Marquette sits on the Mississippi River in Clayton County, Iowa, a small town where PO Boxes are the only mail delivery option across its 1.31 square mile territory. With 273 residents and 128 households, the post office maintains 154 PO Boxes. That's 1.2 boxes per household, showing this office serves surrounding rural areas beyond the town limits.
The town layout follows a classic numbered grid. North Street has the most delivery points (15 records), followed by numbered streets like 1st, 2nd, 3rd, and 5th. One standout: Antimonopoly Street, a name that hints at late 19th-century political movements. Streets also include Water Street (likely near the riverfront), Brown Street, and Green Street.
This is a PO Box Only Zone, meaning there's no alternative mail delivery anywhere in the area. The ZIP has one rural carrier route serving 80 delivery points, but PO Box pickup remains the primary option for residents. General Delivery is also available for those without a box.
Marquette's demographics show an established, working-class community. Median age is 45.4 years, with homeownership at 80% (103 owner-occupied of 128 total households). Median household income sits at $44,107, with median home values around $132,800. The town has 11 business establishments employing 315 people. That's more workers than residents, indicating Marquette draws employees from surrounding areas.
Nearly all residents (98%) work outside the home. Transportation and warehousing employ the most workers (123 people), suggesting the Mississippi River location supports logistics or manufacturing. Educational services and healthcare employ 49 workers. Only 6 people (13.4%) work from home, lower than Iowa's rural average. About half (50 workers) drive alone to work, while 24 carpool and 18 use public transit or other methods.
The housing stock is old. Of 188 total units, 189 were built before 1939, meaning virtually every structure dates back at least 85 years. That makes Marquette one of Iowa's better-preserved small river towns. Seasonal vacancy is low: only 27 of 188 units (14%) are seasonal or occasional use. This is a year-round community, not a vacation destination.
