This map shows census information from the 2000 U.S. Census. Each polygon is one census tract; census tracts are designed to have about 3000 people each.
The darker the red, the higher the value in that tract. Full red means that it's at the maximum; full white means it's at the minimum.
I don't draw borders on the tracts that only take up a few pixels. That's why urban regions tend to have a ring around them with no borders. NOTE: when you are looking at census data, the farthest you can zoom out is to see roughly 2/3 of the US at once. (At some point, I'll make the tiles for farther-zoomed out, but not right away.) In the other direction, Google added a few more zoom levels in API v.2 that my tile server doesn't know about. It usually isn't interesting to zoom in that far, so fixing that isn't a priority for me. You will have a better experience if you clear your browser's cache before doing much.How can I save a map view to look at later?
