McDonough, Georgia

Henry County, Georgia · Population 29,051

McDonough sits at the geographic and political center of Henry County, about 30 miles south of downtown Atlanta along I-75. It serves as the county seat, which means the courthouse, county government, and much of the civic infrastructure anchor the town square. The historic square itself — ringed by storefronts, a 19th-century courthouse, and mature trees — is one of the more intact town centers in metro Atlanta's southern suburbs. What McDonough actually is, in practical terms, is a rapidly growing suburban city that absorbed decades of Atlanta sprawl while holding onto enough of its own identity to feel like somewhere specific. The population of 29,051 reflects that growth, and the median age of 31 tells you this is a young city — families, young professionals, and children everywhere.

People & Demographics

McDonough's 29,134 residents skew young, with a median age of 31.0 — well below the typical American city. Children under 18 account for 7,764 residents, a figure that puts consistent pressure on schools and youth services. The city is majority Black, with 21,131 residents identifying as Black, compared to 4,667 white residents and 539 Asian residents. The Hispanic and Latino population stands at 1,948.

The average household size is 2.92 people, and 6,760 of the city's 9,695 households are family households — a clear picture of a family-oriented community. Henry County as a whole has 240,712 residents, making McDonough home to roughly 12 percent of the county's population despite being the county seat.

Economy & Employment

The median household income in McDonough is $77,804, and per capita income sits at $32,712. Of the 15,915 residents in the labor force, 980 are unemployed — an unemployment rate of approximately 6.2 percent within the labor force. Poverty affects 2,943 residents.

Many working residents commute north to Atlanta or to industrial and distribution centers along the I-75 corridor in Henry County. The county's location along one of the Southeast's busiest freight corridors has attracted warehousing and logistics operations, which generate significant employment in the area.

Housing

McDonough has 10,410 total housing units. Of those, 9,695 are occupied and 715 sit vacant — a vacancy rate of about 6.9 percent, relatively low for a growing suburb. The owner-renter split is nearly even: 4,836 owner-occupied units and 4,859 renter-occupied units. That near-parity is unusual and suggests the rental market here is substantial.

The median home value is $246,800, and median gross rent is $1,441 per month. For comparison, both figures are consistent with outer-ring Atlanta suburbs — more affordable than Atlanta proper or the northern suburbs, but no longer the bargain it was a decade ago.

Schools

McDonough is served by Henry County Schools, one of Georgia's larger school districts. The city and surrounding area support a dense network of schools at every level.

High Schools: - Ola High School — Grades 9–12, 1,764 students - Union Grove High — Grades 9–12, 1,648 students - Eagle's Landing High School — Grades 9–12, 1,642 students - McDonough High School — Grades 9–12, 1,288 students

Middle Schools: - Ola Middle School — Grades 6–8, 1,163 students - Eagle's Landing Middle School — Grades 6–8, 1,092 students - Union Grove Middle — Grades 6–8, 1,069 students - McDonough Middle School — Grades 6–8, 954 students

Elementary Schools: - Oakland Elementary — 931 students - Ola Elementary — 913 students - Wesley Lakes Elementary — 843 students - Tussahaw Elementary — 802 students - Timber Ridge Elementary — 761 students - Walnut Creek Elementary — 716 students - East Lake Elementary — 710 students

The combined high school enrollment across all four schools exceeds 6,300 students, which reflects how much Henry County has grown. These are large schools by any measure.

Getting Around

McDonough is car country. Of 14,135 total workers, 10,917 drive alone to work and 1,118 carpool. Only 110 use public transit. A notable 1,700 workers — about 12 percent — work from home. Just 223 walk to work.

The aggregate commute time across all workers is 383,300 minutes, which works out to an average one-way commute of roughly 27 minutes. For a city 30 miles from Atlanta, that's reasonable when traffic cooperates on I-75, which it often does not during peak hours. Anyone without a car will find the city genuinely difficult to navigate.

Healthcare

Piedmont Henry Hospital serves as the primary hospital for McDonough and Henry County. The facility is located within the county and handles emergency and inpatient care for the region.

Parks & Recreation

For a city with limited municipal park infrastructure relative to its population size, these NPS units provide meaningful outdoor recreation options within an hour's drive.

Natural Hazards

Henry County has a long FEMA declaration history, and it covers most categories of natural disaster a Georgia county can face.

Severe winter storms have triggered emergency declarations in 1993, 2000, 2014, and again in January 2026 — the ice and snow vulnerability of metro Atlanta's southern suburbs is real and recurring. Tornado and severe storm events produced declarations in 1990, 1994, and January 2023, the last of which involved straight-line winds and tornado damage. Tropical weather has reached Henry County in the form of Tropical Storm Alberto (1994), Hurricane Irma (2017, which generated two separate declarations), and Hurricane Helene (September 2024). The county also served as a staging area during Hurricane Katrina evacuations in 2005. Flooding declarations have appeared repeatedly across the decades.

Anyone moving to McDonough should carry comprehensive homeowners insurance, take winter weather warnings seriously (the city has limited snow removal infrastructure), and monitor the National Weather Service forecast and active weather alerts for the area. The nearest official weather observation station is MCDONOUGH 1.7 NW, located 1.3 miles from the city center.

Government & Municipal Code

McDonough's municipal code is published through Municode and is publicly accessible at library.municode.com/ga/mcdonough. The city does not maintain a separate municipal building code in its code repository — construction and permitting standards may rely on state-level or county-level codes, and prospective builders should confirm current requirements directly with the city's building or planning department.
