ZIP 73620 in context

How this area compares with national benchmarks.

ZIP 73620 is a small town in Custer County, Oklahoma, with 1,531 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #346 of 664 ranked by population — larger than 47% of them. The median age here is 39.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 73620 earn a median of $48,500 a year, 38.2% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 17% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 73620 is valued at $161,100, 46.9% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 68.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

The Census withheld gross rent for ZIP 73620 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 73620 in context

How 73620 sits inside Custer County and Oklahoma.

ZIP 73620 is tabulated inside Custer County, Oklahoma, one of 6 ZIP areas the Census publishes for that county and 664 across Oklahoma. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 73620 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 73620 reports a median household income of $48,500, 19% below the $59,665 county median, and 16% below the $57,827 typical OK ZIP. Owner-occupied homes are valued at a median of $161,100, 21% above the county figure and 25% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published 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 73620 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 73620 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.
