ZIP code 31905

ZIP 31905 is a mid-size town in Chattahoochee County, Georgia, with 15,892 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #240 of 751 ranked by population — larger than 68% of them. The median age here is 22.6 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 31905 earn a median of $72,112 a year, 8.2% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 10.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 31905 is valued at not published, while median gross rent runs $1,600 a month, 13.8% above the national figure, or roughly $19,200 across a full year. A household on the local median income would put about 26.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. 0.6% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 22.6 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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 31905 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
