Sunnyvale Among Bay Area’s Faster-Growing Cities
- California’s May 1 population release showed Sunnyvale grew in 2025, putting it among the Bay Area cities still adding residents as the state slipped. - The bigger Bay Area standouts were Santa Clara and Burlingame, which landed on the state’s fastest-growing list for cities above 30,000 people. - That matters because California overall fell 0.14% in 2025 after immigration slowed sharply.
City population data can sound dry, but this one says something real about where the Bay Area is still pulling people in. California’s new January 1, 2026 estimates show the state slipped slightly in 2025, yet a few Peninsula and South Bay cities kept growing anyway. Sunnyvale is one of them. Santa Clara and Burlingame grew even faster, enough to make the state’s list of quickest-growing larger cities. (dof.ca.gov) ### What actually came out? The California Department of Finance released its annual city, county, and state population estimates on May 1. These are the official planning numbers California uses for budgeting and local government calculations, and they compare January 1, 2025 with January 1, 2026. The state says California lost about 54,000 residents over that span, a 0.14% dip. (dof.ca.gov) ### Where does Sunnyvale fit? Sunnyvale grew while the statewide number moved the other way. That is the basic reason it stands out. The Bay Area has plenty of places still dealing with expensive housing, slower office demand, and the long aftereffects of pandemic-era migration shifts, so any city posti(dof.ca.gov)still adding residents rather than treading water or shrinking. (mercurynews.com) ### Why are Santa Clara and Burlingame getting more attention? Because they were not just up — they were up enough to rank among California’s fastest-growing cities with populations above 30,000. That is a more selective list than just saying a city grew. It means these two outpaced most comparable cities in th(mercurynews.com) of the release. (mercurynews.com) ### So why did California shrink at all? The short version is immigration changed fast. The Finance Department says restrictive federal policy changes cut legal international migration to California by more than half in 2025 — from 248,400 in 2024 to 126,400 in 2025. That drop mattered because international mig(mercurynews.com)Once that cushion got smaller, the statewide total turned negative again. (dof.ca.gov) ### Why can Bay Area cities grow anyway? Because city growth is not the same as state growth. A city can add residents through new housing, local job demand, household crowding changes, or people moving short distances within the region even while California as a whole loses population. The state’s meth(dof.ca.gov) size, and group quarters. Basically — if a city is still adding places for people to live and still attracting workers, it can buck the broader trend. (dof.ca.gov) ### Is this mostly a housing story? A lot of it is. The Finance Department’s city estimates are built with the housing unit method, which starts with additions and losses to housing stock. That does not mean jobs and schools do not matter — they do — but the mechanism in the estimate is closely tied to whether a city is physically makin(dof.ca.gov)ng, even modest construction can show up in the population numbers.

California had three straight years of population increases after the pandemic and then dipped again in 2025, so the bigger picture is still choppy. What this release really shows is that growth in the Bay Area is uneven now — concentra(dof.ca.gov)ce. (dof.ca.gov) ### Bottom line? Sunnyvale’s growth matters less as a bragging-rights stat than as a clue. Even in a year when California shrank, some Bay Area cities still had enough housing churn and economic pull to keep growing — and that is where the region’s next population gains are likely to cluster.
