Temecula and Murrieta have been opening new schools like mad for the last few years. People “drove to qualify” for new McMansions in the exurbs I guess. Also, the schools are pretty good up here so I think some people see a tradeoff between living in, say, Vista or Oceanside and sending their kids to private schools, or living in Temecula and sending their kids to the public school but having one parent suffer the commute.

I’ve read that San Francisco has seen declining public school enrollments for a number of years. SF public schools aren’t that great so people tend to move out to the burbs once they have kids.
