The Politics Of California's Growth Are Daunting

"This massive movement of human beings and an equally impressive production of babies does not fall evenly on California. While immigrants tend to concentrate in urban areas - also the locale of most births - there's an offsetting shift of population from those urban centers into suburban and even rural areas. Thus, the state's fastest-growing regions are on the urban periphery, especially counties in the interior valleys north and south... These two trends mean that the fundamental impacts of growth - such as traffic and school crowding - are being felt most heavily in the suburbs, but the urban centers are undergoing a demographic transformation as immigrants settle in and others pack up for the suburbs."
