Executive Summary 

Housing is an important social determinant of health, yet little systematic evidence exists about the 

health of U.S. Department of Housing and Urban Development (HUD)-assisted households. Current 

knowledge and understanding of the health of the nation’s assisted housing population is based primarily 

on case studies and anecdotes.1This knowledge gap is being addressed through an interagency effort 

between the Centers for Disease Control and Prevention, National Center for Health Statistics and HUD. 

National Health Interview Survey (NHIS) responses were linked with HUD’s administrative data on rental 

assistance programs. For the first time, reliable estimates of the prevalence of health conditions and 

healthcare utilization among HUD-assisted individuals—including adults and children—are now available 

at a national level (Sperling and Helms, 2016).

This report focuses on the health of children in HUD-assisted households.2 Among the 5 million 

households and 10 million individuals receiving HUD rental housing assistance, approximately 4 million 

are children, representing nearly 6 percent of all children in the United States.

3

This report describes the 

health characteristics of HUD-assisted children using various NHIS variables. Findings establish a baseline 

that can inform policymakers and stimulate further research. Comparative data for two relevant child

groups—children residing in unassisted low-income renter households and the general child population—

are provided for context. Differences between groups are not tested for statistical significance.

Analyses revealed that important health status indicators characterize the population of HUD-assisted 

children. Major findings are highlighted in the following list.

• Sociodemographic characteristics of HUD-assisted children. Most HUD-assisted children were Black

(52.2 percent). The largest proportion resided in the South (44.1 percent). Most HUD-assisted

children lived in a single-parent, female-headed household (74.6 percent). Additionally, a large

proportion resided in large metropolitan centers (31.9 percent), and 40.7 percent had a family

income that was less than one-half of the federal poverty threshold (based on poverty levels for

2012).

4

• Health status of children ages 0–17 years. Among HUD-assisted children, 5.2 percent had a

knowledgeable adult report their health as fair or poor. HUD-assisted children were frequent users of

the emergency room. During the year prior to the interview, 14.2 percent of HUD-assisted children

visited the emergency room two or more times. A high percentage of HUD-assisted children (21.2

percent) had current asthma.

• Learning-related health status of school-aged children (ages 6–17). Among HUD-assisted children, 16.2

percent of school-aged children missed 6 to 10 days of school during the previous year, and 8.5

1 For some exceptions, see Ahrens et al. (2016) and Fenelon et al. (2017). Authors used the same HUD-National 

Center for Health Statistics linked data to support findings.

2 A previous report focused on HUD-assisted adults. See Helms, Sperling, and Steffen (2017). 

3 Estimate based on statistics published by the Federal Interagency Forum on Child and Family Statistics (2016). 

4 Based on 2012 poverty thresholds published by the Census Bureau, a ratio of family income to the poverty 

threshold of less than 0.5 translates to an annual household income no greater than $9,249 for a family of three 

with one adult and two children (U.S. Census Bureau, 2017).

percent missed 11 or more days. School-aged, HUD-assisted children experience high rates of 

learning disabilities: 26.5 percent of children had any learning disability reported by a school or health 

professional; this included 16.1 percent who had been diagnosed with attention deficit hyperactivity 

disorder or attention deficit disorder and 10.4 percent ever diagnosed with some other kind of 

learning disability. 

• Healthcare access among children ages 0–17. Most HUD-assisted children ages 0–17 years had

insurance coverage via public health insurance programs (86.8 percent). A smaller proportion of

children were uninsured among the HUD-assisted population (4.1 percent) than among the general

child population (8.2 percent). Additionally, the percentage of children with unmet medical needs

due to cost was similar among HUD-assisted children (3.5 percent) and children in the general

population (4.4 percent). Most HUD-assisted children had a well-child visit (84.4 percent) or general

doctor visit (85.9 percent) during the prior year.

• Healthcare access among school-aged children (ages 6–17). Among HUD-assisted children ages 6–17,

8.3 percent reported unmet dental healthcare needs due to cost. Most (81.1 percent) HUD-assisted

children ages 6–17 had obtained oral health services during the prior year. A small percentage (2.5

percent) of HUD-assisted children reported unmet mental healthcare needs. In addition, 16.1 percent

of HUD-assisted children saw a mental health professional during the prior 12 months. In HUDassisted households, 5.6 percent of children were reported to need eyeglasses but did not get them

because the family was unable to afford them.

Descriptive analyses show clear differences between HUD-assisted children, children residing in lowincome, unassisted households, and children in the general population. The differences reported here 

were not tested for statistical significance, but the findings underscore the need for further research to 

better understand the connection between rental housing assistance programs administered by HUD and 

the health of children in HUD-assisted households.

Introduction 

The U.S. Department of Housing and Urban Development (HUD) provides rental housing assistance to 

approximately 5 million households and 10 million low-income individuals. Approximately 40 percent of 

HUD-assisted tenants—more than four million—are children. Children living in HUD-assisted households 

represent nearly 6 percent of all children in the United States.5This report presents a broad overview of 

the health characteristics of HUD-assisted children using various health survey metrics to establish a 

baseline to inform policymakers. Comparative data for two relevant child groups, (1) children residing in 

unassisted low-income renter households and (2) the general child population, are provided for context. 

Descriptive statistics are presented for children ages 0–17 and for school-aged children ages 6–17. 

Housing as a Social Determinant of Health 

Recently, housing policymakers and public health 

professionals have recognized the need to understand

housing as a social determinant of health. Housing 

influences health in many ways. First, housing 

affordability is central to a family’s financial stability. 

For most American families, housing costs represent 

their largest monthly expenditure.6 For homeowners, 

housing is often a family’s greatest financial asset. 

Geographic location and neighborhood characteristics 

are also important determinants of health, including 

factors such as access to transportation, education, 

and health care. To obtain affordable rents without 

housing assistance, some low-income families are 

forced to accept inadequate and unsafe housing and 

live in hazardous neighborhoods. 

