Bureau, IL

ZIP code 61315 is assigned to Bureau, IL, and falls within Bureau 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 279 people live inside it.

At 224 residents per square mile spread over 1.246 square miles, 61315 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 $54,063, 61315 sits in the lower half, ahead of 22% 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 61315 costs well below the national median. A typical home is valued at $53,700 against a US median of $207,500, and median gross rent runs $1,821 a month. The split between owning and renting is fairly even at 59.1% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by detached single-family houses, which account for 89.4% of housing units here. The median construction year is 1951, making the housing here mid-century. The vacancy rate of 22.5% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews broadly in line with the national age profile, with a median age of 36.5 against 42 nationally. The average household holds 2.54 people, and 61.8% are family households.

Getting to work takes 37.0 minutes on average one way. The dominant mode is drove alone at 85.9% of workers.

Beyond addressing mail, 61315 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, 61315 offers a compact profile of Bureau: 279 residents, a median household income of $54,063, 6.1% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.1%. 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. 61315 may cover parts of several distinct areas, and a single neighbourhood in Bureau 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.
