Mastic, NY population, income and ZIP codes

Mastic CDP is a mid-size town in New York, with 15,031 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #133 of 1,292 ranked by population — larger than 89% of them. The median age here is 31.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Mastic CDP earn a median of $106,491 a year, 35.6% above the national figure of $78,538 and 16% above the $91,806 median for the 847 New York cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mastic CDP is valued at $370,500, 22.1% above the national figure and 17% above the $315,800 peer median, while median gross rent runs $2,055 a month, 46.2% above the national figure, or roughly $24,660 across a full year. A household on the local median income would put about 23.2% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 81.9% 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.

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.
