ZIP code 73018

ZIP 73018 is a mid-size town in Grady County, Oklahoma, with 20,393 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #64 of 664 ranked by population — larger than 90% of them. The median age here is 38.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 73018 earn a median of $58,340 a year, 25.7% below the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 17.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 73018 is valued at $126,600, 58.3% below the national figure, while median gross rent runs $877 a month, 37.6% below the national figure, or roughly $10,524 across a full year. A household on the local median income would put about 18% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.2×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 59.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

ZIP 73018 is tabulated inside Grady County, Oklahoma, one of 11 ZIP areas the Census publishes for that county and 664 across Oklahoma. This is a mid-sized ZIP that covers a large share of its county's addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 73018 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 73018 reports a median household income of $58,340, 13% below the $67,422 county median, and close to the $57,827 typical OK ZIP. Owner-occupied homes are valued at a median of $126,600, close to the county figure and close to the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $877 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Oklahoma charges 4.5% statewide, and local governments overlapping 73018 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 73018 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
