Grain Valley, MO

ZIP code 64029 is assigned to Grain Valley, MO, and falls within Jackson 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 21,643 people live inside it.

At 680 residents per square mile spread over 31.823 square miles, 64029 reads as a small-town area. It is a mid-sized postal code by population, 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 $89,074, 64029 sits comfortably in the upper half, ahead of 75% 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 64029 costs close to the national median. A typical home is valued at $284,700 against a US median of $207,500, and median gross rent runs $1,369 a month. Ownership dominates: 72.4% 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 90.3% of housing units here. The median construction year is 2001, making the housing here relatively modern.

The population skews broadly in line with the national age profile, with a median age of 37.2 against 42 nationally. The average household holds 2.79 people, and 71.5% are family households.

Getting to work takes 28.0 minutes on average one way. The dominant mode is drove alone at 78.8% of workers, while 16.2% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 64029 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, 64029 offers a compact profile of Grain Valley: 21,643 residents, a median household income of $89,074, 30.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 1.7%. 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. 64029 may cover parts of several distinct areas, and a single neighbourhood in Grain Valley 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.
