USDA's Census of Agriculture (taken every five years; 2022 edition) at the county level: number of farms and producers, land in farms and cropland acres, land & building value, total market value of products sold, net cash farm income, and the top commodities each county sells. 3,078 counties, $542.5B in total ag sales, 130,806 metric cells. Aggregate (NASS suppresses small cells to protect individual operations) — zero PII. Joins to USDA RMA crop insurance by county FIPS (what a county grows + how it's insured against loss). Canonical /ag-census/{state_fips}-{county_code} page per county. From NASS QuickStats bulk (key-free).
