Children Outnumber Seniors in All 18 North Atlanta Cities

Children outnumber seniors in every city covered by North Atlanta Star, but the size of that generational gap changes sharply from one community to the next.

The Census Bureau’s latest five-year community estimates put residents younger than 18 at 33.7% of Buford’s population, compared with 12.3% who are 65 or older. That 21.4-point difference is the widest among the 18 cities.

In incorporated Cumming, the two groups are much closer: children account for 18.9% of residents and seniors 16.5%, a difference of just 2.4 points.

Different demands on neighboring cities

Buford, Sugar Hill and Milton have the largest concentrations of children. Those age profiles can translate into sustained demand for schools, playgrounds, athletic fields, libraries and family-oriented events.

The three cities do not share one school system. Buford operates its own district, Sugar Hill is served by Gwinnett County Public Schools and Milton is part of Fulton County Schools. The figures therefore should not be treated as a school-enrollment ranking, but they help explain why youth services remain prominent across otherwise different communities.

At the other end of the comparison, Cumming and Sandy Springs are approaching a more even balance between children and seniors. Roswell has the next-highest senior share at 15.6%.

That creates a broader set of planning pressures: recreation for children alongside accessible parks, transportation, housing and social programs for residents who want to remain in their communities as they age.

Cumming’s figure applies only to the incorporated city, not the much larger South Forsyth area whose residents use Cumming mailing addresses. The distinction is especially important there because the city limits contain only a small portion of the population commonly associated with Cumming.

A survey estimate, not a current head count

The percentages come from the 2020–2024 American Community Survey, which combines five years of responses to produce estimates for communities of every size. They are separate from the Census Bureau’s annual July 2025 population estimates.

Smaller cities generally carry wider margins of error, so a difference of one or two percentage points should not be read as a precise ranking. The larger pattern is clearer: North Atlanta remains heavily shaped by families with children, even as several established suburbs prepare for a growing senior population.
