It's hard to grasp the full scope of Detroit's foreclosure problem, but The New York Times is here to help. The paper has laid out all 43,634 of the city's foreclosed homes in a single mosaic, representing more than $328 million in unpaid taxes on a single page. The mosaic breaks the amounts down by neighborhood, but the overall effect is still overwhelming, a tidal wave of thumbnails representing an entire city's worth of foreclosed and often abandoned homes. As the city struggles to climb out of debt, these houses are one of the big challenges standing in its way.
