 199 6 and 199 5 estimates are presented in the text. The NHIS data are often used to monitor trends
. Such analyse s must addres s change s in the survey design over time
. In 1982 , the NHIS questionnaire and data preparation procedure s of the survey were extensively revised
. The basic concepts of NHIS changed in some cases , and in other case s the concepts were measured in a dif ferent way. Comparisons with earlier results should not be undertaken without carefully examining these changes

## Series 10, No. 150 (1). In 1985, a new sample design for NHIS and a different method of presenting sampling errors were introduced (2). In 1995, another change in the sample design was introduced, including the oversampling of black and Hispanic persons (3). In addition, during 1996, the use of part of the sample for the development and testing of a Computer Assisted Personal Interview (CAPI) system for use in 1997 resulted in a reduced sample size. Because of these differences among surveys from different years, it is recommended that users consult appropriate technical reports for NHIS data years prior to 1985 (2) and appendix I for 1985 and later. Although published reports are one of the primary methods of disseminating estimates from NHIS, data also are available in standardized microdata tapes. Tapes containing information from the NHIS core questionnaires from 1969 through 1996 are available for purchase from the National Technical Information Service (NTIS), 5285 Port Royal Road, Springfield, VA 22161. Public use tapes also are available for special topics included in NHIS from 1973 through 1996. Information about the cost and availability of these tapes can be obtained from the National Center for Health Statistics, Division of Health Interview Statistics, Systems and Programming Branch, 6525 Belcrest Road, Hyattsville, MD 20782. Public use microdata on compact disk read-only memory (CD-ROM) are available for the NHIS core and special topic data for 1987 through 1996. They can be purchased through the NTIS or from the Government Printing Office (GPO), Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Questions about CD-ROM data files should be directed to the National Center for Health Statistics (NCHS), Data Dissemination Branch, at 301-436-8500. Information on recent publications is available on the NCHS homepage on the Internet at http://www.cdc.gov/nchswww. For specific NHIS information, such as description of the survey, queried topics, variables, selected data highlights, and questionnaires, among other items, the Internet address is http://www.cdc.gov/ nchswww/about/major/nhis/nhis.htm
. The special topics included in the 1996 NHIS covered the following two areas: Immunization (asked of sample children under 6 years of age, including hepatitis B); and Family resources (including access to care, health care coverage, private plan and coverage detail, and income and assets). Data from the special health topics and core in 1996 were collected throughout the entire year. However, as mentioned earlier, due to the introduction and testing of the CAPI system for use in 1997, the sample size was reduced. The Immunization questionnaire collected information on a sample child under age 6 years and on all children 19–35 months of age in each family with age-eligible children. The Family Resources questionnaire asked about all family members. 

# Source and Limitations of Data
Information from the National Health Interview Survey (NHIS) in this report is based on data collected in a continuing nationwide survey by household interview. Each week a probability sample of the civilian noninstitutionalized population of the United States is interviewed by personnel of the U.S. Bureau of the Census. Information is obtained about the health and other characteristics of each member of the household. Part of the 1996 NHIS sample was used for testing of the computer-assisted personal interview (CAPI) system that was implemented for the 1997 NHIS. The CAPI test cases are not included in the 1996 NHIS data set used to produce the estimates in this report. Relative to 1995, the 1996 NHIS sample size was reduced by approximately 25% in the first and second quarters, and by approximately 50% in the third and fourth quarters. The interviewed sample for 1996 consisted of 24,371 households containing 63,402 persons. The total noninterview rate was 6.2% : 4.1% was the result of respondent refusal, and the remainder was primarily the result of failure to locate an eligible respondent at home after repeated calls, as described in appendix I
. For a detailed list of changes to the basic health and demographic questionnaire that have occurred since 1985, see appendix I . A description of the new survey design implemented in 1995, along with methods used in estimation and general qualifications of the data obtained from the survey, also are presented in appendix I
. All information collected in the survey is from reports by responsible family members residing in the household. When possible, all adult family members participate in the interview. However, proxy responses are accepted for family members who are not at home and are required for all children and for family members who are physically or mentally incapable of responding for themselves. Although a considerable effort is made to ensure accurate reporting, the information from both proxy respondents and self-respondents may be inaccurate because the respondent is unaware of relevant information, has forgotten it, does not wish to reveal it to an interviewer, or does not understand the intended meaning of a question. Because the estimates in this report are based on a sample of the population, they are subject to sampling errors. Therefore, readers should pay particular attention to ‘‘Reliability of the Estimates’’ in appendix I of this report, which shows formulas for calculating standard errors along with instructions for their use. The estimated standard error parameters, relative standard error cut-off points, and r-squared values presented in table II in appendix I in this report were derived from 1996 data. Regarding statistics in this report that are based on earlier years of NHIS, readers should consult table II in appendix I of the Current Estimates for the years 1982–95 for the standard error parameters and cut-off points (1, 2, 4–15). In this report, terms such as ‘‘similar’’ and ‘‘no difference’’ mean that there is no statistically significant difference between the measures being compared. Terms relating to difference (for example, ‘‘greater than’’ or ‘‘less Page 2 [ Series 10, No. 200

## than’’) indicate that differences are statistically significant. Two-tailed individual t-tests, with a critical value of 1.96 (0.05 level of significance) were used to test all comparisons. These tests did not take multiple comparisons into account. Lack of comment regarding the difference between any two statistics does not mean that the difference was tested and found to be not significant. The major concepts for these estimates are described in appendix II , and the questionnaires and flashcards used in the interview are shown in appendix III . Illnesses and injuries are coded using a modified version of the Ninth Revision of the International Classification of Diseases (16). The Division of Health Interview Statistics of NCHS should be contacted for information about the coding and editing procedures used to produce the final data file from which the estimates shown are derived. 

# Selected Results and Uses of Tables In the following sections, each of the health-related characteristics included in this report is defined and the overall 1996 estimates are presented. Although previous issues of this report included tables comparing current estimates with those from earlier years, they have been eliminated in this report. However, some comparisons are noted where large differences have been observed between the 1996 and 1995 estimates for the same characteristic. Readers wanting more extensive comparisons for the 1995 estimates should refer to Series 10, No. 199 (15). Readers comparing subgroups of the population in tables 1–78 may want to consider the possible effect of age in comparing subgroups. For sociodemographic characteristics for which the age distribution of the subgroups may differ significantly (such as sex, race, and family income), results are shown for specific age groups. However, for geographic region and place of residence, there is generally little difference in the age distributions of the subgroups. Therefore, these results are not shown for specific age groups. Tables 1–77 show detailed results for health characteristics. The population figures used to calculate the rates are in table 78
. 

# Acute Conditions: Incidence, Medical Attention, and Associated Restriction in Activity An acute condition is defined for the National Health Interview Survey (NHIS) as a type of illness or injury that ordinarily lasts less than 3 months, was first noticed less than 3 months before the reference date of the interview, and was serious enough to have had an impact on behavior. Only two types of impact are considered: (a) the illness or injury caused the person to cut down on daily activities for at least half a day, or (b) a physician was contacted regarding the illness or injury. 

# Incidence Incidence rates for acute conditions by type of condition and sociodemographic characteristics are shown in tables 1–5 , and incidence (number) is shown in tables 6–10 . The 1996 rate of 163.5 acute conditions per 100 persons per year was not significantly different from the 1995 rate of 174.4. For four broad types of acute conditions, the 1996 incidence rates per 100 persons per year rank as follows: respiratory conditions (78.9), injuries (21.7), infective and parasitic diseases (20.5), and digestive system conditions (6.7). Although the 1996 rate (78.9) for respiratory conditions appears to be lower than the rate in 1995 (85.2), primarily due to less influenza activity, no statistical difference was found for overall respiratory conditions. The rate for influenza (36.0), however, is significantly lower than the corresponding rate for 1995 (41.2). 

# Medical Attention Estimates of the percent of acute conditions that were medically attended are shown in tables 11–15 . During 1996, an estimated 67.9% of acute conditions reported in the NHIS were medically attended. Of the four broad types of acute conditions, injuries were most likely to have been medically attended (91.4% ), and respiratory conditions were least likely to have been medically attended (51.1% ). 

# Restricted Activity Associated with Acute Conditions Four types of restricted activity resulting from illness, injury, or impairment are measured in NHIS: days lost from work for currently employed persons 18 years of age and over, school days missed by youths 5–17 years of age, days spent in bed (which may overlap either of the preceding types), and other days on which a person cuts down on daily activities. Estimates of ‘‘cut-down’’ days are not presented separately, but are included in the generic concept of ‘‘restricted-activity days.’’ The other three types of restricted activity, which are also included in the generic concept of ‘‘restricted activity,’’ are shown both separately and as included in restricted activity days in this report. A person may restrict activities on a given day as a result of more than one condition, and these conditions may be acute or chronic. ‘‘Restricted activity associated with acute conditions’’ includes days on which one or more acute conditions caused the activity restriction. It also includes days on which one or more acute conditions and one or more chronic conditions caused the activity restriction. Because the restriction in activity was the result of both acute and chronic conditions, the cause cannot be attributed solely to an acute condition. Therefore, the term ‘‘associated with’’ rather than ‘‘caused by’’ is used to describe restricted activity. Incidence rates of restricted activity associated with acute conditions by type of condition and sociodemographic characteristics are shown in tables 16–20 , and incidence (number) is shown in tables 21–25 . The 1996 rates of restricted activity days (624.0) and bed-disability days (271.7) per 100 persons per year were not significantly Series 10, No. 200 [ Page 3

## different from the rates observed in 1995 (674.6 and 281.2, respectively). The rates of work-loss days for currently employed persons 18 years of age and over (284.0) and school-loss days for youths 5–17 years of age (296.9) were similar to the corresponding rates for 1995 (284.5 and 323.2, respectively). Detailed rates and frequencies for bed days, work-loss days, and school-loss days are shown in tables 26–49
. 

