We’ll bet you didn’t know:

1. Lexington County is one of the fastest growing counties in the state.

2. South Carolina is one of the fastest-growing states in the country.

Most of the population growth comes from people moving from other places.

Moves into South Carolina accounted for about 2.5% of all state-to-state migration in the US last year. Our state accounts for just about 1.6% of the nation’s population, according to data from the US Census Bureau.

In 2016, the estimated total number of people age 1 or older who moved from other states to South Carolina was 165,000. The next year it was slightly higher, about 166,600, and in 2018 that total jumped to about 186,500.

Where are these people moving from?

Some of the top feeder states are the obvious suspects, like North Carolina and Georgia.

Others are likely being fueled by people leaving the country’s largest metro areas.

Here are the top six states that sent new residents in 2018, with estimates for the total number of people who made the move over that year:

• North Carolina: 27,734

• Georgia: 16,110

• Florida: 15,772

• New York: 12,721

• California: 12,103

• Maryland: 7,826

For the states that neighbor South Carolina, the migrations are more of an exchange. The differences between the number of people moving from North Carolina to South Carolina and vice versa are about equal.

For Florida, too, the figures are similar, with just about 500 more Floridians coming to South Carolina.

But for the other states at the top, the exchanges aren’t nearly equal. Just about 4,500 people made the move from South Carolina to New York. Less than 5,000 went to California, and just over 2,000 moved to Maryland.
