Gilbertville is a small Iowa community in Black Hawk County, about 5 miles southeast of Waterloo.

The numbered street grid (5th Street, 6th Street, numbered avenues) gives Gilbertville the layout of an established small town.
This is a PO Box Only Zone. No alternative mail delivery exists. The post office maintains 365 PO Boxes for 339 households, meaning PO Box adoption slightly exceeds local housing (1.08x rate). That pattern shows the post office serves not just Gilbertville residents but also people from the surrounding rural area who lack other mail access.
Rural carrier route delivery operates here, with 137 delivery points served by one rural route. This isn't city carrier delivery with daily walking routes. It's rural delivery covering the town and adjacent areas. Street names like Gilbertville Road, Indian Creek Road, and Prairie Lane connect to the agricultural landscape beyond town limits.
Gilbertville leans older and settled. Median age is 44.5 years. Homeownership dominates at 87% (294 of 339 households). Median home values of $187,500 and median household income of $83,750 place this town above Iowa's rural averages. Nearly one in five workers (19%) work from home, a pattern that's become common in small towns within commuting distance of larger cities like Waterloo.
The town is 95% white (757 of 795 residents), with a growing Hispanic population of 118 people. All residents were born in the United States. Just over a quarter of adults (26%) hold bachelor's degrees or higher. Eleven businesses employ 42 people locally, but many residents commute. Transportation and warehousing employ 308 workers, likely reflecting jobs in the Waterloo metro area.
