Millennials came of age during a tough economic time: Student debt has reached an all-time high, and the job market is more competitive than ever. As a result, young people today aren't earning as much money as their parents did when they were young. The median annual income for employed millennials was taken from Minnesota Population Center's 2014 American Community Survey and Pew Research Center's definition of millennials: Americans born between 1981-1997. The medians ranged from a low of $18,000 per year in Montana to a high of $43,000 in the District of Columbia.