Prioritizing Housing as a Social Determinant of 

Health in Healthy People 2020 

Recognizing the need to gain a better 

understanding of the social causes of morbidity 

and mortality, the U.S. Department of Health and 

Human Services recently added Social 

Determinants of Health (SDOH) as a core focus 

area in Healthy People 2020 (HP2020). The 

HP2020 program establishes a set of nationwide 

health-promotion and disease-prevention goals 

to be achieved by the year 2020. One-third of 

SDOH data performance objectives measure 

poverty, housing cost burden, or both, further 

indicating the need to prioritize housing as a key 

SDOH (HP2020, 2016). 

Physical conditions within a home can have a significant impact on physical health. Most Americans spend 

more than half of their time inside their homes. Inadequate units pose health risks through such 

conditions as pest infestations, dampness and mold, lead-based paint hazards, injury hazards, inadequate 

ventilation and poor indoor air quality, and inadequate temperature control. Poor indoor environmental 

conditions, which may be combined with high-crime, polluted, or low-amenity neighborhoods, threaten 

both physical and mental health (Evans, Wells, and Moch, 2003; Fisk, Eliseeva, and Mendell, 2010; Krieger 

and Higgins, 2002).

 In 2015, 8.3 million very low-income renter households lacked housing assistance and faced severe cost burdens, 

severely inadequate housing units, or both. HUD classifies housing costs between 30 and 50 percent of income as 

moderate cost burdens, and housing costs exceeding 50 percent of income as severe housing cost burdens (Watson 

et al., 2017).

Descriptive statistics in this report aim to provide 

new insights into the link between subsidized 

housing and children’s health. The report seeks to

encourage focused research using the HUDNational Center for Health Statistics (NCHS) data 

linkage. Health status and healthcare utilization 

outcomes for children in HUD-subsidized 

households are summarized alongside estimates 

for children in unsubsidized renter households 

with incomes below the federal poverty line and 

children in the general population. Comparisons 

provide context for findings about HUD-assisted 

children but are not statistically valid comparisons.

HUD Rental-Assistance Programs 

This report focuses on HUD-assisted children, 

defined to include children residing in households 

receiving one of HUD’s three major rental subsidy 

program types—public housing, housing choice 

vouchers (HCVs),

7

and assisted multifamily

housing.

8 Public housing and HCVs are 

administered by state and local public housing 

agencies (PHAs). Within multifamily programs, in 

contrast, private building owners contract directly 

with HUD to make units available at subsidized rents. For all three program types, housing providers 

verify income eligibility of subsidized renters and submit tenant data to HUD, which sets the level of 

tenant rent contributions. Most tenants have incomes substantially below 50 percent of Area Median 

Income (AMI)9 on admission. 

Households that receive HUD assistance may differ from the general population of all households eligible 

for HUD assistance. For instance, households receiving assistance tend to be poorer, be older, have more 

disabilities, and be more likely to have a history of homelessness than the group of all eligible households.

Therefore, the health of children living in assisted households might differ from the health of children in 

the larger group of eligible households because of these selection processes. Additional research should

make health comparisons between the presented populations with respect to selection into HUD 

programs. 

7 HCVs are also known as tenant-based rental assistance. 

8Historically, assisted multifamily programs also have been referred to as project-based rental assistance. 

9HUD estimates AMI based on metropolitan areas, identified by the Census Bureau, and the nonmetropolitan 

balance of states. The term very low income refers to incomes of no more than 50 percent of AMI, with adjustments 

for family size. The definitions of low income, very low income, and extremely low income are outlined in the United 

States Housing Act of 1937, as amended.

HUD-NCHS Data Linkage Sources 

In collaboration with HUD, the NCHS linked longitudinal HUD administrative data with two cross-sectional 

health interview surveys across a 14-year period (1999 through 2012)—the National Health Interview 

Survey (NHIS) and the National Health and Nutrition Examination Survey.10 This report focuses on 

prevalence estimates produced from NHIS-HUD linked data from 2006 to 2012.

National Health Interview Survey 

The NHIS11 is an annual cross-sectional interview 

survey of approximately 35,000 households (90,000 

participants). NHIS is designed to monitor the health 

of the civilian noninstitutionalized U.S. population by 

collecting data on a broad range of health topics. 

The sampling plan follows a multistage area 

probability design that permits the representative 

sampling of households and noninstitutionalized

group quarters. 

The core NHIS questionnaire contains four major 

components. The Household component collects limited demographic information for all individuals living 

in a housing unit. For example, this file captures the number of household members who did and did not 

respond and the household’s type of living quarters. The Family component collects and verifies 

additional demographic information on each member in the housing unit and collects data on topics 

including health status, injuries, healthcare access and utilization, and health insurance. From each family, 

NCHS randomly selects one sample adult and one sample child (if any children are present) to collect 

more detailed information. The sample adult is interviewed directly, and an adult who is familiar with the 

child (a knowledgeable adult) gives information about the selected sample child. This report largely 

focuses on information collected from the Sample Child survey component. 

HUD Administrative Data 

HUD-affiliated housing providers collect administrative data on families participating in HUD assistance 

programs and transmit these data to HUD. Information collected includes—

• Dates of enrollment, income recertification, and end of participation.

• Name of each person living in the housing unit and personal attributes including sex, race, Social

Security number, date of birth, and relationship to the head of household.

• Family characteristics that might qualify the family for tenant selection preferences.

documentation, public use feasibility files, and analytic guidelines (Lloyd and Helms, 2016). 

11 For more information about NHIS, see NCHS (2013a). 

12 For example, some public housing and assisted multifamily units are designated for people with disabilities, and 

homeless individuals and families may receive preferential admission. Selection preferences vary across PHAs.

• Detailed income and assets information for all household members.

• Anticipated family income for the next 12 months and sources of that income.

• Geographic information for assisted units.

