What Is the Poverty Line in America and Who Is Actually Poor?

May 17, 2026 · 3 min read

The federal poverty line is one of the most consequential numbers in American policy — determining eligibility for dozens of programs serving tens of millions of people — and it was designed in 1963 using a methodology that most poverty experts now consider inadequate.

The Origin Story

In 1963, Social Security Administration economist Mollie Orshansky was trying to create a threshold to measure economic hardship. She used USDA data showing that low-income families spent about one-third of their income on food, and the USDA's estimate of the minimum cost of an adequate diet for different family sizes.

Her method: minimum food budget × 3 = poverty threshold.

That formula, adjusted each year for inflation using the Consumer Price Index, has been the basis for the federal poverty measure ever since.

The problem: in 1963, food costs represented a reasonable proxy for overall economic hardship. Today, poor families spend far more than one-third of their income on housing, healthcare, transportation, and childcare. The 1963 assumption no longer reflects how poor families actually spend money.

What the Official Measure Misses

Housing is the biggest gap. In major metro areas, even modest rental housing consumes 40-60% of a poor family's income. The poverty measure was designed for an era of significantly lower housing costs relative to income.

Healthcare costs have also changed dramatically. Employer coverage, Medicaid, and ACA subsidies affect whether healthcare is a budget item at all for poor families — but the official measure doesn't account for this variation.

The official measure also doesn't account for taxes paid (FICA, income tax) or government benefits received (SNAP, EITC, housing assistance) — meaning the full picture of economic resources is invisible.

The Supplemental Poverty Measure

In 2011, the Census Bureau introduced the Supplemental Poverty Measure (SPM) as a research alternative that addresses many of these gaps.

The SPM:

Sets thresholds based on actual spending patterns for necessities (food, clothing, shelter, utilities) rather than Orshansky's formula
Adjusts for geographic cost-of-living differences
Accounts for taxes paid and government benefits received (SNAP, housing subsidies, tax credits)
Has different (usually slightly lower) rates than the official measure

The SPM reveals something important: government benefits dramatically reduce poverty. When SNAP, the EITC, Social Security, and housing assistance are counted, far fewer people fall below the poverty threshold than the official measure suggests.

This cuts directly to the political debate about safety net programs: when someone argues that these programs "don't reduce poverty," they are often comparing to the official poverty measure that doesn't count them. The SPM shows they do reduce poverty — substantially.

The Child Poverty Lesson

The clearest recent evidence that poverty is a policy choice came from the American Rescue Plan (2021):

Congress expanded the Child Tax Credit to $3,000-3,600 per child, made it fully refundable (available to families with no income tax liability), and provided it as monthly payments rather than an annual tax refund.

Child poverty, measured by the SPM, fell from about 15.3% to 5.2% in 2021 — an unprecedented decline in a single year.

When the expanded credit expired at the end of 2021 because Congress didn't extend it, child poverty rose sharply back in 2022.

The experiment proved that child poverty at the scale America experiences it is not inevitable. It is the predictable outcome of policy choices — specifically, the choice not to provide families with children the income support that would keep them above poverty. Countries like Denmark and Finland have child poverty rates below 3% precisely because they make different policy choices.

Whether America chooses to make those choices is a political question. The economics of how to do it have been demonstrated.

FAQ

What is the poverty line in America in 2026?

The federal poverty level (FPL) for 2026 for a family of four is approximately $31,200. For a single individual, it is approximately $15,060. These thresholds are updated annually for inflation using the Consumer Price Index. Programs like Medicaid, SNAP, CHIP, and subsidized ACA health insurance use the federal poverty level as an eligibility benchmark, often at percentages like 100%, 130%, or 200% of the FPL.

How is the poverty line calculated?

The official poverty measure was designed by Social Security Administration economist Mollie Orshansky in 1963. She estimated the minimum cost of an adequate diet for families of different sizes, then multiplied by three (because surveys showed poor families spent about one-third of income on food). That formula, adjusted only for inflation, has remained the official methodology ever since. Critics note that housing, healthcare, and childcare now consume far more than one-third of poor families' budgets, making the 1963 formula increasingly out of date.

How many Americans live in poverty?

According to the official poverty measure, about 37 million Americans (approximately 11% of the population) live in poverty. The child poverty rate is higher. Using the Supplemental Poverty Measure — which factors in government benefits, taxes, regional cost-of-living, and non-cash assistance — the numbers shift: government programs like SNAP and the Earned Income Tax Credit significantly reduce poverty rates as measured by the SPM. The American Rescue Plan's expanded Child Tax Credit temporarily cut child poverty nearly in half in 2021 before expiring.

Why did child poverty spike after the American Rescue Plan expired?

The American Rescue Plan (2021) expanded the Child Tax Credit to $3,000-3,600 per child and made it fully refundable (available even to families with no tax liability) and provided monthly payments. Child poverty, measured by the SPM, fell from about 15% to about 5.2% in 2021 — a historic low. When the expanded credit expired at the end of 2021, child poverty rose sharply back toward prior levels in 2022. This demonstrated that child poverty is a policy choice, not an immutable condition.
