Housing researchers generally treat about 3× income as manageable and 5× or more as severely stretched. Coverage is 21 of 21 tracked counties in New Jersey; income figures come from the Census Bureau's American Community Survey and home values from Zillow.
Violent crime rates below are a population-weighted average of each county's reporting cities from the FBI's Uniform Crime Reporting Program, covering 21 of 21 tracked counties in New Jersey. Counties with no FBI-reporting city aren't shown.
Cape May County has the highest median home value in New Jersey at $804,637. This is often searched as the "richest" or "wealthiest" county in New Jersey — though it's worth being precise about what's being measured here: median home value reflects property prices, not household income or net worth. The two usually correlate, but a county can have expensive homes without having the highest-earning residents, particularly in areas with a lot of vacation or second homes.
Hunterdon County has the highest median household income in New Jersey at $141,715. If what you're really after is the "richest" or "wealthiest" county in New Jersey, this is the closer answer — income measures what households actually earn each year, while home values measure what property costs. Neither is quite the same as wealth, which would also account for savings, investments and property people already own outright.
Cumberland County has the lowest median home value of the 21 New Jersey counties tracked here, at $279,971. Keep in mind that low home prices often reflect limited local job markets, distance from major metro areas, or shrinking population — affordability alone doesn't tell you whether somewhere is a good fit.
The typical (median) county in New Jersey has a home value of $592,229, against $236,981 for the median U.S. county — roughly 149.9% higher. Figures come from Zillow's Home Value Index and are refreshed daily on this site.
