Overview

Understanding ZIP code 50518

ZIP code 50518 is assigned to Barnum, IA, and falls within Webster 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 366 people live inside it.

At 13 residents per square mile spread over 28.868 square miles, 50518 reads as a rural 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 above the national median. At $84,830, 50518 sits comfortably in the upper half, ahead of 71% 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 Barnum looks like

Housing in 50518 costs below the national median. A typical home is valued at $144,200 against a US median of $207,500, and median gross rent runs $495 a month. Ownership dominates: 93.3% 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 94.4% of housing units here. The median construction year is 1988, making the housing here from the later twentieth century.

The population skews notably young, with a median age of 27.8 against 42 nationally. The average household holds 2.71 people, and 78.5% are family households.

Getting to work takes 20.1 minutes on average one way. The dominant mode is drove alone at 75.8% of workers.

Where to stay

Where to stay in Barnum, IA

50518 covers a rural area, and accommodation within the postal code itself is likely to be sparse — perhaps a country inn, a lodge or a vacation rental rather than a conventional hotel. Widening the search radius is usually the practical approach, and it also opens up more availability at short notice.

Local costs are modest — median rent here is $495 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Chicago, IL is about 348.3 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 50518 is used for

Beyond addressing mail, 50518 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, 50518 offers a compact profile of Barnum: 366 residents, a median household income of $84,830, 3.3% of adults holding a bachelor's degree or higher, and an unemployment rate of 2.6%. 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. 50518 may cover parts of several distinct areas, and a single neighbourhood in Barnum 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.

Does 50518 cover more than one city or county?
This page lists Barnum as the primary place and Webster County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 50518 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
