“Most U.S. adults know what the Holocaust was and approximately when it happened, but fewer than half can correctly answer multiple-choice questions about the number of Jews who were murdered or the way Adolf Hitler came to power, according to a new Pew Research Center survey. When asked to describe in their own words what the Holocaust was, more than eight-in-ten Americans mention the attempted annihilation of the Jewish people or other related topics, such as concentration or death camps, Hitler, or the Nazis. Seven-in-ten know that the Holocaust happened between 1930 and 1950. And close to two-thirds know that Nazi-created ghettos were parts of a city or town where Jews were forced to live. Fewer than half of Americans (43%), however, know that Adolf Hitler became chancellor of Germany through a democratic political process. And a similar share (45%) know that approximately 6 million Jews were killed in the Holocaust. Nearly three-in-ten Americans say they are not sure how many Jews died during the Holocaust, while one-in-ten overestimate the death toll, and 15% say that 3 million or fewer Jews were killed.

This raises an important question: Are those who underestimate the death toll simply uninformed, or are they Holocaust deniers – people with anti-Semitic views who “claim that the Holocaust was invented or exaggerated by Jews as part of a plot to advance Jewish interests”?
