With the goal of informing local food action planning, this paper develops a first county-level database detailing agrifood consumption and production across 3,114 counties in the United States. The database covers 12,070 food items that comprise the entire diet, mapping them to the production demand of 95 agrifood commodities. Agrifood demand is delineated further into fresh and processed components, along with characterization of animal feed, and compared with local food production to yield the current local agrifood capacity (CLC). CLC Results are shown for individual agrifoods and for aggregated categories (e.g., 0.03 for fruits & nuts, 0.24 for vegetables, 0.31 for non-meat animal products) across all U.S. counties. CLC results for the entire diet find that a large proportion of US counties can be self-sufficient in individual agrifood commodities (ranging from <0.5% of counties for agrifoods like hops, papayas, and artichokes to 59% of counties for beef), and 23% of US counties can supply over half of their total human dietary demand through local production, but only 9% of the US population resides in these counties. Such granular, subnational baseline are essential to inform future goal setting for urban agriculture.
