Saint Marys, IA

ZIP code 50241 is assigned to Saint Marys, IA, and falls within Warren County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 112 people live inside it.

At 794 residents per square mile spread over 0.141 square miles, 50241 reads as a small-town area. It is a sparsely populated postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings track close to the national picture. The median of $78,750 puts 50241 near the middle of the pack, ahead of 63% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Housing in 50241 costs below the national median. A typical home is valued at $168,800 against a US median of $207,500, and median gross rent runs $1,300 a month. Ownership dominates: 76.9% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 90.4% of housing units here. The median construction year is 1962, making the housing here mid-century. At 0.0%, vacancy is low — housing here is tightly held.

The population skews considerably older than the national median, with a median age of 53.5 against 42 nationally. The average household holds 2.15 people, and 61.5% are family households.

Getting to work takes 31.9 minutes on average one way. The dominant mode is drove alone at 80.6% of workers.

Beyond addressing mail, 50241 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 50241 offers a compact profile of Saint Marys: 112 residents, a median household income of $78,750, 23.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.0%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 50241 may cover parts of several distinct areas, and a single neighbourhood in Saint Marys may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
