ZIP 70392 in context

How this area compares with national benchmarks.

ZIP 70392 is a mid-size town in St. Mary Parish, Louisiana, with 8,158 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #170 of 539 ranked by population — larger than 68% of them. The median age here is 37.1 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 70392 earn a median of $49,538 a year, 36.9% 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 21.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 70392 is valued at $141,600, 53.3% below the national figure, while median gross rent runs $760 a month, 45.9% below the national figure, or roughly $9,120 across a full year. A household on the local median income would put about 18.4% 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 2.9×, 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.

Reading ZIP 70392 in context

How 70392 sits inside St. Mary Parish and Louisiana.

ZIP 70392 is tabulated inside St. Mary Parish, Louisiana, one of 7 ZIP areas the Census publishes for that county and 539 across Louisiana. 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 70392 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 70392 reports a median household income of $49,538, 6% below the $52,600 county median, and 9% below the $54,720 typical LA ZIP. Owner-occupied homes are valued at a median of $141,600, 11% above the county figure and 8% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $760 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Louisiana charges 5% statewide, and local governments overlapping 70392 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 70392 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.
