What this dataset measures
The Census Bureau's annual population estimates are the official between-census measure of state population change, and they split migration into domestic (between states) and international. Five full estimate years since the 2020 Census show the post-pandemic pattern. Rates per 1,000 residents let small and large states be compared.

Net domestic migration per 1,000 residents, July 2020 to July 2025
Question: Which states gained and lost the most people to moves between states since 2020?
Result: From July 2020 to July 2025, South Carolina (+71.0 per 1,000 residents) and Idaho (+70.8) gained the most from moves between states; New York (-52.0) and California (-41.2) lost the most. In raw numbers California lost a net 1.63 million people to other states and New York 1.05 million; Florida gained 829,000 and Texas 760,000.
Operation: Sum five annual domestic-migration components per state and divide by the July 2020 population
Scope: 50 states and the District of Columbia

The Census Bureau's Population Estimates Program estimates each state's population every year between censuses. Domestic migration is estimated mainly from changes in addresses on federal tax returns, Medicare enrollment and Social Security records.

Limitations and reproducibility
Reproducible: Sum DOMESTICMIG2021 through DOMESTICMIG2025 for each state row (SUMLEV 040) in NST-EST2025-ALLDATA.csv, and divide by POPESTIMATE2020 times 1,000. The state values sum to exactly zero, as net domestic migration must.
- Net domestic migration is moves in from other states minus moves out to other states; it says nothing about where movers came from or went, or why.
- International migration is excluded, so a state can lose residents to other states and still grow (California and New York both gained international migrants).
- These are estimates built from IRS tax-return addresses, Medicare enrollment and other administrative records, not a count, and each new vintage revises earlier years.
- The rate's denominator is the July 1, 2020 population estimate.
- Puerto Rico is excluded.
