[quote=Scarlett][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 would support my hypothesis that we lost or not attract as many young people as in the past due to home affordability, fewer or worse paid entry jobs/junior positions or a combination of those. That (age) is an important factor in determining the median household income.[/quote]
I totally agree with this as well as sdr’s hypothesis. Looking at SANDAG’s projection, the median age of San Diegans will keep on getting older. By 2050, it project SD county median age will be 38.6. So, it seems like SD is attracting older mid career professional and retirees more so than young people.
