Twenty-six percent of all adults worldwide harbor anti-Semitic attitudes and nearly half have never heard of the Holocaust, the Anti-Defamation League said in what it described as an unprecedented and sobering global survey that assessed the level and intensity of hostility toward Jews

The highest concentration of anti-Semitic attitudes was found in the Middle East and North Africa, the survey showed, led by the West Bank and Gaza, where 93% of respondents held such views, followed by Iraq at 92%, Yemen at 88% and Algeria at 87%. The areas where anti-Semitic attitudes were least prevalent were Oceania, the Americas and Asia. In Laos, less than 1% of the population held such views, the lowest anywhere, the survey said. In Europe, the survey showed Greece to be the most anti-Semitic country, at 69%, and Sweden the least, at 4%. In the United States, the survey found 9% of respondents anti-Semitic. The most widely held stereotype, the survey showed, was an affirmative answer to this statement: “Jews are more loyal to Israel than to this country/the countries they live in.”
