Data for: Shocks to agri-food flows between counties in the United States from 2018 to 2022

This dataset provides estimates of annual agricultural and food commodity flows (in kg) between all county pairs within the United States from 2018 to 2022. The database provides 343.7 million data points, since pairwise information is provided between 3134 counties, for 7 commodity categories, and 5 time periods. The commodity categories correspond to the Standardized Classification of Transported Goods and are:
- SCTG 1: Iive animals and fish
