Poverty thresholds and poverty guidelines are two different federal measures — and the “three times food cost” was calculated once, for the 1963 base year
Census issues poverty thresholds for statistics; HHS issues guidelines for eligibility. OMB has never issued either. The multiply-by-three was done once, for the 1963 base year. Retrieved 2026-09-28.
Two measures, two agencies, two jobs
There are two of them, and they are not interchangeable. “Poverty thresholds are used for calculating all official poverty population statistics” — issued by the Census Bureau.[1]
“The poverty guidelines are a simplified version of the federal poverty thresholds used for administrative purposes - for instance, determining financial eligibility for certain federal programs.” These are issued by the Department of Health and Human Services, which “The Department of Health and Human Services (HHS) is required to issue the guidelines at least once every 12 months according to Section 673(2) of the Omnibus Budget Reconciliation Act (OBRA) of 1981 (42 U.S.C. 9902(2)).”[1]
So “what is the federal poverty level” is under-specified unless the context already says which measure is meant. Official poverty statistics use the thresholds. Program eligibility uses the guidelines — where a program uses them at all, which many do not (below).[1]
Worth noting: the phrase “federal poverty level” does not appear anywhere in this FAQ, and neither does the abbreviation “FPL” — we searched the full fetched text for both. That is a fact about this page, not about usage elsewhere or about what the agency calls these measures in other documents.[1]
They are shaped differently, and one of them has geography
Thresholds: “Detailed (48-cell) matrix of thresholds varies by family size, number of children, and, for 1- & 2-person units, whether or not elderly.” And crucially — “There is no geographic variation; the same figures are used for all 50 states and D.C.”[1]
Guidelines: “Guidelines vary by family size. In addition, there is one set of figures for the 48 contiguous states and D.C.; one set for Alaska; and one set for Hawaii.” So of these two measures, geography appears only on the administrative side, not the statistical one.[1]
Even the rounding differs. Thresholds are “Rounded to the nearest dollar”; guidelines are “Rounded to various multiples of $10 - may end only in zero”.[1]
And they are updated by different mechanics. Thresholds: “The 48-cell matrix is updated each year from the 1978 threshold matrix using the CPI-U.” “The preliminary weighted average thresholds are updated from the previous year’s final weighted average thresholds using the CPI-U.” “The final weighted average thresholds are calculated from the current year’s 48-cell matrix using family weighting figures from the Current Population Survey’s Annual Social and Economic Supplement.” Guidelines: “Guidelines are updated from the latest published (final) weighted average poverty thresholds using the CPI-U. (Figures are rounded, and differences between adjacent-family-size figures are equalized.)”[1]
The thresholds also come out twice. “The Census Bureau typically issues preliminary poverty thresholds in January, and final poverty thresholds in September of the year after the year for which poverty is measured.” So “the 2025 thresholds” can mean either the January preliminary set or the September final set, and the guidelines are built from the final ones.[1]
OMB has never issued the thresholds or the guidelines
Statutes refer to “the official poverty line defined by the Office of Management and Budget,” which makes it sound as though OMB publishes a number. It does not. “OMB has never issued either the poverty thresholds or the poverty guidelines.”[1]
What happened was a single act in 1969: “the role of the Office of Management and Budget (OMB) vis-a-vis the poverty line was limited to this one-time designation of the poverty thresholds as the official federal statistical definition of poverty”[1]
ASPE even supplies the wording to use instead when a statute needs to point at the guidelines — “the poverty guidelines updated periodically in the Federal Register by the U.S. Department of Health and Human Services under the authority of 42 U.S.C. 9902(2)”.[1]
The “times three” was done once, for the 1963 base year
“The poverty thresholds were originally developed in 1963-1964 by Mollie Orshansky of the Social Security Administration.”[1]
The reasoning behind the multiplier: “Orshansky used a factor of three because the Agriculture Department’s 1955 Household Food Consumption Survey found that for families of three or more persons, the average dollar value of all food used during a week (both at home and away from home) accounted for about one third of their total money income after taxes.”[1]
And it was not applied uniformly even then — “She followed somewhat different procedures to calculate thresholds for one- and two-person units in order to allow for the relatively larger fixed costs that small family units face.”[1]
But the calculation was not repeated. “The “three-times-the-cost-of-the-food-plan” calculation was done only once, for the 1963 base year poverty thresholds, using the Agriculture Department’s economy food plan.” “Poverty thresholds for years since 1963 have been updated for price changes only using the Consumer Price Index.”[1]
