I’m gathering up demographic data for areas for my pre-pre-pre-alpha church plant.
The District of Columbia has changed so much in the last few years, but I’m still going to start with Census 2000 data because it gives me a base line for demographic changes. (I’ll report on more current info as I find it.)
A good place to visualize this data is a ZIPskinny — if for no other reason than it helps one get comfortable with reading this kind of data.
