Grawn, MI (ZIP 49637) sits in Grand Traverse County within the Traverse City metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 6.5%. No NCES schools are mapped to this ZIP in the current dataset. 4 colleges and universities serve the area, with median in-state tuition of $9,430. IRS data shows average household income (AGI) of $68,545, well above the ~$45K national average per return. FEMA has issued 5 federal disaster declarations affecting this ZIP since 1977. Only 5.7% of residents under 65 are uninsured (County Health Rankings, 2025) — well below the national county median. 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. IRS migration data (2022-2023) shows a net gain of 679 residents (304 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 $74,088, fair market rent of $1,390 for a two-bedroom, and a typical home value of $342,411, up 2.7% 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.

What these numbers say together
Grawn, MI (ZIP 49637) sits in Grand Traverse County within the Traverse City metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 6.5%. No NCES schools are mapped to this ZIP in the current dataset. 4 colleges and universities serve the area, with median in-state tuition of $9,430. IRS data shows average household income (AGI) of $68,545, well above the ~$45K national average per return. FEMA has issued 5 federal disaster declarations affecting this ZIP since 1977. Only 5.7% of residents under 65 are uninsured (County Health Rankings, 2025) — well below the national county median. 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. IRS migration data (2022-2023) shows a net gain of 679 residents (304 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 $74,088, fair market rent of $1,390 for a two-bedroom, and a typical home value of $342,411, up 2.7% 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 higher the national rate at 27.0%. 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.

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
