This is an interesting interactive graphic on home sales in the DC area. A metro area, because of the strong economy, had one of the smallest bubbles. The NW and central city ( I mean DC part of the DC metro area) was least effected. Probably due to many young professionals (mostly white) moving into the city because of bad traffic in the suburbs and a better night life. The already wealthy areas in the NW suburbs the increases were real from 2000 to 2005 and was not just part of the Bubble. The African American population has plummeted the last decade from near 70 percent of DC to close to 50 percent.
