Abstract

An estimated 88.2 percent of U.S. households were food secure throughout the entire year 

in 2017, meaning they had access at all times to enough food for an active, healthy life 

for all household members. The remaining households (11.8 percent) were food insecure 

at least some time during the year, including 4.5 percent with very low food security, 

meaning that at times the food intake of one or more household members was reduced 

and their eating patterns were disrupted because the household lacked money and other 

resources for obtaining food. Declines from 2016 in food insecurity overall and in very 

low food security were statistically significant. The rate of food insecurity declined from 

12.3 percent in 2016, and very low food security declined from 4.9 percent, continuing 

downward trends. Among children, changes from 2016 in food insecurity and very low 

food security were not statistically significant. Children and adults were food insecure in 

7.7 percent of U.S. households with children in 2017, versus 8.0 percent in 2016. Very low 

food security among children was 0.7 percent in 2017, essentially unchanged from 2016. 

In 2017, the typical food-secure household spent 23 percent more on food than the typical 

food-insecure household of the same size and household composition. About 58 percent 

of food-insecure households participated in one or more of the three largest Federal food 

and nutrition assistance programs (Supplemental Nutrition Assistance Program (SNAP, 

formerly food stamps); Special Supplemental Nutrition Program for Women, Infants, and 

Children (WIC); and the National School Lunch Program) during the month prior to the 

2017 survey.

Household Food Security in the United 

States in 2017

What Is the Issue?

Most U.S. households have consistent, dependable access to enough food for active, healthy 

living—they are food secure. But some households experience food insecurity at times during 

the year, meaning their access to adequate food is limited by a lack of money and other 

resources. USDA’s food and nutrition assistance programs increase food security by providing 

low-income households access to food for a healthful diet and nutrition education. USDA monitors the extent and severity of food insecurity in U.S. households through an annual, nationally 

representative survey sponsored and analyzed by USDA’s Economic Research Service (ERS). 

This report presents statistics from the survey that cover household food security, food expenditures, and use of Federal food and nutrition assistance programs in 2017.

What Did the Study Find? 

An estimated 11.8 percent of U.S. households were food insecure in 2017, down from 2016 and 

continuing a decline from a high of 14.9 percent in 2011, while still above the pre-recession 

(2007) level of 11.1 percent. The percentage of households with food insecurity in the severe 

range—very low food security—also declined. 

•	 In 2017, 88.2 percent of U.S. households were food secure. The remaining 11.8 percent 

(15.0 million households) were food insecure. Food-insecure households (those with 

low and very low food security) had difficulty at some time during the year providing 

enough food for all their members due to a lack of resources. The decline from 2016 (12.3 

percent) was statistically significant.

•	 In 2017, 4.5 percent of U.S. households (5.8 million households) had very low food 

security, down significantly from 4.9 percent in 2016. In this more severe range of food 

insecurity, the food intake of some household members was reduced and normal eating 

patterns were disrupted at times during the year due to limited resources.

•	 Children were food insecure at times during 2017 in 7.7 percent of U.S. households with 

children (2.9 million households), essentially unchanged from 8.0 percent in 2016. These 

households were unable at times to provide adequate, nutritious food for their children. 

As in 2015 and 2016, the 2017 prevalence of food insecurity among children was near the 

2007 pre-recession level of 8.3 percent.

Prevalence of food insecurity and very low food security in 2017 is down from 2016

 

Source: USDA, Economic Research Service using data from U.S. Department of Commerce, U.S. Census Bureau, Current Population Survey Food Security Supplement. 

•	 While children are usually shielded from the disrupted eating patterns and reduced food intake that 

characterize very low food security, in 2017 both children and adults experienced instances of very low 

food security in 0.7 percent of households with children (250,000 households), essentially unchanged 

from 0.8 percent in 2016. 

•	 Rates of food insecurity were higher than the national average for the following groups: households 

with incomes near or below the Federal poverty line, all households with children and particularly 

households with children headed by single women or single men, women and men living alone, Blackand Hispanic-headed households, and households in principal cities and nonmetropolitan areas.

•	 The prevalence of food insecurity varied considerably from State to State, ranging from 7.4 percent in 

Hawaii to 17.9 percent in New Mexico in 2015-17. (Data for 3 years were combined to provide more 

reliable State-level statistics.)

•	 The typical (median) food-secure household spent 23 percent more for food than the typical foodinsecure household of the same size and composition. These estimates include food purchases made 

with Supplemental Nutrition Assistance Program (SNAP) benefits.

•	 About 58 percent of food-insecure households in the survey reported that, in the previous month, they 

had participated in one or more of the three largest Federal nutrition assistance programs (SNAP; 

Special Supplemental Nutrition Program for Women, Infants, and Children (WIC); and the National 

School Lunch Program). 

How Was the Study Conducted?

The annual food security survey conducted by the U.S. Census Bureau covered 37,389 households, 

comprising a representative sample of 127 million U.S. households. The survey asked one adult respondent 

per household questions about experiences and behaviors that indicate food insecurity, such as being unable 

to afford balanced meals, cutting the size of meals, or being hungry because of too little money for food. The 

food security status of the household was assigned based on the number of food-insecure conditions reported.

Household Food Security in the 

United States in 2017

Introduction

Since 1995, the U.S. Department of Agriculture has collected information annually on food access 

and adequacy, food spending, and sources of food assistance for the U.S. population. The information is collected in an annual survey, the Food Security Supplement, conducted by the U.S. Census 

Bureau as a supplement to the nationally representative Current Population Survey.1 A major 

impetus for this data collection is to provide information about the prevalence and severity of food 

insecurity in U.S. households. Annual monitoring of food security contributes to the effective operation of the Federal nutrition assistance programs as well as private food assistance programs and 

other government initiatives aimed at reducing food insecurity. Previous reports in the series are 

available on the ERS website.

This report updates the national statistics on food security, household food spending, and the use 

of Federal food and nutrition assistance by food-insecure households, using data collected in the 

December 2017 food security survey—the 23rd annual survey in the Nation’s food security monitoring system. Additional statistics—including the prevalence of food insecurity during the 30 days 

prior to the food security survey, the frequency of food-insecure conditions, and use of food pantries 

and emergency kitchens—are available in the Statistical Supplement to this report (Coleman-Jensen 

et al., 2018).

security measures.

Household Food Security

Food security—access by all people at all times to enough food for an active, healthy life—is one of 

several conditions necessary for a population to be healthy and well nourished. This section provides 

information on food security and food insecurity in U.S. households over the course of the year 

ending in December 2017.

Methods

The statistics presented in this report are based on data collected in the Food Security Supplement 

to the Current Population Survey (CPS) conducted in December 2017. The CPS currently includes 

about 52,000 households and is representative, at State and national levels, of the civilian, noninstitutionalized population of the United States. In December 2017, 37,389 households completed the 

Food Security Supplement; the remaining households were unable or unwilling to do so. Survey 

sample weights were calculated by the U.S. Census Bureau to indicate how many households were 

represented by each household that responded to the survey.2 All statistics in this report were calculated by applying the Food Security Supplement weights to responses by the surveyed households, so 

the statistics are nationally representative. 

