( CNN ) -- One in four adults worldwide are `` deeply infected with anti-Semitic attitudes , '' the Anti-Defamation League announced , in releasing results of an unprecedented global survey . Nearly half have never heard of the Holocaust , and only a third believe historical descriptions are accurate , the survey found . Carried out by First International Resources and commissioned by the Anti-Defamation League , the survey included 53,100 adults in 102 countries representing 88 % of the world 's adult population . In native languages , it asked people whether certain traditionally anti-Semitic statements are probably true or false , including that Jews have too much power over international markets , global media , and the U.S. government ; that they `` do n't care about what happens to anyone but their own kind , '' and that `` Jews are responsible for most of the world 's wars . '' The survey then calculated how many believed that at least six of the 11 stereotypes were probably true . In the Middle East and North Africa , 74 % did . In Eastern Europe , one in three did , and in Western Europe and sub-Saharan Africa , nearly one in four believed most of the stereotypes . Overall , 26 % believed at least six of the stereotypes -- a figure representing an estimated 1.1 billion people . The most widely believed stereotype was that Jews are more loyal to Israel than to the countries in which they live . `` For the first time we have a real sense of how pervasive and persistent anti-Semitism is today around the world , '' ADL National Director Abraham Foxman said in a statement . `` The data from the Global 100 Index enables us to look beyond anti-Semitic incidents and rhetoric and quantify the prevalence of anti-Semitic attitudes across the globe . We can now identify hotspots , as well as countries and regions of the world where hatred of Jews is essentially nonexistent . '' In Laos , only 0.2 % of the adult population holds anti-Semitic views , the survey found . Also at the bottom of the list were the Philippines , Sweden and the Netherlands . In the United States , 9 % of respondents believed the majority of the stereotypes . The highest levels were found in the Palestinian territories at 93 % and Iraq at 92 % . Yemen , Algeria , Libya and Tunisia were next . In Asia , less than a quarter of respondents had heard of the Holocaust and believed historical accounts are accurate . In sub-Saharan Africa , that figured dropped to 12 % ; in the Middle East and North Africa , 8 % . Three quarters of the people surveyed said they 've never met a Jewish person . That figure includes most of the people who believe a majority of the anti-Semitic stereotypes are probably true . Former NYPD officer charged with hate crimes in anti-Semitic vandalism .
