Overview

Understanding ZIP code 51363

ZIP code 51363 is assigned to Superior, IA, and falls within Dickinson 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 132 people live inside it.

At 311 residents per square mile spread over 0.424 square miles, 51363 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 $59,432, 51363 sits in the lower half, ahead of 31% 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 Superior looks like

Housing in 51363 costs well below the national median. A typical home is valued at $74,000 against a US median of $207,500. Ownership dominates: 98.2% 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 97.1% of housing units here. The median construction year is 1943, making the housing here largely pre-war.

The population skews older than the national median, with a median age of 47.4 against 42 nationally. The average household holds 2.32 people, and 73.7% are family households.

Getting to work takes 23.4 minutes on average one way. The dominant mode is drove alone at 94.9% of workers.

Where to stay

Where to stay in Superior, IA

Superior is a smaller community, so options inside 51363 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 386.9 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 51363 is used for

Beyond addressing mail, 51363 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, 51363 offers a compact profile of Superior: 132 residents, a median household income of $59,432, 6.9% of adults holding a bachelor's degree or higher, and an unemployment rate of 6.3%. 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. 51363 may cover parts of several distinct areas, and a single neighbourhood in Superior 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.

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.
