USDA NASS Quick Stats API and bulk files

U.S. estimates span national, state, county, district and ZIP geographies; the provider does not state one database-wide start year. Census aggregates are produced every five years, while current subject bulk files observed on 2026-11-01 were dated 2026-10-31; one API request returns at most 50,000 records.
