Using Census data, the Pew Research Center's Social & Demographic Trends project has created a typology that groups all 50 states and the District of Columbia by whether they are "magnets" or "sticky" -- or both, or neither. "Magnet" states are those in which a high share of the adults who live there now moved there from some other state. "Sticky" states are those in which a high share of the adults who were born there live there now.
The top states in various categories are listed here:
Minnesota has low magnetism, but is highly sticky; this means we don’t attract many people from other states, but we do a good job of keeping our own folks here.