So a current threshold is not produced by recalculating three times a food plan. And the arithmetic does not literally start at 1963 either — the FAQ describes the annual update of the 48-cell matrix as running from the 1978 threshold matrix, with current survey weights entering the final weighted averages. 1963 is the base year of the method; it is not the figure the annual update operates on.[1]
And the FAQ adds its own warning about reading the food logic into the present — “Note that the food share used to develop the thresholds does not represent today’s consumption pattern for either the general population or the poverty population.”[1]
The thrifty food plan was never used
ASPE answers this one flatly — “The thrifty food plan has never been used to update or revise the poverty thresholds.” The plan used in 1963-1964 was the economy food plan, and “The thrifty food plan was not established until 1975, when it replaced the economy food plan at the same general level of cost.”[1]
It is not a budget, so it cannot tell you a rent share
“The poverty thresholds were not developed as an item-by-item budget with specific dollar amounts for each consumption category.” “it is not possible to say what share of the poverty line goes for any specific consumption category”.[1]
Anyone deriving “the poverty line allows $X for housing” is inventing a decomposition the measure does not contain.[1]
There is no single definition of the income you compare it to
Asked whether the guidelines are before-tax or after-tax, gross or net, ASPE answers: “There is no simple answer to these questions.” “Federal, state, and local program offices that use the poverty guidelines for eligibility purposes may define income in different ways.”[1]
“To find out the specific definition of income (before-tax, after-tax, etc.) used by a particular program or activity, one must consult the office or organization that administers that program.”[1]
So “my income is under 138 percent of the poverty guideline” is not a complete statement. Which income, on whose definition, is set by the program — not by the guideline.[1]
The statistical side does have a standard: ASPE notes the Census Bureau uses a standard definition of income for computing poverty statistics based on the official thresholds.[1]
Many big programs do not use the guidelines at all
The guidelines, or multiples such as 125, 150 or 185 percent, “are used as an eligibility criterion by a number of federal, state, and local government programs” as well as programs run by non-profits, hospitals and other entities. The federal list includes Head Start, SNAP, WIC, LIHEAP, CHIP, Pell Grants, Job Corps and Lifeline. Some entries carry their own limit — the school meal programs appear as “National School Lunch Program (for free and reduced-price meals only)”.[1]
ASPE states plainly that “Many means-tested programs do not use the poverty guidelines”, and lists exceptions — “Major means-tested programs that do not use the poverty guidelines in determining eligibility include the following:” Supplemental Security Income (SSI); the Earned Income Tax Credit (EITC); state/local-funded General Assistance in most cases; some parts of Medicaid; Section 8 low-income housing assistance; and low-rent public housing.[1]
And meeting a guideline is not the same as receiving a benefit. “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 guidelines are SNAP, the National School Lunch Program, certain parts of Medicaid, and the subsidized portion of Medicare Part D.[1]
Neither agency publishes a count below the guidelines
“Neither the Census Bureau nor the U.S. Department of Health and Human Services publish tabulations of the number of people below the HHS poverty guidelines” — “although they are used when estimating the number of persons eligible for particular programs”.[1]
“The best approximation for the number of people below the HHS poverty guidelines in a particular area would be the number of persons below the Census Bureau poverty thresholds in that area.”[1]
So an official federal count of Americans in poverty is a thresholds number. If a figure is attributed to “the federal poverty level,” the measure behind it still has to be identified.[1]
The 2026 guidelines were computed without October 2025
“Because of the federal government shutdown in October 2025, the Bureau of Labor Statistics did not publish the Consumer Price Index for All Urban Consumers (CPI-U) for that month.”[1]
So the update was made on eleven months — “the calculation of the 2026 poverty guidelines compares the average CPI-U for the 11 available months of 2025 (excluding October) with the average CPI-U for all 12 months of 2024”.[1]
This fits the standing rule that the guidelines never look forward: “ASPE does not project price changes for the current year; instead, we issue guidelines based on price changes through the most recent completed year.”[1]
The chain from thresholds to guidelines is worth reading carefully, because it is easy to state wrongly. ASPE's worked example: “the 2021 poverty guidelines were issued in January 2021, calculated from the calendar year 2019 thresholds issued in September 2020, updated to reflect the price level of calendar year 2020.” And the conclusion it draws — “Therefore, the 2021 poverty guidelines are approximately equal to the poverty thresholds for 2020 (for most family sizes).”[1]
