It appears that along with an anemic economy, the United States has also set a record for the lowest percentage of married people - ever.

Just 51% of adult Americans are married, compared with 72% in 1960.

Pew said the number of adults co-habitating, single-person households and single parents had meanwhile increased in recent decades.

And, it appears that the number of married people in the United States may have not have troughed yet.

Pew, a nonpartisan think tank and polling organisation, found the percentage of those Americans who have been married at least once had declined as well - 72% in 2010, from 85% in 1960.

If the trend persists, in a few years less than half of Americans will be married, Pew said.