# Incidence by Quarter The 1996 incidence rate and incidence of acute conditions by quarter are shown in table 50 . The estimated rate for the first quarter of 1996 (51.4) was significantly lower than the corresponding rate for 1995 (57.2). In previous years, a significant difference in the first quarter rates between the current year and prior years was primarily due to changes in influenza rates. In 1996, the difference appears to be related to the lower rates of overall respiratory conditions and selected other acute conditions. The rate for the third quarter of 1996 (28.5) was significantly different from the rate observed in 1995 (32.8) and appears to be primarily due to less influenza in this quarter of 1996. 

# Episodes of Persons Injured Injury data may be analyzed in three ways: (a) the total number of injuries sustained during episodes involving injury, (b) the number of episodes involving injury during a given period of time, or (c) the number of persons involved in one or more episodes in which injury occurred during a period of time. The estimated number of injuries (measure (a) above) that occurred during 1996 is shown in tables 1–50
. Tables 51 and 52 present the number of episodes that occurred during 1996 that involved one or more injuries (measure (b) above). Because of the short reference period used to collect injury data in NHIS (2 weeks), the number of persons involved in one or more episodes during any given year (measure (c) above) cannot be accurately estimated. Table 51 shows the incidence rate of episodes of persons injured, and table 52 shows the incidence of such episodes by sociodemographic characteristics, by whether a moving motor vehicle was involved, and if so, by whether this occurred in traffic. The tables also show episodes classified by where the episode occurred and, for persons 18 years of age and over, by whether they were at work when the episode occurred. The 1996 rate of episodes of persons injured per 100 persons per year was 20.5. 

# Restricted Activity Associated with Injury and Impairment Due to Injury An injury may have health-related effects for many years after its occurrence or even for a lifetime (for example, a person who suffered a dislocated back due to an accident). The estimates of activity restriction (tables 53–54) and of bed days (tables 55–56) are based on the current effects of injuries regardless of when they occurred. Thus, these estimates include the days shown in earlier tables for acute injuries and also include days of restricted activity during 1996 that are attributable to the effects of injuries suffered prior to 1996. In many cases, these old injuries have become impairments, and any restricted activity during 1996 that was caused by an injury-related impairment is also included. The 1996 rate for restricted activity days associated with episodes of persons injured (226.4 per 100 persons per year) was lower than the comparable rate for 1995 (254.8). The 1996 rate for bed days associated with episodes of persons injured was 71.8 per 100 persons per year. 

# Prevalence of Reported Chronic Conditions Chronic conditions are defined as conditions that either (a) were first noticed 3 months or more before the reference date of the interview, or (b) belong to a group of conditions (including heart disease and diabetes) that are considered chronic regardless of when they began. To estimate the prevalence of reported chronic conditions, the NHIS sample is divided into six representative subsamples. Respondents in each subsample are administered one of six checklists of types of chronic conditions. Respondents are asked to indicate the presence or absence of each condition specified on the particular list assigned to them. Because the presence or absence of many types of chronic conditions is often difficult to ascertain, several ‘‘impact’’ questions are asked about each condition reported. Information is elicited on whether the person has been hospitalized for the condition and the number of days he or she stayed in bed because of the condition during the 12 months prior to the interview. Totals for all chronic conditions are not shown because NHIS only measures the prevalence of selected chronic conditions for each person. Because a person may have more than one chronic condition, the sum of counts of conditions may exceed the sum of persons having those conditions. Prevalence rates for selected chronic conditions are shown in tables 57–61 , and the prevalence (number) is shown in tables 62–66 . As shown in table 57 , the reported conditions with the highest prevalence rates were arthritis, sinusitis, deformity or orthopedic impairment, hypertension, hay fever or allergic rhinitis without asthma, hearing impairment, and heart disease (with rates per 1,000 persons of 127.3, 125.5, 111.6, 107.1, 89.8, 83.4, and 78.2, respectively). 

# Limitation of Activity Due to Chronic Conditions Limitation of activity refers to long-term reduction in activity resulting from chronic disease or impairment. The NHIS measurement of limitation of activity permits one to distinguish among (a) persons unable to carry on their usual activity, (b) persons limited in the amount or kind of their usual activity, (c) persons limited but not in their usual activity, and (d) persons not limited. The category of persons limited Page 4 [ Series 10, No. 200

## in their major activity includes those in the first two groups; that is, those unable to carry on usual activities for their age group, whether it is working, keeping house, going to school, or living independently, and those restricted in the amount or kind of usual activity for their age group. Persons limited, but not in their major activity, include persons restricted in other activities such as civic, church, or recreational activities. The 1996 estimate of the percent of persons limited in activity due to chronic conditions is 14.4% , and the estimate of persons limited in their major activity (categories (a) and (b) in the previous paragraph) is 10.0% . The percent distribution and frequencies for degree of activity limitation are shown by sociodemographic characteristics in tables 67–68
. 

# Restricted Activity Due to Acute and Chronic Conditions Earlier, estimates of restricted activity days associated with acute conditions (tables 16–49 ) and the relationship between the types of restricted activity days were discussed. The estimates shown in table 69 are for person days of restricted activity resulting from all conditions, either acute, chronic, or both. The 1996 estimated days of restricted activity per person per year were as follows: 14.5 days for all types of restricted activity, 5.9 days of bed disability, 4.8 days lost from work for currently employed persons, and 4.0 days lost from school for youths 5–17 years of age. The estimates for each type of restricted activity day are shown by sociodemographic characteristics in table 69
. 

# Respondent-Assessed Health Status Health Status Data on assessed health status are obtained by asking respondents to assess their own health or that of family members living in the same household as excellent, very good, good, fair, or poor. The percent distribution of health status for these categories, according to sociodemographic characteristics, is shown in table 70 . The health of most persons in the 1996 civilian noninstitutionalized population was assessed as ‘‘excellent’’ (37.4%) or ‘‘very good’’ (29.5%). Only 2.6% were assessed as ‘‘poor.’’ 

# Physician Contacts: Rate and Interval Since Last Contact A contact is defined as a consultation with a physician, in person or by telephone, for examination, diagnosis, treatment, or advice. The visit is considered a physician contact if the service is provided by the physician or by another person working under the physician’s supervision. 

# Annual Rate As shown in table 71 , the rate of physician contacts reported for 1996 was 5.9 doctor visits per person per year. In addition to sociodemographic characteristics, the rates and frequencies also are shown by the place of contact. The rate was highest for doctor’s office (3.2 per person per year) and was less than one contact per person per year via telephone and hospital, while the rate for ‘‘other’’ place was about one contact per person per year. 

# Interval Since Last Contact The percent distribution and frequency distribution of time intervals since the person last had a physician contact are shown in table 72 . Whereas the estimates for the rate of physician contacts do not include contacts while a person was an overnight patient in a hospital, such contacts are included in the definition of the interval since a person last saw or talked to a physician or a physician’s assistant. During 1996, an estimated 79.8% of the civilian noninstitutionalized population had contact with a physician during the year preceding the interview. Other estimates of ambulatory medical care services by physicians are provided by data from the National Ambulatory Medical Care Survey, a probability sample survey conducted periodically by the Division of Health Care Statistics of the National Center for Health Statistics. A summary of 1996 survey results is in Advance Data from vital and health statistics, No. 295 (17). 

# Hospitalization: Episodes and Days for Persons; Discharges and Average Length of Stay The NHIS respondents are asked to describe any hospitalizations that involved at least a one-night stay during the year preceding the interview. Two measures obtained through this series of questions are the number of times and the number of days spent in short-stay hospitals in the 12 months prior to the interview. Because persons who died or were institutionalized in a given reference period are not included in NHIS, the rates and frequencies shown in this report will vary from those based on surveys that get information on all overnight patients who entered a short-stay hospital during any given period of time. The difference will be greater for older persons. Estimates of hospitalizations are presented for episodes and for discharges. Episode estimates focus on the person’s hospital experience during the 12 months preceding the interview. The tables showing these estimates classify people on the basis of whether they were hospitalized during the reference period and, if so, the number of times they were hospitalized. Discharge estimates focus on hospital stays as the unit of analysis rather than on persons. 

# Hospital Episodes and Days The percent distributions of number of short-stay hospital episodes (first including and then excluding deliveries) during the year preceding the interview and according to sociodemographic characteristics are shown in table 73 , and the corresponding frequencies are shown in table 74 . The category ‘‘delivery’’ is based on the reason the woman entered the hospital or whether Series 10, No. 200 [ Page 5

## surgery related to delivery was performed. The rate of persons in 1996 with one hospital episode or more during the year preceding the interview was 7.3% , which was 29% lower than the 1982 estimate of 10.3% (1). The total number of days the person spent as a patient in the hospital is associated with the number of times a person was in a short-stay hospital during the year preceding the interview. In 1996, persons with one hospitalization or more spent an average of 6.8 days in the hospital in the year preceding the interview. Estimated rates and numbers of hospital days by the number of times people were hospitalized (including and excluding deliveries) and by sociodemographic characteristics are shown in tables 75 and 76
. 

