This page includes resources on the two slightly different versions of the U.S. (federal) poverty measure: the poverty thresholds and the poverty guidelines.
- The poverty thresholds are the original version of the federal poverty measure. They are updated each year by the Census Bureau. The thresholds are used mainly for statistical purposes — e.g., preparing estimates of the number of Americans in poverty each year.
- The poverty guidelines are the other version of the federal poverty measure. They are issued each year in the Federal Register by the Department of Health and Human Services. The guidelines are a simplification of the poverty thresholds for use for administrative purposes — e.g., determining financial eligibility for certain federal programs.
Key differences between the poverty thresholds and the poverty guidelines are outlined on our Frequently Asked Questions (FAQs>) page. See also the discussion of this topic on the Institute for Research on Poverty’s web site.
Background Paper on the Poverty Guidelines
Besides presenting the guidelines for a particular year, this article is a background paper on the poverty guidelines. It describes the differences between the poverty guidelines and poverty thresholds, lists a number of federal programs that use the guidelines as an eligibility criterion, and shows how the guidelines are calculated from the thresholds each year.
Programs That Do — and Don’t — Use the Poverty Guidelines
The HHS poverty guidelines, or percentage multiples of them (such as 125 percent, 150 percent, or 185 percent), are used as an eligibility criterion by a number of federal programs, including those listed below. For examples of major means-tested programs that do not use the poverty guidelines, see the end of this response.
- Corporation for National and Community Service:
- Foster Grandparent Program
- Senior Companion Program
- Department of Agriculture:
- Child and Adult Care Food Program (for free and reduced-price meals only)
- Expanded Food and Nutrition Education Program
- National School Lunch Program (for free and reduced-price meals only)
- School Breakfast Program (for free and reduced-price meals only)
- Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)
- Supplemental Nutrition Assistance Program (SNAP) (formerly Food Stamp Program)
- Department of Energy:
- Weatherization Assistance for Low-Income Persons
- Department of Health and Human Services:
- AIDS Drug Assistance Program
- Assets for Independence Demonstration Program
- Children’s Health Insurance Program
- Community Health Centers
- Community Services Block Grant
- Family Planning Services
- Head Start
- Health Careers Opportunity Program
- Health Professions Student Loans — Loans for Disadvantaged Students
- Hill-Burton Uncompensated Services Program
- Job Opportunities for Low-Income Individuals
- Low-Income Home Energy Assistance Program (LIHEAP)
- Low Income Household Water Assistance Program (LIHWAP)
- Medicare – Prescription Drug Coverage (subsidized portion only)
- Migrant Health Centers
- PARTS of Medicaid (31 percent of eligibles in Fiscal Year 2004)
- Scholarships for Health Professions Students from Disadvantaged Backgrounds
- Department of Labor:
- Job Corps
- National Farmworker Jobs Program
- Senior Community Service Employment Program
- Workforce Investment Act Youth Activities
- Department of the Treasury:
- Low-Income Taxpayer Clinics
- Legal Services Corporation:
- Legal Services for the Poor
Most of these programs are non-open-ended programs — that is, programs for which a fixed amount of money is appropriated each year. A few open-ended or “entitlement” programs that use the poverty guidelines for eligibility are the Supplemental Nutrition Assistance Program (formerly Food Stamps), the National School Lunch Program, certain parts of Medicaid, and the subsidized portion of Medicare – Prescription Drug Coverage.
Some state and local governments have chosen to use the federal poverty guidelines in some of their own programs and activities. Examples include financial guidelines for child support enforcement and determination of legal indigence for court purposes. Some private companies (such as utilities, telephone companies, and pharmaceutical companies) and some charitable agencies also use the guidelines in setting eligibility for their services to low-income persons.
Major means-tested programs that do not use the poverty guidelines in determining eligibility include the following:
- Supplemental Security Income (SSI)
- Earned Income Tax Credit (EITC)
- State/local-funded General Assistance (in most cases)
- Some parts of Medicaid
- Section 8 low-income housing assistance
- Low-rent public housing
The Official Federal Statistical Definition of Poverty
Statistical Policy Directive No. 14, “Definition of Poverty for Statistical Purposes” ( Federal Register, Vol. 43, No. 87, May 4, 1978, p. 19269)
In August 1969, the U.S. Bureau of the Budget (the predecessor of the U.S. Office of Management and Budget) designated the Census Bureau’s poverty thresholds as the federal government’s official statistical definition of poverty. This directive is the latest version of the document embodying that designation.

Research on Alternative Approaches to Poverty Measurement
Recommendation of the Subcommittee on Updating the Poverty Threshold, August 2, 1973.
Memorandum from Milo B. Sunderhauf, Statistical Policy Division, Office of Management and Budget, to Robert Raynsford, Office of Management and Budget — Subject: Recommendations of the Subcommittee on Updating the Poverty Threshold. (Note that Mollie Orshansky was one of the members of this Subcommittee.)
Consolidated Report of Subcommittee Chairmen: Review of Poverty Statistics, September 4, 1973
Memorandum from Bette Mahoney, Chairman, Subcommittee on Measurement of Non-Cash Income, Milo B. Sunderhauf, Chairman, Subcommittee on Updating the Poverty Threshold, and Murray S. Weitzman, Chairman, Subcommittee on Measurement of Cash Income, THRU Robert W. Raynsford, Statistical Policy Division, Office of Management and Budget, to Paul F. Krueger — Subject: Consolidated Report of Subcommittee Chairmen: Review of Poverty Statistics.
In 1973, these subcommittees conducted a review of the federal statistics in these areas at the request of the Office of Management and Budget's Statistical Policy Division. This review was significant because many of the professionals who conducted it had been working with poverty and income concepts for years; they were familiar not only with these concepts themselves but also with the contexts in which they had been developed and (in a number of cases) with what had been done before the existing concepts were put in place. The recommendations of this review were not extensively publicized. In addition, they seem to have been eclipsed several years later by the Measure of Poverty report.
U.S. Department of Health, Education, and Welfare, The Measure of Poverty: A Report to Congress as Mandated by The Education Amendments of 1974, Washington, D.C., U.S. Government Printing Office, April 1976
This report thoroughly explored the issues involved in developing and revising poverty measures, gathering extensive supporting information that was presented in the report itself and in 17 Technical Papers. The report did not recommend specific changes in the current poverty measure. The report and the technical papers are now available on the Census Bureau’s Web site.

Beginning in 2004, the U.S. Department of Commerce and the U.S. Department of Health and Human Services (ASPE) provided funding for a series of seminars to explore the limitations of the current federal poverty measure and to identify alternative approaches for measuring the material well-being of low-income Americans. Seminar participants included most of the senior government officials responsible for the relevant surveys, as well as academics broadly representative of different disciplines and political orientations. This paper provides a description of the seminar project. Working papers and summaries of individual seminars are available .

Successive unofficial poverty lines developed as absolute poverty lines show a pattern of rising in real terms over time as the real income of the general population rises; this phenomenon has been termed “the income elasticity of the poverty line.” This 78-page paper assembles extensive historical evidence of this phenomenon not only from the U.S. but also from the three other countries named.

As indicated by the title, this paper applies unofficial 1949 and 1959 definitions of poverty to income data for the 1947-1963 period, yielding poverty population estimates for those years. These estimates were included in the subchapter on poverty published in Historical Statistics of the United States (Millennial Edition) (2006). The paper also withdraws an unpublished 1985 set of poverty population estimates by the author which applied a 1960s definition of poverty--the current official definition--to income data for 1947-1959. The paper argues that it was inappropriate to apply a 1960s definition of poverty to income data for the 1940s and 1950s.
