USDA Census of Agriculture API

What you can build

Aggregate farms, crops, livestock, producers, land use, sales, expenses and assets from the original Census bulk publication. Preserve overlapping domains, units, geography codes, reference periods, confidentiality and CV reliability symbols. These are statistical cells, not farm addresses or ownership/field boundaries. Use this dataset as a sourced input to an application, analytical model or retrieval tool. Retain its native dimensions when joining it with your own records.
