Gwinnett ZIP codes — Gwinnett County, Georgia

Gwinnett County is a major city in Georgia, with 966,972 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 35.9 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Gwinnett County earn a median of $84,823 a year, 8% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 10.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Gwinnett County is valued at $345,700, 13.9% above the national figure, while median gross rent runs $1,713 a month, 21.8% above the national figure, or roughly $20,556 across a full year. A household on the local median income would put about 24.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 66.7% 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.
