North Decatur CDP, GA in context

How this area compares with national benchmarks.

North Decatur CDP is a mid-size town in Georgia, with 18,460 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #63 of 675 ranked by population — larger than 90% of them. The median age here is 39 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 North Decatur CDP earn a median of $110,366 a year, 40.5% above the national figure of $78,538 and 93% above the $57,300 median for the 378 Georgia cities we cover. 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in North Decatur CDP is valued at $459,000, 51.3% above the national figure and 140% above the $191,600 peer median, while median gross rent runs $1,750 a month, 24.5% above the national figure, or roughly $21,000 across a full year. A household on the local median income would put about 19% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 56.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
