This map shows American Indian and Alaska Native (AIAN) population statistics across five geographic levels in the 50 states and DC. Click any feature to open a popup with population, race/ethnicity, income, and rurality figures. Use the search bar to jump to a specific native area, place, metro region, or county.
A person is counted as AIAN if they identify as AIAN alone, or as AIAN combined with exactly one other race. AIAN people who identify with two or more additional races are placed in the "Other" group, as are all non-AIAN people who report two or more races.
Counties, native areas, local areas, and metro regions can be viewed at five buffer sizes: 0, 5, 10, 15, and 20 miles. At 0 miles the geography uses its Census-published boundary. At wider buffers, the geography is expanded outward by that distance, and the population, income, and rurality statistics are recomputed across every block (or block group, for income) whose centroid falls inside the buffered footprint, plus every block already attributed to the geography by the Census Bureau. People near several geographies are counted toward each one independently, so summing across geographies will double-count overlap zones.
AIAN share of local population — AIAN count divided by the geography's total population.
AIAN share of national population — AIAN count divided by the national AIAN total (excluding Puerto Rico and US territories). Uses a log scale because national share spans several orders of magnitude across geographies; shares are logged to emphasize relative differences between geographies.
Racial makeup — hue is the racial/ethnic group with the largest share in the geography. Color intensity scales with the size of that plurality: a place that is 100% one group reads at full saturation, while a place where the plurality is small reads as a pale tint of the same hue.
Median household income — at the 0-mile boundary this is the median household income reported directly by the Census Bureau for that geography. At wider buffers no published median exists, so the income brackets reported for each block group within the buffer are added together and a median is interpolated from the combined distribution. Coloring uses the 5th-to-95th percentile range of incomes pooled across every geography in the dataset.
Urban–rural type (RUCA) — for tracts, the published rural-urban commuting class from the USDA. For larger geographies a single RUCA value is misleading, so we instead show the population-weighted majority class — the rurality category that the largest share of the geography's residents actually live in. The popup also shows the full RUCA distribution.
While most data is aggregated by the Census Bureau through the block level, some data are available only at coarser levels: in this tool, RUCA values are reported only at the tract level, and the smallest unit at which income is reported is the block group. To apply these data to either tract-crossing boundaries or buffered areas where no pre-aggregated Census data is available, we use a population-weighting approach to estimate RUCA and income statistics. For RUCA, each block in the geography is assigned its parent tract's class, and the class with the largest population share becomes the geography's modal value. For income, each block group is placed at the population-weighted average of its blocks' centroids; the income brackets of every block group whose centroid falls inside the geography are summed, and the median is interpolated from the combined distribution.
2020 Decennial Census (race counts); 2016–2020 American Community Survey 5-year estimates (income); USDA ERS rural-urban commuting codes (2020); TIGER/Line 2020. Median household income comes from ACS sample estimates, which can be unreliable or suppressed at small geographies; suppressed values appear as "—" in the popup.
