A free directory of the agencies and portals that publish population and demographic data — the U.S. Census Bureau, the American Community Survey, data.census.gov, BLS, CDC/NCHS, BEA, IPUMS, the UN Population Division, Eurostat, and the World Bank. Each entry lists the body's role, jurisdiction, and official URL. Platform-curated public-domain reference data, free for researchers, planners, and data engineers.

A free, platform-curated benchmark set of United States demographics — the 2020 Census count, current population estimates, median household income, the official poverty rate, median age, homeownership, household size, foreign-born share, and educational attainment — drawn from the U.S. Census Bureau and CDC/NCHS. Every figure is period-tagged and sourced. Built for market researchers, planners, and data teams.

A free glossary of census and demographic terms — the decennial census, apportionment, redistricting, census tracts and block groups, metropolitan statistical areas, FIPS codes, poverty thresholds, and the OMB race-and-ethnicity standards — with precise definitions from the Census Bureau and OMB. Platform-curated public-domain reference data, free for analysts interpreting or joining census datasets.

Official reference for the Demographics & Census vertical. Census products are free, so the marketplace value is in what the bureau doesn't publish: current-year small-area estimates, cross-tabulations suppressed in public tables, and geography crosswalks that actually work. Buyers are site-selection agents, lenders, and market-sizing analysts who need block-group-level answers now, not as of the last survey wave. Sellable datasets include current-year population and income estimates with your modeling methodology stated, custom cross-tabs (age × income × tenure) built from microdata with disclosure rules respected, and boundary crosswalks between vintages with allocation weights — see the example rows. Always publish your error bounds; a modeled estimate with stated uncertainty outsells false precision. Aggregate data only — no individually identifying records. Listing is free, sellers keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30 (full schedule: GET /api/meta), and the platform never stores your data (zero-storage relay from your endpoint per sale).
