For the most part, looking at America’s largest metro areas (the 52 metropolitan statistical areas with populations over a million) the fastest growth in millennial populations tend to be in the Sun Belt and Intermountain West. Leading the way is, San Antonio, Texas, where the 20 to 29 population grew 9.2% from 2010-13, an increase of 28,600.
Right behind it, also in the Sun Belt, are Riverside-San Bernardino, Calif. (8.3%); Orlando, Fla. (8.1%); and Miami (7.7%).
Surprisingly Detroit, long considered a demographic basket case, comes in it at No. 5 in our study, with an impressive 6.8% increase. Given the implosion in the population in the city of Detroit, this growth is likely to have taken place almost entirely in the region’s suburbs, which have done far better both economically and demographically than the core.
