Beginning in 2011, the Census Bureau began publishing the Supplemental Poverty Measure (SPM), which extends the official poverty measure by taking account of many of the government programs designed to assist low-income families and individuals that are not included in the official poverty measure.
The Census Bureau provides poverty data from several household surveys and programs. Here you can find poverty estimates, learn about these surveys and programs, and get guidance on how to choose the right estimate for your needs.
There are two slightly different versions of the federal poverty measure. Poverty thresholds are updated each year by the Census Bureau. Poverty guidelines are the other version of the federal poverty measure and are issued each year in the Federal Register by the Department of Health and Human Services. See this site for more explanation.
The Poverty and Equity Data Portal is the World Bank Group’s comprehensive source for the latest data on poverty, inequality, and shared prosperity. The portal allows you to explore several poverty and inequality indicators for countries and regions as well as explore countries by various income levels – low income, lower middle income, and upper middle income, and access poverty and inequality data for fragile, IDA and other country groupings.
