North Decatur, Georgia

DeKalb County, Georgia · Population 18,511

North Decatur is an unincorporated community — technically a Census Designated Place — sitting just inside the northern arc of DeKalb County, wedged between the city of Decatur to the south and the busier commercial corridors pushing toward I-285. It reads as a quiet, established suburb: tree-lined streets, modest ranch homes alongside larger renovated properties, and a resident population that skews educated and settled. It has no city government of its own, which means DeKalb County handles services, zoning, and code enforcement. For most daily needs, residents pull from both the City of Decatur and Atlanta proper, both of which are minutes away.

People & Demographics

North Decatur holds 17,183 residents by ACS estimate, with a median age of 40.2 — older than most of DeKalb County's 764,382-person population, which trends younger in its more urban pockets. The community is majority white (11,255), with Black residents numbering 2,586, Asian residents 1,790, and 1,005 residents identifying as Hispanic or Latino.

Household structure here is relatively compact. There are 8,066 occupied households, of which 3,902 are family households, and the average household size is 2.11 — well below the national average, reflecting a high proportion of couples without children and single-person households. Children under 18 number 2,923, meaning roughly 17% of the population.

Economy & Employment

The median household income in North Decatur is $103,468 — substantially above Georgia's statewide median and a clear marker of an affluent suburban enclave. Per capita income sits at $65,842. Of the 9,948 residents in the labor force, 449 are unemployed, an unemployment rate of approximately 4.5%. Despite the relative wealth of the community, 1,665 residents fall below the poverty line — a reminder that income inequality exists even in higher-income places.

Housing

North Decatur's housing stock totals 9,328 units, with 8,066 occupied and 1,262 vacant. The split between owners and renters is relatively even: 4,623 owner-occupied units against 3,443 renter-occupied — roughly 57% versus 43%. That renter share is higher than many comparable suburbs and reflects both the proximity to universities and Emory's medical corridor.

The median home value is $410,800, which places North Decatur firmly at the higher end of DeKalb County's housing market. Renters pay a median of $1,609 per month. Neither figure is affordable for someone earning a typical Georgia wage, but they're consistent with the community's income profile.

Schools

North Decatur falls within the DeKalb County School District, and high school students in this area are commonly zoned for Lakeside High School (2,141 students, grades 9–12) or Chamblee High School (1,776 students, grades 9–12), with the broader district also operating Tucker High School (1,579 students), Cross Keys High School (1,714 students), and Lithonia High School (1,483 students).

Middle school students may attend Sequoyah Middle School (1,763 students, grades 6–8) or Willis A. Sutton Middle School (1,548 students, grades 6–8).

The district also enrolls students in Georgia Cyber Academy (8,876 students, grades K–12), a statewide online public school. Nearby city districts include Decatur High School (1,853 students) within the City of Decatur's independent system, and Atlanta Public Schools serves North Atlanta High School (2,316 students) and Midtown High School (1,602 students) just across the county line. Riverwood International Charter School (1,737 students) in Sandy Springs draws competitive applicants from this area as well.

Getting Around

Of 9,438 workers, 5,889 drive alone — about 62%. Another 813 carpool. Public transit accounts for 434 commuters, a meaningful number for a suburban CDP, reflecting MARTA bus access and proximity to rail. 222 residents walk to work, and 1,934 — just over 20% — work from home, above typical suburban averages.

Aggregate travel time for all workers totals 186,445 minutes, which averages to roughly 19.8 minutes per commuter. Atlanta's core is close enough that peak-hour traffic is a real factor, but not brutal compared to outer-ring suburbs.

Healthcare

North Decatur sits within close reach of one of the densest medical corridors in the Southeast. Emory University Hospital and Emory Decatur Hospital are both within a few miles. Morehouse School of Medicine (404-752-1500) is located nearby and operates community health programs in addition to its academic mission. For a searchable list of individual healthcare providers registered in North Decatur, the CMS NPI Registry provides current provider data.
