area_demographics
shallowcom.thestackunderflow/datum-property · Verify this server
Population and median household income for the county containing a point, from American Community Survey 5-year estimates. Composes two ingested datasets (§22.2): TIGER/Line resolves the coordinate to a county GEOID, then the ACS layer is read by that key. Pass `geoid` directly to skip the boundary lookup. Values are survey ESTIMATES with margins of error, not counts, and a suppressed estimate is returned as null rather than filled in. The release that produced them is in `dataset_version` and in each metric's `period`. When to use: Use for "how many people live in this area" or "what is the median income there". Give a coordinate, or a county GEOID from admin_areas. Billed as property.area_demographics at 1c. Every response includes a sources[] array naming the data origin and licence.