Unless otherwise noted, statistical differences described in the text are significant at the 90-percent 

confidence level.3

Household food security statistics presented here are based on a measure of food security calculated 

from responses to a series of questions about conditions and behaviors that characterize households 

when they are having difficulty meeting basic food needs.4 Each question asks whether the condition 

or behavior occurred at any time during the previous 12 months and specifies a lack of money and 

other resources to obtain food as the reason. Voluntary fasting or dieting to lose weight are thereby 

excluded from the measure. The series includes three questions about food conditions of the household as a whole and seven questions about food conditions of adults in the household; if children are 

present, an additional eight questions about their food conditions are included (see box, “Questions 

Used To Assess the Food Security of Households in the CPS Food Security Supplement,” page 3).5

2In 2017, 28.0 percent of households that responded to the monthly December CPS did not complete the Food Security 

Supplement. Reweighting of the Supplement takes into consideration income and other information about households that 

completed the labor-force portion of the survey but not the Food Security Supplement. This corrects, to some extent, biases 

that could result from nonresponse to the Supplement by households that completed only the labor-force part of the survey.

3Standard errors of national-level estimates from 2011 to the present were calculated using balanced repeated replication 

(BRR) methods based on replicate weights computed for the CPS Food Security Supplement by the U.S. Census Bureau. For 

years before 2011, standard errors of national estimates use a design factor of 1.6 based on the complex CPS sample design. 

State-level estimates from 2010 to the present use replicate weights computed for the CPS Food Security Supplement. Before 

2010, standard errors of State-level estimates were calculated using jackknife replication methods with “month in sample” 

groups considered as separate independent samples. This report uses the phrase essentially unchanged to describe differences 

between estimates of a statistic for 2 years that are not statistically significant at the 90-percent confidence level. Standard 

errors of all estimates are available from the authors by request.

4The methods used to measure the extent and severity of food insecurity have been described in a number of studies 

(Hamilton et al., 1997a, 1997b; Andrews et al., 1998; Bickel et al., 1998; Carlson et al., 1999; Bickel et al., 2000; Nord and 

Bickel, 2002). See also the assessment of the measurement methods by a panel of the Committee on National Statistics (National Research Council, 2006). Further details on the development of the measure are provided on the ERS website.

5An official Spanish translation of the food security questions is used in the survey and available on the ERS website. 

ERS assessed the effect of interview language on Hispanics versus non-Hispanics and found no differences in the statistical 

properties of the food security measure (Rabbitt and Coleman-Jensen, 2017).

Questions Used To Assess the Food Security of 

Households in the CPS Food Security Supplement

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

Responses to the 18 food security questions are reported in tables S-5 to S-7 of the Statistical 

Supplement (Coleman-Jensen et al., 2018). The food security status of each interviewed household 

is determined by the number of food-insecure conditions and behaviors the household reports. 

Households are classified as food secure if they report no food-insecure conditions or only one 

or two food-insecure conditions. (Food-insecure conditions are indicated by responses of “often” 

or “sometimes” to questions 1-3 and 11-13, “almost every month” or “some months but not every 

month” to questions 5, 10, and 17, and “yes” to the other questions.) They are classified as food 

insecure if they report three or more food-insecure conditions.6 Households are classified as having 

food-insecure children if they report two or more food-insecure conditions among the children in 

response to questions 11-18.7

Food-insecure households are further classified as having either low food security or very low food 

security.8 The very low food security category identifies households in which the food intake of one 

or more members was reduced and eating patterns disrupted because of insufficient money and other 

resources for food. Households without children are classified as having very low food security if they 

report six or more food-insecure conditions. Households with children age 0-17 are classified as having 

very low food security if they report eight or more food-insecure conditions among adults and/or children (see box, “What Is ‘Very Low Food Security’?” on page 5). 9 They are further classified as having 

very low food security among children if they report five or more food-insecure conditions among the 

children (that is, if they respond affirmatively to five or more of questions 11-18). 

Low and very low food security differ in the extent and character of the adjustments the household 

makes to its eating patterns and food intake. Households classified as having low food security have 

reported multiple indications of food acquisition problems and reduced diet quality, but typically 

have reported few, if any, indications of reduced food intake. Those classified as having very low 

food security have reported multiple indications of reduced food intake and disrupted eating patterns 

due to inadequate resources for food. In most, but not all, households with very low food security,

the survey respondent reported that he or she was hungry at some time during the year but did not 

eat because there was not enough money for food.

6To reduce the survey burden on higher income respondents, households with incomes above 185 percent of the Federal 

poverty line that give no indication of food-access problems on either of two preliminary screening questions are deemed to 

be food secure and are not asked the questions in the food security assessment series. The preliminary screening questions 

asked of all households are as follows:

•	 People do different things when they are running out of money for food in order to make their food or their food 

money go further. In the last 12 months, since December of last year, did you ever run short of money and try to 

make your food or your food money go further?

•	 Which of these statements best describes the food eaten in your household—enough of the kinds of food we 

want to eat, enough but not always the kinds of food we want to eat, sometimes not enough to eat, or often not 

enough to eat?

7Both qualitative and quantitative research studies have suggested that parents’ reports of their children’s food insecurity 

sometimes differed from adolescents’ self-reported food insecurity and that parents were sometimes unaware of the degree to 

which children reduced their own food intake due to household food insecurity (Fram et al., 2011; Nord and Hanson, 2012). 

The extent to which underreporting of children’s food insecurity may exist is unknown (see pp. 9-10 in Coleman-Jensen, 

McFall, and Nord (2013) for a discussion of research on parent-reported and self-reported food insecurity among children). 

8Prior to 2006, households with low food security were described as “food insecure without hunger” and households with 

very low food security were described as “food insecure with hunger.” Changes in these descriptions were made in 2006 at 

the recommendation of the Committee on National Statistics (National Research Council, 2006) in order to distinguish the 

physiological state of hunger from indicators of food availability. The criteria by which households were classified remained 

unchanged. 

9Implications of differences in raw score thresholds for very low food security between households with and without 

children are discussed in Nord and Coleman-Jensen (2014) and Coleman-Jensen, Rabbitt, and Gregory (2017).

Household Food Security in the United States in 2017, ERR-256

Very low food security can be characterized in terms 

of the conditions that households in this category 

reported in the food security survey. Households 

without children classified as having very low food 

security reported six or more food-insecure conditions and households with children reported eight or 

more food-insecure conditions, including conditions 

among both adults and children. Thus, the conditions 

reported by respondents reflect the definition of “very 

low food security”: at times during the year, the food 

intake of household members was reduced and their 

normal eating patterns were disrupted because the 

household lacked money and other resources for 

food. In the 2017 survey, households classified as 

having very low food security (representing an estimated 5.8 million households nationwide) reported 

the following specific conditions:

•	 99 percent reported having worried that their food 

would run out before they got money to buy more.

•	 97 percent reported that the food they bought just 

did not last and they did not have money to get 

more.

•	 95 percent reported that they could not afford to 

eat balanced meals.

•	 96 percent reported that an adult had cut the size 

of meals or skipped meals because there was not 

enough money for food; 88 percent reported that

•	 93 percent reported that they had eaten less 

than they felt they should because there was not 

enough money for food.

•	 68 percent reported that they had been hungry but 

did not eat because they could not afford enough 

food.

