New study says two-thirds of single Americans aren't sure they want to marry

A new article in USA Today highlights a recent study that found two-thirds of single adults in the United States now say they aren't sure they want to marry.

That's according to the second annual Singles in America study, which included data from 5,541 single adults across the country.

The people included in the study completed the survey online in December, and it was done as part of market research for dating website Match.com.

The study shows nearly 40% of singles 21 and older weren't sure they want to marry, and 27% say they definitely don't want to.

The single adults in the study also gave their opinions about relationships, and more than 20% said they don't have time or don't want to have a relationship, let alone get married.

Only 12.7% said they were actually looking for a relationship.

The article in USA Today also includes feedback from sociologist Michael Rosenfeld of Stanford University, who said he wasn't surprised by the findings, adding that marriage has gotten less and less frequent over the past 35 years.

The researchers also asked people in the survey what things they thought were deal breakers in terms of considering having a relationship with someone.

Having a messy or unclean appearance was cited most often, then laziness, no sense of humor, and living too far away.
