ZIP 31638 in context

How this area compares with national benchmarks.

ZIP 31638 is a small town in Brooks County, Georgia, with 1,039 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #618 of 751 ranked by population — larger than 17% of them. The median age here is 44.1 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 31638 earn a median of $53,750 a year, 31.6% below 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 12.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 31638 is valued at $152,500, 49.7% below the national figure, while median gross rent runs $710 a month, 49.5% below the national figure, or roughly $8,520 across a full year. A household on the local median income would put about 15.9% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 76.1% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

Reading ZIP 31638 in context

How 31638 sits inside Brooks County and Georgia.

ZIP 31638 is tabulated inside Brooks County, Georgia, one of 6 ZIP areas the Census publishes for that county and 751 across Georgia. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 31638 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 31638 reports a median household income of $53,750, 13% below the $61,834 county median, and 13% below the $61,524 typical GA ZIP. Owner-occupied homes are valued at a median of $152,500, 55% above the county figure and 21% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $710 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 31638 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 31638 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.
