You can always go through the Census Bureau - "http://factfinder.census.gov/home/saff/main.html?_lang=en"
The place most people will recommend is the "Site to do Business" - "http://www.stdb.com/"
It comes included if you're with the CCIM Institute, but I believe for basic access it's $250. The information is very easy to read and decipher.