The federal forms used to collect HUD administrative data are forms HUD-50058,

13 HUD-50058 MTW,14

and HUD-50059.

15 The data are stored in two databases—the Public and Indian Housing Information 

Center contains information public housing and the HCV program and the Tenant Rental Assistance 

Certification System contains information on properties subsidized by programs of HUD’s Office of 

Multifamily Housing.

16

 

13 Administrative Form HUD–50058, the Family Report, is used to collect data on people who participate in the HCV 

and public housing programs. 

14 PHAs participating in the Moving to Work (MTW) demonstration have fewer data requirements. Form HUD–50058 

MTW (MTW Family Report) is used only by PHAs participating in MTW. 

15 Administrative Form HUD–50059, titled “Owners Certification of Compliance with HUD’s Tenant Eligibility and 

Rent Procedures,” is used to collect data on the people who participate in multifamily programs.

(2016).

Child Groups Examined 

Analyses examined sociodemographic characteristics and health outcomes among three groups of 

children ages 17 or younger, defined by income and status of HUD assistance during survey years 2006 to 

2012. This report focuses on HUD-assisted children and presents indicators for other child groups to 

provide useful context. The three child groups were defined as follows:

HUD-Assisted Children 

The primary group of interest for this study comprises linkage-eligible17 sample 

children in the NHIS who linked with HUD administrative data and received housing 

assistance at the time of health interviews during NHIS survey years 2006 to 2012.18

Children in this group lived in households that received one of three types of HUD 

rental assistance—HCVs,19 public housing, or multifamily housing. 

Unassisted Low-Income Children in Renter Households 

A second group represents linkage-eligible sample children who lived in unassisted 

rental units, did not link with HUD administrative data for the relevant years, and 

had household incomes below the federal poverty threshold.20 Renter status is 

based on NHIS responses, and individuals assisted by HUD at the time of interview 

are excluded from this group. Low-income renter households may be unassisted 

because the head of household did not apply for assistance, did apply but was not 

admitted to the program because of limited public resources,21 or was once assisted 

but is no longer assisted. 

General Child Population 

A final group examined was all linkage-eligible sample children from NHIS survey 

cycles 2006 to 2012. Children in this group represent the general child population 

without regard to income, housing tenure, or housing assistance status. This group 

does not exclude HUD-assisted children or children in low-income, renting 

households. 

17 Approximately 55 percent of NHIS survey participants were linkage-eligible during NHIS survey years 2006–2012. 

Details describing linkage eligibility criteria and linkage processes are described in Lloyd et al. (forthcoming) and 

Lloyd and Helms (2016).

18 Receipt of HUD assistance for NHIS participants was determined using the standard NCHS concurrency variables, 

which are based on the survey date being preceded and followed by HUD administrative records that are not more 

than 425 days apart, or 790 days apart for MTW agencies (Lloyd and Helms, 2016). 

19 The Homeownership Program and the Moderate Rehabilitation Single Room Occupancy Program, both included in 

the HCV program category, have a trivial effect on estimates. 

20 In this report, low income is used generically to mean incomes below the federal poverty threshold, which are 

comparable with the incomes of most HUD-assisted renters. The term neither means nor aligns with the 

substantially greater threshold of 80 percent of AMI that HUD uses to define which families are low income for 

purposes of program administration.

21 Only 25 percent of those eligible receive housing assistance. For more information regarding unmet housing 

needs, consult Watson et al. (2017).

Methods 

Data Linkage 

NCHS linked NHIS survey participant data to administrative records from HUD’s largest housing assistance 

programs using Social Security number, name, gender, and date of birth. Based on assurances and 

procedures to ensure confidentiality and privacy, the NCHS Research Ethics Review Board and HUD’s legal 

staff approved the data linkage.

The HUD-NCHS linkage was primarily a deterministic, rules-based matching process. The NHIS 

questionnaire, implemented since 1997, has core questions and supplements. From each family in the 

NHIS, one sample child is randomly selected from whom to collect information on the Sample Child

component. During NHIS survey years 2006 to 2012, information was collected from a knowledgeable 

adult about approximately 77,000 sample children. Among sample child survey participants, 

approximately 32 percent (N = 76,627) met linkage eligibility criteria. The respondent (that is, the 

knowledgeable adult) provided sufficient personal identifying information, provided linkage consent, and 

did not refuse to answer a question about housing assistance status (N = 25,018).

22 During NHIS survey 

years 2006 to 2012, approximately 1,516 children were linkage-eligible and received housing assistance at 

the time of their NHIS (NCHS, 2016). 

Statistical Analysis 

This report primarily uses data from the Sample Child component of NHIS. All tables display weighted 

percentages of demographic, socioeconomic, and health characteristics among children in the three 

groups and displayed percentages are estimated national prevalence rates. The appendix provides 

estimates of standard errors. Data were pooled across survey years 2006 to 2012 to ensure sufficient 

sample for statistically valid estimates.

Data analysis was performed using SAS software, version 9.4 (SAS Institute, Cary, NC), and SAS-callable 

SUDAAN, version 9.0 (RTI, Research Triangle Park, NC). NCHS adjusted NHIS sample weights, which 

account for nonresponse and for unequal probabilities of selection, to account for linkage eligibility. 

Weighted percentages were based on the linkage eligibility-adjusted sample weights, and standard errors 

of the percentages were estimated accounting for the complex survey sampling design (NCHS, 2013a).

Multiple imputation methods enabled the ratio of family income to the poverty threshold to be estimated 

without omitting cases that lack complete income data (NCHS, 2013b).

23

The report provides a broad descriptive summary of health characteristics of HUD-assisted children. This 

report does not test for causal associations. Moreover, side-by-side comparisons for the three child 

groups are designed to provide context for findings about HUD-assisted children. This report does not 

include statistical tests of differences between the groups compared. Analyses provide a general picture 

of the health of HUD-assisted children. 