•	 48 percent reported having lost weight because 

they did not have enough money for food.

•	 30 percent reported that an adult did not eat 

for a whole day because there was not enough 

money for food; 24 percent reported that this had 

occurred in 3 or more months.

As noted above, all households without children 

classified as having very low food security reported 

at least six of these conditions. The majority of 

households with very low food security, 67 percent, 

reported seven or more food-insecure conditions. 

(Conditions reported by households with children 

were similar to those without children, but the 

reported food-insecure conditions of both adults and 

children were taken into account.)

Prevalence of Food Insecurity—National Conditions and Trends

An estimated 88.2 percent of U.S. households were food secure throughout the entire year in 2017 (fig. 

1, table 1A). In concept, “food secure” means that all household members had access at all times to 

enough food for an active, healthy life (Anderson, 1990).10 The remaining 11.8 percent (15.0 million 

households) were food insecure at some time during the year. That is, they were at times unable to 

acquire adequate food for one or more household members because they had insufficient money and 

other resources for food. A majority of food-insecure households—those classified as having low food 

security (but not very low food security)—avoided substantial reductions or disruptions in food intake, 

in many cases by relying on a few basic foods and reducing variety in their diets. But 4.5 percent (5.8 

million households) had very low food security—that is, they were food insecure to the extent that 

eating patterns of one or more household members were disrupted and their food intake reduced, at 

least some time during the year, because they could not afford enough food. 

Among U.S. households with children under age 18, 84.3 percent were food secure in 2017. The 

remaining 15.7 percent of households with children were food insecure at some time during the year 

(fig. 2, table 1B). This prevalence is essentially unchanged from 16.5 percent in 2016. Parents and 

caregivers often are able to maintain normal or near-normal diets and meal patterns for their children, even when the parents themselves are food insecure. In about half of food-insecure households 

with children in 2017, only adults were food insecure (8.0 percent of households with children). 

However, both children and adults were food insecure in 7.7 percent of households with children (2.9 

million households) in 2017. In 0.7 percent of households with children (250,000 households), food 

insecurity among children was so severe that caregivers reported that children were hungry, skipped 

a meal, or did not eat for a whole day because there was not enough money for food. These households are described as having very low food security among children. In such households, sometimes only older children may experience the more severe effects of food insecurity, while younger 

children are protected from those effects (Coleman-Jensen et al., 2013; Nord, 2009a).

The food security survey is designed to measure food security status at the household level. While it 

is informative to examine the number of persons living in food-insecure households, these statistics 

should be interpreted carefully. Within a food-insecure household, each household member may be 

affected differently by the household’s food insecurity. Some members—particularly young children—

may experience only mild effects or none at all, while adults are more severely affected. It is more 

precise, therefore, to describe these statistics as representing “persons living in food-insecure households” rather than as representing “food-insecure persons.” Similarly, “persons living in households 

with very low food security” is a more precise description than “persons with very low food security.”

10Food security statistics, as operationally measured for this report using survey data, are based on household responses 

to items about whether the household was able to obtain enough food to meet their needs. This operational measure does 

not specifically address whether the household members’ food intake was sufficient for active, healthy lives—the conceptual definition of food security. Nonetheless, research based on other data collections has found survey-based measures of 

food security to be statistically associated with various outcomes involving health, nutrition, and children’s development in 

a manner that generally supports the link between the report’s survey-based measure of food security and the conceptual 

definition of food security (see, for example, Gregory and Coleman-Jensen, 2017; Coleman-Jensen et al., 2013; Nord, 

2009a; Nord and Hopwood, 2007; Nord and Kantor, 2006).

questions in the food security scale. In 2017, these exclusions represented 340,000 households (0.3 percent of all households).

2The food security survey measures food security status at the household level. Not all individuals residing in food-insecure households were 

directly affected by the households’ food insecurity. Similarly, not all individuals in households classified as having very low food security were 

subject to the reductions in food intake and disruptions in eating patterns that characterize this condition. Young children, in particular, are often 

protected from effects of the households’ food insecurity.

In 2017, 40.0 million people lived in food-insecure households (table 1A). They constituted 12.5 

percent of the U.S. civilian noninstitutionalized population and included 27.5 million adults and 12.5 

million children (table 1B). About 6.5 million children (8.9 percent) lived in households in which 1 

or more child was food insecure. About 9.7 million adults (3.9 percent) lived in households with very 

low food security (table 1A), and 540,000 children (0.7 percent) lived in households with very low 

food security among children (table 1B).

Statistical Supplement tables S-2 and S-3 present estimates of the number of people and the number 

of children in households in each food security status and household type (Coleman-Jensen et al., 

2018). 

When interpreting food security statistics in this report, bear in mind that households were classified as having low or very low food security based on their experience of the conditions indicated in 

the module at any time during the previous 12 months. The prevalence of these conditions on any 

given day is far below the corresponding annual prevalence. For example, the prevalence of very low 

food security during the 30 days prior to the survey is 2.6 percent (table S-4) and the prevalence on 

an average day during the 30-day period prior to the December 2017 survey is an estimated 0.7-0.8 

percent of households (0.8 million to 1.0 million households; see box, “When Food Insecurity 

Occurs in U.S. Households, It Is Usually Recurrent But Not Chronic,” on page 11).11 Children, along 

with adults, experienced very low food security in an estimated 40,000 to 44,000 households (0.11 

to 0.12 percent of all U.S. households with children) on an average day during the same period. 

11Average daily prevalence of the various behaviors, experiences, and conditions characterizing very low food security 

is calculated based on the proportion of households reporting the condition at any time during the previous 30 days and the 

average number of days in which the condition occurred. The average daily prevalence for each condition is calculated as the 

product of the 30-day prevalence and the average number of days experienced divided by 30. The ratio of daily prevalence 

to monthly prevalence of the various indicator conditions provides the basis for approximating the average daily prevalence 

of very low food security during the reference 30-day period. The daily rate of very low food security is expressed as a range 

whose lower and upper bounds are based on the minimum and maximum ratio of daily prevalence to 30-day prevalence. See 

table S-9 in the online Statistical Supplement (Coleman-Jensen et al., 2018).

are age 0-17. 

2Food-insecure households are those with low or very low food security among adults or children or both.

3In some food-insecure households with children, only adults were food insecure. Households with food-insecure children are those with low or 

very low food security among children. 

4The food security survey measures food security status at the household level. Not all children residing in food-insecure households were directly 

affected by the households’ food insecurity. Similarly, not all children in households classified as having very low food security among children 

were subject to the reductions in food intake and disruptions in eating patterns that characterize this condition. Young children, in particular, are 

often protected from effects of the households’ food insecurity.

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

When households experience very low food security in 

the United States, the resulting instances of reduced food 

intake and disrupted eating patterns are usually occasional 

or episodic, but not usually chronic. The food security 

measurement methods used in this report are designed 

to register these occasional or episodic occurrences. The 

questions used to assess households’ food security status 

ask whether a condition, experience, or behavior occurred 

at any time in the past 12 months, and households can 

be classified as having very low food security based on a 

single, severe episode during the year. Readers should be 

mindful of this when interpreting food insecurity statistics. 

