More and more young American adults are living with their parents.

According to a recent report published by the Pew Research Center, the number of individuals between the ages of 25 to 34 living with their parents has jumped from 15.8 percent in the year 2000 to 21.6 percent in 2010.

In 1980, the rate for the same aged group stood at 11 percent but has been steadily climbing up until the present.

What causes these individuals (also popularly called "boomerang generation") to go back to live with mom and dad?

Although there may be several reasons, one for certain is the economy.

The report found that 61 percent of the people (ages 25 to 34) surveyed said that they know of friends or family that went back to live with their parents due to their 'economic conditions'.

29 percent of parents who have had their children move back with them have said that the economy was the main reason.

Parents normally have certain expectations for their children when they become adults. When these expectations are not met, friction in the relationship may arise.

However when asked how living with their parents has affected their relationship, 24 percent of young adults responded that the effect was positive while 25 percent said that it was negative. Some 48 percent said there was no difference in their relationship with their parents.

Many of these young adults also responded that they have positively helped their parents by contributing with the rent and other household expenses. 48 percent reported to have paying rent and 89 percent reported to have contributed with other expenses.

The survey was conducted on 2,048 adults from around the U.S. from Dec. 6-19, 2011.
