Windham County · Population 5,082
Canterbury, CT (ZIP 06331) sits in Windham County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in below the national average at 6.5%. NCES lists 2 schools serving the area, 2 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $29,315. IRS data shows average household income (AGI) of $80,584, well above the ~$45K national average per return. Local establishments report average pay of $33,993 per worker (Census ZBP) — below the US average. 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. FEMA has issued 32 federal disaster declarations affecting this ZIP since 1978 — a high-frequency exposure profile. Annual precipitation averages 52.2" — a wet-climate ZCTA per NOAA's 1991–2020 Normals. Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. Connecticut levies a graduated state income tax (top rate 6.99%); a household at the local median AGI of $80,584 would pay roughly $3,380/year before deductions. 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 $96,126, fair market rent of $1,680 for a two-bedroom, and a typical home value of $405,277, up 5.2% 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.