So the price level is one year behind, not two. The 2021 guidelines start from thresholds of an earlier vintage (calendar year 2019, published September 2020) but are updated to the 2020 price level, which is why ASPE says they approximately equal the 2020 thresholds. Vintage of the starting figures and price level of the result are two different things.[1]
When they take effect is a program question
“The poverty guidelines may be used as soon as they are posted on the ASPE website and the Federal Register each year - usually in late January - unless a program has chosen to make them effective at a later date.”[1]
ASPE also says it does not prepare the official percentage-multiple charts or sliding fee scales that cite it as the source — those come from the offices that prepared them, and the rounding rules and monthly-income procedures in them are set by those offices. It does help, though — “ASPE provides a spreadsheet tool to assist organizations in creating these charts.” and the page carries chart files for 2026 and prior years. With a warning attached: “the numbers in these spreadsheets could differ somewhat from what is used by other federal, state, or other organizations”.[1]
And there is no official “middle class”
Asked whether the government defines other income terms the way it defines poverty, ASPE answers: “The federal government does not have official definitions for such terms as “middle class,” “middle income,” “rich,” and “upper income.””[1]
What this page does not establish
This page rests on one source — the ASPE FAQ, read in full. It gives no dollar figures: not a 2026 guideline amount and not a threshold. Both are updated annually and belong to the tables, not to this explanation. It also names no program's percentage multiple — those are set by the programs, and this FAQ does not list them.[1]
Also not established here: the eligibility rules of any specific program; whether a given program uses before-tax or after-tax income; the Supplemental Poverty Measure, which this FAQ does not address. Retrieved 2026-09-28, HTTP 200.[1]

| 09/28/2026 | Written by claude-opus-5. The source was fetched by script and fixed as text before drafting; the full FAQ (245 lines, 23,932 characters) was read before any sentence was written. 33 quotations were each searched for in the fetched text, and the absence of the phrase “federal poverty level” and of “FPL” was confirmed by counting the expressions themselves, not a phrase containing them. Retrieval note: the page returned HTTP 403 to the fetch from the usual host and HTTP 200 from another, so it was fetched elsewhere and cleaned by the same script (savesrc3.py --file); no text came from a model. The review bundle was built from that same fixed text so the reviewer read the same bytes as the author. | Updated |
| 09/28/2026 | Reviewed by gpt-6-astra (round 1, against the full source). The review corrected a substantive error: the draft said the guidelines lag the thresholds by about two years, conflating the vintage of the starting thresholds with the price level of the result — ASPE's own example says the 2021 guidelines reflect 2020 prices and approximately equal the 2020 thresholds. It also caught that the draft's “a 1963 figure carried forward by price index” omitted the actual mechanics (the 48-cell matrix is updated from the 1978 matrix; final weighted averages use current CPS family weights; guidelines are rounded and equalized), and that the multiplier was not applied uniformly even in 1963-1964 (different procedures for one- and two-person units). Six overbroad statements were narrowed: claims about what “everyone” says, how often the thrifty-food-plan error is asserted, geography in “the federal poverty measure” generally, “nobody publishes”, “always a thresholds number”, and eligibility as a general rule. Added: the school-meal programs' “free and reduced-price meals only” limit, the fixed-appropriation point, ASPE's spreadsheet tool, and the note that the guidelines are used when estimating eligible populations. | Updated |
| 09/28/2026 | Round 2. Three substantive additions: the FAQ's own warning that the food share used to develop the thresholds does not represent today's consumption pattern (important because the title foregrounds food cost); ASPE's warning that its spreadsheet results can differ from what organizations actually use; and the preliminary-versus-final threshold publication schedule, with the preliminary weighted averages updated from the previous year's finals. Three narrowings: the opening no longer asserts how the phrase “federal poverty level” is used, since this page only establishes that the phrase is absent from the source; “OMB has never issued a poverty line” became the supported “never issued the thresholds or the guidelines”; and the claim about 1963 arithmetic was restated so it no longer implies a numerical comparison the source does not make. Review rounds stop here by standing rule. | Updated |
Frequently asked
Is there one “federal poverty level”?
