Madison, GA (ZIP 30650) sits in Morgan County within the Atlanta-Sandy Springs-Roswell metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 40.2%. NCES lists 4 schools serving the area, 4 non-charter. 6 colleges and universities serve the area, with median in-state tuition of $9,050. IRS data shows average household income (AGI) of $87,839, well above the ~$45K national average per return.

IRS migration data (2022-2023) shows a net gain of 367 residents (81 households) — the ZIP's primary county is growing. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over.

Madison, GA (ZIP 30650) sits in Morgan County within the Atlanta-Sandy Springs-Roswell metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 40.2%.

IRS data shows average household income (AGI) of $87,839, well above the ~$45K national average per return. BLS QCEW reports average annual pay of $51,852 per worker, roughly 21% below the US average. FEMA has issued 22 federal disaster declarations affecting this ZIP since 1973 — a high-frequency exposure profile. Annual precipitation averages 51.2" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. 34.6% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Georgia levies a flat state income tax (top rate 5.39%); a household at the local median AGI of $87,839 would pay roughly $2,841/year before deductions. IRS migration data (2022-2023) shows a net gain of 367 residents (81 households) — the ZIP's primary county is growing. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $80,276, fair market rent of $1,450 for a two-bedroom, and a typical home value of $443,040, up 3.7% 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 19.2%. 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.
