U.S. Synthetic Population Viewer

I have blogged before about a project that is creating a synthetic population for each household and person in the U.S. based on 2005-2009 ACS public use microdata and other data sources. Now one can view this information with an on-line viewer. Whats interesting about the viewer is that you can visually explore combinations of income, household size, and household age across the U.S. More information about the project can be found here, while the actual data can be downloaded from here.
