Cobb County · Atlanta-Sandy Springs-Roswell, GA · Population 34,331
Marietta, GA (ZIP 30008) sits in Cobb County within the Atlanta-Sandy Springs-Roswell metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in above the national average at 19.9%. NCES lists 4 schools serving the area, 4 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $15,036. 24% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. Federal QCEW filings show 384,275 covered jobs in this ZIP's primary county — a major regional employment hub. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2026). 38.9% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Per IRS migration filings (2022-2023), the area's primary county lost $270,433,000 in net taxable income to other counties. Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: median household income $68,218, fair market rent of $1,660 for a two-bedroom, and a typical home value of $327,798, down 3.1% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits lower the national rate at 18.3%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
