South Carolina had the 10th largest net in-migrations in the U.S. between 1990 and 2010, according to the Manhattan Institute report. The other nine states on the list experienced more in-migration in the 1990s than in the 2000s, but according to U.S. Census Bureau data, South Carolina saw more people arriving during the 2000s, making the state the sole exception.
According to data from the Internal Revenue Service provided by the authors, 111,377 people migrated into South Carolina in the 2009-2010 period. The states that sent the most people there were North Carolina, Georgia and Florida.
In this period, the unemployment rate in South Carolina went down, while it went up in all three of the other states, no doubt making it an attractive destination for those out of work.
