Globally, about 15 percent of people believe the world will end during their lifetime, according to a new Reuters survey.
The Mayan calendar sets 2012 as the year of the apocalypse. About 10 percent of people worldwide believe that calculation to be true.
"Whether they think it will come to an end through the hands of God or a natural disaster or a political event, whatever the reason, 1 in 7 thinks the end of the world is coming," explained Keren Gottfried, research manager at Ipsos Public Affairs, the group that conducted the poll for Reuters.
About 1 in 10 respondents also said they were experiencing fear or anxiety about the possibility of the world ending in 2012.
Researchers found that those under age 35 or in a lower income or education bracket were more likely to believe the world will end soon.
The survey involved 16,262 people in more than 20 countries.
