Jefferson ZIP codes — Jefferson County, New York

Jefferson County is a mid-size city in New York, with 116,130 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 33.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Jefferson County earn a median of $64,978 a year, 17.3% 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 13.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Jefferson County is valued at $181,000, 40.3% below the national figure, while median gross rent runs $1,214 a month, 13.7% below the national figure, or roughly $14,568 across a full year. A household on the local median income would put about 22.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.
