The quick read

Unemployment is 4.6% and median household income $127,339, putting employment conditions in the middle range of published ZIP profiles.

Housing is more affordable relative to local incomes than in most published city profiles: rent takes 16% of median household income and the median home is 3.0 times it.

Physical-risk exposure is above the national median, driven mainly by inland flooding, hurricane and strong wind.

38.5% of students here are eligible for free or reduced-price lunch. That describes the circumstances families arrive with rather than how the schools perform, which is why AreaProfile shows it and does not score it.

Public schools only, from the NCES Common Core of Data. Schools are placed by ZIP code, so this is which schools are in this place rather than which one a particular address is zoned for — district boundaries do not follow municipal ones, and enrollment zones change. Fully virtual schools are excluded: they enroll students from across the state while reporting one administrative address, and counting them here would describe a school population this place does not have. The assessment covers grades 3 through 8, so a high school shows no proficiency figure — a dash in those columns means the test was not given at that school, not that it performed badly. Proficiency is measured against New Jersey’s own standard, so it compares cleanly within the state and only broadly against other states; AreaProfile therefore ranks it within state. The directory is current, while the proficiency figures are from the last school year with national coverage before the pandemic interrupted testing.

Housing & affordability

How it’s calculated →

Prices for everything a household buys run about 2% above the national average, on the Bureau of Economic Analysis index. Housing drives most of that difference.

Median rent of $1,700 takes 16% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 3.0 times median household income here, above the historic benchmark of about three times income.

Cost of living
102.4

Prices here run about 2% above the national average. The spread between places is driven mostly by housing — goods vary far less — and this excludes taxes.

Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.

Weather & climate

6 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 86°F and January a low of 24°F.

Normal annual precipitation is 45.6 inches, including 26.6 inches of snow.

Air quality measures a median index of 43, in the Good band, and about 5 days a year pass 100, the threshold at which the air is unhealthy for sensitive groups.

A comfortable median and a bad tail are different problems. Wildfire smoke and summer ozone show up in the worst tenth of days, not in the middle of the year.

Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today. Air quality is measured rather than modelled, by EPA monitors, and published by county only where a monitor sits — roughly half the counties AreaProfile publishes have one, and the rest show nothing rather than an estimate. Air masses are regional, so a county reading describes the air over a place reasonably well, but it is still the county reading.

Physical risk

36 / 100
Physical resilience

The hazards accounting for most of this area's expected annual loss are inland flooding, hurricane and strong wind.

Strong windHigh
Inland floodingElevated
Ice stormModerate
HurricaneElevated
EarthquakeElevated
DroughtModerate

Low or minimal exposure: winter weather, heat wave, lightning, cold wave, tornado, wildfire, coastal flooding, landslide, hail.

Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA publishes at county level. ZIP values are the land-area-weighted mean of the counties the ZIP Code Tabulation Area intersects. Expected annual loss is not allocated below county level. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.

These are deaths, not offences — they say nothing about burglary, theft or assault.

Mercer County records 4.5 homicide deaths per 100,000 residents a year, near the middle of counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 5.5 per 100,000 — more than the homicide rate, because nationally most firearm deaths are suicides.

Drug overdose deaths run at 23.8 per 100,000 residents in Mercer County.

Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides. The two columns overlap and should not be added.

Age-adjusted rates from provisional death certificate records, published by the CDC for Mercer County as a whole — these rates are not published below county level. A county can hold both a dense city centre and a suburb whose experience of it is nothing alike, so this describes the county around 08690 rather than 08690 itself. That is why AreaProfile shows these figures and does not put them in the Area Score. Where fewer than ten deaths were recorded the count is suppressed at source, and a rate built on single figures moves sharply between releases. What this measure has that reported crime does not: a death certificate is filed whether or not the local police agency submitted a return that year, so the figures stay comparable between places and over time.

What this profile does not cover

Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.

Reported crime
Offences reported to police are published by department rather than by town, and only where a department reported every month of the year. No municipal department reports for this place — many smaller communities are policed by the county — so there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
Taxes
Taxes are not published: no source covers them nationally with a method open enough to check. Cost of living now is — the index above is the Bureau of Economic Analysis price parity for this area — but it is a price level for all consumption rather than a budget for a household, its spread is driven mostly by housing, and it excludes taxes. Housing affordability is computed separately from rent, price and income, because that answers a narrower and more actionable question. Nothing here is individualised tax advice.
Anything about a specific address
Every figure describes an area, not a street or a house. School attendance zones, insurance pricing and the character of a neighbourhood all vary within the places measured here.
