I would guess that by 2050, desalination will be much cheaper than it is today and many cities around the world will be relying on it. Especially the large cities in the Middle East. I don't really see the Sunbelt cities failing anytime soon, but the growth will eventually slow. But the warmer weather and mild winters will always be an advantage they have over Midwest and Northeast cities.
The District, however, stood out among its neighbors. It gained 13,000 residents over the year, driving the population to over 646,000, according to the census figures. That was more new residents than any other jurisdiction in the region. Loudoun County also gained population, almost as much as the District.
More significantly, births were not the only reason the District had population gains. Last year, as in each of the previous three years, the city got more than 6,000 newcomers from outside the District, and almost 3,000 from other countries.
Frey called the District the region’s demographic bright spot.
“While the region as a whole is attracting fewer migrants from the rest of the country and is reliant largely on immigration and fertility for growth,” he said, “the primary source of growth in the District is migration from the suburbs and beyond. D.C. continues to remain demographically healthy despite ups and downs in the rest of the region.”
I remember reading something in the Washington Post about Northern Virginia accounting for over 60% of Virginia's growth which is why I'm still confused as to why with all this growth the DC area still has pretty poor road infrastructure which only worsens the already brutal traffic.
^That makes perfect sense to me. Infrastructure improvements rarely (if ever) can keep up with population growth, especially if that growth is fast. Infrastructure isn't the only thing that lags either, schools, healthcare, public services, etc. usually fall behind also.
I know you said to take these with a grain of salt, and that's fine. But growth rates will obviously not stay the same for another 40 years. Boom cycles tend to last between 20-60 years. We're more than 40 years in for some of these. You will likely see major rate slow-downs with some of the most prolific growers of late.
Not exactly sure how these were calculated but if it were just applying the absolute numbers per year, then it would actually reflect a slowing rate, year over year.
Cities that derive the majority of their water supply from the Ogallala Aquifer (e.g., Austin, San Antonio, Dallas, OKC, et al.) are in big trouble, even more so than the cities that draw their water from the Colorado River (e.g., L.A., S.D., Phoenix, L.V., etc.), as the Ogallala is really in dire shape. I can't see this issue improving in the future either, esp. considering Austin, San Antonio, Dallas, OKC, et al. are currently among the fastest growing cities in the US and desalination seems like a less than optimal solution than for those cities compared to, say, cities in coastal California.

EXACTLY, that is why I did ot this way. The numbers may be off, but not as far off as percentages would be.
