Re: Density
Looking solely at a city population or density of the central/core city certainly does a disservice when trying to compare places. The City of Atlanta ranks 37 in total city population while Jacksonville ranks 12 with nearly 80% more population.

However, no would in their right mind would ever put Jacksonville in the same category as Atlanta. Metro population is the best measurement. I don't agree on using CSA. There is an upper limit on the physical distance/expanse that one could consider a metro to be a single metro. Here's a fantastic
youtube video discussing this.
Another way to compare cities, and I would argue this is one of the best metrics for comparing, is to look at the total amount of office space available. JLL has some
fantastic figures on this that they update on a quarterly basis.
Based on this measure, Atlanta is the 8th largest city in the US, maybe 9th depending on how you calculate San Francisco vs San Jose. (I've lumped in New Jersey with New York, from a commercial leasing perspective they're separate, but for us they're the same market.)
If we take a closer look at
Atlanta, we see that between Downtown, Midtown, and Buckhead, there's roughly 56M sqft of office space.
Compare that information with:
Dallas
Houston
Boston
Philadelphia
I wish the JLL reports had a geographic area size in their reports, but they don't. Costar has
submarket maps for many major markets in the US. However, they don't list out the area.
I don't have time to do the calculations myself, but Atlanta's office space is considerably more spread-out than other comparable cities. Which plays into transit heavily. If we want to continue to densify, we need to focus the growth, somehow, on Downtown more than Midtown and Buckhead. But I don't see that happening anytime soon.