# Hospital Discharges and Average Length of Stay Rates and numbers of hospital discharges, the average length of stay, and the number of hospital discharge days by sociodemographic characteristics and by whether a delivery was involved in the hospitalization are shown in table 77 . Based on data collected during 1996, there were 10.1 discharges per 100 persons, and the average length of stay per discharge was 5.3 days. Examining longer-term trends, the 1996 hospital discharge rate of 10.1 per 100 persons was about 29% lower than the rate estimated by the NHIS in 1981 (14.2), and the average length of stay, 5.3 days, was about 28% lower than in 1981 (7.4) (18). This trend probably reflects the following two phenomena: (a) some medical procedures, once performed as inpatient hospital care, are now performed in outpatient medical facilities, and (b) the Health Care Financing Administration (which operates the Medicare program), some States, and some third-party payers now reimburse hospitals for inpatient care using a pre-established payment schedule based on patients’ diagnosis-related groups. Information also is collected on hospital discharges from hospital records through the National Hospital Discharge Survey (NHDS) conducted by the National Center for Health Statistics. Estimates from NHDS, published in Advance Data or Series 13 publications of Vital and Health Statistics , are somewhat higher than those presented here because of differences in collection procedures, population sampled, and definitions used. In recent years, NHDS has experienced a decline in its hospital discharge rates, and the NHDS estimates of average length of stay for all persons also have declined. Thus, the trend data from the two surveys are consistent. The most recent national estimates of short-stay hospitalization based on NHDS are summarized in Vital and Health Statistics , Series 13, No. 140 (19). 

# Trends in Selected Health Measures, 1982–96 From 1982 through 1996, the main features of the National Health Interview Survey were unchanged. With some minor exceptions, there were no changes in the basic health and demographic questionnaire (the ‘‘Core’’ questionnaire), the fieldwork procedures, or the data processing system. Over that period the same organizations were responsible for data collection (U. S. Bureau of the Census) and survey design, data processing, and data analysis (NCHS). For each year during 1982–96, an annual statistical report was published, Current Estimates From the National Health Interview Survey (1, 2, 4–15), with a standardized set of detailed tables. Changes in data systems often cause changes in the estimates of statistics they produce, even when that is neither intended nor desired. Such changes occurred when a revised NHIS questionnaire was introduced in 1982 (1), and such changes are expected in the 1997 estimates as a result of a questionnaire redesign and introduction of computer-assisted personal interviewing. Such changes in data systems introduce spurious fluctuations in statistical trends, confounding their interpretation. The stability of the NHIS data system from 1982 to 1996 largely removes those confounding factors, increasing confidence that statistical trends indicate real change (or lack thereof) in the factors they are intended to measure. Taking advantage of the opportunity for trend analysis in the 1982–96 NHIS, this section highlights some of those trends. The data for trends considered come from standard tables published in Current Estimates From the National Health Interview Survey for the years 1982–96 (1, 2, 4–15). The standard tables for Current Estimates, 1982–96, covered two broad areas, health status and utilization of health services. Health status measures included acute conditions, injuries, restricted activity resulting from acute conditions and injuries, chronic conditions, activity limitation resulting from chronic conditions, and respondent-assessed general health. Utilization of health services included physical contacts and hospitalization. The trends described and discussed here were selected to represent most of those areas and because of their intrinsic interest. 

# Acute Conditions Figure 1 shows trends in the number of acute conditions per 100 persons for calendar quarters from 1982 through 1996, as published in Current Estimates for those years (1, 2, 4–15). The seasonal pattern in acute conditions is very apparent: the incidence of acute conditions is highest in the first quarter of each year (January–March), lower in the second quarter (April–June), usually lowest in the third quarter (July–September), and then rises in the last quarter (October–December), reaching a new peak in the first quarter of the next year. The seasonal pattern was very stable: the ‘‘waves’’ of illness varied little in their frequency or amplitude, and there is no overall trend apparent over the 15-year period. Figure 2 shows trends in the leading types of acute conditions from 1982 through 1996. There was no overall trend in any of these conditions and Page 6 [ Series 10, No. 200

## little year-to-year variation, except for influenza. Influenza shows peaks and valleys over 2- or 3-year periods that correspond to influenza outbreaks. During 1982–96, the NHIS definition required that an acute condition be serious enough to have had at least one of several impacts on personal behavior, including contacting a physician, staying in bed, staying home from school, staying home from work, or cutting down on normal activities. Figure 3 shows trends in the number of bed days, school-loss days, and work-loss days per 100 persons per year during 1982–96. While there was no long-term trend in restricted activity days associated with acute conditions, there were several cycles lasting 2 or 3 years, most visibly in school-loss days. The peaks in the cycles of restricted activity days correspond to (and were caused by) the outbreaks of influenza previously observed. 

# Chronic Conditions During 1982–96, the NHIS interviewers read a list of specific chronic conditions and impairments to respondents and asked if any family member had any of the conditions. If a condition was reported, additional questions were asked to determine more precisely the category of the disease entity in the International Classification of Diseases (16). The procedure was intended to obtain as nearly complete reporting of chronic conditions and impairments as possible within the constraints of a household interview. Because it would have been too burdensome on respondents to ask about all of the conditions on the complete list of 134 conditions, the list was divided into six sublists, each organized around a body system, and one list was chosen at random to be read in each household. These procedures had the benefit of producing estimates of the prevalence of many different conditions every year, but at the cost of basing those estimates on only one-sixth of the sample, which made the estimates less reliable statistically. Figure 4 illustrates trends in the prevalence of chronic conditions, focusing on three conditions from the list of respiratory conditions: chronic bronchitis, asthma, and emphysema. Because chronic conditions are by definition long-lasting, year-to-year changes in prevalence are unlikely to be very large. When the prevalence estimates do change over a one-year period, as for instance in the increase in asthma in 1987, the most probable explanation is sampling error— as just noted, these estimates are based on one-sixth subsamples in each year, and therefore have fairly large sampling errors. The low level of bronchitis for 1982 may have another explanation: that Figure 3. Trends in restricted activity days: United States, 1982–96 Page 8 [ Series 10, No. 200

## was the first year in which the new questionnaire was introduced, and there were the usual start up problems encountered by any complex new data system. Those caveats aside, there is one apparent trend revealed in figure 4 : the upward trend in the reported prevalence of asthma, from levels below 40 per 1,000 persons per year in the early 1980’s to levels above 50 per 1,000 in the mid-1990’s. This trend has been noted by other data systems in the United States (20), and there has been considerable research on its possible causes, with no consensus yet having been achieved. There also was an apparent increase in the prevalence of chronic bronchitis, from below 40 per 1,000 in 1982 to over 50 per 1,000 in 1996; however, most of that increase occurred between 1982 and 1983, and may reflect some anomaly in the data for 1982, the first year of the redesigned survey. 

# Health Care Utilization The 1982–96 Current Estimates (1, 2, 4–15) reported standard tables on two types of health care: physician contacts and hospitalization. Figure 5 illustrates those data with trends in the percent of persons who were hospitalized one or more times in the year before interview, and the average number of days spent in the hospital during the year. This period in history saw the introduction of various innovations in health care financing and health care delivery that were intended to contain the escalating cost of health care. Because the high cost of hospital care was a major factor in rising costs, many of the innovations were intended to reduce the number and duration of hospital stays. The effects of those efforts are evident in figure 5 : the percent of persons hospitalized declined from over 10% to just over 7%, and the average number of days spent in the hospital (by those who were hospitalized at all) declined from about 9 days to about 7 days per year.

Category not applicable. *Figure does not meet standard of reliability or precision. 1 Sum of school-loss days for children 5–17 years of age and work-loss days for currently employed persons 18 years of age and over. School-loss days are s hown for the age group 5–17 years; work-loss days are shown for the age group 18 years and over and each older age group. 2 Includes other races and unknown family income. 3 MSA is metropolitan statistical area. NOTES: The standard errors (SE’s) and relative standard errors (RSE’s) for age, sex and age, and race and age for columns 1 and 2 can be computed by using p arameter set II of table II, the frequencies of table 69 and the formula presented in rule 2 of appendix I. The SE’s and RSE’s for family income and age, geographic region, and place of re sidence for columns 1 and 2 can be computed by using parameter sets II and X of table II, the frequencies of tables 69 and 78, and the formula presented in rule 4 of appendix I. The SE’s and RS E’s for column 3 (work-loss) can be computed by using parameter sets III and X of table II, the frequencies of tables 69 and 78, and the formula presented in rule 4 of appendix I. The SE’s and R SE’s for age, sex and age, and race and age for column 3 (school-loss) can be computed by using parameter set III of table II, the frequencies of table 69, and the formula presented in rule 2 of a ppendix I. The SE’s and RSE’s for family income and age, geographic region, and place of residence for column 3 (school-loss) can be computed by using parameter sets III and X of table II, the frequencies of tables 69 and 78, and the formula presented in rule 4 of appendix I. The SE’s and RSE’s for columns 4 and 5 can be computed by using parameter set II of table II and the formula presen ted in rule 1 of appendix I. The SE’s and RSE’s for column 6 can be computed by using parameter set III of table II and the formula presented in rule 1 of appendix I. For restricted-activity an d bed-days, an estimate of 116.9 million has an RSE of 10 percent; 27.6 million, of 20 percent; and 12.2 million, of 30 percent. For work- or school-loss days, an estimate of 81.6 million has an RSE of 10 percent; 20.2 million, of 20 percent; and 9.0 million, of 30 percent.

NOTES: The standard errors (SE’s) and relative standard errors (RSE’s) for family income and age, geographic region, and place of residence for colum n 1 can be computed by using parameter set X of table II and the formula presented in rule 1 appendix I. The SE’s and RSE’s for age, sex and age, and race and age for columns 3–7 can be computed by using p arameter set X of table II, the frequencies of table 70, and the formula presented in rule 2 of appendix I. The SE’s and RSE’s for family income and age, geographic region, and place of residence for columns 3–7 can be computed by using parameter set X of table II, the frequencies of table 70, and the formula presented in rule 3 of appendix I. An estimate of 669,000 has a 10-percen t RSE; of 167,000, a 20-percent RSE; and of 74,000, a 30-percent RSE.