Analyses of additional information collected in the food 

security survey on how frequently various food-insecure 

conditions occurred during the year, whether they occurred 

during the 30 days prior to the survey, and, if so, in how 

many days provide insight into the frequency and duration 

of food insecurity in U.S. households. These analyses reveal 

that in 2017:

•	 About one-fourth of U.S. households with very low food 

security at any time during the year experienced the 

associated conditions rarely or occasionally—in only 1 

or 2 months of the year. For three-fourths of households, 

the conditions were recurrent, experienced in 3 or more 

months of the year.

•	 For about one-fourth of food-insecure households and 

one-third of those with very low food security, occurrence of the associated conditions was frequent or 

chronic. That is, the conditions occurred often, or in 

almost every month.

•	 On average, households that were food insecure at some 

time during the year were food insecure in 7 months 

during the year. During the 30-day period ending in 

mid-December 2017, 8.0 million households (6.3 percent 

of all households) were food insecure—about 54 percent 

of the number that were food insecure at any time 

during the year (see Statistical Supplement table S-4, 

Coleman-Jensen et al., 2018). 

•	 Similarly, households with very low food security at 

some time during the year experienced the associated 

conditions, on average, in 7 months during the year. 

During the 30-day period ending in mid-December 

2017, 3.3 million households (2.6 percent of all households) had very low food security—about 57 percent of 

the number with very low food security at some time 

during the year (see Statistical Supplement table S-4). 

•	 Most households that had very low food security at 

some time during a month experienced the associated 

conditions in 1 to 7 days of the month. The average 

daily prevalence of very low food security during the 

30-day period ending in mid-December 2017 was 

between 0.8 million and 1.0 million households (0.7 to 

0.8 percent of all households)—about 15 to 18 percent 

of the annual prevalence. 

•	 The daily prevalence of very low food security among 

children during the 30-day period ending in midDecember 2017 was probably between 40,000 and 

44,000 households (0.11 to 0.12 percent of households 

with children)—about 16 to 17 percent of the annual 

prevalence. 

•	 The omission of homeless families and individuals 

from these daily statistics biases the statistics downward, and the bias may be substantial relative to the 

estimates, especially for the most severe conditions.

(Statistical Supplement tables S-7 to S-9 (Coleman-Jensen et 

al., 2018) provide information on how often conditions indicating food insecurity occurred, as reported by respondents 

to the December 2017 Food Security Supplement. See Nord 

et al. (2000) for more information about the frequency of 

food insecurity. See Ryu and Bartfeld (2012) and Wilde et 

al. (2010) for more information about longer term patterns 

of food insecurity.)

From 2016 to 2017, there was a statistically significant decline in the prevalence of food insecurity 

from 12.3 percent to 11.8 percent. Food insecurity was essentially unchanged from 2015 to 2016 

(fig. 3, table 1A). (That is, the difference was not statistically significant.) There was a statistically 

significant decline in food insecurity from 14.0 percent in 2014 to 12.7 percent in 2015. Before that, 

the prevalence of food insecurity was essentially unchanged from 2013 to 2014 and from 2012 to 

2014. That is, the changes were within the range that could have resulted from sampling variation. 

The cumulative decline from 2011 (14.9 percent) to 2014 (14.0 percent) was statistically significant, 

and that downward trend continued through 2017. Over the previous decade, food insecurity had 

increased from 10.7 percent in 2001 to nearly 12 percent in 2004, declined to about 11 percent in 

2005-07, then increased in 2008 (to 14.6 percent), and remained essentially unchanged at that level 

in 2009 and 2010.

There was a statistically significant decline in very low food security from 4.9 percent in 2016 to 

4.5 percent in 2017 (fig. 3, table 1A). Very low food security was essentially unchanged from 2015 

to 2016. The decline in very low food security from 5.6 percent in 2014 to 5.0 percent in 2015 

was statistically significant. Before that, the prevalence of very low food security was essentially 

unchanged from 2011 (5.7 percent) through 2014. The prevalence of very low food security was also 

5.7 percent in 2008 and 2009. In 2010, the prevalence of very low food security had declined to 5.4 

percent. Prior to 2008, the prevalence of very low food security had increased from 3.3 percent in 

2001 to 3.9 percent in 2004, and remained essentially unchanged through 2007.

Prevalence of Food Insecurity by Selected Household Characteristics

The prevalence of food insecurity varied considerably in 2017 among households with different 

demographic and economic characteristics (table 2). Differences in food security across demographic and geographic groups reflect, in part, differences in income across those groups; though no 

adjustment is made for income in the statistics presented in this report, food insecurity was strongly 

associated with income. For example, 36.8 percent of households with annual incomes below the 

official poverty line (household income-to-poverty ratio under 1.00) were food insecure, compared 

with 5.8 percent of those with incomes at or above 185 percent of the poverty line.12

Rates of food insecurity were below the national average of 11.8 percent for married-couple families with children (9.5 percent), households with more than one adult and no children (7.7 percent), 

households with elderly persons (7.9 percent), and elderly living alone (8.6 percent).13 The prevalence of food insecurity was also below the national average for White, non-Hispanic households 

(8.8 percent); households headed by non-Hispanics of other, or multiple, races (9.9 percent); and 

households with incomes above 185 percent of the poverty line (5.8 percent). 

Rates of food insecurity were higher than the national average in 2017 for the following groups: 

•	 All households with children (15.7 percent) 14

•	 Households with children under age 6 (16.4 percent) 

•	 Households with children headed by a single woman (30.3 percent) or a single man (19.7 

percent)15 and other households with children (18.1 percent)

•	 Women living alone (13.9 percent) and men living alone (13.4 percent)

•	 Households headed by Black non-Hispanics (21.8 percent) and Hispanics (18.0 percent)

•	 Households with incomes below 185 percent of the poverty threshold (30.8 percent).

12The Federal poverty line was $24,858 for a family of four (two adults and two children) in 2017.

13“Elderly” in this report refers to persons ages 65 and older.

14About 40 percent of the difference in food insecurity between households with and without children results from a difference in the measures applied to the two types of households. Responses to questions about children as well as adults are 

considered in assessing the food security status of households with children, but for both types of households, a total of three 

indications of food insecurity is required for classification as food insecure. Even with the child-referenced questions omitted 

from the scale, however, in 2017, 13.3 percent of households with children would be classified as food insecure (that is, as 

having food insecurity among adults), compared with 10.1 percent for households without children. Comparisons of very 

low food security are not biased substantially by this measurement issue because a higher threshold is applied to households 

with children, consistent with the larger number of questions taken into consideration (Nord and Coleman-Jensen, 2014). See 

Coleman-Jensen, Rabbitt, and Gregory (2017) for a discussion of a comparable classification method for households with and 

without children. 

15Some households with children headed by a single woman or a single man as classified for these analyses included other 

adults, who may have been parents, siblings, cohabiting partners, adult children, or other relatives of the reference person or 

unrelated roomers or boarders.

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

Across residential classifications, food insecurity was higher than the national average for households 

in principal cities of metropolitan areas (13.8 percent) and in nonmetropolitan (rural) areas (13.3 

percent), and lower for households in suburbs/exurbs and other metropolitan areas outside principal 

cities (9.4 percent).16 Regionally, the prevalence of food insecurity was significantly higher in the 

South (13.4 percent) than in the other three regions. The prevalence of food insecurity was significantly 

higher in the Midwest (11.7 percent) than in the Northeast (9.9 percent) or the West (10.7 percent). The 

prevalence of food insecurity in the Northeast was not statistically different from the West.

