Interesting back and forth over at Tory Gattis's blog on Hou-Orleans, the mega-region running fro Houston to New Orleans and megas in general.
Caught this Richard Florida blog post on the rise of global mega-regions ... Unfortunately, something in their methodology led them to split Texas into two mega-regions, the Dallas-San Antonio corridor, and the Houston-New Orleans corridor, extending all the way the Florida panhandle (see map on p.27). Of course, anybody familiar with Houston's economy knows it has far more connections to the rest of the Texas Triangle cities than it does to NOLA and points east, and I let him know in the comments. The true mega-region is the Texas Triangle Megalopolis, as identified by the Federal Reserve Bank.
But some disagree:
I wouldn't be so quick to dismiss the Houston-New Orleans corridor. That's the petrochemical belt, and though Houston is admittedly the dominant pole in that belt, we do have a very strong connection to the points in between, such as Beaumont and Lake Charles and Lafayette and the famed cancer alley between Baton Rouge and NOLA. There are a lot of strong connections tieing Houston in that direction. I don't see a similar connection between Houston and San Antonio, nor the points in between.
Another points out:
Probably a much better and more thorough examination of this phenomenon in the US is happening at america2050.org ... It's very interesting stuff, and really just getting started, having had an official organization for just three years. But it's got some top demographers and planners working on it.
Hmmmmm ... These are empirical issues. We use a comprehensive methodology to identify mega-regions, using light-emissions to pinpoint contiguous geographic areas. It's Hou-Orleans that's a distinct mega that way: There are significant light gaps in the Texas Triangle. I'm a big fan of what America 2050 is doing, but our method for identifying megas is different and we believe to be a significant advance in two respects. One, it takes guess work out of the process, allowing mega boundaries to be determined purely on observed light data. Two, it enables us for the first time to systematically identity and compare megas not just in the US but worldwide.
