Nextdoor audience in San Jose, CA: min monthly reach snapshot
This San Jose snapshot reflects the audience estimates available in the Nextdoor Ads interface for San Jose, CA, US.
The numbers below reflect minimum estimated monthly reach from the Nextdoor Ads interface. This is not a count of unique users. Think of it as a practical gauge of how much local scale you can plan around.
Demographics
San Jose’s Nextdoor audience here is just above 220,000 on the minimum estimate, giving advertisers a meaningful local footprint while still feeling more concentrated than the biggest metro snapshots. The profile is clearly older-leaning, with 55+ representing the largest share of the known-age audience. At the same time, the Unknown age portion remains large enough that the demographic picture should be read as directional rather than perfectly exact.
On gender, the audience skews female overall, while Unknown gender is still material enough to matter operationally. In practice, that means you can plan around a female-leaning mix, but you should still expect some fuzziness when layering age and gender too aggressively in campaign planning.
Nextdoor audience in San Jose, CA (Min Monthly Reach)

Interest segments
The interest table is best read as range planning. “Min” is your conservative baseline for likely scale, while “Max” shows how large the segment can become depending on how Nextdoor expands matching.
In San Jose, the most scalable buckets still lean toward home and lifestyle intent, especially home improvement, gardening, pet ownership, and health. Broad consumer categories such as automotive, finance, real estate, and travel also offer meaningful planning scale, making the mix practical for local services, home-related offers, and neighborhood-driven demand.
A few segments are especially worth watching. Declared Parents and Lifestyles - Parents and Family both show useful scale for family-oriented offers, though they remain broad audience signals rather than tightly qualified parent segments. Recent Mover - 6 Months is also notable because the gap between minimum and maximum reach is unusually wide, which makes it more useful for testing than for rigid forecasting. Small Business Decision Makers and Owners is narrower, but it can still be a helpful angle when you want local SMB exposure outside the usual LinkedIn and Meta workflows.
