In reading the Washington Post credit crisis package I passed along yesterday, I was reminded of a great interactive map that shows the location of nonprime, or the more risky, mortgages.

This mapping tool comes courtesy of the Federal Reserve Bank of New York and breaks down loans by subprime and Alt-A. You can use it a few different ways. By color: Click on one of a dozen buttons on the side to reveal the share of adjustable-rate loans or the number of loans per 1,000 households and the country will be shaded state by state, showing where the most and least are. By number: Click on Washington and all the stats for the state pop up.

There's also a zip code field so you can get even more local with your search.
