By far the average family in 4S is younger upper middle class. There are lots of kids in the community. I live on a double ended Cul De Sac street and there are 40+ kids all under age of 12 living on the street. Lots of kids, low crime, no evidence of any gangs, newer construction, field of dreams type baseball/soccer/roller hockey/swimming/basketball complex. I know several families who could actually afford to live in, and in some cases moved from, much more exclusive areas (Rancho Santa Fe, La Jolla, etc.) who are living in 4S for the atomosphere, kid friendly community, and schools. As one person put it, how good is it for your kids if you live on a 2 acre gated estate in Rancho Santa Fe and your nearest neighbor with kids to play with your kids is hundreds of yards up the road in a similar “compound.” 4S is a great place to live if you have kids and can afford it. Wide price range of RE available from attached housing starting around $400,000 to gated homes on 1/2 acre lots at $1.5 milllion+
