Having grown at an average rate of over one percent per year over the past decade, peaking at 1.7 percent in 2012, the estimated population of San Francisco proper inched up 0.3 percent in 2018, from a downwardly revised 880,980 at the start of last year to 883,869 as of January 1, 2019, according to the latest data from California’s Department of Finance.
That’s an estimated net population growth of 2,889 persons over the past year. And while that’s versus 2,579 net-new units of housing having been delivered in the city over the same period of time, keep in mind that the average unit in San Francisco houses 2.2 people.
Across the greater Bay Area, the estimated population grew by 31,810 (0.41 percent) in 2018 to 7,783,460, with Alameda County leading the way in the absolute (up 12,417 to 1,669,301) followed by Contra Costa County (up 8,000 to 1,155,879), with the populations in Sonoma and Napa having slipped post-wildfires and almost no change in Marin, as we’ve tabled below:

The estimated population growth rate for California was 0.47 percent last year, the slowest in the State’s history, “driven by a significant decline in births, down by more than 18,000 over the previous year, as well and data reflecting lower student enrollment.” At the same time, “deaths continued an upward trend seen since 2010 as California’s “Baby Boomers” continue to age.”
And of the ten largest cities in California, Sacramento recorded the largest percentage gain (1.49 percent) in population last year, increasing by 7,400 to 508,172.