NOTES: The standard errors (SE’s) and relative standard errors (RSE’s) for age, sex and age, and race and age for columns 1 and 5 can be computed by using p arameter set VIII of table II, the frequencies of table 77 and the formula presented in rule 2 of appendix I. The SE’s and RSE’s for family income and age, geographic region, and place of re sidence for columns 1 and 5 can be computed by using parameter sets VIII and X of table II, the frequencies of tables 77 and 78, and the formula presented in rule 4 of appendix I. The SE’s and RSE’s for columns 2 and 6 can be computed by using parameter set VIII of table II and the formula presented in rule 1 of appendix I. The SE’s and RSE’s for columns 4 and 8 can be computed by u sing parameter set IX of table II and the formula presented in rule 1 of appendix I. The SE’s and RSE’s for columns 3 and 7 can be computed by using parameter sets VIII and IX of table II, the freq uencies of table 77, and the formula presented in rule 4 of appendix I. An estimate of 1.4 million discharges has a 10-percent RSE; of 332,000, a 20-percent RSE; and of 147,000, a 30-percent RSE. An estimate of 48.5 million days has a 10-percent RSE; of 4.6 million, a 20-percent RSE; and of 1.8 million, a 30-percent RSE.

# Appendix I Technical Notes on Methods Background This report is one of a series of statistical reports published by the staff of the National Center for Health Statistics (NCHS). It is based on information collected in a continuing nationwide sample of households included in the National Health Interview Survey (NHIS). Data are obtained on the personal, sociodemographic, and health characteristics of family members and unrelated individuals living in these households. Field operations for the survey are conducted by the U.S. Bureau of the Census under specifications established by NCHS. The U.S. Bureau of the Census participates in the survey planning, selects the sample, and conducts the interviews. The data are then transmitted to NCHS for preparation, processing, and analysis. Summary reports and reports on special topics for each year’s data are prepared by the staff of the Division of Health Interview Statistics for publication in Series 10 publications. Data are also tabulated for other reports published by NCHS staff and for use by other organizations and by researchers inside and outside the Government. Since 1969, public use tapes have been prepared for each year of data collection. Public use microdata also are available on compact disk read-only memory (CD-ROM) for 1987–96 and will be available for subsequent survey years in the future. It should be noted that the health characteristics described by NHIS estimates pertain only to the resident, civilian noninstitutionalized population of the United States living at the time of the interview. The sample does not include persons residing in nursing homes, members of the armed forces, institutionalized persons, or U.S. nationals living abroad. 

# Statistical Design of the NHIS General Design Data from NHIS have been collected continuously since 1957. The sample design of the survey has undergone changes following each decennial census. This periodic redesign of the NHIS sample allows the incorporation of the latest population information and statistical methodology into the survey design. The data presented in this report are from the NHIS sample design first used in 1995. This design will be used through 2004. The sample design plan of NHIS follows a stratified, multistage probability design that permits a continuous sampling of the civilian noninstitutionalized population residing in the United States. The NHIS is designed to produce more reliable estimates for the black population and the Hispanic population than a national household survey of the same size in which all households have the same probability of sample selection. The survey is designed so that the sample scheduled for each week is representative of the target population, and the weekly samples are additive over time. This design permits reliable estimates for high-frequency measures or for large population groups to be produced from a short period of data collection. Reliable estimates for low-frequency measures or for smaller population subgroups can be obtained from a longer period of data collection. The annual sample is designed so that tabulations can be provided for each of the four major geographic regions. Because interviewing is done throughout the year, there is no seasonal bias for annual estimates. The continuous data collection also has administrative and operational advantages because fieldwork can be handled on a continuing basis with an experienced, stable staff. Sample Selection The target population for NHIS is the civilian noninstitutionalized population residing in the United States. For the first stage of the sample design, the United States is partitioned into approximately 1,900 geographically defined primary sampling units (PSU’s). A PSU consists of a county, a small group of contiguous counties, or a metropolitan statistical area. The PSU’s collectively cover the 50 States and the District of Columbia. First, the individual PSU’s for the 52 largest metropolitan areas are defined to be self-representing strata. Within each State, the remaining PSU’s are combined into strata. As part of this process, an additional 43 PSU’s are also designated as self-representing strata. Thus, the NHIS sample has a total of 95 self-representing PSU’s. The other PSU’s in the universe are referred to as nonself-representing PSU’s. NHIS PSU’s are clustered into a total of 237 strata: 95 strata are self-representing and 142 strata are nonself-representing. In 121 of the nonself-representing strata, 2 PSU’s were selected for the NHIS sample. In the remaining 21 nonself-representing strata, 1 was selected for the NHIS sample, usually because the stratum was relatively small in population size. Thus, the NHIS sample encompasses 358 PSU’s. Within a PSU, two types of second stage units (called segments) are used: area segments and permit area segments. Area segments are defined geographically and contain an expected 8 or 12 households. Permit area segments cover geographical areas containing housing units built after the 1990 census. The permit area segments are defined using updated lists of building permits issued in the PSU since 1990 and contain an expected four households. NHIS accomplishes its objective to produce more reliable estimates for black and Hispanic people by oversampling. Segments located in areas with higher concentrations of black or Hispanic people are sampled at a higher rate. Furthermore, within a segment, all households with a black or Hispanic person are retained in the sample, while a probability subsample of the other households is retained. Occasionally, a sample segment may contain a substantially larger number of households than expected. In this situation, all households are subsampled Series 10, No. 200 [ Page 129

## to provide a manageable interviewer workload. The sample was designed so that a typical NHIS sample for the data collection years 1995–2004 will consist of approximately 7,000 segments containing about 70,000 addresses. Of these households, about 20% will be vacant, demolished, or occupied by persons not in the target population of the survey. After the screening for race and ethnicity and subsampling, a 52-week NHIS expected sample of 43,000 occupied households will yield a probability sample of about 111,000 persons. In 1996, NHIS was in the field for 50 weeks. Two weeks in 1996 were used for interviewer training. Also, part of the 1996 NHIS sample was used for testing the computer-assisted personal interview (CAPI) system that was implemented for the 1997 NHIS. The CAPI test cases were not included in the 1996 NHIS data set used to produce the estimates in this report. Relative to 1995, the 1996 NHIS sample size is reduced by approximately 25% in the first and second quarters, and by approximately 50% in the third and fourth quarters. The interviewed sample for 1996 consisted of 24,371 households containing 63,402 persons. Features of the NHIS Sample Redesign Starting in 1995, the NHIS design incorporated several new design features (3). The primary features in the 1990 NHIS sample design implemented in January 1995 included the following: 1. Use of an all-area sampling frame. NHIS is based on an all-area sampling frame. This is in contrast to the decennial census address sampling frame used by other current surveys conducted by the U.S. Bureau of the Census (including the Current Population Survey, the National Crime Victimization Survey, and the Survey of Income and Program Participation). The use of an all-area frame sample permits NCHS to obtain the addresses in the NHIS sample. This address information is confidential and only used by NCHS contractors and collaborators for additional data collection. NHIS has been based on an all-area sampling frame since 1985. 2. NHIS has four panels. Four national subdesigns, or panels, constitute the full NHIS. Each panel contains a representative sample of the U.S. civilian noninstitutionalized population. Each of the four panels has the same sampling properties, and any combination of panels defines a national design. Panels were constructed to facilitate the linkage of NHIS to other surveys and also to efficiently make large reductions in the size of the sample by eliminating panels from the survey. 3. Oversampling of black and Hispanic persons. The NHIS sample design implemented in 1995 oversamples black and Hispanic persons. This was accomplished with two features. First, segments were selected at higher rates in areas with higher concentrations of black and Hispanic persons. Second, within a segment, a larger initial address sample than would otherwise be required was taken. In this larger sample, all households with a black or Hispanic person were retained in the survey; only a subsample of the other households was retained. The determination of a household’s race-ethnicity status was accomplished through the administration of a brief interview. 4. State stratification and increase in the number of primary sampling units (PSU’s). With few exceptions, the NHIS first-stage sampling strata do not straddle state boundaries. The exception occurs for some of the largest metropolitan areas that are self-representing PSU’s and straddle State boundaries. For example, the New York-Northern New Jersey-Long Island NY-NJ-CT-PA Consolidated Metropolitan Area straddles four States. In these cases, NHIS second-stage samples were drawn independently within each State component of the PSU. This State stratification, taken together with a near doubling of the number of PSU’s in the NHIS sample (over the 1985–94 NHIS), will facilitate the use of NHIS in a dual frame sample. The largest increase in the number of sample PSU’s occurs in those representing nonmetropolitan areas. To maintain a sample size similar to the previous year, the average number of sampled households assigned to such PSU’s was reduced. Of the 25,990 households eligible for interview in 1996, 24,371 households were actually interviewed, resulting in a sample of 63,402 persons. 

