[quote=sdrealtor][quote=AN]Another interesting data I found is median age. in 1990, the median age in SD county was 31. In 2000, it went up to 33.2. In 2010, it’s 35.3.[/quote]

That is a very big change for a place to go through. Probably due to the shift away from a military dominated town to one that now has a major presence in private industries combined with people aging in place.[/quote]

That and falling birth rates. On the other hand, dynamics of the median age may yet reverse itself (briefly) because the median age for Hispanic people is still only 27.6 and they account for about two thirds of total population growth.

Looking too closely at profilewarehouse isn’t recommended, what they have is only estimates, and estimates come with assorted errors. One interesting error is in their estimates for 91902. I actually emailed them about it a year or two ago, but it’s still not fixed. Who’ll be the first to spot it?
