ZIP code 75173

ZIP 75173 is a mid-size town in Collin County, Texas, with 9,284 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #845 of 1,989 ranked by population — larger than 57% of them. The median age here is 36.4 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 75173 earn a median of $100,373 a year, 27.8% above 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 75173 is valued at $322,000, 6.1% above the national figure, while median gross rent runs $1,396 a month, essentially level with the national figure, or roughly $16,752 across a full year. A household on the local median income would put about 16.7% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 93.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 75173 is tabulated inside Collin County, Texas, one of 29 ZIP areas the Census publishes for that county and 1,989 across Texas. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 75173 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 75173 reports a median household income of $100,373, 7% below the $107,945 county median, and 47% above the $68,103 typical TX ZIP. Owner-occupied homes are valued at a median of $322,000, 24% below the county figure and 65% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,396 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Texas charges 6.25% statewide, and local governments overlapping 75173 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 75173 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.