# Collection and Processing of Data The NHIS questionnaire contains two major parts. The first part consists of topics that remain relatively the same from year to year. Among these topics are the incidence of acute conditions, the prevalence of chronic conditions, persons limited in activity due to chronic conditions, restriction in activity due to impairment or health problems, and utilization of health care services involving physician care and short-stay hospitalization. Occasionally, new questions are incorporated into the main questionnaire. Since 1985, questions that ask the household member’s city and State of birth, social security number, and father’s last name have been included. In 1989, questions were added that ask the location (city, county, and State) of any physician contact, whether by telephone or in person. In that year, questions were also added that ask household members born in the United States how many years they have lived in the State of residence, and ask household members born in a foreign country how many years they have lived in the United States. In 1992, a question was added for persons 12–21 years of age, asking whether they were either now going to school or on vacation from school. Although this question was retained in 1993, no data were collected and the question was deleted in 1994. In 1992, race was expanded into 15 detailed racial groupings and included an ‘‘other race’’ category. In 1994, this Page 130 [ Series 10, No. 200

## question was moved within section L from question 3 to question 4. In 1992, the Hispanic origin questions were moved from section L (questions 4a and 4b) to section A (questions 4e and 4f), and in 1994 they were returned to section L (questions 3a and 3b). In 1992, questions were added that asked about the Hispanic oversample’s reference person or family member’s status of previous year’s residence (section A, questions 4g and 4h). Although these questions were retained in 1993, there was no Hispanic oversampling and no data were collected for these questions. They were deleted in 1994. In 1993, the NHIS added E-coding (Supplementary Classification of External Causes of Injury and Poisoning) for injuries including medical and therapeutic misadventures. Beginning in 1994, a question was added asking if there was a working telephone in the home. In 1995, the following changes also were made to the main questionnaire: the cover page of the questionnaire contains several revisions related to the necessary requirements of the sample redesign and methodology; the introduction and hospital probe questions were moved from section A (questions 5–7b) to immediately follow section A; the Hispanic origin questions were moved from section L (questions 3a and 3b) to section A (questions 5a and 5b); the questions on race were moved from section L (questions 4a–4c) to section A (questions 6a–6c) (these two items were inserted into the questionnaire earlier than previously to assist in oversampling black and Hispanic persons through household screening); and two questions were added to the end of section L (questions 17–18) that ask if the household had been without telephone service for more than 1 week during the past 12 months and for how long the household had been without telephone service in the past 12 months. In 1996, no significant changes were made to the main questionnaire. Because of the smaller sample size used in 1996, special health topics were kept to a minimum. The second part of NHIS consists of special topics added as supplements to each year’s questionnaire. The supplemental questionnaires included in 1996 are shown in appendix III. Tables 51–56 of Current Estimates reports for 1982–94 contained an overestimate of reported episodes of injury and associated days. Only estimates of the number of episodes and days associated with injury were affected, not the number of injuries. For example, in some cases, if a single incident (‘‘an episode’’) involving a fall resulted in multiple injuries such as a broken arm, a sprained ankle, and a cut on the head, it was incorrectly counted as three episodes involving injury rather than one episode of injury involving multiple injuries. The breadth of the resultant overestimates was generally small, but would be larger for types of episodes that frequently caused multiple injuries such as falls and incidents involving motor vehicles. NHIS strives to minimize such errors for data quality and accuracy by careful scrutiny and other quality control measures. Sometimes, regrettably, minor errors do occur. This information has been corrected on NHIS data files, and corrected Current Estimates tables are available upon request from DHIS. Careful procedures are followed so that quality data are collected in the interview. Most households in the sample are contacted by mail before the interviewers arrive. Potential respondents are informed of the importance of the survey and assured that all information obtained in the interview will be held in strict confidence. Interviewers make repeated trips to a household when a respondent is not immediately found. The success of these procedures is indicated by the response rate for the survey, which has been between 93% and 96% over the years. When contact is made, the interviewer attempts to have all family members of the household 19 years of age and over present during the interview. When this is not possible, proxy responses for absent adult family members are accepted. In most situations, proxy respondents are used for persons under 19 years of age. However, persons 17–18 years of age may respond for themselves. Interviewers undergo extensive training and retraining. The quality of their work is checked by periodic observation and by reinterview. Their work is also evaluated by statistical studies of the data they obtain in their interviews. A field edit is performed on all completed interviews so that if there are any problems with the information on the questionnaire, respondents may be recontacted to solve the problem. Completed questionnaires are sent from the U.S. Bureau of the Census field offices to NCHS for coding and editing. To ensure the accuracy of coding, a 5% sample of all questionnaires is recoded and keyed by other coders. A 100% verification procedure is used if certain error tolerances are exceeded. Staff of the Division of Health Interview Statistics then edit the files to remove impossible and inconsistent codes. Several variables (age, month of birth, and Hispanic origin) in the final 1996 NHIS data set include a small proportion of imputed values that fill in for missing values. The interview, fieldwork, and data processing procedures summarized above are described in detail in Series 1, No. 18 (24). 

# Estimation Procedures Because the design of NHIS is a complex multistage probability sample (25), it is necessary to reflect these complex procedures in the derivation of estimates (3). The estimates presented in this report are based upon 1996 sample person counts weighted to produce national estimates. The weight for each sample person is the product of four component weights: 1. Probability of selection. The basic weight for each person is obtained by multiplying the reciprocals of the probabilities of selection at each step in the design: PSU, segment, and household. For 1996, an additional factor is included to account for the use of part of the 1996 NHIS sample for CAPI testing. 2. Household nonresponse adjustment within segment. In NHIS, interviews are completed in about 94% of all Series 10, No. 200 [ Page 131

## eligible households. Because of household nonresponse, a weighting adjustment is required. The screening of black and Hispanic households and the subsampling of all other households result in the nonresponse adjustment taking a somewhat more complicated form than that for the previous NHIS. The nonresponse adjustment weight is a ratio of the within-segment weighted number of sample households to the within-segment weighted number of actually interviewed households, both numbers exclusive of households with unknown black/Hispanic status. For segments with nonresponding households of unknown black/Hispanic status, the previously mentioned factor was multiplied by the ratio of the number of segment households to the number of known status households. This adjustment reduces bias in an estimate to the extent that persons in the noninterviewed households have the same characteristics as the persons in the interviewed households in the same segment. 3. First-stage ratio adjustment. The weight for persons in the nonself-representing PSU’s is ratio adjusted to the 1990 population within six race-ethnicity-residence classes of the nonself-representing strata within each geographic region. 4. Poststratification by age-sex-raceethnicity. Within each of 88 age-sex-race-ethnicity cells (table I), a weight is constructed each quarter to ratio adjust the first-stage population estimate based on the NHIS to an independent estimate of the population of each cell. These independent estimates are prepared by the U.S. Bureau of the Census and are updated quarterly. Beginning in 1994, the independent estimates include an adjustment for estimated net underenumeration in the 1990 Decennial Census. The main effect of the ratio-estimating process is to make the sample more closely representative of the target population by age, sex, race-ethnicity, and residence. The poststratification adjustment helps to reduce the component of bias resulting from sampling frame undercoverage. Furthermore, this adjustment frequently reduces sampling variance. 

# Types of Estimates As noted, the NHIS data were collected on a weekly basis, with each week’s sample representing the resident, civilian noninstitutionalized population of the United States living during that week. The weekly samples are consolidated to produce quarterly files (each consisting of data for 13 weeks). Weights to adjust the data to represent the U.S. population are assigned to each of the four quarterly files. These quarterly files are later consolidated to produce the annual file, which is the basis of most tabulations of the NHIS data. NHIS uses various reference periods to reduce the amount of bias associated with respondent memory loss. A 2-week reference period is used in collecting data on the incidence of acute conditions, restriction in activity due to a health problem, and physician contacts. Each of these measures health events that may be forgotten soon after they occur. Examples of such events are telephoning a physician about a minor illness, missing a day from work because of a routine health problem, or having a cold. Either a 12- or 6-month (depending on the type of statistic) reference period is used for hospitalization data because hospitalization ordinarily involves a major event in a person’s life and is not quickly forgotten. Chronic condition prevalence estimates are based on a 12-month reference period. Because most NHIS estimates based on a 2-week reference period are designed to represent the number of health events for a 12-month period, these data must be adjusted to an annual basis. Event counts based on a 2-week reference period are multiplied by 6.5 to produce the 13-week estimate for the quarter. These reference period adjustments are made at the time that the quarterly files are produced. Therefore, the data can be used to produce estimates for each quarter and are used that way to study seasonal variation. The data from the four quarterly files (representing the number of events in each quarter) are summed to produce the annual estimate. Although these data are collected for only 2 weeks for each person included Table I. The 88 poststratification age-sex-race-ethnicity cells in the National Health Interview Survey, 1996

### Page 132 [ Series 10, No. 200

## in the survey, any unusual event that may have occurred during a particular 2-week period does not bias the estimate because the quarterly estimate is a sum of the estimates produced for each week’s sample during the entire quarter and the annual estimate is the sum of the four quarters. For prevalence statistics, such as the number of persons limited in activity due to chronic conditions, the annual estimate results from summing the weighted quarterly files and dividing by 4. This division is necessary because, as noted above, each quarterly file has been weighted to produce an estimate of the number of persons in the U.S. population with a given characteristic. Summing the four quarters and dividing by 4 in effect averages these quarterly results for the year. Thus, the type of prevalence estimate ordinarily derived from the NHIS data is an annual average prevalence estimate. For data related to short-stay hospital discharges that are based on a 6-month reference period, cases identified during any quarter of data collection are multiplied by 2 to produce a quarterly estimate of the annual number of characteristics associated with short-stay hospital discharges. The NHIS average annual estimate of hospital discharges is derived by summing the four quarterly estimates and dividing by 4, just as the prevalence estimates are. 

