Largest percentage gain in NY was... the Bronx! Warms my heart.
NY State would have had a population loss were it not for the City.
That used to be true in IL, but apparently no longer. Cook lost 10K which is about half of the overall loss for the state. The Chicagoland area no longer makes up for losses in downstate IL. In fact the greater Chicagp metro extending into IN and WI lost 7K last year in the new estimates.
I'm surprised a lot of people are leaving Cook County. You see people like on the HGTV show "House Hunters" shopping for a place. I haven't really watched "House Hunters" in like 2 years so I might be a little behind the curve!
