Fresh.Data current as of Apr 24, 2026
Binford, ND (ZIP 58416) sits in Griggs County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 41.3%. NCES lists 1 schools serving the area, 1 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $22,345. IRS data shows average household income (AGI) of $82,756, well above the ~$45K national average per return. Local establishments report average pay of $32,185 per worker (Census ZBP) — below the US average. BLS LAUS reports county unemployment of just 2.3% (2024), well below the ~4.0% US average and consistent with a tight local labor market. 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 23 federal disaster declarations affecting this ZIP since 1966 — a high-frequency exposure profile. Annual average temperature is just 40.4°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. 32.8% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. North Dakota levies a flat state income tax (top rate 2.50%); a household at the local median AGI of $82,756 would pay roughly $1,241/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 $57,500, fair market rent of $1,000 for a two-bedroom, and a typical home value of $121,597, down 8.9% 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
Binford, ND (ZIP 58416) sits in Griggs County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 41.3%. NCES lists 1 schools serving the area, 1 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $22,345. IRS data shows average household income (AGI) of $82,756, well above the ~$45K national average per return. Local establishments report average pay of $32,185 per worker (Census ZBP) — below the US average. BLS LAUS reports county unemployment of just 2.3% (2024), well below the ~4.0% US average and consistent with a tight local labor market. 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 23 federal disaster declarations affecting this ZIP since 1966 — a high-frequency exposure profile. Annual average temperature is just 40.4°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. 32.8% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. North Dakota levies a flat state income tax (top rate 2.50%); a household at the local median AGI of $82,756 would pay roughly $1,241/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 $57,500, fair market rent of $1,000 for a two-bedroom, and a typical home value of $121,597, down 8.9% 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 18.7%. 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.