The statistics in table 2 show the prevalence of food insecurity across characteristics; these statistics 

can also be used to calculate the share that each group contributes to the population of food-insecure 

households. Among all food-insecure households in 2017, 19.3 percent were female-headed households with children and 15.7 percent were married-couple households with children.17 About 60 

percent of all food-insecure households were adult-only households with no children. Low-income 

households with reported incomes below 185 percent of the poverty threshold made up the majority 

of food-insecure households, 55 percent. Households with reported incomes at or above 185 percent 

of poverty made up about 27 percent of all food-insecure households in 2017. 

The prevalence of very low food security in various types of households followed a pattern similar 

to that observed for food insecurity (table 2). Percentages were lower than the 2017 national average 

of 4.5 percent for married couples with children (2.0 percent); multiple-adult households with 

no children (3.3 percent); households with elderly persons (3.1 percent); elderly living alone (3.7 

percent); White, non-Hispanic households (3.6 percent); households headed by non-Hispanics of 

other, or multiple, races (3.6 percent); households with incomes above 185 percent of the poverty line 

(1.8 percent); households in suburbs and exurbs outside principal cities within metropolitan areas 

(3.6 percent); and households in the Northeast (3.3 percent).

The prevalence of very low food security was significantly higher than the national average (4.5 

percent) for the following groups: 

•	 Households with children headed by a single woman (9.0 percent) 

•	 Women living alone (7.0 percent) and men living alone (6.5 percent)

•	 Black, non-Hispanic households (8.5 percent) and Hispanic households (5.5 percent)

•	 Households with incomes below 185 percent of the poverty line (12.6 percent)

•	 Households located in principal cities (5.4 percent) and outside metropolitan areas (5.4 

percent) 

•	 Households in the South (5.1 percent).

16Revised metropolitan statistical areas (MSAs) and principal cities within them were delineated by the Office of Management and Budget in 2013, based on revised standards developed by the U.S. Census Bureau in collaboration with other Federal agencies. The revised delineations were implemented beginning with the 2014 Current Population Survey Food Security 

Supplement. Food security prevalence statistics by area of residence for 2014 and later are comparable, but are not precisely 

comparable with corresponding statistics from earlier years. Principal cities include the incorporated areas of the largest city 

in each MSA and other cities in the MSA that meet specified criteria based on population size and commuting patterns. 

17For example, the fraction of food-insecure households that are female-headed households with children can be calculated as (2,898/15,018) = 0.193. Similarly, the fraction of food-insecure households that are married-couple households with 

children is (2,361/15,018) = 0.157.

In 7.7 percent of households with children, one or more child was food insecure (table 3).18 Among 

household categories, the percentage of households with food-insecure children was lower in 

married-couple households (4.3 percent); White, non-Hispanic households (5.6 percent); households 

headed by non-Hispanics of other, or multiple, races (5.8 percent); households with incomes above 

185 percent of the poverty line (2.8 percent); and metropolitan households located in suburbs and 

exurbs outside of principal cities (5.9 percent). The percentage of households with food-insecure 

children was higher for female-headed households (16.1 percent); Black, non-Hispanic households 

(13.1 percent); Hispanic households (10.7 percent); low-income households with incomes below 185 

percent of the poverty line (17.9 percent); households in principal cities (9.7 percent); and households 

in nonmetropolitan areas (9.3 percent).

Compared with the prevalence for all households with children (0.7 percent), very low food security among children was less prevalent in married-couple families (0.3 percent) and in households 

located outside principal cities in metropolitan areas (0.4 percent). Very low food security among 

children was more prevalent in households headed by a single woman (1.7 percent) and households 

with incomes below 185 percent of the poverty line (1.9 percent). 

For most population subgroups in 2017, year-to-year changes in the prevalence of food insecurity 

were not statistically significant.19 There was a statistically significant decline in food insecurity for 

households residing outside metropolitan areas (nonmetropolitan) from 15.0 percent in 2016 to 13.3 

percent in 2017 (fig. 4). There were no statistically significant increases in food insecurity.

The prevalence of very low food security (fig. 5) declined significantly from 2016 to 2017 among all 

households with children (from 4.8 percent in 2016 to 4.1 percent in 2017), households with children 

under age 6 (5.0 percent to 4.0 percent), married-couple families with children (2.5 percent to 2.0 

percent), female-headed families with children (10.5 percent to 9.0 percent), men living alone (7.5 

percent to 6.5 percent), and households living in nonmetropolitan areas (6.6 percent to 5.4 percent). 

There were no statistically significant increases in very low food security.

Prevalence of Food Insecurity by State 

The prevalence of food insecurity varies considerably from State to State. In addition to householdlevel characteristics such as income, employment, and household structure, the prevalence of food 

insecurity is also affected by State-level characteristics such as average wages, cost of housing, 

unemployment and State-level policies that affect access to unemployment insurance, the State 

Earned Income Tax Credit, and access to/participation in nutrition assistance programs (Bartfeld et 

al., 2006; Bartfeld and Men, 2017). Prevalence rates for 3 years, 2015-17, were averaged to provide 

more reliable statistics at the State level (table 4). Estimated prevalence rates of food insecurity 

during this 3-year period ranged from 7.4 percent in Hawaii to 17.9 percent in New Mexico; estimated prevalence rates of very low food security ranged from 2.9 percent in Hawaii to 7.1 percent in 

Alabama and Louisiana.20

18Households are classified as having food insecurity among children if they report two or more food-insecure conditions 

among children in response to questions 11-18 in box on page 3.

19Estimates of food insecurity and very low food security for 2016 were published in Household Food Security in the 

United States in 2016 (Coleman-Jensen et al., 2017).

NA = Not reported; fewer than 10 households in the survey with this characteristic had very low food security among children.

1Totals exclude households for which food security status is unknown because they did not give a valid response to any of the questions in the 

food security scale. In 2017, these exclusions represented 109,000 households with children (0.3 percent of all households with children). 

2Food-insecure households are those with low or very low food security among adults or children or both.

3In some food-insecure households with children, only adults were food insecure. Households with food-insecure children are those with low or 

very low food security among children.

4Households with children in complex living arrangements, e.g., children of other relatives or unrelated roommate or boarder.

5Hispanics may be of any race. 

6Metropolitan area residence is based on 2013 Office of Management and Budget delineation. Prevalence rates by area of residence are comparable with those for 2014 and later but are not precisely comparable with those of earlier years. 

7Households within incorporated areas of the largest cities in each metropolitan area. Residence inside or outside of principal cities is not identified for about 14 percent of households with children in metropolitan statistical areas.

The margin of error for State food insecurity rates should be considered when interpreting these 

statistics, especially when comparing prevalence rates across States. The margin of error reflects 

sampling variation—the uncertainty associated with estimates that are based on information from 

a limited number of households in each State. The margins of error presented in table 4 indicate 

the range (above or below the estimated prevalence rate) that is 90 percent likely to include the true 

prevalence rate. For example, considering the margins of error, it is not certain that the prevalence 

of very low food security was higher in Alabama and Louisiana than in the States with the next nine 

highest prevalence rates.

