Loading county data
This visualization system maps food flows between counties in the United States. Total food flows are provided in units of mass [kg] for the year 2012.
Food flows are unique to each county, so the list of partner counties and the color scale changes with each county selection.
There are three categories of relationships that can exist between counties:
Note that the list of partner counties and the color scale changes with each county selection.

This information is generated by the Food Flow Model, a data-driven methodology to estimate spatially explicit food flows. The Food Flow Model integrates machine learning, network properties, production and consumption statistics, mass balance constraints, and linear programming. A full description of the methods used to generate county-to-county food flows in the United States is provided in the accompanying academic journal article (Lin et al, 2019).
The following is a list of Standard Classification of Transported Goods (SCTG) food categories included in this study.
