Underwater Homes, Exurbs, and Income

Paul Kedrosky’s Infectious Greed picks up on a story in the San Diego Union Tribune which has an interesting graphic of the percentage of underwater homes in San Diego County by zip code:

I agree with Paul that the full map tells the story as an exurb phenomenon (I’ve posted on that in more detail here) and relates to vintage (more on that here).

I also think the inset has something interesting to say about household income and underwater homes. The inset area is not an exurb, but there is big variation in the percentage of underwater homes across a relatively small swath of San Diego. Here’s a blowup of a piece of the inset:

Best to worst performance is light grey, yellow, orange, red, dark grey.

Now, here’s a UUorld map of average household income (2000) for the same swath:

Note how the higher income neighborhoods have fared better. I’ve written more about that here.