Taking into account margins of error of the State and U.S. estimates, the prevalence of food insecurity was higher (i.e., statistically significantly higher) than the national average in 11 States (AL, AR, 

IN, LA, MS, NC, NM, OH, OK, TX, and WV) and lower than the national average in 15 States (CA, 

CO, HI, IA, MA, MD, MN, ND, NH, NJ, NY, VA, VT, WA, and WI).21 In the remaining 24 States 

and the District of Columbia, differences from the national average were not statistically significant. 

The prevalence of very low food security was higher than the national average in 12 States (AL, AR, 

LA, ME, MI, MS, NM, OH, OK, TN, TX, and WV), lower than the national average in 13 States 

(AK, CA, DE, FL, HI, MA, ND, NH, NJ, NY, PA, VT, and WI), and not significantly different from 

the national average in 25 States and the District of Columbia.

State-level rates of food insecurity and very low food security for 2015-17 are compared with 

2012-14 and 2005-07 averages in table 5. The prevalence rates for the immediately preceding 3-year 

period, 2012-14 are from Household Food Security in the United States in 2014 (Coleman-Jensen et 

al., 2015). The 2005-07 rates are from Household Food Security in the United States, 2007 (Nord 

et al., 2008) and are presented as a baseline to assess changes in State-level food security conditions 

over the past decade.22

There was a statistically significant percentage-point increase (5.6) in the prevalence of food insecurity from 2012-14 to 2015-17 in 1 State (NM), while food insecurity declined significantly in 18 

States (AZ, CA, CO, FL, GA, HI, ID, MO, MS, NJ, NV, NY, OH, OR, TN, TX, VT, and WA) and 

the District of Columbia (table 5). During the same period, the prevalence of very low food security increased significantly in 1 State (NM) and declined significantly in 12 States (CA, CO, FL, 

GA, HI, MO, NH, NJ, NY, OH, VT, and WA). There was a statistically significant percentagepoint increase in the prevalence of food insecurity from 2005-07 to 2015-17 in 18 States, with no 

statistically significant declines. The prevalence of very low food security increased significantly 

from 2005-07 to 2015-17 in 19 States, with no statistically significant declines. Changes not 

marked as statistically significant (*) in table 5 were within ranges that could have resulted from 

sampling variation (that is, a non-zero difference between sample estimates, based on the households that happen to be chosen for the sample, which is consistent with no actual change in food 

security in the State’s general population). 

21Standard error of difference assumes that there is no correlation between national and individual State estimates.

22Prevalence rates for 1996-98 reported in Prevalence of Food Insecurity and Hunger, by State, 1996-1998 (Nord et al., 

1999) are not directly comparable with the rates reported here because of differences in screening procedures in the CPS 

Food Security Supplements from 1995 to 1998. Statistics for 1996-98, adjusted to be comparable with those for recent years, 

are presented in Statistical Supplement to Food Security in the United States in 2010, table S-4. Standard errors of State-level 

estimates for 2005-07 were calculated using jackknife replication methods with “month-in-sample” groups considered as 

separate independent samples (see Nord et al., 1999).

Household Spending on Food

This section provides information on how much households spent on food, as reported in the 

December 2017 Food Security Supplement. Food insecurity is a condition that arises from lack of 

money and other resources to acquire food. In most households, the majority of food consumed by 

household members is purchased, either from supermarkets or grocery stores, to be prepared and 

eaten at home; some food also comes from cafeterias, restaurants, or vending machines to be eaten 

outside the home. The amount of money a household spends on food thus indicates how adequately 

the household is meeting its food needs.23 When a household reduces food spending below some 

minimum level, such as USDA’s Thrifty Food Plan, because of constrained resources, disrupted 

eating patterns and reduced food intake may result. 

Methods

The household food expenditure statistics in this report are based on usual weekly spending for 

food, as reported by respondents after reflecting on the household’s actual food spending during the 

previous week. Respondents were first asked to report the amounts of money their households had 

spent on food in the week prior to the interview, including any purchases made with SNAP benefits 

(formerly called food stamps) at:

•	 supermarkets and grocery stores; 

•	 stores other than supermarkets and grocery stores, such as meat markets, produce stands, 

bakeries, warehouse clubs, and convenience stores;

•	 restaurants, fast-food places, cafeterias, and vending machines; and

•	 “...any other kind of place.”24

Total spending for food, based on responses to this series of questions, was verified with the respondent, and the respondent was then asked how much the household usually spent on food during a 

week.25 ERS analyses have shown that usual food expenditures estimated from data collected by 

this method were consistent with estimates from the Consumer Expenditure Survey (CES)—the 

23Food spending is only an indirect indicator of food consumption. It understates food consumption in households that receive food from in-kind programs, such as the National School Lunch and School Breakfast Programs, WIC, meal programs 

for children in childcare and for the elderly, and private charitable organizations. Purchases with SNAP benefits, however, are 

counted as food spending in the CPS Food Security Supplement. Food spending also understates food consumption in households that acquire a substantial part of their food supply through gardening, hunting, or fishing, as well as in households that 

obtain groceries from friends or relatives or eat more meals at friends’ or relatives’ homes than they provide to friends or relatives. Food spending also understates food consumption in geographical areas with relatively low food prices and overstates 

consumption in areas with relatively high food prices.

24For spending in the first two categories of stores, respondents were also asked how much of the amount was for “nonfood items such as pet food, paper products, alcohol, detergents, or cleaning supplies.” These amounts are subtracted from 

total spending at each of these stores to arrive at spending for food.

25Beginning with the 2015 Current Population Survey Food Security Supplement, food-spending amounts are categorized 

in public-use data. Categorizing the dollar amounts reduces the risk of disclosure and is now standard for data collected by 

the U.S. Census Bureau. ERS analysis suggests this change has little effect on the estimates of median food spending reported 

here. The tables presented in this section are based on the categorical food-spending data and are comparable to the 2016 estimates but are not precisely comparable with estimates published in prior annual food security reports. Changes in food spending from 2016 described in the text are based on comparable estimates of 2016 categorical food-spending data published in 

Coleman-Jensen et al. (2017). 
24

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

principal source of data on U.S. household expenditures for goods and services (Oliveira and Rose, 

1996; Nord, 2009b). 

Food spending was adjusted for household size and composition in two ways. First, we divided 

each household’s usual weekly food expenditure by the number of household members, yielding 

the “usual weekly food spending per person” for that household. The second adjustment accounts 

more precisely for the different food needs of households by comparing each household’s usual food 

spending to the estimated cost of the Thrifty Food Plan for that household in December 2017.26

The Thrifty Food Plan (TFP)—developed by USDA—serves as a national standard for a nutritious, minimal-cost diet. It represents a set of “market baskets” of food that people in specific age 

and gender categories could consume at home to maintain a healthful diet that meets current dietary 

standards, taking into account the food consumption patterns of U.S. households (U.S. Department 

of Agriculture, Center for Nutrition Policy and Promotion, 2007).27 Each household’s reported usual 

weekly food spending was divided by the household-specific cost of the TFP, based on the age- and 

gender-specific cost of the TFP for each household member and the number of persons in the household (U.S. Department of Agriculture, Center for Nutrition Policy and Promotion, 2018).28

The medians of each of the two food-spending measures (spending per person per week and 

spending relative to the cost of the TFP) were estimated at the national level and for households 

in various categories. Medians are reported rather than averages (means) because medians are not 

unduly affected by the few unexpectedly high values of usual food spending that are believed to be 

reporting or data entry errors. Thus, the median better reflects what a typical household spent. 

