I love seeing statistics visually. Tufte is awesome. So chil.us got me all kinds of excited. The interesting navigation structure at the bottomo of the page allows you to browse through different visual displays of statistics, information, and history about Chicago. From the site:

chil.us examines Chicago’s status as a global city. The current condition of the Chicago Megalopolis is revealed with maps, diagrams and statistics. The project charts comparative states of Chicago’s land use, growth, population densities, energy/natural resources, infrastructural networks, economic/leisure activities, and photo-slices taken along prime travel-routes.

The research project is an effort to document a broad informational context for those currently working on and/or thinking about the design and planning of Chicago.

My favorite parts are the pink navigation sections that look at family, household, and living statistics.
