More than half of New Yorkers expect the Big Apple to be bruisedby another Sandy-sized storm within the next two decades, a SwissRe survey shows.

Natural disasters cost the global economy $160 billion lastyear, according to Swiss Re. Superstorm Sandy caused more than $28billion in insured losses when it struck the Northeast U.S. in lateOctober 2012.

Sixty-five percent of New Yorkers sustained some degree ofdamage during the “perfect storm” of October 2012, which was theregion's deadliest in 40 years and the second-costliest in U.S.history.

The findings were based on data from Swiss Re's risk perceptionstudy conducted in April and May 2013 by The Gallup Organisation,which polled nearly 22,000 individuals 15 years of age and aboveworldwide.

“We worked very closely with Mayor Bloomberg's administration inNew York to put together a report launched in June which looked atways to increase the city's resilience to climate change and severeweather events,” said Bill Donnell, head of Property & Casualtyin the Americas for Swiss Re, in a statement. “This survey,however, shows that people in the city still feel too vulnerableand it's important that we don't forget the lessons learned fromHurricane Sandy and continue to look for, and implement, ways toincrease resilience to major natural disasters.”

The survey canvasses regional ideas of risk in various globalcommunities, split by age group and risk source. Check out more ofSwiss Re's results on the poll's online portal.
