How did the top Garden State counties compare nationally? The wealthiest county in the nation is Teton in Wyoming, with a per capita investment of $212,319, median home value of $1.06 million, and per capita income of $220,645.

The counties rounding out the top 10 in the nation were New York; San Mateo, Calif.; Pitkin, Colo.; San Francisco; Nantucket, Mass.; Marin, Calif.; Summit, Utah, Santa Clara, Clara, Calif.; and Monroe, Fla. See the breakdown here.

According to the methodology, to identify the wealthiest counties, analysts calculated the investment index for each county by weighing the ordinary dividends, qualified dividends and net capital gains. Then they tallied calculated the median home value, and the per capita income for each county, and ranked them on all three metrics. Its sources were IRS SOI Tax Statistics, National Association of Realtors and BEA Data.

Also calculated was a wealth index based on the combination of the three metrics to see which areas of the U.S. are accumulating the most wealth.