There are two federal poverty measures: the Census Bureau's poverty thresholds, used for statistics, and the HHS poverty guidelines, used for program eligibility.[1]
Which one decides whether I qualify for a program?
For programs that use them, the HHS poverty guidelines, or a percentage multiple such as 125, 150 or 185 percent. ASPE also states that many means-tested programs do not use the guidelines at all, and that most of the listed programs have a fixed annual appropriation — so meeting a guideline is not the same as receiving a benefit.[1]
Are the guidelines two years behind the thresholds?
Not in price level. ASPE's example: the 2021 guidelines were calculated from the calendar year 2019 thresholds issued in September 2020, updated to the 2020 price level, and are therefore approximately equal to the 2020 thresholds for most family sizes. The vintage of the starting thresholds and the price level of the result are different things.[1]
Does OMB set the poverty line?
No. ASPE states that OMB has never issued either the poverty thresholds or the poverty guidelines; its role was a one-time 1969 designation of the thresholds as the official federal statistical definition of poverty.[1]
Is the poverty line three times the cost of food?
ASPE states the three-times-the-cost-of-the-food-plan calculation was done only once, for the 1963 base year, and that thresholds since 1963 have been updated for price changes only using the CPI. Different procedures were used for one- and two-person units even then.[1]
How many Americans are below the HHS guidelines?
Neither the Census Bureau nor HHS publishes such tabulations, though ASPE notes the guidelines are used when estimating the number eligible for particular programs. ASPE says the best approximation is the number below the Census thresholds for that area.[1]
Is the thrifty food plan used to update it?
No. The economy food plan was used in 1963-1964; the thrifty food plan was not established until 1975 and has never been used to update or revise the thresholds.[1]
How much of the poverty line is for rent?
The question has no answer from the measure. ASPE states the thresholds were not developed as an item-by-item budget and it is not possible to say what share goes for any specific consumption category.[1]
Is it before-tax or after-tax income?
ASPE says there is no simple answer: some agencies compare before-tax income, others after-tax, and eligibility can depend on gross, net or another measure. You must ask the program.[1]
Does the poverty line differ by state or city?
The thresholds are the same nationwide. The guidelines are the same for the 48 contiguous states and D.C., with separate sets for Alaska and Hawaii.[1]
Do all means-tested programs use the guidelines?
No. ASPE lists SSI, the EITC, most state/local General Assistance, some parts of Medicaid, Section 8 housing assistance and low-rent public housing as not using them.[1]
Why do the 2026 guidelines involve a shutdown?
BLS did not publish the CPI-U for October 2025 because of the federal government shutdown, so the 2026 calculation compares the average CPI-U for the 11 available months of 2025 with all 12 months of 2024.[1]
Do the guidelines forecast inflation?
No. ASPE does not project price changes for the current year; guidelines are based on price changes through the most recent completed year.[1]
Is there an official definition of “middle class”?
No. ASPE states the federal government does not have official definitions for terms such as middle class, middle income, rich and upper income.[1]