# Reliability of the Estimates Because the NHIS estimates are based on a sample, they may differ somewhat from the figures that would have been obtained if a complete census had been taken using the same survey and processing procedures. There are two types of errors possible in an estimate based on a sample survey: sampling and nonsampling errors. To the extent possible, these types of errors are kept to a minimum by methods built into the survey procedures described earlier (26). Although it is very difficult to measure the extent of bias in NHIS, several studies have been conducted to examine this problem. The results have been published in several reports (27–30). Nonsampling Errors Interviewing process—Information, such as the number of days of restricted activity caused by a condition, can be obtained more accurately from household members than from any other source because only the persons concerned are in a position to report this information. However, there are limitations to the accuracy of diagnostic and other information collected in household interviews. For example, for diagnostic information, the household respondent can usually pass on to the interviewer only the information the physician has given to the family. For conditions not medically attended, diagnostic information is often no more than a description of symptoms. Further, a respondent may not answer a question in the intended manner because he or she has not properly understood the question, has forgotten the event, does not know, or does not wish to divulge the answer. Regardless of the type of measure, all the NHIS data are estimates of health measures known to and willingly reported by the respondents. Reference period bias—The NHIS estimates do not represent a complete measure of any given topic during the specified calendar period because data are not collected in the interview for persons who died or became institutionalized during the reference period. For many types of statistics collected in the survey, the reference period is the 2 weeks prior to the interview week. For such a short period, the contribution by decedents to a total inventory of conditions or services should be very small. However, the contribution by decedents during a long reference period (such as 1 year) might be significant, especially for older persons. Underreporting associated with a long reference period is most germane to data on hospitalization. Analysis has shown that there is an increase in underreporting of hospitalizations with an increase in the time interval between the discharge and the interview. Exclusive of the hospital experience of decedents, the net underreporting using a 12-month recall period is in the neighborhood of 10% (31). The underreporting of discharges within 6 months of the week of interview is estimated to be about 5% (31). For this reason, hospital discharge data are based on hospital discharges reported to have occurred within 6 months of the week of interview. Because hospitalization is common in the period immediately preceding death or institutionalization and older persons are much more likely to die than younger ones, the data should not be used to estimate the volume of hospitalization of the elderly. However, the data can be used to measure characteristics of elderly people. It should further be noted that although the reported frequencies and rates related to hospital episodes are presented by the year in which the data were collected, the estimates are, in most cases, based on hospitalizations that occurred during the year of data collection and the prior year. Overall, approximately one-half of the reported hospitalizations for the 12-month reference period began in 1995. Population estimates—Some of the published tables include population figures for specified categories. Except for overall totals for the 88 age, sex, and race-ethnicity groups shown in table I , which are adjusted to independent estimates, these figures are based on the sample of households in NHIS. They are given primarily to provide denominators for rate computation, and for this purpose they are more appropriate for use with the accompanying measures of health characteristics than other population data that may be available. With the exception of the overall totals by age, sex, and race-ethnicity mentioned above, the population figures may differ from figures (which are derived from different sources) published in reports by the U.S. Bureau of the Census. Official population estimates are presented in U.S. Bureau of the Census reports in Series P-20, P-25, and P-60. Rounding of numbers—In published tables, the figures are rounded to the nearest thousand, although they are not necessarily accurate to that detail. Derived statistics, such as rates and percent distributions, are computed after the estimates on which these are based Series 10, No. 200 [ Page 133

## have been rounded to the nearest thousand. Combining data years—To reduce sampling error, data for number of years may be combined. However, in so doing, the questionnaire for each of the years should be checked, because even a small change in the questionnaire design may lead to large changes in the derived estimates. This caution also applies to using the NHIS data on health measures where changes in other events, such as legislative changes, have occurred over time. Sampling Errors The standard error is primarily a measure of sampling error, that is, the variation that might occur by chance because only a sample of the population is surveyed. The chances are about 68 in 100 that an estimate from the sample would differ from a complete census by less than the standard error. The chances are about 95 in 100 that the difference would be less than twice the standard error, and about 99 in 100 that it would be less than 21⁄2 times as large. Individual standard errors were not computed for each estimate in this report. Instead, standard errors were computed for a broad spectrum of estimates. Iterative least squares regression techniques were then applied to produce equations from which a standard error for any estimate can be approximated. The model (5.2.1) and fitting criterion (5.4.3) in chapter 5 of reference 32 were used. The regression equations, represented by parameters a and b, are presented in table II , along with the R2 

## for the regression fit. The value of R2 

## is in the interval . Roughly speaking, an R2 

## value close to 1 means that the regression equation provided a good standard error approximation, while an R2 

## value close to 0 means that the regression equation provided a poor approximation. Also shown are the cutoff values, i.e., the estimated number of persons or events below which the estimated relative standard error is greater than 30%; these estimates do not meet NHIS standards of statistical reliability. Rules explaining the use of the a and b parameters are presented below. The reader is cautioned that this procedure will give an approximate standard error of an estimate rather than the precise standard error. The reader is further cautioned that particular care should be exercised when the denominator is small. General Rules for Determining Standard Errors To produce approximate standard errors for the NHIS estimates, the reader must first determine the type of characteristic to be estimated, that is, the parameter set in table II to be used. The reader must then determine the type of estimate for which the standard error is needed. The type of estimate corresponds to one of five general rules for determining standard errors. Rule 1. Estimated number of people or events For the estimated number of people or events published in this report, there are two cases to consider. For the first case, if the estimated number is any combination of the poststratification age-sex-race-ethnicity cells in table I , then its value has been adjusted to officialU.S. Bureau of the Census figures and its standard error is assumed to be 0.0. This corresponds to parameter set XI in table II . As an example, this would be the case for the number of persons in the U.S. target population or the number of non-Hispanic black persons in the 18–34 year age group. Although the race-ethnicity class ‘‘white’’ is not specifically adjusted to U.S. Bureau of the Census figures, it dominates the poststratification ‘‘non-Hispanic other’’ race class; consequently, age-sex-‘‘non-Hispanic other’’ race combinations of table I can be treated as age-sex-white combinations for the purpose of approximating standard errors. For the second case, the standard errors for all other estimates of numbers of people or events, such as the number of people limited in activity or the number of acute conditions, are approximated by using the parameters provided in table II and formula 1 below. If the aggregate x for a characteristic has associated parameters a and b , then the approximate standard error for x, SE(x), can be computed by the formula SE( x) =

## Example of rule 1 . As shown in table 7 , the estimated number of acute conditions for males is 193,336,000. From table II , parameter set I, the a and b parameters for the numbers of acute conditions are 0.000418 and 157,000, respectively. Using formula 1, the estimated standard error is 

# √ (0.000418)(193,336,000) 2 

## + (157,000)(193,336,000)

= 6,780,715. An approximate 95% confidence interval for the number of acute conditions for males is [180,045,600, 206,626,400] (193,336,000 ± 1.96(6,780,715)). Examples are not provided for rules 2–5 or for approximating the relative standard error of an estimate. Readers are referred to appendix I of Current Estimates from the National Health Interview Survey, 1992 (12) for examples using the 1992 estimates. Rule 2. Rates, proportions, and percentswhen the denominator is generated by the poststratification agesex-race-ethnicity classes (table I ) In this case, the denominator has no sampling error. For example, rule 2 would apply to the estimated number of bed days per person for black persons age 65 years and over because the denominator is a combination of the poststratification cells. Approximate standard errors for such estimates can be computed using table II a and b parameters associated with the numerator characteristics, along with formula 2 below. If the estimate of rate, proportion, or percent p is the ratio of two estimated numbers, p = x/Y (where p may be inflated by 100 for percents or 1,000 for rates per 1,000 persons), with Y having no sampling error, then the approximate standard error for p is given by the formula SE( p) = p 

# √ a + b x (2) In this report, the value of the denominator Y is always provided, but in a few cases the numerator value x is not published. For these cases, the value of x may be computed by the formula Rule 3. Proportions and percents whenthe denominator is not generated by the poststratification agesex-race-ethnicity classes If p represents an estimated percent, b is the parameter from table II associated with the numerator characteristics, and y is the number of persons in the denominator upon which p is based, then the standard error of p may be approximated by
SE (p) = 

# Œ bp (100 – p) y (3) (If p is a proportion, then the above formula can be used, but with 100 replaced by 1.0.) Rule 4. Rates when the denominator isnot generated by the poststratification age-sex-race-ethnicity classes If the estimated rate p is expressed as the ratio of two estimates, i.e., p = x / y (inflated by 100 or 1,000 when appropriate), then the estimated standard error for p is given by the formula

SE( p) = p

No estimates of r, the correlation between the numerator and denominator, are presented in this report; therefore, only the first two terms are available. The reader must assume that r = 0.0, which will yield an overestimate of the standard error if r is actually positive and an underestimate if r is negative. Rule 5. Difference between two statistics(two means, rates, totals, or proportions) If x1

## and x2 

## . Assuming that r = 0.0 will result in an accurate standard error if the two estimates are actually uncorrelated and will result in an overestimate of the standard error if the correlation is positive or an underestimate if the correlation is negative. Relative Standard Errors Prior to 1985, relative standard error (RSE) curves were present in Current Estimates for approximating relative standard errors. For readers who wish to continue using them, the following provides guidance. The RSE of an estimate is obtained by dividing the standard error (SE) of the estimate by the estimate x itself. This quantity is expressed as a percent of the estimate: RSE = 100 SE( x) x 

# Appendix II Definitions of Certain Terms Used in This Report Terms Relating to Conditions Condition—Condition is a general term that includes any specific illness, injury, or impairment. Condition data are derived from the survey in two ways. First, respondents are asked to identify any conditions that caused certain types of impact associated with health, such as a visit to a doctor or a day spent in bed. Second, respondents x = 

# { pY if p is a proportion or rate per unit or pY 100 if p is a percent or rate per 100 units or pY 1,000 if p is a rate per 1,000 units Series 10, No. 200 [ Page 135

