Nearly one in three millennials lives in their parents' home.
The US Census Bureau recently released a study on how young adulthood has changed between the 1970s and today. One of the main topics covered in the study was living situations.
In 1975, a 57% majority of young adults aged 18-34 lived with a spouse, while just 26% of adults lived in their parents' home. In 2016, only 27% of young adults lived with a spouse, while the proportion of 18-34 year olds living with their parents went up to 31%, becoming the most common living situation.
The report also noted that cohabitating with an unmarried partner has become much more common over the last few decades. In 1975, only around 1% of 18-34 year olds lived with an unmarried partner, while 12% of young adults were cohabitating in 2016.
Millennials haven't given up on the traditional milestones of adulthood; they've just delayed them. For example, the authors of the report wrote on the topic of marriage, "In 1995, women had a 59 percent chance of marrying by the age of 25. As of 2010, they had a 44 percent chance, a decline of 15 percentage points in just 15 years. Nonetheless, their chances of marrying by the age of 40 barely budged across the same period, from an 86 percent chance to an 84 percent chance."
Rates of living with parents vary across the country, ranging from just 14.1% in North Dakota to 46.9% in New Jersey. In general, living at home was more common in the South and the Northeast, while states in the middle of the country saw lower rates.
Here's the proportion of adults aged 18-34 who live in their parents' homes in each state:
