For a variety of reasons, young adults are more likely to live at home than ever. Among these reasons are: to finish school, to reduce spending, to save money after completing school, to begin repaying college debt, and to avoid certain household tasks.
According to the Pew Research Center, more young U.S. adults now live with their parents than before:
“In 2014, for the first time in more than 130 years, adults ages 18 to 34 were slightly more likely to be living in their parents’ home than they were to be living with a spouse or partner in their own household. This turn of events is fueled primarily by the dramatic drop in the share of young Americans who are choosing to settle down romantically before age 35.”
In industrialized countries other than the United States, how many young adults live with their parents? As Niall McCarthy reports for Statista:
“In many countries around the world, a huge proportion of young people still live at home with their parents. According to an OECD report, that trend is most pronounced in countries badly hit by the global financial crisis, particularly in Italy, Greece and Spain. 8 out of every 10 Italians aged between 15 and 29 still lived at home with their parents in 2014. In Scandinavia, youth living at home is a rarer phenomenon. In 2014, only 35 percent of young Swedish people still lived with their parents.”