## are read lists of selected chronic conditions and asked whether they or any family members have any of these conditions. At a later point in the survey, a series of questions is asked about each of the conditions identified in either of the two ways just described. The information obtained on each condition helps to clarify the nature of the condition and whether medical services have been involved in its diagnosis or treatment. It also aids in the coding of the condition. All conditions except impairments are coded according to the Ninth Revision of the International Classification of Diseases (16), with certain modifications adopted to make the codes more suitable for information derived from a household survey. A special set of codes devised by the NHIS is used to code impairments. Chronic condition—A condition is considered chronic if (a) the respondent indicates it was first noticed more than 3 months before the reference date of the interview, or (b) it is a type of condition that ordinarily has a duration of more than 3 months. Examples of conditions that are considered chronic regardless of their time of onset are diabetes, heart conditions, emphysema, and arthritis. A complete list of these conditions may be obtained by contacting the Division of Health Interview Statistics, National Center for Health Statistics. Impairment —An impairment is a chronic or permanent defect, usually static in nature, that results from disease, injury, or congenital malformation. It represents a decrease in or loss of ability to perform various functions, particularly those of the musculoskeletal system and the sense organs. Impairments are grouped according to type of functional impairment and etiology in the special NHIS impairment codes. Acute condition—A condition is considered acute if (a) it was first noticed no longer than 3 months before the reference date of the interview, and (b) it is not one of the conditions considered chronic regardless of the time of onset. (See definition of chronic condition.) However, any acute condition not associated with either at least one doctor visit or at least one day of restricted activity during the reference period is considered to be of minor consequence and is excluded from the final data produced by the survey. Onset of condition—A condition is considered to have had its onset when it was first noticed. This could be the time when the person first felt sick or became injured, or it could be the time when the person or family was first told by a physician that the person had a condition of which he or she had been previously unaware. Incidence of conditions—The incidence of a condition is the number of cases that had their onset during a specified period of time. A person may have more than one acute condition during a period of time or may have the same condition, such as a headache, more than once. Ordinarily, however, a chronic condition is counted as beginning no more than once during a given reference period. Prevalence of conditions—The prevalence of a condition is the number of persons who have the condition at a given point in time. Although the prevalence of acute conditions is a meaningful concept, it is seldom used in health statistics, which generally focus on the incidence of acute conditions. If the prevalence of a chronic condition is measured during a period of time (for example, each week during a year), then the resulting estimate of prevalence is an average of 52 weekly prevalence estimates. This is called an average annual point prevalence estimate. 

# Terms Relating to Disability Disability—Disability is a general term that refers to any long- or short-term reduction of a person’s activity as a result of an acute or chronic condition. Limitation of activity refers to a long-term reduction in a person’s capacity to perform the average kind or amount of activities associated with his or her age group. Restriction of activity refers to particular kinds of behavior usually associated with areduction in activity due to either longor short-term conditions. Thus limitation of activity refers to what a person is generally capable of doing, but restriction of activity ordinarily refers to a relatively short-term reduction in a person’s activities below his or her normal capacity. Limitation of activity because of chronic conditions—Persons are classified in terms of the major activity usually associated with their particular age group. The major activities for the age groups are (a) ordinary play for children under 5 years of age, (b) attending school for those 5–17 years of age, (c) working or keeping house for persons 18–69 years of age, and (d) capacity for independent living (e.g., the ability to bathe, shop, dress, and eat without needing the help of another person) for those 70 years of age and over. People aged 18–69 years who are classified as keeping house are also classified by their ability to work at a job or business. (In this report, the major activity of persons 65–69 years is assumed to be working or keeping house; however, questions were also asked about the capacity for independent living in this age group, which would permit an alternative definition of limitation.) In regard to these activities, each person is classified into one of four categories: (a) unable to perform the major activity, (b) able to perform the major activity, but limited in the kind or amount of this activity, (c) not limited in the major activity, but limited in the kind or amount of other activities, and (d) not limited in any way. In regard to these four categories, NHIS publications often classify persons only by whether they are limited (groups a–c) or not limited (group d). Persons are not classified as limited in activity unless one or more chronic conditions are reported as the cause of the activity limitation. If more than one condition is reported, the respondent is asked to identify the condition that is the major cause of the limitation. Restriction of activity—Four types of restricted activity are measured in NHIS: bed days, work-loss days for currently employed persons 18 years of age and over, school-loss days for children 5–17 years of age, and cut-down days. A bed day is one during which a person stayed in bed more than half a day because of illness or injury. All Page 136 [ Series 10, No. 200

## hospital days for inpatients are considered bed days even if the patient was not in bed for more than half a day. A work-loss day is one on which a currently employed person 18 years of age and over missed more than half a day from a job or business. A school-loss day is one on which a student 5–17 years of age missed more than half a day from the school in which he or she was currently enrolled. A cut-down day is a day on which a person cuts down for more than half a day on the things he or she usually does. Work-loss, school-loss, and cut-down days refer to the short-term effects of illness or injury. However, bed days are a measure of both long- and short-term disability, because a chronically ill bedridden person and a person with a cold could both report having spent more than half a day in bed due to an illness. The number of restricted-activity days is the number of days on which a person experienced at least one of the four types of activity restriction just described. It is the most inclusive measure of disability days and the least descriptive; 4 days of restricted activity may mean 4 bed days associated with serious illness or 4 days during which a person merely cut down on his or her activities due to a mild illness. A single restricted-activity day may involve both a bed day and a work-loss or school-loss day. However, a cut-down day cannot overlap with any of these three types of disability days. In calculating the sum of restricted-activity days, each day is counted only once even if more than one type of activity restriction was involved. Restricted-activity days may be associated with either persons or conditions. Person days are the number of days during which a person restricted his or her activity. Condition days are the number of days during which a condition caused a person to restrict his or her activity. A person day of restricted activity can be caused by more than one condition. In such a case, each condition causing restriction is associated with that day of restricted activity. Therefore, the number of condition days of restricted activity may exceed the number of person days of restricted activity. This relationship holds for each type of restricted-activity day. When two or more conditions result in a day of restricted activity, the conditions may be (a) both (all) acute, (b) one (some) acute and the other (some) chronic, or (c) both (all) chronic. The number of restricted-activity days associated with acute conditions includes groups (a) and (b); the number of such days associated with chronic conditions includes groups (b) and (c). The phrase ‘‘associated with’’ rather than ‘‘caused by’’ is used to indicate that some days associated with acute or chronic conditions are not necessarily caused solely by that type of condition. Assessed health status—The categories related to this concept result from asking the respondent, ‘‘Would you say ___________’s health is excellent, very good, good, fair, or poor?’’ It is based on a respondent’s opinion and not directly on any clinical evidence. 

# Terms Relating to Persons Injured Injury condition—An injury condition, or simply an injury, is a condition of the type that is classified according to the nature-of-injury code numbers (800–999) in the Ninth Revision of the International Classification of Diseases (16). In addition to conditions such as fractures, lacerations, contusions, and burns, which are commonly thought of as injuries, this group of codes includes poisonings and impairments caused by accidents or nonaccidental violence. Unless otherwise specified, the term injury is used to cover all of these. A person may sustain more than one injury in a single accident (for example, a broken leg and laceration of the scalp), so the number of injury conditions may exceed the number of persons injured. Statistics of acute injury conditions include only injuries that involved medical attendance or at least a half day of restricted activity. E-codes and place of occurrence—Beginning in 1993, the NHIS began collecting additional data to create detailed cause-of-injury classifications using ‘‘E-codes’’ (Supplementary Classification of External Causes of Injury and Poisoning) for injuries, poisonings, and other adverse medical reactions along with place of occurrence. Episodes of persons injured —Each time a person is involved in an accident or nonaccidental violence causing injury that results in medical attention or at least a half day of restricted activity, it is counted as a separate episode of a person injured. Therefore, one person may account for more than one episode of a person injured. The number of episodes of persons injured is not equivalent to the number of accidents for several reasons: (a) the term ‘‘accident’’ as commonly used may not involve injury at all; (b) more than one injured person may be involved in a single accident, so the number of accidents resulting in injury would be less than the number of persons injured in accidents; and (c) the term ‘‘accident’’ ordinarily implies an accidental origin, whereas ‘‘persons injured’’ as used in the NHIS includes persons whose injuries resulted from certain nonaccidental violence. The number of episodes of persons injured in a specified time interval is equal to or less than the incidence of injury conditions because a person may incur more than one injury in a single accident. 

# Terms Relating to Accidents Motor vehicle—A motor vehicle is any mechanically or electrically powered device, not operated on rails, on which or by which a person or property can be transported or drawn on a land highway. Any object being towed by a motor vehicle (such as a trailer, coaster, sled, or wagon) is considered a part of the motor vehicle. Devices used solely for moving persons or materials within the confines of a building and its premises are not counted as motor vehicles. Series 10, No. 200 [ Page 137

## Moving motor vehicle accident —An accident is classified as involving a ‘‘moving motor vehicle’’ if at least one of the motor vehicles involved in the accident was moving at the time of the accident. This category is divided into ‘‘traffic’’ and ‘‘nontraffic’’ accidents. Traffıc moving motor vehicle accident —An accident is in the ‘‘traffic’’ category if it occurred on a public street or highway. It is considered to have occurred on the highway if it occurred wholly on the highway, originated on the highway, terminated on the highway, or involved a vehicle partially on the highway. (See ‘‘street or highway.’’) Nontraffıc moving motor vehicle accident —The accident is in the ‘‘nontraffic’’ category if it occurred entirely in any place other than a public street or highway. Street or highway—‘‘Street or highway’’ means the entire width between property lines of a way or place, any part of which is open for use by the public as a matter of right or custom. This includes more than just the traveled part of the road. ‘‘Street or highway’’ includes the entire right-of-way. Public sidewalks are part of the street, but private driveways, private lanes, private alleys, and private sidewalks are not considered part of the street. Nonmoving motor vehicle accident —If the motor vehicle was not moving at the time of the accident, the accident is considered a ‘‘nonmoving motor vehicle’’ accident and is classified in the ‘‘other accident’’ category. (See ‘‘other accident.’’) Accident while at work —An accident is classified as ‘‘while at work’’ if the injured person was 18 years of age or over and was at work at a job or business at the time the accident happened. Home accident —An accident is classified as ‘‘home accident’’ if the injury occurred either inside or outside the house. ‘‘Outside the house’’ refers to the yard, building, and sidewalks on the property. ‘‘Home’’ includes not only the person’s own home, but also any other home in which the person may have been injured. Industrial place—This category includes factory buildings, railway yards, warehouses, workshops, loading platforms of factories or stores, construction projects (houses, buildings, bridges, new roads, and the like), as well as buildings undergoing remodeling. However, accidents in private homes undergoing remodeling are classified as home accidents. Other accident —This category includes injuries in public places (such as tripping and falling in a store or on a public sidewalk) and also nonaccidental injuries such as homicidal and suicidal attempts. The survey does not cover the military population, but current disability of various types resulting from prior injury that occurred while the person was in the armed forces is covered and is included in this class. 

