Erma CDP, NJ in context

How this area compares with national benchmarks.

Erma CDP is a small town in New Jersey, with 2,039 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #454 of 700 ranked by population — larger than 35% of them. The median age here is 37.8 years against 39.1 nationally, a slightly younger 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 Erma CDP earn a median of $93,674 a year, 19.3% above the national figure of $78,538 and 12% below the $106,926 median for the 543 New Jersey cities we cover. 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 7.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Erma CDP is valued at $378,000, 24.6% above the national figure and 8% below the $412,500 peer median, while median gross rent runs $1,576 a month, 12.1% above the national figure, or roughly $18,912 across a full year. A household on the local median income would put about 20.2% 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 4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 73% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
