(Reuters) - Americans named President Obama and former Secretary of State Hillary Clinton as the World's most admired living man and woman in 2013 , according to a Gallup poll released on Monday .
Obama topped the annual list for the sixth consecutive year , a typical ranking for a sitting U.S. president , the polling organization said .
But the percentage of those surveyed who choose him as the most admired man fell to 16 percent this year , down from 30 percent in 2012 .
The president's job approval rating has dropped during a year marked by a botched healthcare rollout and stalled legislative initiatives at the start of his second term .
Clinton earned the top spot among women for the 12th consecutive year and 18th time overall , more than any other woman in the poll's history .
Fifteen percent of Americans surveyed gave the former first lady and U.S. senator the highest ranking , down from 21 percent who named her as the most admired woman last year , the poll showed .
Gallup said its data came from a poll of 1,031 adults between December 5 and 8 , and had a margin of error of plus or minus 4 percentage points .
Other men named to the list included former U.S. presidents George W. Bush , Bill Clinton and Jimmy carter ; Pope Francis and the Reverend Billy Graham ; actor and director Clint Eastwood ; Microsoft Crop co-founder and Philanthropist Bill Gates ; U.S. Senator Ted Cruz of Texas and former Republican presidential candidates Mitt Romney and Ron Paul .
The women who finished behind Hillary Clinton included talk show host Oprah Winfrey , first lady Michelle Obama , former Alaska Governor Sarah Palin , former Secretary of State Condoleezza Rice and actress Angelina Jolie .
Also on the list were Malala Yousafzai , the Pakistani teenager shot in the head by the Taliban for demanding education for girls ; German Chancellor Angela Merkel , and Britain's Queen Elizabeth and Duchess of Cambridge , Kate Middleton .
