The United States determines the official poverty rate using poverty thresholds issued each year by the Census Bureau. The thresholds represent the annual amount of cash income minimally required to support families of various sizes.
The methodology for calculating the thresholds was established in the mid-1960s and has not changed in the intervening years. The thresholds are updated annually to account for inflation .
A family is counted as poor if its pretax money income is below its poverty threshold. Money income does not include non-cash benefits such as public housing, Medicaid, employer-provided health insurance, and food stamps .
A sampling of the poverty thresholds for 2018 is included in the table below. A complete list can be found on the Census Bureau’s website.

Poverty guidelines are a simplified version of poverty thresholds and are issued by the Department of Health and Human Services to determine financial eligibility for certain federal programs. For more information on these guidelines, see the Federal Poverty Guidelines.

In the late 1950s, the poverty rate for all Americans was 22.4%, or 39.5 million individuals. These numbers declined steadily throughout the 1960s, reaching a low of 11.1%, or 22.9 million individuals, in 1973. Over the next decade, the poverty rate fluctuated between 11.1% and 12.6%, but it began to rise steadily again in 1980. By 1983, the number of poor individuals had risen to 35.3 million individuals, or 15.2%.
For the next 10 years, the poverty rate remained above 12.8%, increasing to 15.1%, or 39.3 million individuals, by 1993. The rate declined for the remainder of the decade, to 11.3% by 2000. The poverty rate rose each year through 2004, when it reached 12.8%, and then continued to increase, peaking at 15.1% in 2010, the highest poverty rate since 1993. The poverty rate has remained relatively stable between 2010 and 2014. Between 2014 and 2017, it declined 2.5 percentage points to 12.3%. However, from 2017-2018, the rate increased 0.8 percentage points to 13.1%.
Since the late 1960s, the poverty rate for people older than 65 has fallen dramatically. The poverty rate for children has historically been somewhat higher than the overall poverty rate. The poverty rate for people in households headed by single women is significantly higher than the overall poverty rate.
The poverty rate for all people masks considerable variation between racial/ethnic subgroups. Poverty rates for Black and Hispanic people greatly exceed the national average. In 2018, 22.5% of Black people and 18.8% of Hispanic people were poor, compared to 9.5% of non-Hispanic white people and 10.8% of Asian people.
Poverty rates are highest for families headed by single women, particularly if they are Black or Hispanic. In 2018, 24.9% of households headed by single women were poor, while 12.7% of households headed by single men and 4.7% of married-couple households lived in poverty.
There also are differences between native-born and foreign-born residents. In 2018, 13.8% of foreign-born residents lived in poverty, compared to 11.4% of residents born in the United States. Foreign-born, non-citizens had a slightly higher incidence of poverty, at a rate of 17.5%.
Children represent a disproportionate share of the poor in the United States. They are 22.4% of the total population, but 31.06% of the poor population. In 2018, 13 million children, or 18.0%, were poor. The poverty rate for children also varies substantially by race and Hispanic origin, as shown in the table below. .

|White only, non-Hispanic||
 The Census now allows people to report more than one race. In this table, Black includes anyone who reported Black, whether or not they also reported another racial identity. The same is true for Asian, but not white people. Hispanics can be of any race. The numbers for each subgroup do not add up exactly to the total because subtotals for some groups, including Native Americans and Pacific Islanders, are not available in the Census report.
The official poverty measure has been criticized for not accounting for several factors that can affect a family’s economic well-being and for not having been updated, except for inflation, for four decades.
For example, while cash benefits from government assistance programs are included in a family’s income when calculating the official poverty measure, benefits received in-kind such as food stamps, Medicare or Medicaid, employer provided health insurance, housing subsidies, and other social services are excluded. Taxes families pay and tax credits they receive such as the Earned Income Tax Credit do not enter into the official poverty determination.
Additionally, the threshold value a family must earn to escape poverty was developed in the 1960s by combining emergency food budget data from the U.S. Department of Agriculture with an estimate of what fraction of income families spend on food. Although the thresholds are adjusted each year for inflation, some analysts believe these numbers no longer accurately reflect the minimal resources a family requires.
Since 1979, the Census Bureau has published a variety of experimental poverty measures using expanded definitions of income and alternative methods to account for inflation . These alternative measures tend to show lower levels of poverty than the official measure in any year, but the timing of increases and decreases in the poverty rate is very similar across measures. This similarity suggests, despite the criticism it receives, the official poverty measure provides a reliable indicator of changes in the poverty rate from year to year.
In addition to the Census Bureau’s alternatives, a 2010 Interagency Technical Working Group (ITWG) issued a set of recommendations to the Census Bureau on how to develop a new poverty measure to offer a better depiction of the economic well-being of American families and how federal policies affected those living in poverty . Their recommendations heavily drew upon the 1995 National Academy of Sciences report, which outlined a series of poverty measures based on alternative definitions of both income and needs (the amount of resources a family needs to escape poverty).

Following the ITWG report, the Census Bureau introduced the Supplemental Poverty Measure (SPM) in 2011. As illustrated in the table above, relative to the Official Poverty Measure (OPM), the SPM defines income, needs, and family unit in a more broad and comprehensive manner. First, SPM resource measures take into account more than cash. Second, the poverty threshold used in SPM is derived from Consumer Expenditure Survey data, representing the dollar amount spent on a basic set of goods that include food, clothing, shelter, and utilities, which is adjusted for family size and geographic differences. Third, the family unit is broadened to include all related individuals who live in the same address, any co-resident unrelated children, and any cohabiters and their relatives, along with unrelated, non-cohabitating individuals.
A sample of SPM is included in Figure 1 below for years in which they are available. The red line represents the Official Poverty Measure while the blue dotted line represents one of the Supplemental Poverty Measure. The SPM tends to show higher levels of overall poverty than the official measures in any year, although the differences become smaller over time. The incidence of poverty across groups also differs under these measures. Single-mother households fare somewhat better and married couples tend to have somewhat higher rates of poverty than when measured using the official methodology. This discrepancy likely results from the differing level of non-cash benefits received by these two types of families.
In Figure 2, the blue dotted line represents an alternative measure of SPM utilized by Wimer et al. (2013) . This particular method uses the most current threshold and carries it back historically by adjusting it for inflation, instead of recalculating the poverty threshold over time. One advantage of the anchored Supplemental Poverty Measure is it offers an absolute benchmark in which poverty trends can be explained by changes in income and net transfer payments as opposed to over time changes to the threshold. Relative to the traditional SPM poverty measure, the anchored SPM consistently yields higher poverty rates.
