Hunterdon County led the state with an average net worth of $159,394, finishing with the highest mark in the state, based on SmartAsset’s index of net worth, and the second-highest mark in the nation. It trailed only Sumter County in Florida, thanks to residents having more than three times the county’s average income of $51,353.



Sussex County was second-highest in the state. Its average net worth of $97,682 was a significant downstep from the No. 1 spot, but it fared well in the index due to more favorable net worth percentages of income and debt.



Of New Jersey’s 21 counties, five of them were in the national Top 20 for highest net worth: Hunterdon, Sussex (8th), Somerset (14th), Morris (18th) and Ocean (19th).



SmartAsset created an index for measuring net worth by comparing average income, average debt, net worth as percentage of income and net worth as percentage of debt.



Hudson, Essex and Passaic counties made up the bottom of the list.
