ZIP 13646 in context

How this area compares with national benchmarks.

ZIP 13646 is a small town in St. Lawrence County, New York, with 2,373 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #975 of 1,824 ranked by population — larger than 46% of them. The median age here is 42.9 years against 39.1 nationally, a slightly older 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 13646 earn a median of $67,344 a year, 14.3% below the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 26% 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 13646 is valued at $133,000, 56.2% below the national figure, while median gross rent runs $803 a month, 42.9% below the national figure, or roughly $9,636 across a full year. A household on the local median income would put about 14.3% 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×, 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. 77.4% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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 13646 in context

How 13646 sits inside St. Lawrence County and New York.

ZIP 13646 is tabulated inside St. Lawrence County, New York, one of 45 ZIP areas the Census publishes for that county and 1,826 across New York. 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 13646 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 13646 reports a median household income of $67,344, 4% above the $64,583 county median, and 15% below the $79,429 typical NY ZIP. Owner-occupied homes are valued at a median of $133,000, 14% above the county figure and 43% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $803 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

New York charges 4% statewide, and local governments overlapping 13646 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 13646 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.
