Great Falls, in Virginia (west of DC) is surprisingly obese, given it&#x27;s an EXTREMELY wealthy area (avg home price is &gt;$1 million) and also not racially diverse.  Compare it with the nearby Herndon and Reston areas, both of which are very mixed, both economically and racially.<p>Interestingly, this pattern is the opposite of what you see when comparing NW DC with the rest of the city.  NW DC is more white and wealthy, but slimmer.  The rest of the city is relatively poorer and more diverse, and also more obese.