About 6.8 percent of households interviewed in the CPS Food Security Supplement did not respond 

to the food-spending questions (or reported zero usual food spending) and were excluded from 

the analysis. As a result, the total number of households represented in tables 6 and 7 is somewhat 

smaller than that in tables 1 and 2, and food-spending estimates may not be fully representative of 

all households in the United States.29

Food Expenditures by Selected Household Characteristics

In 2017, the typical U.S. household spent $50.00 per person each week for food (table 6). Median 

household food spending relative to the cost of the TFP—which adjusts for food price inflation and 

adjusts more precisely for the food needs of persons in different age-gender categories—was 1.24, 

essentially unchanged from 1.22 in 2016 (Coleman-Jensen et al., 2017). That is, in 2017, the typical 

household spent 24 percent more on food than the cost of the TFP for that household. 

26The cost of the TFP is revised each month to account for inflation in food prices. For this report, TFP costs are estimated 

by ERS separately for Alaska and Hawaii, using adjustment factors calculated from USDA’s TFP costs for those States for 

the second half of 2017. USDA’s TFP costs for Alaska and Hawaii are available on USDA’s Center for Nutrition Policy and 

Promotion website. 

27The TFP, in addition to its use as a research tool, is used as a basis for setting the maximum SNAP benefit amounts. 

28The cost of a TFP for a household is calculated under the assumption that all household members purchase and prepare 

food together. 

29Households that were unable or unwilling to report food spending were less likely to be food insecure than those that 

did report food spending (8.2 percent compared with 12.1 percent). Food spending may, therefore, be slightly underestimated 

from these data.

Households with children under age 18 generally spent less for food, relative to the household cost 

of the TFP, than those without children. The typical household with children spent 12 percent more 

than the cost of the TFP on food, while the typical household with no children spent 32 percent 

more. Median household food expenditures relative to the cost of the TFP were lower for households 

with children headed by single women (1.04) and single men (1.04) than for married couples with 

children (1.17). Median food expenditure relative to the cost of the TFP was highest for men living 

alone (1.56).

Median food expenditures relative to the cost of the TFP were lower for Black non-Hispanic (1.11) 

and Hispanic households (1.13) than for White non-Hispanic households (1.32). This pattern is 

consistent with the lower average incomes and higher prevalence rates of food insecurity for these 

racial and ethnic minorities.

As expected, households with higher incomes spent more money on food than lower income households.30 The typical household with income below the poverty line spent about 2 percent less than 

the cost of the TFP, while the typical household with income above 185 percent of the poverty line 

spent 39 percent more than the cost of the TFP. Sub-TFP food spending may be inadequate since the 

TFP was designed to be a minimal-cost nutritious diet. 

Median food spending relative to the cost of the TFP was lower for households in nonmetropolitan 

areas (1.13) than for those inside metropolitan statistical areas (1.28). Regionally, median spending 

on food relative to the cost of the TFP was lower in the Midwest (1.19) and South (1.20) than in the 

West (1.29) and Northeast (1.32).

Food Expenditures and Household Food Security

Food-secure households typically spent more on food than did food-insecure households. Median 

food spending relative to the cost of the TFP was 1.28 among food-secure households, compared 

with 1.04 among food-insecure households (table 7). Taking into account estimated food need, the 

median food-secure household spent approximately 23 percent more for food than the median foodinsecure household in 2017 (estimated as 1.28/1.04=1.23).31

30However, food spending does not rise proportionately with income, so high-income households actually spend a smaller 

proportion of their income on food than low-income households.

31The pattern of higher food spending among food-secure households compared with food-insecure households was also 

found in USDA’s National Household Food Acquisition and Purchase Survey (FoodAPS) data (Tiehen et al., 2017).

Federal Food and Nutrition Assistance Programs and 

Food Security

Households with limited resources use a variety of methods to help meet their food needs. Some 

participate in Federal food and nutrition assistance programs or obtain food from emergency providers 

in their communities to supplement the food they purchase. Households that turn to Federal and 

community food and nutrition assistance programs typically do so because they are having difficulty 

meeting their food needs. The use of such programs by low-income households provides insight into 

the extent of these households’ difficulties in obtaining enough food. The relationship between food 

security status and use of food and nutrition assistance programs also provides insight into the ways 

low-income households cope with difficulties in acquiring adequate food.

This section presents information about the food security status of households that participated 

in the three largest Federal food and nutrition assistance programs: SNAP, the National School 

Lunch Program, and WIC (see box, “Federal Food and Nutrition Assistance Programs,” p. 29). It 

also provides information about the extent to which food-insecure households participated in these 

programs. Total participation in the Federal food and nutrition assistance programs, participation 

rates of eligible households in those programs, and characteristics of participants in the programs are 

not described in this report. Extensive information on those topics is available from USDA’s Food 

and Nutrition Service (FNS).32

Statistical Supplement tables S-11 to S-16 provide information on food spending by participants 

and low-income nonparticipants in selected Federal and community food and nutrition assistance 

programs and about the extent to which households obtained assistance from community food 

pantries and emergency kitchens (Coleman-Jensen et al., 2018).

Methods

The December 2017 CPS Food Security Supplement included questions about the use of Federal 

food and nutrition assistance programs. All households with reported annual incomes below 185 

percent of the Federal poverty threshold were asked these questions. To minimize respondent 

burden, households with annual incomes above that range were not asked the questions unless they 

indicated some level of difficulty in meeting their food needs on the first of the two preliminary 

screener questions asked of all households (listed in footnote 6, p. 4). The questions analyzed in this 

section are:

•	 During the past 12 months...did anyone in this household get SNAP or food stamp benefits?33

Households that responded affirmatively were then asked:

•	 In which months were SNAP benefits received?

•	 On what date did you last receive them?

32Additional research findings on the operation and effectiveness of these programs are available from the ERS website.

33The Food Stamp Program was renamed the Supplemental Nutrition Assistance Program (SNAP) in October 2008. Both 

names were mentioned in the survey question, as well as the State’s name for the program in States that used a different name. 
29

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

The U.S. Department of Agriculture’s Food and Nutrition Service (FNS) administers 15 

domestic food and nutrition assistance programs. The three largest programs are:

•	 The Supplemental Nutrition Assistance Program (SNAP), formerly the Food Stamp 

Program. The program provides monthly benefits to eligible low-income households to 

purchase food items at SNAP-authorized retailers. SNAP is available to all individuals 

who meet financial and nonfinancial eligibility criteria. In an average month of fiscal year 

2017 (October 1, 2016, through September 30, 2017), SNAP provided benefits to nearly 

42.2 million people in the United States (about 13 percent of individuals). The average 

benefit was about $126 per person per month, and Federal expenditures for the program 

were nearly $68 billion that year. 

