The quick read
Reading Alum Rock, CA beyond the headline numbers
Alum Rock sits inside Santa Clara County, California, at roughly 37.37°N, -121.83°W. Population 15,536, $126,705 median household income. Median home value $909,500, median rent $2,389. Poverty rate 6.2%, read against that income figure since two cities on the same median can differ underneath it.

The median home in Alum Rock costs around 7.2 times what a median household earns in a year -- the most expensive quarter of reporting cities, and far enough ahead of local pay that ownership is largely closed to median earners.
Only 7.7% of Alum Rock workers report working from home, the lowest quarter of reporting cities -- an economy still built around showing up somewhere.
