The website city-data.com has race and crime data for almost every city in the US. Here's an exercise you should all try - Pick a city at random. Then look at the race stats and make a guess at the murder rate for that city.

You can reverse it as well. Scroll down to the murder rate, then guess the % black population.

You can do the same for each state with the following two sites - http://quickfacts.census.gov/qfd/states/00000.html (race stats); and http://www.disastercenter.com/crime/uscrime.htm (crime stats)
