Single people who embrace their single lives are likely to experience more psychological growth and development than married people, according to a psychologist who presented at the American Psychological Association's 124th Annual Convention.

"The preoccupation with the perils of loneliness can obscure the profound benefits of solitude," said Dr. Bella DePaulo, PhD, a scientist at the University of California, Santa Barbara.

"It is time for a more accurate portrayal of single people and single life -- one that recognizes the real strengths and resilience of people who are single, and what makes their lives so meaningful."

There are more unmarried people than ever before in the United States. In 2014, there were 124.6 million unmarried Americans over age 16, meaning 50.2 percent of the nation's adult population identified as single, according to the government.

In contrast, only 37.4 percent of the population was unmarried in 1976.

Dr. DePaulo cited longitudinal research that shows single people value meaningful work more than married people. She also said another study showed single people are also more connected to parents, siblings, friends, neighbors and coworkers.

"When people marry, they become more insular," she noted.

Research on single people is lacking, claimed Dr. DePaulo. She searched for studies of participants who had never married and, of the 814 studies she found, most did not actually examine single people but used them as a comparison group to learn about married people and marriage in general.

She said the studies that did focus on single people revealed some stunning findings.

Research comparing people that stayed single with those that stayed married showed single people have a heightened sense of self-determination and they are more likely to experience "a sense of continued growth and development as a person," said Dr. DePaulo.

Another study of lifelong single people showed that self-sufficiency serves them well: The more self-sufficient they were, the less likely they were to experience negative emotions. For married people, the opposite was true, according to Dr. DePaulo.

Married people should be doing a lot better than single people in view of the number of laws that benefit them, said Dr. DePaulo, but in many ways, they aren't.

"People who marry get access to more than 1,000 federal benefits and protections, many of them financial," she said. "Considering all of the financial and cultural advantages people get just because they are married, it becomes even more striking that single people are doing as well as they are."

Despite the advantages of staying single, DePaulo doesn't claim one status is better than the other.

"More than ever before, Americans can pursue the ways of living that work best for them. There is no one blueprint for the good life," she said.

"What matters is not what everyone else is doing or what other people think we should be doing, but whether we can find the places, the spaces and the people that fit who we really are and allow us to live our best lives."
