Interesting Map of population growth

There is a lot of truth to this. Who would really want to live in the hot south without AC?

 

The whole Tennessee Valley Authority is what made living in the south barely livable.

The map is a bit deceptive since it uses census population figures and many of the areas which were on it were occupied by people not counted due to it during part of the time.  Any area which was not part of census should have been grayed out so it would indicate no polling.

The map also seriously under represents urban populations because it maxes out at a population density of 90 people per square mile.  Counties containing large cities or close to large cities frequently have population densities of 10 times or more of that population density.  My county, Chautauqua is predominantly rural but in 2010 it had a population density of about 100/square mile.  Nearby Erie County which contains Buffalo and most of its suburbs had a population of more than 900/square mile but both have the same value color (90 or more/density) on the map.

 

If you watch the map carefully in its later decades (from1920-2010) in the area of the Great Plains, you can see the populations of some counties fall as the population on the high plains fell because of the major changes in agriculture resulted in much larger farms/ranches worked by many fewer people using much more machinery.
