I was reading the NY Times on my way to work today and found out there are a serious of articles about ACS2005-2009.  The most amazing thing is that they developed this interactive map at the Census Tract level for the whole nation.  The maps show household income, home value, education and race and ethnicity at each tract and also the percentage change from the Census 2000.

Here is the link.  You got to check this out!
