What these numbers say together
GA 31318 (ZIP 31318) sits in Effingham County within the Savannah metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: High Blood Pressure comes in above the national average at 36.8%. No NCES schools are mapped to this ZIP in the current dataset. 1 college or university serves the area, with median in-state tuition of $8,256. The most recent FEMA disaster declaration here was hurricane-related (HURRICANE HELENE, 2024). Fast-food restaurants outnumber grocery stores roughly 10-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. IRS migration data (2022-2023) shows a net gain of 1,956 residents (789 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 $58,125, fair market rent of $1,430 for a two-bedroom, and a typical home value of $249,748, down 0.6% 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 near the national rate at 20.9%. 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.