 

22 Individuals who refused to answer questions regarding housing assistance status were presumed hesitant to share 

information regarding their housing situation; therefore, to protect confidentiality and respect privacy, these 

individuals were considered ineligible for data linkage with HUD administrative data.

23NCHS provided poverty ratio intervals in NHIS public use data files beginning with the 1997 NHIS. The poverty ratio 

is a ratio of the family’s income to the appropriate federal poverty threshold. Published poverty thresholds from the 

Census Bureau are used to calculate this ratio.

Sociodemographic Characteristics Among Children Ages 0–17 

Individual-level and household-level sociodemographic characteristics were examined among HUDassisted children, unassisted children in low-income renter households, and the general child population. 

Table A-1, in the appendix, displays weighted percentages and standard error estimates for each of the 

three groups examined.

Age at Interview 

The following three age categories were analyzed: 0 to 5, 6 to 11, and 12 to17 years. Among HUDassisted children, 35.6 percent were ages 0 to 5, 37.1 percent were ages 6 to 11, and 27.3 percent were 

ages 12 to 17. The proportion of children under age 5 was greatest (46.4 percent) among the unassisted, 

low-income renter household group (figure 1) and was similar among HUD-assisted children (35.6 

percent) and the general child population (33.8 percent). The percentage of children ages 6 to 11 was 

similar among all three groups. During the reference period, children residing in unassisted, low-income 

renter households had the smallest proportion of adolescents ages 12 to 17 (20.8 percent), and the 

general child population had the greatest proportion (33.7 percent). Generally, the age distribution was 

similar among HUD-assisted children and the general child population; however, children residing in lowincome, unassisted renting households tended to be younger than the other two child groups.

Sex 

Among all three child groups examined, the sex ratio is balanced (table A-1). All groups exhibit a male and 

female sex distribution around 50 percent. 

Race and Ethnicity 

Because of potential sample size limitations, race and ethnicity variables were recoded into four broad 

categories: Hispanic, non-Hispanic White, non-Hispanic Black, and non-Hispanic other (henceforth termed 

Hispanic, White, Black, and other). The racial and ethnic composition differs between the three child 

groups (figure 2). Among HUD-assisted children, most were Black (52.2 percent), followed by White 

(24.6 percent), Hispanic (20.3 percent), and other (3.0 percent). Among children residing in unassisted 

low-income renter households, one-third (35.2 percent) were Black, one-third (34.7 percent) were

Hispanic, and one-fourth (25.5 percent) were White. The general child population is less diverse, with 

56.8 percent White, 22.0 percent Hispanic, and 15.6 percent Black. Such differences between low-income 

renters, on the one hand, and the general child population, on the other, reflect the persistent 

association between poverty and minority status in the United States.

Region 

To ensure respondent confidentiality in the linked data set, the lowest level of geography available for 

aggregation and reporting using NHIS data is region. The United States is divided into four census 

regions—Northeast, Midwest, South, and West. 

Among HUD-assisted children, 15.0 percent resided in the Northeast, 26.8 percent resided in the 

Midwest, 44.1 percent resided in the South, and 14.2 percent resided in the West. When examining the

distribution of children by region among the three child groups, low-income renters—whether HUDassisted or not—were similar to the general child population (figure 3). For all three groups, a plurality of 

children resided in the South.

Metropolitan Classification 

An urban-rural classification schema developed by NCHS was used to examine urban-rural differences 

across child groups (NCHS, 2014). The measure defines U.S. counties and county-equivalent entities to 

one of six categories. The 2006 version used in this report is based on the 2000 census and the Office of 

Management and Budget’s 2005 delineation of metropolitan and micropolitan statistical areas.24

The most urban category consists of central counties of large metropolitan areas, and the most rural 

category consists of nonmetropolitan (referred to as “noncore”) counties. When listed from urbanity to 

rurality, metropolitan classification categories include—large central metro, large fringe metro, medium 

metro, small metro, micropolitan, and noncore. 

Most HUD-assisted children reside in metropolitan counties, including 31.9 percent in large central 

metropolitan counties, 13.2 percent in large fringe metropolitan counties, and 27.2 percent in medium 

metropolitan counties (figure 4). The urban-rural distribution was similar across the three child groups 

except that, relative to the general population, greater proportions of HUD-assisted and unassisted lowincome renter children were concentrated in the largest central metropolitan areas.

Ratio of Family Income to Poverty Threshold 

The NHIS provides an invaluable resource for studying the association between income and health.

However, NHIS nonresponse rates are high for the variables meant to capture total family income in the 

previous calendar year. To handle the problem of missing data on family income in the NHIS, multiple 

imputations were performed.25 Determining the ratio of family income to poverty threshold requires 

information on family size, structure, and income. The ratio was calculated using poverty thresholds 

published by the Census Bureau.

 

24 For more information about 2005 statistical areas, visit http://www.census.gov/programs-surveys/metromicro.html. 

25 For more information about multiple imputation of missing income data, see Schenker et al. (2006). 
A Health Picture of HUD-Assisted Children, 2006–2012 

Page 10

More than three-fourths of HUD-assisted children 

resided in households with incomes below the 

poverty threshold—40.7 percent of households 

had a ratio of family income to the poverty 

threshold below 0.5, and 35.6 percent had a ratio

between 0.5 and 1.0 (figure 5). Consistent with the

definition used to define the group, all children 

residing in unassisted low-income renter 

households had incomes below the federal poverty 

threshold. Dissimilarly, among the general 

population, one-half of children (51.5 percent) 

resided in households with family incomes 

exceeding twice the federal poverty threshold. 

