Median Household Income (ACS)

Limitaciones

Race/ethnicity of householder is served on the topic-specific race_iteration column, NOT the shared demographic axis, because the Census race-iteration tables OVERLAP: 'white' is White alone NOT Hispanic (B19013H) and 'hispanic' is Hispanic of any race (B19013I), but the remaining groups are race-ALONE iterations (B19013B-G) that INCLUDE Hispanic householders - a Hispanic Black householder is in both 'hispanic' and 'black'. The demographics dimension promises mutually exclusive categories, which these rows cannot honor (the Census publishes no other non-Hispanic income splits), so never combine rows across race_iteration values; 'all' (B19013) is all households and is the default pin. population_by_race (B03002) IS mutually exclusive and stays on demographic. Universe: households; race is the HOUSEHOLDER's. Dollars are inflation-adjusted to each vintage's END year, so cross-vintage comparisons mix different dollars. Medians never sum or average across geographies or categories. Published medians are censored at BOTH scale ends and preserved as-is (see the jam_values listing on the column): 250001 means '$250,000 or more' and 2499 means '$2,499 or less'. A NULL median means the source could not compute one - rare for the 'all' row (about 1 percent of tracts, never at county/state grain) but increasingly common for small race iterations at tract grain (from about 10 percent of tract rows for 'white' to nearly all for 'native_american' and 'pacific_islander'), because a median needs enough sampled households in the group to estimate. ACS 5-year period estimates: the year column is the vintage END year and each estimate pools five years of survey responses (2024 = 2020-2024). Consecutive vintages share about 80% of their sample, so the series is heavily smoothed - never difference overlapping vintages as if they were annual change. Estimates are survey-based and carry 90% margins of error (the *_moe columns); tract-level margins can be large relative to the estimate. All levels serve vintages 2020-2024 only, on 2020-vintage tract boundaries. State rows have NULL county_fips, district_code, and tract_geoid; county rows carry only county_fips, district rows only district_code, tract rows only tract_geoid. District rows cover the ~180 standard (city/county) districts only: the Census publishes school-district estimates at unified school district geography, which has no codes for charter schools, RESAs, or state agencies, and its few Census-only districts (e.g. the Fort Stewart military district) have no GCD district code and are dropped.