•	 The National School Lunch Program. The program operates in over 100,000 public and 

nonprofit private schools and residential childcare institutions. All meals served under the 

program receive Federal subsidies, and free or reduced-price lunches are available to lowincome students. In fiscal year 2017, the program provided lunches to an average of 30.0 

million children each school day. Two-thirds (67 percent) of the lunches served in 2017 

were free, and an additional 7 percent were provided at reduced prices. 

•	 The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The 

program is a federally funded preventive nutrition program that provides grants to States to 

support distribution of supplemental foods, healthcare referrals, and nutrition education for 

low-income pregnant, breastfeeding, and nonbreastfeeding postpartum women; for infants 

in low-income families; and for children in low-income families who are younger than age 

5 and who are found to be at nutritional risk. Most State WIC agencies provide vouchers 

that participants use to acquire supplemental food packages at authorized food stores. In 

fiscal year 2017, WIC served 7.3 million participants per month at an average monthly cost 

for food (after rebates to WIC from manufacturers) of about $41 per person. 

(For more information, see Oliveira, 2018.)

Federal Food and Nutrition Assistance Programs

Information from the three questions was used to identify households that received SNAP benefits in 

the 30 days prior to the survey.34

Additional questions about Federal food and nutrition assistance programs analyzed here are: 

•	 During the past 30 days, did any children in the household...receive free or reduced-price 

lunches at school? (Only households with children between the ages of 5 and 18 were asked 

this question.)

•	 During the past 30 days, did any women or children in this household get food through the 

WIC program? (Only households with a child under age 5 or a woman age 15-45 were asked 

this question.)

34The CPS household does not always match the SNAP unit. In some households, only some members are eligible for 

SNAP (Czajka et al., 2012; Scherpf et al., 2015). 
30

Household Food Security in the United States in 2017, ERR-256

USDA, Economic Research Service

Prevalence rates of food security, food insecurity, and very low food security were calculated 

for households reporting use of each food and nutrition assistance program and for comparison 

groups of nonparticipating households with incomes and household compositions similar to those 

of food assistance recipients. Statistics for participating households excluded households with 

annual incomes above the ranges specified for the comparison groups.35 The proportions of foodinsecure households participating in each of the three largest Federal food and nutrition assistance 

programs—SNAP, the National School Lunch Program, and WIC—were calculated, as well as the 

proportion that participated in any of the three programs. These analyses were restricted to households with annual incomes below 185 percent of the poverty line because most households with 

incomes above this range were not asked whether they participated in these programs.

Food Security of Households That Received Food and Nutrition Assistance

The relationship between food security and the use of food and nutrition assistance programs is 

complex. There are reasons to expect that households that report using food and nutrition assistance programs in a one-time survey can either be more food secure or less food secure than lowincome households not using those programs. Since the programs provide food and other resources 

to reduce the severity of food insecurity, households are expected to be more food secure after 

receiving program benefits than they were before. On the other hand, it is the more food-insecure 

households—those having greater difficulty meeting their food needs—that seek assistance from the 

programs.36 In 2017, an estimated 50.1 percent of households that received SNAP benefits were food 

insecure, as were 41.7 percent of households that received free or reduced-price school lunches and 

38.2 percent of those that received WIC benefits (table 8). 

The prevalence of very low food security among households participating in SNAP was more than 

double that of nonparticipating households in the same low-income range (22.0 percent versus 9.8 

percent). For households that received free or reduced-price school lunches, the prevalence of very 

low food security was also double that of nonparticipating households with school-age children in 

the same income range (13.2 percent versus 6.6 percent). 

A possible complicating factor in interpreting table 8 is that food insecurity was measured over a 

12-month period. An episode of food insecurity may have occurred at a different time during the 

year than the use of a specific food and nutrition assistance program. A similar tabulation using 

a 30-day measure of food insecurity largely overcomes this potential problem because measured 

food insecurity and reported use of food and nutrition assistance programs are more likely to refer 

to concurrent conditions when both are referenced to the previous 30 days. That tabulation shows 

patterns of food insecurity and the use of food and nutrition assistance programs that are similar to 

those in table 8, although 30-day food insecurity prevalence rates were lower than the corresponding 

12-month rates (see Statistical Supplement table S-15, Coleman-Jensen et al., 2018).

35Some program participants reported annual incomes that were higher than 12 times the program eligibility criteria, which 

are based on monthly income (relative to poverty). They may have had monthly incomes below the monthly eligibility threshold 

during part of the year, or subfamilies within the household may have had incomes low enough to have been eligible.

36This “self-selection” effect is evident in the association between food security and food program participation observed 

in the food security survey. Participating households were less food secure than similar nonparticipating households. More 

complex analysis, using methods to account for this self-targeting, is required to assess the extent to which the programs 

improve food security (see Gregory et al., 2015, for a review of this literature and these methods; also see Mabli et al., 2013; 

Nord, 2013; Nord, 2012; Nord and Prell, 2011; Ratcliffe and McKernan, 2011; Nord and Golla, 2009; Yen et al., 2008; Wilde 

and Nord, 2005; Gundersen and Oliveira, 2001; Gundersen and Gruber, 2001; Nelson et al., 1998). Overall, these studies find 

that SNAP improves food security.

Participation in Federal Food and Nutrition Assistance Programs 

by Food-Insecure Households

About 58 percent of food-insecure households reported receiving assistance from one or more of the 

three largest Federal food and nutrition assistance programs during the month prior to the December 

2017 food security survey (table 9). SNAP provided assistance to 43.1 percent of food-insecure 

households; children in 30.5 percent of food-insecure households received free or reduced-price 

school lunches; and women or children in 9.4 percent of food-insecure households received WIC 

food vouchers.37 An estimated 56.3 percent of households classified as having very low food security reported participating in one or more of the three largest Federal food and nutrition assistance 

programs, with the largest share (46.5 percent) participating in SNAP.38

37These statistics may be biased downward. It is known from comparisons between household survey data and administrative records that food program participation is underreported by household survey respondents, including those in the 

CPS (Meyer and George, 2011; Parker, 2011; Meyer et al., 2009). This is probably true for food-insecure households as well, 

although the extent of underreporting by these households is not known. Statistics are based on the subsample of households 

with annual incomes below 185 percent of the poverty line. Not all of these households were eligible for certain programs. 

(For example, many households without pregnant women or children and with incomes above 130 percent of poverty would 

not have been eligible for any of the programs.)

38The statistics in table 9 were also calculated for households that were food insecure during the 30-day period prior to the 

survey. In principle, that analysis is preferable because food security status and use of programs are more certainly contemporaneous than when food insecurity is assessed over a 12-month period. However, the results differed only slightly from those 

in table 9 and are not presented in a separate table. In 2017, an estimated 59.6 percent of households that were food insecure 

during the 30-day period prior to the survey participated in SNAP, free or reduced-price school lunch, or WIC during that 

same period. Among households that experienced very low food security in the 30-day period prior to the survey, 55.9 percent 

participated in SNAP, free or reduced-price school lunch, or WIC during that same period.

1Analysis is restricted to households with annual incomes less than 185 percent of the poverty line because most households 

with incomes above that range were not asked whether they participated in food assistance programs.

2These statistics understate the extent of food and nutrition program participation because program participation is 

underreported by household survey respondents, see footnote 37.
