Data from the U.S. Census Bureau also shows that five New Jersey counties — Hunterdon, Somerset, Morris, Bergen, and Monmouth — have some of the largest concentrations of wealth in the United States, as defined by the percentage of households with an income of $200,000 or more. Four of five New Jersey counties also are among the ranks of those with the highest median household income.
Surprisingly, those two measures of wealth do not always overlap, at least not in New Jersey.
For instance, Sussex County made it into the ranks of the 25 wealthiest, at number 24, when measured by median household income. But it ranks 54th in the percentage of wealthy households.
Then again, Hunterdon and Somerset counties rank in the top 10 in both measures. With a median household income of just under $100,000, Hunterdon was the fourth-wealthiest county in the nation in 2011. The top three are all Virginia suburbs of Washington, D.C.: Loudon, Fairfax and Arlington counties. Those counties also were the three with the largest proportion of households having $200,000 or more in annual income. Hunterdon, where 16.5 percent of nearly 47,000 households were that wealthy, ranked fifth. Read the rest of this article at NJ Spotlight.
