The Child Poverty Rate in the United States Has Exceeded the Rate for Older Adults Since 1974

The poverty rate is one important indicator of economic well-being that varies widely across age groups. In the mid-1960s, 29 percent of U.S. adults ages 65 and older lived in poverty, compared with 18 percent of children under age 18. However, the trends in poverty rates for these two age groups have diverged markedly since 1974, with the rate among older adults decreasing, and the rate among children rising to new peaks in the mid-1980s, mid-1990s, and from 2010 to 2012 following the Great Recession. Entitlement programs such as Social Security and Medicare have been effective in reducing poverty among older adults, but their costs have been rising rapidly as the U.S. population ages. With limited resources, the United States will continue to face difficult trade-offs in improving the well-being of both children and older adults. Investing resources today to reduce poverty among children can increase their future productive capacity and help offset the costs of an aging population.


How Is Poverty Determined?

Each year, the U.S. Census Bureau updates a series of poverty thresholds—specified dollar amounts required to meet the basic needs of family units of different sizes and composition. Families with incomes below 100 percent of the poverty threshold for family units of their size and type are determined to be in poverty. For example, in 2016, the poverty threshold for a family of four with two adults and two related children under 18 years of age was $24,339, compared with a poverty threshold of $14,507 for a two-person family without children headed by an adult age 65 or older. If a family’s total income is less than its poverty threshold, then that family and every individual in it would be considered to be living in poverty. The child poverty rate is the percentage of children under age 18 who live in families with incomes below 100 percent of the poverty threshold for their size and type.

It is important to note that the official poverty definition is based on money income before taxes and does not include noncash benefits such as Medicaid, the Supplemental Nutrition Assistance Program, or tax credits. Poverty status cannot be determined for children in foster care or for people living in institutional group quarters such as nursing homes or prisons.

Why Did the Child Poverty Rate Reach New Peaks in 1983, 1993, and 2010?

Poverty rates for children have fluctuated with economic booms and busts since the mid-1960s. The three peak levels in the graph were reached in the years immediately following economic recessions in the early 1980s and 1990s, and more recently, the Great Recession of 2007 to 2009. While child poverty rates declined in the mid- to late 1980s and again in the mid- to late 1990s, they never dropped back to the low of 14 percent experienced in 1969. Research suggests that changes in income growth, economic inequality, and family structure have all contributed to the persistence of high child poverty rates in the United States. Among children, increasing racial and ethnic diversity, coupled with sizeable gaps in poverty rates between minority children and non-Hispanic whites, also contributed to high levels of child poverty since the early 1980s. In 2016, the poverty rate for black children (31 percent) was three times higher than the rate for non-Hispanic white children (10 percent), and the rate for Latino children was more than two times higher (26 percent).

While the poverty rate among adults ages 65 and older also rose in response to the recession in the early 1990s and the Great Recession in 2007 to 2009, the increases were much smaller—from 8.9 percent in 2009 to 10.2 percent in 2013. Older adults are more insulated from economic downturns because they are more likely to be retired and less likely to experience job loss. Many rely on income from Social Security, which is not impacted by recessions. However, those who also draw some income from retirement accounts may experience drops in income if these accounts lose significant value during a recession.

What Are the Consequences of Experiencing Poverty in Childhood?

Levels of child poverty are important to policymakers and child advocates because poverty not only affects health and well-being in childhood, but also has long-lasting consequences into adulthood. Growing up in poverty—particularly if it is deep or long-lasting—poses significant risks for children’s healthy development. Experiencing poverty in early childhood exposes children to more environmental, educational, health, and safety risks, increasing the likelihood that they will have cognitive, behavioral, and socioemotional difficulties and poorer health. Childhood poverty can also lead to negative outcomes among adolescents, including lower achievement, higher school dropout rates, more behavioral problems, and higher rates of risky health-related behaviors such as teenage childbearing. Finally, research has also documented the long-term impacts of child poverty in adulthood. A study by Greg Duncan and colleagues found that experiencing poverty before the age of 5 reduced the work hours and earnings of young adults in their 30s.

Investing resources today to reduce poverty among children can increase their future productive capacity and help to offset the costs of an aging population.


Data updated on August 15, 2017.



The Data Sheet lists all geopolitical entities with populations of 150,000 or more and all members of the UN, including sovereign states, dependencies, overseas departments, and some territories whose status or boundaries may be undetermined or in dispute. More developed regions, following the UN classification, comprise all of Europe and North America, plus Australia, Japan, and New Zealand. All other regions and countries are classified as less developed. The least developed countries consist of 47 countries with especially low incomes, high economic vulnerability, and poor human development indicators. The criteria and list of countries, as defined by the UN, can be found at http://unohrlls.org/about-ldcs/.

World and Regional Totals: Regional population totals are independently rounded and include small countries or areas not shown. Regional and world rates and percentages are weighted averages of countries for which data are available. Regional averages are shown when data or estimates are available for at least three-quarters of the region’s population.

World Population Data Sheets from different years should not be used as a time series. Fluctuations in values from year to year often reflect revisions based on new data or estimates rather than actual changes in levels.

Country-specific notes include:

  • SAR stands for Special Administrative Region.
  • Kosovo declared independence from Serbia on Feb. 17, 2008. Serbia has not recognized Kosovo’s independence.
  • Macedonia is part of the former Yugoslav Republic.
  • (—) Indicates data unavailable or inapplicable.

    A date range indicates the most recent data point during that time period.


    The rates and figures are primarily compiled from the following sources: national statistical offices’ official websites, online databases, statistical yearbooks, and bulletins from various countries; demographic surveys such as the Demographic and Health Surveys, Multiple Indicator Cluster Surveys, and Performance and Monitoring Accountability (PMA) 2020 Surveys; the UN Demographic Yearbook 2015 and Population and Vital Statistics Report of the UN Statistics Division; World Population Prospects: The 2017 Revision, World Contraceptive Use 2016, and World Urbanization Prospects: The 2014 Revision of the UN Population Division; the International Data Base of the International Programs Center, U.S. Census Bureau; World Development Indicators online database of the World Bank; AIDSinfo online database of the UNAIDS; FAOSTAT online database of the Food and Agricultural Organization of the United Nations; and UIS.Stat online database of the UNESCO Institute for Statistics. The sources also include direct communication with demographers and country experts from around the world. Specific data sources may be obtained by contacting the authors of the 2017 World Population Data Sheet. For countries with complete registration of births and deaths, rates are those most recently reported. For more developed countries, nearly all vital rates refer to 2016 or 2015.
