For many people, a trip to see grandma constitutes a walk down the hallway.
Citing data from the Pew Research Center, CityLab notes that 60.6 million Americans live in multigenerational households, which is 19 percent of the total population. The rate is almost as high as it was in 1950, when 21 percent of the population lived with parents. The lowest rate was 1980, at 12 percent.
Two reasons for the increase include economic woes for younger adults (like student loans and lack of jobs), and the diversification of the U.S. population. Immigrants, particularly Asian and Hispanic ethnicities, prefer multigenerational living.
