  1. The Oakland and San Jose living wages were adopted in 1998, and San Francisco’s in 2000. The living wage variables are averaged over months in a year. The MSA/PMSA living wage sometimes shows small deviations before there is a living wage because the table reports the average minimum wage (or living wage, if there is one), the state minimum wage can change mid-year, and the sample proportions in different months can vary across areas.
