The U.S. Census Bureau surveys U.S. residents on their place of birth to compare with the place they currently live. This provides an idea of geographic mobility and migration. The native population includes everyone who was born in the U.S. or was born outside of the U.S. but had at least one parent who was a U.S. Citizen—all other residents are classified as foreign born. The native population born in the U.S. is further broken down to identify residents that were born in the same state they currently live and those that were born in another state in the U.S.
When looking at the whole state of Georgia by county, we can see that the counties in metro Atlanta and those along the coast or state borders have higher percentages of residents born in another state (37% in metro Atlanta). For Georgia as a whole, 34% of residents were born in another state, but when you exclude the metro counties, this share drops to 23%. Since Atlanta is a major employment destination, it makes sense that there are a higher number of “transplants” that have moved to Georgia from another state. Rural counties in central/south Georgia have some of the lowest shares of residents born in another state.
