Pennsylvania is reported to be among the top ten states whose population of millionaires has increased. Data from the Internal Revenue service says the Keystone State ranks ninth in the country for having the most residents whose adjusted gross income totals more than a million-dollars. Over 27-thousand residents achieved that between 2020 and 2021. The federal agency says the 47-percent increase has been fueled by stock market growth and rising salaries due to the post-pandemic labor shortage.
