ZIP code 30518

ZIP 30518 is a small city in Gwinnett County, Georgia, with 56,309 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #33 of 751 ranked by population — larger than 95% of them. The median age here is 36.2 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 ZIP 30518 earn a median of $97,339 a year, 23.9% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 11.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 30518 is valued at $367,000, 21% above the national figure, while median gross rent runs $1,611 a month, 14.6% above the national figure, or roughly $19,332 across a full year. A household on the local median income would put about 19.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. 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. 76.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

ZIP 30518 is tabulated inside Gwinnett County, Georgia, one of 16 ZIP areas the Census publishes for that county and 751 across Georgia. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 30518 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 30518 reports a median household income of $97,339, 8% above the $90,277 county median, and 58% above the $61,524 typical GA ZIP. Owner-occupied homes are valued at a median of $367,000, 9% above the county figure and 89% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,611 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Georgia charges 4% statewide, and local governments overlapping 30518 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 30518 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
