The divorce rate in the U.S. is falling, and it's all thanks to millennials. A new University of Maryland study found that divorce rates fell 18 percent between 2008 and 2016. It's because millennials, along with Generation X, are waiting longer to get married and making sure they're marrying the right person. It also helps that they're more financially stable. Meanwhile, baby boomers continue to get divorced and remarried over and over again, even into their 70s.
