Top health signal: High Blood Pressure comes in above the national average at 44.4%. No NCES schools are mapped to this ZIP in the current dataset. 7 colleges and universities serve the area, with median in-state tuition of $13,201. IRS data shows average household income (AGI) of $272,340, well above the ~$45K national average per return. Social vulnerability is low in this ZIP at the 9th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters.

Georgia levies a flat state income tax (top rate 5.39%); a household at the local median AGI of $272,340 would pay roughly $8,807/year before deductions. Per IRS migration filings (2022-2023), the area's primary county netted $147,011,000 in incoming taxable income — a wealth-inflow signal even when headcount churn is modest. 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 $119,670, fair market rent of $2,150 for a two-bedroom, and a typical home value of $904,733, up 0.2% 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 15.6%. 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.
