The San Francisco Bay Area’s 50-year boom — Population growth, 1960-2010
“Like trees, cities can be thought of as adding growth rings every year. For most cities on this map, the outer ring represents the current population, from 2010 census data. The smallest, inner growth ring was the population in 1960. The largest cities of 1960 — San Francisco and Oakland - have larger inner rings. San Jose is a notable outlier, having swelled to consume the Valley of Heart’s Delight.”
