Census Bureau stats are searchable by state and county. This site seems to have an appreciation for its overwhelming amount of data, and does its best to simplify the search process. But the database makes it worth the visit. This interactive map site is great for the child who left her atlas at school or who just wants to find her favorite cousin's hometown. Map Quest can provide directions from point A to point B, pinpoint a street address, or show you a whole country.
Kids can trace their route and look up attractions along the way.
An ideal cyber address for our stat-obsessed culture. As a rule, the newly created NIMA funnels most of its maps and images to the military. But the site also provides information to civil users.
