Stone Mountain, GA population, income and ZIP codes

Stone Mountain city is a mid-size town in Georgia, with 6,639 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #144 of 675 ranked by population — larger than 78% of them. The median age here is 34.4 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Stone Mountain city earn a median of $49,661 a year, 36.8% below the national figure of $78,538 and 13% below the $57,300 median for the 378 Georgia cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 15.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Stone Mountain city is valued at $190,700, 37.1% below the national figure and within a couple of points of the $191,600 peer median, while median gross rent runs $1,369 a month, 2.6% below the national figure, or roughly $16,428 across a full year. A household on the local median income would put about 33.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 52.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Stone Mountain city is the unusual combination of expensive to rent and cheap to buy: rent takes 33.1% of median income while homes cost only 3.8× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price.