# Terms Relating to Physician Contacts Physician contact —A physician contact is defined as consultation with a physician, in person or by telephone, for examination, diagnosis, treatment, or advice. (Physician contacts with hospital inpatients are not included.) The contact is considered to be a physician contact if the service is provided directly by the physician or by a nurse or other person acting under a physician’s supervision. For the purpose of this definition, ‘‘physician’’ includes doctors of medicine and osteopathic physicians. The term ‘‘doctor’’ is used in the interview rather than ‘‘physician’’ because of popular usage. However, the concept toward which all instructions are directed is that which is described here. Physician contacts for services provided on a mass basis are not included in the tabulations. A service received on a mass basis is defined as any service involving only a single test (such as a test for diabetes) or a single procedure (such as a measles inoculation) when this single service is administered identically to all persons who are at the place for this purpose. Hence, obtaining a chest x ray in a tuberculosis chest x-ray trailer is not included as a physician contact. However, a special chest x ray given in a physician’s office or in an outpatient clinic is considered a physician contact. If a physician is called to a house to see more than one person, the call is considered a separate physician contact for each person about whom the physician is consulted. A physician contact is associated with the person about whom the advice is sought, even if that person does not actually see or consult the physician. For example, if a mother consults a physician about one of her children, the physician contact is ascribed to the child. Place of contact —The place of contact is a classification of the type of place at which a physician contact took place. The definitions of the various categories are as follows: Telephone . Refers to medically related matters discussed in a telephone call with a physician or physician’s assistant. Calls for nonmedically related matters (such as for an appointment) are not included. Offıce . Refers to physician offices that are not located in a hospital. Hospital . Involves three types of places in a hospital: emergency room, clinic, and doctor’s office. Other. Any place not classified into one of the three categories specified above, including clinics and HMO’s not located in hospitals. Interval since last physician contact —The interval since the last physician contact is the length of time prior to the week of interview since a physician was last consulted in person or by telephone for treatment or advice of any type whatever. A physician contact with a hospital inpatient can be counted as the last time a physician was seen, even though it is not included in the ‘‘physician contact’’ category. 

# Terms Relating to Hospitalization Hospital —For this survey, a hospital is defined as any institution either (a) named in the listing of hospitals in the current American Hospital Association Guide to the Health Care Field (33), or (b) found on the Master Facility Inventory List maintained by the National Center for Health Statistics. Page 138 [ Series 10, No. 200

## Short-stay hospital —A short-stay hospital is one in which the type of service provided is general; maternity; eye, ear, nose, and throat; children’s; osteopathic. It may also be the hospital department of an institution. Hospital day—A hospital day is a day on which a person is confined to a hospital. It is counted as a hospital day only if the patient stays overnight. Thus, a patient who enters the hospital on Monday afternoon and leaves by Wednesday at noon is considered to have had two hospital days. Hospital days during the year —The number of hospital days during the year is the total number for all hospital episodes in the 12-month period prior to the interview week. For this estimate, episodes overlapping the beginning or end of the 12-month period are subdivided so that only those days falling within the period are included. Hospital episode—A hospital episode is any continuous period of stay of one night or more in a hospital as an inpatient, except the period of stay of a well newborn infant. A hospital episode is recorded for a family member whenever any part of that person’s hospital stay is included in the 12-month period prior to the interview week. Hospital discharge—A hospital discharge is the completion of any continuous period of stay of one night or more in a hospital as an inpatient, except the period of stay of a well newborn infant. A hospital discharge is recorded whenever a present member of the household is reported to have been discharged from a hospital in the 12-month period prior to the interview week. (Estimates were based on discharges that occurred during the 6-month period prior to the interview.) Length of hospital stay—The length of hospital stay is the duration in days, exclusive of the day of discharge, of a hospital stay. (See ‘‘hospital discharge.’’) Average length of stay—The average length of stay per discharged patient is computed by dividing the total number of hospital days for a specified group by the total number of discharges for that group. 

# Demographic Terms Age—The age recorded for each person is the age at last birthday. Age is recorded in single years and grouped using a variety of age categories depending on the purpose of the table. Geographic region—For the purpose of classifying the population by geographic area, the States are grouped into four regions. These regions, which correspond to those used by the U.S. Bureau of the Census, are as follows: Region States included Northeast Maine, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, New York, New Jersey, and Pennsylvania Midwest Ohio, Illinois, Indiana, Michigan, Wisconsin, Minnesota, Iowa, Missouri, North Dakota, South Dakota, Kansas, and Nebraska South Delaware, Maryland, District of Columbia, West Virginia, Virginia, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Oklahoma, Arkansas, and Texas West Washington, Oregon, California, Nevada, New Mexico, Arizona, Idaho, Utah, Colorado, Montana, Wyoming, Alaska, and Hawaii Place of residence—The place of residence of a member of the civilian noninstitutionalized population is classified as inside a metropolitan statistical area (MSA) or outside an MSA. Place of residence inside an MSA is further classified as either central city or not central city. Place of residence outside an MSA is further classified as either farm or nonfarm. Metropolitan statistical area—The definition and titles of MSA’s are established by the U.S. Office of Management and Budget with the advice of the Federal Committee on Metropolitan Statistical Areas. Generally, an MSA consists of a county or group of counties containing at least one city (or twin cities) having a population of 50,000 or more, plus adjacent counties that are metropolitan in character and are economically and socially integrated with the central city. In New England, towns and cities rather than counties are the units used in defining MSA’s. There is neither a limit to the number of adjacent counties included in the MSA if they are integrated with the central city, nor is an MSA limited to a single State; boundaries may cross State lines. The metropolitan populations in this report are based on MSA’s as defined in the 1990 Census and do not include any subsequent additions or changes. Central city of an MSA—The largest city in an MSA is always a central city. One or two additional cities may be secondary central cities in the MSA on the basis of either of the following criteria: 1. The additional city or cities must have a population one-third or more of that of the largest city and a minimum population of 25,000. 2. The additional city or cities must have at least 250,000 inhabitants. Not central city of an MSA—This includes all of the MSA that is not part of the central city itself. Not in MSA—This includes all other places in the country except MSA’s. Race—The population was divided into three racial groups: ‘‘white,’’ ‘‘black,’’ and ‘‘all other.’’ ‘‘All other’’ included Aleut, Eskimo or American Indian, Asian or Pacific Islander, and any other race not listed separately. Since 1992, NHIS has expanded race into 15 detailed racial groupings and an ‘‘other race’’ category (see appendix III, section A, question 6a). If a person reported more than one race and did not select one main race, then he or she is assigned ‘‘multiple race’’ in the data file. Race characterization is based on the respondent’s description of his or her racial background as well as the racial background of each family member. Income of family or of unrelated individuals—Each member of a family is classified according to the total income of the family of which he or she Series 10, No. 200 [ Page 139

## is a member. Within the household, all persons related to each other by blood, marriage, or adoption constitute a family. Unrelated individuals are classified according to their own incomes. The income recorded is the total of all income received by members of the family (or by an unrelated individual) in the 12-month period preceding the week of interview. Income from all sources—for example, wages, salaries, rents from property, pensions, government payments, and help from relatives—is included. Currently employed —Persons 18 years of age and over who reported that at any time during the 2-week period covered by the interview they either worked at or had a job or business are currently employed. Current employment includes paid work as an employee of someone else; self-employment in business, farming, or professional practice; and unpaid work in a family business or farm. Persons who were temporarily absent from a job or business because of a temporary illness, vacation, strike, or bad weather are considered as currently employed if they expected to work as soon as the particular event causing the absence no longer existed. Freelance workers are considered currently employed if they had a definite arrangement with one employer or more to work for pay according to a weekly or monthly schedule, either full time or part time. Excluded from the currently employed population are persons who have no definite employment schedule but work only when their services are needed. Also excluded from the currently employed population are (a) persons receiving revenue from an enterprise, but not participating in its operation, (b) persons doing housework or charity work for which they receive no pay, (c) seasonal workers during the portion of the year when they were not working, and (d) persons who were not working, even though having a job or business, but were on layoff and looking for work. The number of currently employed persons estimated from the NHIS will differ from the estimates prepared from the Current Population Survey (CPS) of the U.S. Bureau of the Census for several reasons. In addition to differing because of sampling variability, there are three primary conceptual differences. They are: 1. The NHIS estimates are for persons 18 years of age and over; CPS estimates are for persons 16 years of age and over. 2. The NHIS uses a 2-week reference period, while CPS uses a 1-week reference period. 3. The NHIS is a continuing survey with separate samples taken weekly; CPS is a monthly sample taken for the survey week that includes the 12th of the month. The most detailed operational definitions of these terms are in the NHIS Field Representative’s Manual (34). Instructions are given in the manual on how problem cases associated with each concept are to be handled. Page 140 [ Series 10, No. 200
