Armonk CDP, NY in context
How this area compares with national benchmarks.
Armonk CDP is a small town in New York, with 4,382 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #388 of 1,292 ranked by population — larger than 70% of them. The median age here is 42.6 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 Armonk CDP earn a median of $245,500 a year, 212.6% above the national figure of $78,538 and 167% above the $91,806 median for the 847 New York cities we cover. 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 5.4% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Armonk CDP is valued at $1,029,300, 239.3% above the national figure and 226% above the $315,800 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 92.9% 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. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
The Census withheld gross rent for Armonk CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
