California Lost Over 99,000 a Year From 2000 to 2004
Outmigration from California, our largest state, averaged over 99,000 annually between 2000 and 2004, according to a recent Census Bureau report on Domestic Net Migration in the United States: 2000 to 2004. Total outmigration during this period was 396,156. This marked a slowdown in outmigration: in the decade between 1990 and 2000, California lost 2.2 million people, with an annual average of 221,000. The report notes that the drop in California's net outmigration after 2000 had an effect on surrounding states. During the 1990s, the flow of people from California led to substantial migration gains for many western states. As California's net outmigration has lessened in recent years, so too has the net immigration to many of theses states.
These data in the report [PDF; File Size: 5.11 MB] are based on the Census Bureau's annual July 1 population estimates for states, counties, and metropolitan and micropolitan areas. The report also has net migration data for the most populous metro and micropolitan areas and ranks the top counties in net outmigration and immigration. Note: Since this report was released, we have released the July 1, 2005 state and county population estimates.
