Nextdoor Audience in San Francisco: Estimated Monthly Reach (Min Monthly Reach)
The figures below reflect minimum estimated monthly reach from the Nextdoor Ads interface. This is not a count of unique users. The goal is to understand local addressable scale and the age, gender, and Unknown distribution inside the minimum reach forecast.
The total minimum estimated monthly reach in San Francisco is 181,000. A meaningful share of that total sits in Unknown age (34,500, about 19.1%), so the cleanest way to read the age profile is to separate “known-age” users from the Unknown bucket. Within the known-age portion (146,500), the audience is clearly older-skewing, with 55+ accounting for 72,000 (about 49.1% of known-age reach).
Gender composition also stands out. Female reach is 100,000 (about 55.2% of total) versus 62,000 male (about 34.3%), with 19,000 Unknown gender (about 10.5%). Among users with known gender (162,000), the split is about 61.7% female and 38.3% male. Unknown is not confined to one dimension: within the Unknown gender segment, 6,200 (about 32.6%) also have Unknown age, which limits how precisely demographic conclusions can be generalized across the full local audience.

Nextdoor Interest Segments in San Francisco: Min vs Max Monthly Reach
The interest ranges below show potential monthly reach using a conservative minimum estimate and a higher maximum estimate. Practically, this is a quick way to see which interests can scale broadly in the San Francisco market versus which are more niche.
San Francisco shows especially large scale in home and household-intent categories, with wide ranges in segments like Home Improvement & DIY (82,000–420,000), Gardening & Landscape (68,000–359,000), Pet Owners (67,000–355,000), and Health (64,000–341,000). This is often a strong fit for local services, home-related offers, and community-driven demand.
Two segments are worth calling out for go-to-market planning. Small Business Decision Makers and Owners (6,600–47,000) can be a practical way to reach local SMB audiences, where access may be more competitive or more expensive on platforms like LinkedIn and other major networks. Parents and families segments such as Declared Parents (30,000–180,000) and Lifestyles – Parents and Family (58,000–314,000) can support parent-focused campaigns, but they reflect a broad parent category without child-age details, which can complicate targeting for specific parent subgroups and may require stronger creative qualification or landing-page filtering.
