The American middle class keeps shrinking.
"The share of American adults in middle-income households also decreased, from 55% in 2000 to 51% in 2014," Pew Research Center reports. "At the same time, the share of adults in the upper-income tier increased from 17% to 20%."
Although income is just one part of class, it's a crucial element and the one that's easy to measure and track.
So just how much do you need to make to qualify as middle class these days?
