Reposted, for the benefit of Dallas Morning News readers: Here's an interesting followup to my Atlantic column (free link good for three days), discussed below: a chart comparing the number of building permits per 1,000 population in different metropolitan areas. It demonstrates the same phenomenon I discussed. The cities toward the bottom of the list, those with the fewest permits issued, fall into two categories: those with low demand and low prices (Detroit, Buffalo, Rochester, etc.) and those with high demand and high prices (LA, San Francisco, Boston, etc.). The fast-growing Sunbelt cities where housing is cheap are at the top of the list. Compared to the economic research I cited, this is a fairly crude way of cutting the data. But it did help reassure my Pasadena-based fact-checker that, despite the new construction she sees around her, it really is hard to get a permit in our area.
