Two maps, one from 2000 and the other from 2007, show the share of Americans taking on huge new debt to buy a home increasing dramatically across the country. By 2007, the national average was 9% of all borrowers, a rate higher even than at the peak of the U.S. housing boom in 2006.
I think we all have a pretty good sense by now that the housing market went through a bit of a maniacal phase in the recent past. But it's interesting to note that the distribution of mania was far from geographically uniform: it was a phenomenon of the West more than the East (including the interior West to a greater extent than I'd realized); of Minneapolis more than Chicago, and Chicago more than the rest of the Midwest; of Boston and DC more than Philadelphia. And Texas appears to be entirely blameless in the whole fiasco.
And here's a similar map for England:
It's a bit of an apples to oranges comparison, as this map shows housing prices rather than mortgage rates, but it seems that the bubble in England was much more geographically uniform.
