Gwinnett County is one of the largest, most diverse, and most economically powerful counties in Georgia — second only to Fulton in population, with ~1 million residents, the state's most diverse school district, and a meaningful share of metro Atlanta's tech corridor along Peachtree Industrial Boulevard. For relocators, the question isn't whether to consider Gwinnett — it's which Gwinnett city. Here's the complete guide.
Lawrenceville (the county seat)
Population ~32,000. Historic downtown square with a real revival underway (Aurora Theatre, restaurants, breweries). Mix of older neighborhoods around the square and newer subdivisions east toward Dacula. Gwinnett Technical College and Georgia Gwinnett College both inside the city. Median home price ~$385K. Strongest fit: first-time buyers wanting walkable downtown access without Suwanee or Duluth prices. [Movers in Lawrenceville →](/movers/lawrenceville)
Duluth
Population ~32,000. Walkable downtown along Main Street with a strong restaurant and bar scene (one of the most-improved suburban downtowns in metro Atlanta over the past decade). Substantial Korean-American community — Duluth's H Mart and Korean restaurants are destination-quality. Median home price ~$420K. Strong Peachtree Ridge feeder school zone in the northern parts. [Movers in Duluth →](/movers/duluth)
Suwanee
Population ~22,000. Consistently ranked among Georgia's best-places-to-live lists. Town Center on Main is a planned walkable downtown that genuinely works — restaurants, concerts, playground, real foot traffic. Top GCPS feeder zones (North Gwinnett, Peachtree Ridge, Collins Hill). Median home price ~$525K. Strongest fit: families willing to pay the premium for the best public schools in the county. [Movers in Suwanee →](/movers/suwanee)
Sugar Hill
Population ~25,000. Newer planned downtown (The Bowl outdoor amphitheater, EpiCenter civic complex) — Sugar Hill has invested heavily in building a town center it didn't have a decade ago. Lambert High School feeder (one of Georgia's top-rated). Median home price ~$465K. Strongest fit: families wanting Lambert schools without paying Forsyth County prices. [Movers in Sugar Hill →](/movers/sugar-hill)
Buford
Population ~17,000. Distinct because of Buford City Schools — a small, separately administered district that consistently ranks among Georgia's top public school systems. Mall of Georgia anchors the commercial core. Lake Lanier access. Median home price ~$485K. Strongest fit: families specifically targeting Buford City Schools or wanting Lake Lanier proximity. [Movers in Buford →](/movers/buford)
Peachtree Corners
Population ~46,000. Gwinnett's wealthiest incorporated city. Technology Park and Curiosity Lab anchor a real tech-corridor economy. The Forum (open-air retail center) is the social anchor. Median home price ~$575K. Strongest fit: tech professionals wanting Gwinnett pricing with strong commute access to North Fulton or up I-285. [Movers in Peachtree Corners →](/movers/peachtree-corners)
Norcross
Population ~17,000. Historic downtown with one of the best small-city restaurant scenes in metro Atlanta — Norcross Station, Tannery Row, several genuine destination restaurants. Strong Latino and Asian-American communities. Median home price ~$415K. Strongest fit: foodies and young families wanting walkable historic-downtown character at sub-Decatur prices. [Movers in Norcross →](/movers/norcross)
Lilburn
Population ~13,000. Small historic downtown along Old Town. Strong Korean and South Asian communities — the BAPS Shri Swaminarayan Mandir (Hindu temple) is one of the largest in North America. Median home price ~$355K. Strongest fit: first-time buyers wanting Gwinnett with shorter commutes than Suwanee/Dacula.
Snellville
Population ~21,000. Brookwood and South Gwinnett feeder zones — Brookwood High is consistently top-tier. Suburban character, lots of newer subdivisions. Median home price ~$385K. Strongest fit: families targeting Brookwood schools at south-Gwinnett prices. [Movers in Snellville →](/movers/snellville)
Grayson
Population ~5,000 but the broader Grayson area is much larger. Grayson High School (a top-tier GCPS school with a perennial football program). Newer subdivisions dominate. Median home price ~$410K. Strongest fit: families specifically targeting Grayson High. [Movers in Grayson →](/movers/grayson)
Hamilton Mill, Mill Creek area (unincorporated Dacula)
Not a city, but worth mentioning — Mill Creek High School is among GCPS's top feeders, and Hamilton Mill is one of Gwinnett's premier master-planned communities. Median home price in the broader area ~$575K.

Gwinnett County contains 16 incorporated cities: Lawrenceville (county seat), Duluth, Suwanee, Sugar Hill, Buford, Peachtree Corners, Norcross, Lilburn, Snellville, Grayson, Loganville (shared with Walton County), Auburn (shared with Barrow County), Berkeley Lake, Braselton (shared), Dacula, and Rest Haven. Several large unincorporated communities — Centerville, Mountain Park, and parts of Hamilton Mill — also have distinct identities.
Gwinnett is the second-most-populous county in Georgia (~1 million residents) and consistently ranks among the most diverse counties in the Southeast. Public schools (Gwinnett County Public Schools, GCPS) are large and mid-to-upper tier statewide, with strong magnet programs. Housing values run the full range — from $250K starter homes in Norcross/Lilburn to $1M+ estates in Suwanee and Hamilton Mill.
Commute to Atlanta is the main trade-off (45+ minutes to downtown during rush hour from most of the county).
Peachtree Corners and Suwanee consistently rank as the wealthiest incorporated cities in Gwinnett by median household income (both above $130K). The Hamilton Mill and Sugarloaf areas (parts of Dacula and Duluth) are also among Gwinnett's highest-income communities, with luxury subdivisions and top-feeder schools.
The strongest GCPS feeder zones are Peachtree Ridge (Suwanee), Mill Creek (Hoschton/Hamilton Mill), Brookwood (Snellville), Collins Hill (Suwanee), and North Gwinnett (Suwanee). Suwanee dominates the top-feeder list. Buford City Schools (a separate small district inside Gwinnett, not GCPS) is also consistently top-rated statewide.
