The best introduction of the diversity of Los Angeles, California is viewing the population satistics which went in the recent political campaigns of Fall of 2006:
With Glendale and Burbank included the Valley's population is now 1.74 million, larger than every U.S. city except New York, Los Angeles, Chicago and Houston. The U.S. Census Bureau's first-ever breakout of the Valley's population finds that it's within a percentage point or two of Los Angeles, plus or minus, in most major categories. But the Valley is whiter, has less poverty, is slightly more foreign born and a little more likely to drive. Data is from 2005 and derived from an Excel spreadsheet at the website of Rep. Brad Sherman.
Snapshot of selected numbers I found interesting (i.e., categories don't necessarily add to 100%):
