Official US 2010 Census Results

I think Bend also experienced growth the same way Las Vegas and Phoenix did--it was a low-cost housing market of a certain size convenient to some wealthy, high-cost housing markets.

You can see the development of Maricopa, AZ (the town) in Google Satellite views by backing out or in of zoom, one step at a time. At some point the image changes and you either gain or lose most of the housing.

Okay, so the rises in Black population in Minnesota and North Dakota are a little strange. ND's actually doubled - its 2000 Black population was very largely affiliated with the air force bases.
Minnesota's is up from 3.4 to 5.1%, or by a hundred thousand people. That is, it's grown as fast  as the Asian population percentagewise, and as fast as the Hispanic population in raw numbers.

A significant share of that number may be Somali, although the Internet gives conflicting estimates.

If you divide Florida along the southern border of districts 5, 8, and 24, that neatly divides the excess population for two districts between either half of the state.

It looks like one new district in central Florida, not far from (but not near) Orlando, and perhaps a Gulf Coast district that sends 16 and 25 back to the Atlantic Ocean or moves 13 up a little bit to the north.

Or maybe a new D district is created in Orlando and Webster still has a district nearby he can represent when they clean up the mess of the old gerrymander to put FL-24 in there.

My jaw dropped. WOW. 25%?!

There's a state college and federal penitentiary in Gilmer County.  My guess it is Gilmer's growth something to do with one or both of those institutions.

The prison appears to have opened since 2000.

It's a poor, rural county--as soon as I saw JL's question I was googling "gilmer county prison".

The fertility rate is the number of children an average woman bears over the course of her life. The replacement rate is 2.1. If the average woman has more children than that, population grows. Fewer, and it contracts. Today, America's total fertility rate is 1.93, according to the latest figures from the Centers for Disease Control and Prevention; it hasn't been above the replacement rate in a sustained way since the early 1970s.

The 2020 census might show an even smaller growth figure than the historically low 2010 census.

You've forgotten to take immigration or increased life spans into account. Americans can have zero children but still see increased population.

True... but we do also know that immigration was high in the first two-thirds of the last decade, and has been much slower since about 2008, with no sign of it increasing. That would reinforce the declining birth rate trend.
