St. Louis is sometimes in the top rankings - but not always on a possitive note - so I have been doing some research....
According to City-Data .. St. Charles County, MO is ranked #100 in "Top 101 counties with the largest number of people moving in compared to moving out ".
Moscow Mills, MO is ranked #100 in "Top 101 cities with the largest percentage of mobile homes " - no comment on whether this is good or bad :)
Jefferson County, MO is ranked #69 in "Top 101 counties with the lowest percentage of residents relocating to foreign countries in 2006".
Hear's a good one - Town And County, MO is ranked #11 in "Top 101 cities with the largest percentage of elementary and middle school students in private schools ", while Des Peres is ranked #19, Crestwood #26, Creve Coeur #37, Oakville #44, Affton #64, Webster Groves #73, Mehlville #77, and Washington #87.... wow - this could be looked at as good - people can afford private schools... or maybe the public schools are just that bad!! High School stats are up there too - with Town and Country being #5, etc....
Jennings was the one city in the St. Louis area under "Top 101 cities with the largest percentage of divorced people age 25+ " and ranked near the bottom at #95.
Here's a funny one - Clayton is #34 in "Top 101 zip codes with the most offices of lawyers in 2005", while Creve Coeur is #19 for most Doctor offices, Chesterfield is #31 for most beauty salons, and Clayton #76 for most museums.
$$$ Ladue ranks #45 in income, while Farmington is ranked #82 for the number of people in mental institutions.

I started out just browsing to see where St. Louis ranked in housing, and ended up with something else - in some ways more interesting.
