That's partly true, though the area right around the Redood City Caltrain (this uses census tracts, not the whole city) makes the difference much larger than if data for Redwood City as a whole was juxtaposed with Atherton as a whole. The area right around the Redwood City Caltrain is a bit sketchy, particularly on El Camino (the downtown on the other side is nicer). Not too sure why it hasn't gotten nicer, since it's so convenient to train service (30 mins from SoMA on the baby bullet Caltrain).
