Boise City, ID (ZIP 83702) sits in Ada County within the Boise City metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in below the national average at 7.5%. NCES lists 9 schools serving the area, 9 non-charter. 8 colleges and universities serve the area, with median in-state tuition of $11,802. IRS data shows average household income (AGI) of $173,526, well above the ~$45K national average per return. Census ZBP marks the area as a major commercial hub with 2,119 business establishments. Federal QCEW filings show 288,010 covered jobs in this ZIP's primary county — a major regional employment hub. FEMA has issued 8 federal disaster declarations affecting this ZIP since 1964. 30.4% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. IRS migration data (2022-2023) shows a net gain of 3,638 residents (2,399 households) — the ZIP's primary county is growing. Healthcare access and school options both run strong here, giving residents a wide menu of providers and enrollment choices nearby. Notable: median household income $77,115, fair market rent of $1,660 for a two-bedroom, and a typical home value of $722,148, up 3.2% 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.
These two readings tell a consistent story. Strong access numbers usually correlate with denser provider networks, and a high school count signals the population base that supports them. Reading them together: a household weighing this ZIP for a multi-year stay can expect both healthcare and education infrastructure to keep pace.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 25.5%. 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.
