One of Robert Frost’s most beloved poems recounts the romance of taking the road less traveled. In recent years, newly divorced baby boomers have been heeding Frost’s words, traveling the relatively uncharted territory of single life after 50.

New research presented in April by sociologists Susan Brown and I-Fen Lin of Bowling Green State University revealed an unprecedented trend of Americans 50 and older splitting up.

According to the pair’s research, in 2009, people ages 50 and older were twice as likely to divorce as their counterparts in 1990.
