A number of Chicago’s suburbs are among the 100 richest places in the U.S., a Bloomberg analysis of 2015 census data has revealed.
Winnetka, Glencoe and Lake Forest were the highest placed towns in the Chicago area, in 10th, 12th and 31st place respectively.
The study used 2015 average household income to determine the country’s wealthiest areas with a population greater than 2,000. The list was dominated by towns near New York City and California’s Silicon Valley, with Atherton, CA taking the top spot with an average income of $444,374.
Winnetka made the top 10 with an average of $311,902. For comparison, Illinois’s lowest entrant, 99th-placed Western Springs, averaged $192,936.
Unsurprisingly, the majority of the Chicago towns that featured are on the North Shore, though neighboring Hinsdale, Oak Brook and Western Springs to the southwest of the city also made the top 100. Of the 11 towns included, seven are in Cook County and four in Lake County.
All but one of the state’s towns’ average had risen from the same figure in 2014.
