Bush carried 97 of the nation's 100 fastest-growing counties

New update:

It seems that in 2020 Trump carried 81* of the 100 fastest growing counties and Biden the other 19 (using the Census data for the period 2010-2019).
Indeed, as Forumlurker says, most of them trended Democratic this year, sometimes significantly so. The biggest exception is Osceola County, Florida, the eighth-fastest growing county in that period, which swung massively Republican. Ayy portoricanos de Kissimmee I guess
The four Trump-Biden counties were Teton, ID; Deschutes, OR; Hays, TX; and Williamson, TX.


*asterisk because 1 of them is Matanuska-Susitna Borough, Alaska, for which I can't find actual data, although it's completely unfathomable that Trump lost it given results in previous years and that Trump seems to have carried all the state Legislature districts covering the borough

Just a reminder: fastest growing counties are a poor approximation of counties seeing the most growth because tons of them are small, formerly-rural counties that start to get some exurbs creeping in so they grow 30 or 40 percent in 10 years--from 20,000 to 28,000. Consider Maricopa and Pinal Counties. Which is growing faster? Which is actually seeing more growth?

That's certainly true.
Two of the 100 for example are Gaines and Andrews in the Texas Panhandle, both of which may be described as Odessa exurbs (?) and have fewer than 25,000 inhabitants. Similarly, Williams and Stark in western North Dakota, which are slightly larger but not by much. Coincidentally they are all counties propelled by the oil boom.