Family Structure 

To determine family structure, variables meant to 

capture the presence of various family members 

were recoded to assess parental presence in a 

household.26 Family structure, in terms of parents 

present in the home, varied across the three child groups (figure 6). Most HUD-assisted children resided

in households with a mother and no father (74.6 percent), and few (3.2 percent) resided in households 

with neither a mother nor father. Similarly, most (65.3 percent) unassisted low-income renter children 

resided in households with a mother and no father. In contrast, most children (66.9 percent) in the 

general child population resided in household with a mother and a father, and 27.1 percent resided in 

households with a mother and no father present.

Highest Educational Attainment in Household 

Administrative data are not meant for research purposes, so data collection instruments collect 

information strictly pertinent to program participation. Extraneous nonprogram information generally 

cannot be collected without proper authorization. Thus, administrative systems often lack key 

sociodemographic variables, such as education level, for assessing social circumstance. The linked HUDNCHS data provide a mechanism to assess educational attainment among HUD-assisted families. The 

NHIS data include a recoded variable that captures the highest education level attained by any adult in 

the surveyed family. Previous research strongly suggests that parental educational level is a key predictor 

of child outcomes (Dubow, Boxer, and Huesmann, 2009). 

Only 4.3 percent of HUD-assisted children lived in a household in which at least one member had attained 

a bachelor’s degree or higher, and 22.7 percent resided in households in which no member held a high 

school diploma or a general educational development (GED) certificate (figure 7). Low-income unassisted 

children were even more likely to reside in a household in which no one had earned either a high school 

diploma or a GED (37 percent), and only 3.9 percent lived in a household in which a member had attained 

a bachelor’s or higher degree. The rate of living with someone who had attained at least a bachelor’s 

degree was much higher for children in the general population (32 percent).

Summary of Sociodemographic Characteristics Among HUD-Assisted Children Ages 0–17 

Descriptive statistics reveal important variations in the distribution of sociodemographic characteristics 

across the three child groups. Among HUD-assisted children, the largest proportions were Black (52.2 

percent), the region with the largest proportion of HUD-assisted children was the South (44.1 percent), 

and most HUD-assisted children lived in households with a mother but no father present (74.6 percent). 

Additionally, pluralities of nearly one-third of HUD-assisted children resided in large metropolitan centers 
A Health Picture of HUD-Assisted Children, 2006–2012 

Page 12

(31.9 percent), and very few lived in rural counties. Nearly one-half (40.7 percent) lived in households 

that had a ratio of family income to poverty threshold less than 0.5, which translates to approximately 

$9,249 (or less) for a family of three with one adult and two children.27

Consistent with prior research, substantial sociodemographic differences were evident between the two 

low-income groups and the general child population. For example, race and ethnicity varied across child 

groups. Family structure also varied—HUD-assisted children were mostly in single-parent families, as are 

low-income unassisted children, but the general child population had mostly two-parent families. Not 

presented in these data is the significant fact that most U.S. households, including households with 

children, are homeowners. The general population group thus includes homeowners, but the two renter 

groups do not include homeowners. This difference is important, because housing tenure has 

implications for the resources available to each group and for the health outcomes that follow (Pollack, 

Griffin, and Lynch, 2010).

Health Status Among Children Ages 0–17 

Analyses examined individual-level health characteristics among HUD-assisted children and two relevant

child groups. Underlying data are presented in appendix table A-2, including weighted percentages and 

standard error estimates for each group examined.

Reported Health Status 

The NHIS asks a knowledgeable household adult to rate the sample child’s general health status on the 

following five-point Likert scale—excellent, very good, good, fair, or poor. The distribution of general

health status varied across child groups examined (figure 8). Among HUD-assisted children, 5.2 percent of 

children had a fair or poor health status. This percentage was similar among unassisted, low-income 

renter children (6.1 percent). In contrast, among the general child population, 2.4 percent had fair or 

poor health.

Emergency Room Visits 

Frequent use of the emergency room (ER) can signal health status or health access issues. For example, 

repeated ER visits could indicate chronic health emergencies, such as asthma attacks or broken bones, or 

can signal lack of access to a regular doctor, inadequate preventive care, or an inability to afford the outof-pocket costs associated with office visits. Previous Centers for Disease Control and Prevention (CDC)

research suggests that children with Medicaid coverage are more likely to visit the ER than are uninsured 

children or children with private health insurance. As public health insurance programs cover most HUDassisted children (table A-4), this relationship is key to further understanding ER use among HUD-assisted 

children. The research also showed that most ER visits by children occur at night or on a weekend, 

regardless of their health insurance coverage, and that the main reason for ER visits by children is that the 

doctor’s office is not open (Gindi and Jones, 2014).

Among HUD-assisted children, 14.2 percent had two or more ER visits during the past 12 months, and 

20.6 percent had one visit (figure 9). The distribution by number of ER visits was similar among children in 
A Health Picture of HUD-Assisted Children, 2006–2012 

Page 14

unassisted, low-income renter households, of which 15.7 percent had two or more ER visits and 17.4 

percent had one ER visit in the past 12 months. Among the general child population, a smaller proportion, 

8.5 percent, had two or more ER visits and 14.8 percent had one ER visit. These results suggest that 

children in the general population may have a qualitatively different pattern of ER usage than the two 

groups of children residing in low-income, renter households.

Current Asthma 

Asthma is a potentially fatal inflammatory disease that affects the lungs and is characterized by episodes 

of wheezing, breathlessness, coughing, or chest tightness.28 Indoor environmental allergens, including 

those found in substandard housing such as cockroach infestations or mold, are significant asthma 

triggers. Early childhood exposure to cockroach allergen and mold have also been associated with asthma 

development (Do, Zhao, and Gao, 2016; Jaakkola, Hwang, and Jaakkola, 2005; Reponen et al., 2011).

Traffic-related air pollution, which may be more concentrated in low-income neighborhoods, also is 

associated with asthma development (Bowatte et al., 2015). NHIS sample children were considered to 

have current asthma if the knowledgeable adult answered affirmatively to the sample child (1) ever 

having had asthma and (2) still having asthma at the time of the health interview. 

