(B)ad net migration numbers can be the result of an unusually high number of people leaving, or an unusually low number of people moving in. And in the case of Illinois, it appears to mostly be the second.
In per capita terms, Illinois’ gross out-migration rate ranks just 29th out of the 50 states and the District of Columbia. In other words, Illinois residents are actually less likely to move out than are residents of the median state.
But things don’t look so good when it comes to gross in-migration. Adjusted for population, Illinois attracts fewer newcomers than all but two other states: New York and Michigan.
That means Illinois’ migration problems are mostly about how few people come here, not how many people leave.
There’s lots more to this, so make sure to read the whole thing.
