Want to know male/female ratio of a city before you move there? Want to know the income levels, racial composition or educational levels of any part of the US? Well, you can find out all that and more on Social Explorer, a site that maps the demographic data of the US in fascinating detail.

All based on census data, you can spend hours looking at detailed information for your neighborhood – I just found out that 45-50% of the people on my block have never been married! And you can go back in time and look at how things looked in 1940 too.

Go forth and get to know your neighbors through data!