Among HUD-assisted children, 21.2 percent had current asthma (figure 10). Among unassisted children in 

low-income renter households, 17.7 percent had current asthma, but only 11.3 percent of the general 

child population had current asthma.29 Such disparities in asthma prevalence suggest the possibility that 

poorly controlled asthma, including nighttime attacks, could be leading to greater ER use by children in 

the HUD-assisted and unassisted low-income renter groups.

 

28 For more information about asthma, visit https://www.cdc.gov/asthma/.

29 Previous research shows a similar pattern of asthma disparities among HUD-assisted adults. See Helms, Sperling, 

and Steffen (2017).

Among HUD-assisted children, 5.2 percent had a knowledgeable adult report their health as fair or poor. 

HUD-assisted children are frequent users of the ER. During the prior year, 14.2 percent of HUD-assisted 

children visited the ER two or more times. Additionally, a high percentage of HUD-assisted children (21.2 

percent) had current asthma, indicating the need to further assess asthma rates and asthma-related 

disease among HUD-assisted children to consider cost-effective interventions.

Learning-Related Health Status Among School-Aged Children Ages 6–17 

For school-aged children, the NHIS 

collects several indicators relevant for 

understanding school performance, 

including school days missed due to 

illness or injury and learning disability 

status. This analysis examined such 

indicators among school-aged HUDassisted children, children in 

unassisted low-income households, 

and children in the general child 

population. 

For the purposes of this report, 

school-aged was defined as children 

ages 6 to 17 years of age at the time of their health interview. Data are presented in table A-3, including 

weighted percentages and standard error estimates for each of the three child groups.

School Days Missed 

To assess the number of school days missed due to injury or illness, the following interview question was 

asked about sample children ages 5 to 17 years: During the past 12 months, about how many days did 

{Sample Child} miss school because of illness or injury?

Among HUD-assisted children, 16.2 percent of school-aged children missed 6 to 10 days of school during the 

previous year, and 8.5 percent missed 11 or more days due to illness or injury (figure 11). Rates were similar 

for children in unassisted, low-income renter households, with 13.8 percent missing 6 to 10 days of school 

and 8.7 percent missing 11 or more days of school. Among children in the general population, 12.2 percent 

missed 6 to 10 days of school during the previous year due to illness or injury, and 6.3 percent missed 11 or 

more days.

Any Learning Disability 

Learning disorders are difficulties that a child experiences with one or more areas of learning that may or 

may not affect overall intelligence or motivation. Learning disability symptoms include difficulties 

concentrating, remembering instructions, and understanding the concept of time (CDC, 2017). Among 

NHIS sample children,

30 the following question was used to assess the prevalence of learning disabilities: 

Has a representative from a school or a health professional ever told you that {Sample Child} had a 

learning disability? Among HUD-assisted children, more than one-fourth (26.5 percent) of children ages 6

to 17 years had a learning disability reported by a school or health professional (figure 12). The 

prevalence of any learning disability was similar among children in unassisted, low-income renter 

households (24.4 percent), but among children in the general population, only 20.0 percent had a 

learning disability as reported by a school or health professional. The “any learning disability” metric 

included the most prevalent type of learning disorder among children, attention deficit hyperactivity 

disorder (ADHD) or attention deficit disorder (ADD).

Attention Deficit Hyperactivity Disorder or Attention Deficit Disorder 

One of the most prevalent learning disorders among children is attention deficit hyperactivity disorder

(ADHD) or attention deficit disorder (ADD). ADHD/ADD, characterized by trouble paying attention, is a 

common neurodevelopmental disorder among children that often continues into adulthood. The CDC 

estimates that in 2011, 11 percent of children ages 4 to 17 years were diagnosed with ADHD/ADD (CDC, 

2016). To assess the prevalence of ADHD/ADD, the following survey question was employed: Has a doctor 

or health professional ever told you that {Sample Child} had [...] attention deficit hyperactivity disorder 

(ADHD) or attention deficit disorder (ADD)? HUD-assisted children and children in unassisted low-income 

30 This question is asked for sample children ages 3–17; however, for this metric, this report limited the study

Among HUD-assisted children ages 6 to 17, 16.2 percent missed 6 to 10 days of school and 8.5 percent 

missed 11 or more days during the previous year due to illness or injury. School-aged, HUD-assisted 

children experienced high rates of learning disabilities. From 2006 through 2012, 26.5 percent of children 

had a learning disability reported by a school or health professional, including 16.1 percent diagnosed 

with ADHD or ADD and 10.4 percent with some other kind of learning disability. These results indicate 

that health issues and learning disorders place HUD-assisted children at high risk for difficulties in school 

and potentially adverse long-term outcomes.

Healthcare Access Among Children Ages 0–17 

The NHIS asks survey participants several questions about sources of health care, including health 

insurance coverage, access to general practitioners, medical specialists, and mental health professionals. 

Appendix table A-4 contains weighted percentages and standard error estimates for each of the three 

child groups examined.

Health Insurance Coverage 

The NHIS asks a series of questions about health insurance status. Children were considered to have 

public health insurance if they were reported to have coverage through any of the following health 

insurance providers—Medicaid, the State Children’s Health Insurance Program, a state-sponsored health 

plan, other government programs, or a military health plan.

31

Most HUD-assisted children had public health insurance (86.8 percent). Similarly, children in unassisted, 

low-income renter households also had high rates of public health insurance coverage (90.3 percent; 

figure 14). The distribution of health insurance coverage differed among children in the general 

population. Unlike the low-income child groups examined, approximately one-half (49.8 percent) of 

children in the general population had private health insurance, and 41.9 percent had public health 

insurance. Rates of uninsurance were similar among HUD-assisted children (4.1 percent) and children 

who resided in unassisted, low-income renter households (5.6 percent). Among children in the general 

population, 8.2 percent were uninsured.

