This article examines the economic security of the American Indian and Alaska Native (AIAN) population by exploring AIAN receipt of Social Security benefits and Supplemental Security Income (SSI). This analysis uses data from the 2005–2009 American Community Survey Public Use Microdata Sample, which provides a larger AIAN sample size than many other sources, thereby enabling more reliable estimates. We find that adult AIANs are less likely to receive Social Security benefits and more likely to receive SSI than are adults in the total population. In both programs, median benefit amounts are lower for AIAN recipients than for recipients in the total population.
