New Jersey ZIP Code Demographics
New Jersey is home to an estimated 9,343,809 people across 3,507,701 households. This page summarizes the state and profiles its 1 largest ZIP Code Tabulation Areas (ZCTAs) in depth.
Statewide, the median household income in New Jersey is $103,556 — 28.3% higher than the national median of $80,734 — and per-capita income is $54,253 versus $44,673 nationally. The median age is 40.1 years (national: 38.9), and 43.6% of adults age 25 and over hold a bachelor's degree or higher (national: 35.7%). Housing runs to a median home value of $454,400 and a median gross rent of $1,720, against national figures of $332,700 and $1,413.
Those state averages hide wide internal variation, which is exactly why this site works at ZIP level. In New Jersey, the profiled ZCTAs below range from 139,149 to 139,149 residents, and their median household incomes run from $64,959 to $64,959. A state figure is a useful benchmark; the ZIP-level profile is where the local story actually is. Each profile compares its ZCTA with these same state and national benchmarks so the contrast is explicit rather than implied.
The Largest Profiled ZIP Codes in New Jersey
| # | ZIP (ZCTA) | Main county | Population | Median HH income | |
|---|---|---|---|---|---|
| 1 | ZIP 08701 | Ocean County | 139,149 | $64,959 |
Rankings use total population from the American Community Survey (ACS) 2020–2024 5-year estimates. A ZCTA is the Census Bureau's statistical approximation of a ZIP Code, built from census blocks; it is not an exact USPS delivery boundary. ZCTAs are assigned to the state containing the largest share of their land area in the Census Bureau's ZCTA-to-county relationship file, so a ZCTA near a state line appears under its main state even though a small part may cross into a neighbor.

Because these are five-year averages for 2020–2024, they smooth the pandemic-era swing and describe the period as a whole.
To use this page well, start with the table: open the profile for any ZIP you care about, note its median income, home value and degree share, then come back here to see whether it sits above or below the state pattern. ZIP areas that beat the state on income but trail it on home value are often renter-heavy or newly built; areas with the reverse pattern are often older, owner-heavy communities. The profiles explain their own numbers in those terms, with the full demographic table on every page.
