The Pew Research Center takes a look at why people move, and why they stay in the same place:

Home means different things to different people. Among U.S.-born adults who have lived in more than one community, nearly four-in-ten (38%) say the place they consider home isn’t where they’re living now. But there’s a wide range of definitions of “home” among Americans who have lived in at least one place besides their original hometown: 26% say it’s where they were born or raised; 22% say it’s where they live now; 18% say it’s where they have lived the longest; 15% say it’s where their family comes from; and 4% say it’s where they went to high school.

Maybe it’s the nomad in me, but I’ve always thought of home as a place you go searching for.
