FL is another interesting case. It was expected to gain 1 or 2. But we've entered a time of intense and frequent storms. And the decade's only half over. Will be interesting to see if FL actually surpasses NY, as expected, in the next census. It may not.
Florida will still grew because New York will continue to bleed population down south due to the ridiculous housing, rent and property tax costs.
Well, the worst housing laws (and costs) are in NYC - and NYC (and the downstate in general) are gaining population. It is the upstate that's not keeping up (what are the rent control laws in, say, Troy? Are there any?). Still, NY as a whole does grow, only slowly.
