A recent report from the U.S. Census about changes in living patterns among young adults from 1975 to 2016 has some interesting findings. It reports the delayed forming of families. In 1975, 57 percent of adults 18 to 34 were living with a spouse; that number dropped to 27 percent in 2016. Meanwhile, the percentage living with their parents climbed from 26 percent to 31 percent.
Part of this change might be because of increased college attendance and changes in sexual mores, but part of it might also be because of increased economic pressures. In 1975, only 25 percent of men between 25 and 34 were making under $30,000 a year (in 2015 dollars); by 2016, 41 percent of men were making less than that.
