One third of Americans believe only two million Jews were murdered during the Holocaust and 66% of millennials have never heard of Auschwitz, according to a comprehensive national survey of Holocaust awareness and knowledge among adults in the United States.

The survey was released by the Claims Conference, founded to deal with restitution for Holocaust survivors.

Over 45% of those asked could not name any of the 40 ghettos or concentration camps present in Europe during the Second World War. That number increased among people born in the 80’s and 90’s of the 20th century.

The study reveals 68% of Americans believe there is antisemitism in the US and 37% say neo-Nazis exist in large numbers. Seven out of ten say fewer people care about the Holocaust than in the past. A majority (58%) believe a similar event could take place again.

However not all results were negative. Nine out of ten surveyed (93%) believed all students should learn about the Holocaust in school and eight out of ten said it is important to keep teaching about the Holocaust so it does not happen again.
