You know the town. Every county has one.

It’s got the big houses, the nice schools, wide green lawns and, now, a coveted spot on this list.

A couple of years have passed since the last time NJ Advance Media took a look at the richest town in each county, and a lot has changed.

One town stayed on top despite its slight decline in median household income. (The median is the point at which half of the incomes are higher and half are lower. It helps account for extreme high or low incomes that would skew an average.)

That one town’s decline should hardly be cause for alarm. Sparta Township in Sussex County saw its median income fall from $131,150 to $130,288, a decrease of less than a thousand bucks, or 0.7%.

Morris County’s Chatham Township is the biggest gainer of those on the list. It has seen its median income rise from $156,607 in 2016 to $182,619 as of 2018 — a 16.6% leap. That was just enough to overtake Mendham Township for the county’s top slot by a mere $600.

Just one town here has a median income lower than the figure for the state as a whole. Cumberland County’s Hopewell Township sits at $78,893, just shy of the $79,363 seen on a statewide level. Among the 50 states, that places New Jersey second behind only Maryland and 28% higher than the national median income of $61,937.
