Boston Nextdoor Ads Audience: Age, Gender, Unknown Share, and Interest Targeting Ranges
Nextdoor Audience in Boston, MA: 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 Boston is 68,000. A meaningful share of that total sits in Unknown age (11,900, about 17.5%), so the cleanest way to read the age profile is to separate “known-age” users from the Unknown bucket. Within the known-age portion (56,100), the audience is clearly older-skewing, with 55+ accounting for 32,000 (about 57.0% of known-age reach).
Gender composition also stands out. Female reach is 37,000 (about 54.4% of total) versus 22,000 male (about 32.4%), with 9,000 Unknown gender (about 13.2%). Among users with known gender (59,000), the split is about 62.7% female and 37.3% male. Unknown is not confined to one dimension: within the Unknown gender segment, 3,200 (about 35.6%) also have Unknown age, which limits how precisely demographic conclusions can be generalized across the full local audience.

Nextdoor Interest Segments in Boston, MA: 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 Boston market versus which are more niche.
Boston shows the strongest scale in home and household-intent categories, with broad ranges in segments like Home Improvement & DIY (34,000–198,000), Health (29,000–176,000), Pet Owners (28,000–170,000), and Lifestyles – Parents and Family (26,000–161,000). This can be a practical fit for local services, home-related offers, and community-driven demand where Nextdoor typically performs well.
Two segments are worth calling out for go-to-market planning. Small Business Decision Makers and Owners (3,000–23,000) can be a useful path to 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 (7,700–54,000) and Lifestyles – Parents and Family (26,000–161,000) can support parent-focused campaigns, but they represent a broad parent category without child-age details, which can complicate targeting for very specific parent subgroups and may require stronger creative qualification or landing-page filtering.
