Overview

Understanding ZIP code 50842

ZIP code 50842 is assigned to Cromwell, IA, and falls within Union 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 85 people live inside it.

At 329 residents per square mile spread over 0.258 square miles, 50842 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 run below the national median. At $57,917, 50842 sits in the lower half, ahead of 29% 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.

Living here

What life in Cromwell looks like

Housing in 50842 costs below the national median. A typical home is valued at $108,900 against a US median of $207,500. Ownership dominates: 89.2% 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 85.0% of housing units here. The median construction year is 1975, making the housing here from the later twentieth century.

Getting to work takes 20.2 minutes on average one way. The dominant mode is drove alone at 72.5% of workers.

Where to stay

Where to stay in Cromwell, IA

Cromwell is a smaller community, so options inside 50842 may be limited to a handful of independent inns, motels or bed-and-breakfast properties. Travellers often widen the search to the surrounding area, where the choice is greater and prices are usually competitive.

For reference, Chicago, IL is about 358.4 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses

What ZIP code 50842 is used for

Beyond addressing mail, 50842 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, 50842 offers a compact profile of Cromwell: 85 residents, a median household income of $57,917, 15.3% 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. 50842 may cover parts of several distinct areas, and a single neighbourhood in Cromwell 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.

For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