Unmet Need for Health Care 

NHIS survey participants are asked a series of questions that can be used to determine unmet need for 

health care. The questionnaire includes a series of questions about needs that remained unmet due to 

cost. For sample children, a knowledgeable household adult was asked the following questions: During 

the past 12 months, was there any time when {Sample Child} needed [prescription medicines, mental 

health care or counseling, dental care (including checkups), or eyeglasses], but didn’t get it because you 

couldn’t afford it?

Sample children for whom a knowledgeable household adult answered yes to any of the four questions 

about unaffordable services were considered to have unmet need for healthcare services due to cost. 

Among HUD-assisted children, 10.9 percent were reported have unmet healthcare need due to cost

(figure 15). This estimate compared with 12.1 percent among children in unassisted, low-income renter

households and 10.5 percent among the general child population.

To assess unmet need for prescription medications, the NHIS asked the following question: During the 

past 12 months, was there any time when {Sample Child} needed prescription medicines, but didn’t get it 

because you couldn’t afford it? The percentage of children who needed but did not get prescription 

medication because the adult respondent could not afford the medication was similar among HUDassisted children (2.9 percent) and the general child population (3.1 percent; figure 16). Among 

unassisted children in low-income, renter households, 5.0 percent faced cost-related unmet need for 

prescription medication.

did not get it because {you} couldn’t afford it? Among HUD-assisted children, 3.5 percent had unmet 

medical care needs (figure 17). Rates were similar among children in unassisted, low-income renter

Well-Child Visits 

To assess the occurrence of regular physicals and well-child visits, the following questions were asked: 

During the past 12 months, did {Sample Child} receive a well-child checkup—that is, a general checkup 

when {he/she} was not sick or injured? Consistent with the prevalence of public insurance, the prevalence 

of well-child visits among HUD-assisted children was high—84.4 percent had a well-child visit in the past 

year (figure 18). Among children in unassisted, low-income renter households, 80.2 percent had a wellchild visit during the prior 12 months. The prevalence of well-child visits among children in the general 

population was 76.8 percent.

General Doctor Visits 

The NHIS asks survey participants several questions about healthcare sources, including the following 

question meant to capture whether the sample child had contact with a general practitioner during the 

prior year: During the past 12 months, have you seen or talked to the following about [Sample Child]’s

health? A general doctor who treats a variety of illnesses (a doctor in general practice, pediatrics, family 

medicine, or internal medicine)? Estimated rates of general doctor visits were similar to rates of well-child 

visits. Among HUD-assisted children, 85.9 percent had visited a general doctor during the prior year

(figure 19). Lower rates were observed among children in unassisted low-income renter households (83.3

percent) and the general child population (82.9 percent).

Specialist Visits 

To find out whether children in respondent households had visited a medical specialist, the NHIS included 

the following question: During the past 12 months, have you seen or talked to the following about 

{Sample Child}’s health? A medical doctor who specializes in a particular medical disease or problem. 

According to the survey instrument, a specialist is defined in NHIS as a “medical doctor who specializes in 

a particular medical disease or problem (other than obstetrician/gynecologist, psychiatrist or 

ophthalmologist).” Among HUD-assisted children, 14.4 percent were reported to have visited a specialist 

during the past year (figure 20). Children in the general population had slightly more visits to specialists 

(16.1 percent), and children in unassisted low-income renter households had slightly fewer (12.6 

percent).

No Usual Source of Care 

Usual source of health care among sample children was examined using the following question, which 

was asked to a knowledgeable adult: Is there a place that {Sample Child} usually goes when {he/she} is sick 

or needs advice about {his/her} health? If survey respondents said the sample child had no usual place, 

then the child was classified as having no usual source of care. In each of the three child groups, very few 

children lacked a usual source of care. HUD-assisted children were the least likely to lack a usual source of 

care (1.6 percent; figure 21). Among the general child population, a similar proportion of 2.7 percent 

lacked a usual source of care. Among unassisted low-income renter children, 3.3 percent were reported

to have no usual source of care.

Summary of Healthcare Utilization and Access Among Children Ages 0–17 

The clear majority of HUD-assisted children ages 0–17 years had insurance coverage via public health 

insurance programs (86.8 percent). HUD-assisted children were uninsured at a lower rate (4.1 percent) 

than uninsured children in the general child population (8.2 percent). The percentage of HUD-assisted 

children with unmet need for medical care (3.5 percent) was similar to the proportion among children in 

the general population (4.4 percent). Most HUD-assisted children were reported to have had a well-child 

visit (84.4 percent) or general doctor visit during the prior year (85.9 percent).

Healthcare Access Among School-Aged Children (Ages 6–17) 

The NHIS collects several indicators relevant for understanding the 

needs of school-age children, including dental care, mental health 

care, and eyeglasses affordability. This analysis examined such 

indicators among school-aged children in HUD-assisted households,

unassisted low-income renter households, and the general child 

population. For the purposes of this report, school-aged was defined 

as children ages 6 to 17 years at the time of their health interview.

Data for this age group are presented in table A-5. This table 

includes weighted percentages and standard error estimates for 

each of the three groups examined.

Dental Care Affordability 

Previous research suggests that low-income children receive fewer preventive dental care visits and have 

higher unmet dental care needs (Kenney, McFeeters, and Yee, 2005). To assess unmet needs for dental 

care, the following survey question was used: During the past 12 months, was there any time when 

{Sample Child} needed any of the following, but didn’t get it because you couldn’t afford it? Dental care 

(including checkups)? Rates among the three child groups were similar, ranging from 8.2 percent to 8.4 

percent (figure 22).

Dental Visits 

To capture dental visits during the prior year, the following NHIS question was used: About how long has 

it been since {Sample Child}’s last saw a dentist? Include all types of dentists, such as orthodontists, oral 

surgeons, and all other dental specialists, as well as dental hygienists. Sample children who saw a dentist 

in the past 12 months were considered to have obtained oral health services. Among HUD-assisted 

children, 81.1 percent reported a dental visit during the past year (figure 23). This rate slightly exceeded

the prevalence among children of unassisted low-income renters (79.8 percent) but was lower than the 

rate among children in the general population (84.5 percent).

