Young people aren't just rejecting marriage -- they're rejecting commitment altogether. A Gallup poll released Monday found that not only are fewer young people getting married, there are also fewer young people getting into serious relationships.

The number of young people living together in a relationship has stayed relatively stagnant, signifying that fewer people are living in a committed relationship. In 2004, 52 percent of young people 18-29 reported being single and not living with someone. In 2014, that number rose sharply to 64 percent.

It's not just those in the 18-29 age range. Those in their 30s are shying away from marriage too, although they are perhaps more likely to commit. 30-somethings are getting married at rates far lower than a decade ago -- about 56 percent compared with about 67 percent. But the percentage of those living together in a relationship nearly doubled, from 7 percent to 13 percent. Those in their 30s might not break the wedding rings out as often, but they are increasingly living an unmarried but committed lifestyle. Still, the overall trend holds -- slightly more people in the their 30s were single. Meanwhile, Gallup found the living arrangement of people over 40 remained relatively unchanged. The poll's results are based on Gallup's yearly aggregate data taken from 15,000 to 32,000 interviews with adults 18 and older. Results for national adults as a whole have a margin of error of 1 percentage point, while results for the specific "young people" age ranges have a margin of error of 3 percentage points.

Millennials continue to be reluctant to marry. A Pew poll in March 2014 found that fewer millennials -- ages 18-32 -- were getting married compared with past generations. Just 26 percent of the millennials polled were married. For the same age range, 32 percent of Gen Xers were married in 1997, 48 percent of baby boomers were married in 1980, and 65 percent of the silent generation was married in 1960.

Young people might not commit to relationships now, but it doesn't appear they want to keep things that way. Gallup found that people 18-34 wanted to get married as much as older adults. Pew found that nearly 70 percent of unmarried millennials hope one day to marry. At the very least, their parents perhaps hope they'll get out of the house. While young people may enjoy independence in relationships, about 14 percent of people ages 24-34 still lived under their parents' roof in 2013, according to Gallup.
