Reading Castro Valley, CA beyond the headline numbers

Castro Valley sits inside Alameda County, California, at roughly 37.69°N, -122.09°W. Its population of 61,388 and $142,779 median household income are the two most quoted figures, but in isolation they hide the shape of the city.

The 6.7% poverty rate next to that income figure is the better signal, two cities with identical medians can have very different lived realities depending on the income distribution underneath.