Mental Healthcare Affordability 

The following question was used to measure unmet need for mental health care due to lack of 

affordability: During the past 12 months, was there any time when {Sample Child} needed any of the 

following, but didn’t get it because you couldn’t afford it? Mental health care or counseling? Rates were 

similar across all three child groups examined. Among HUD-assisted children, 2.5 percent were reported 

to have unmet mental healthcare need. Among the general child population, 1.5 percent of children had 

unmet mental healthcare need due to affordability (figure 24).

Mental Health Professional Visits 

The NHIS asks survey participants several questions about sources of health care, including the following 

question meant to capture whether a sample child had contact with a mental health professional: During 

the past 12 months, have you seen or talked to any of the following health care providers about {Sample 

Child}’s health? A mental health professional such as a psychiatrist, psychologist, psychiatric nurse, or 

clinical social worker. Among HUD-assisted children, 16.1 percent saw a mental health professional during 

the prior 12 months (figure 25), somewhat more than the 12.7 percent of unassisted low-income renters 

and 11.2 percent of the general child population that had visited a mental health professional.

Eyeglasses Affordability 

To assess unmet eyeglasses need due to affordability, a knowledgeable adult was asked the following 

question: During the past 12 months, was there any time when {Sample Child} needed eyeglasses, but 

didn’t get it because you couldn’t afford it? Rates of unmet eyeglass need were similar among HUDassisted children (5.6 percent) and children in unassisted low-income renter households (5.3 percent; 

figure 26). Among children in the general population, 3.2 percent reported needing eyeglasses but not 

having funds to afford them.

Among school-aged, HUD-assisted children, 8.3 percent were reported to have unmet dental healthcare 

needs due to cost. Most (81.1 percent) HUD-assisted children ages 6–17 had obtained oral health services 

during the prior year. A small percentage (2.5 percent) of HUD-assisted children were reported to have

unmet mental healthcare need. In addition, 16.1 percent of HUD-assisted children had seen a mental 

health professional during the prior 12 months. Among HUD-assisted children, 5.6 percent were reported

Conclusion 

Analyses provided a descriptive summary of the linked 2006-to-2012 HUD-NCHS data for HUD-assisted 

children. This report presents the first nationally representative estimates of the overall health status, 

including healthcare access and utilization, for HUD-assisted children. Findings represent a first step in 

sharing an important data resource for housing and health researchers and the general public. 

Although statistical testing between groups was not conducted, clear differences emerged when 

examining side-by-side estimates among HUD-assisted children, children residing in low-income, 

unassisted renter households, and children in the general population. Examining sociodemographic 

characteristics of the three child groups showed that unassisted, low-income children of renters and 

HUD-assisted children were similar, but that these groups differ substantially from the general child 

population. Notably, more than one-half of HUD-assisted children are Black; only one-third of low-income 

unassisted children and less than one-fifth of the general child populations are Black. HUD-assisted 

children and low-income unassisted children tend to live in major metropolitan areas, but the general 

child population is concentrated outside of these areas. Additionally, the educational attainment in HUDassisted families exceeds attainment of low-income unassisted families but is much lower than families in 

the general population. The demographic differences between child groups should be considered when

examining differences among the health indicators presented throughout this report. 

In terms of health status, HUD-assisted children are like other low-income, unassisted renter children. 

However, HUD-assisted children appear to have worse health status than children in the general 

population, despite appearing to have greater access to health care and higher utilization. For example, 

86.8 percent of HUD-assisted children had public health insurance, and 85.9 percent visited a general 

health doctor during the prior year. However, even with high rates of healthcare access, 14.2 percent of 

HUD-assisted children visited the ER two or more times during the prior year, and more than one-fifth of 

HUD-assisted children had current asthma. Poverty, quality of healthcare resources, and neighborhood 

conditions may account for much of these differences, but further research is needed to understand this 

relationship. 

School-aged, HUD-assisted children have high rates of learning disabilities: 26.5 percent had ever been 

told by a school or health professional that they had a learning disability, and 16.1 percent had been 

diagnosed with ADHD or ADD. In terms of dental healthcare needs, 8.3 percent of HUD-assisted children 

had unmet dental healthcare needs due to cost, but most (81.1 percent) had obtained oral health 

services during the prior year. HUD-assisted children had high mental healthcare needs. During the prior 

12 months, 16.1 percent had seen a mental health professional, and 2.5 percent were reported to have 

had unmet needs for mental health care.

Overall, the health status of HUD-assisted children is similar to children in unassisted, low-income renter 

households but several key findings emerged: HUD-assisted children are more likely to have asthma, 

more likely to miss school due to illness or injury, and are more often diagnosed with a learning disability. 

On other indicators, however, HUD-assisted children displayed some advantages over children in 

unassisted, low-income renter households, such as greater prevalence of health insurance and of wellchild preventive healthcare visits. Such conclusions, however, must be viewed as exploratory and 

preliminary. Assisted housing programs may shape selection mechanisms so that less-healthy populations 
A Health Picture of HUD-Assisted Children, 2006–2012 

Page 31

become assisted. For this reason, the descriptive nature of this research cannot determine the extent to 

which assisted housing influences health. Nevertheless, HUD-assisted populations have significant health 

needs that warrant attention by policymakers.

The United States makes substantial public investments in both housing and health care every year. Using 

these newly linked data to better align housing assistance programs and health policy has the potential to 

improve the cost effectiveness and outcomes of public investments. Considering that children are in 

vulnerable early stages of development, interventions to address specific health needs at an early stage 

or to better coordinate the existing health services available to assisted housing populations can yield 

great benefits during the life course for young, developing individuals and the broader society.
