Methodology
- Counts represent the number of people aged 1+ who reported a different residence at the survey reference date than they did one year earlier, aggregated across the 5-year sample window 2016-2020.
- Outbound (OUT) flows are reported less frequently than inbound (IN) because the survey captures the destination side of each move. Many county pairs have null OUT counts, which is normal.
- "Total inflow" sums the published MOVEDIN counts across all origin counties, including foreign-region inflows (Africa, Asia, Central America, etc.). It is not the same as net population change.
- Frozen vintage. The Census Bureau has not released a newer county-to-county migration flows file. The 2020 5-yr vintage (covering 2016-2020) is the latest available as of build date.
