Making Sense of Census Data With Google Earth

gecensus.stanford.edu — gCensus is a GIS mashup that combines data from the US Census Bureau and places into Google Earth. You can use it to create colorful overlays on maps showing population information (like age, family size, and race) organized by region (counties, cities, or even block-by-block). Best of all, it is completely free to use! Mar 12, 2007 View in Crawl 4
