http://news.yahoo.com/half-people-surveyed-adl-dont-know-holocaust-201510025.htmlOnly 54 percent of the people surveyed by the Anti-Defamation League (ADL) in a massive, global poll have ever heard of the Holocaust. Even more disturbing, 32 percent of these believe the event to have been greatly exaggerated or a myth.
However, of the 32% doubters, seven eighths believe it has been exaggerated and only one eighth believe it is a myth (page 39).

There may be a problem with rounding. The ADL report seems to be inconsistent, as it says 35% of people have never heard of the holocaust (page 7), but 54% of respondents have heard of the holocaust (page 11), which leaves 11% unaccounted for. Only 33% have both heard of the holocaust and believe it has been accurately described by history (page 11).
In the Americas, of the 77% who have heard of the holocaust, 21% think it was a myth or an exaggeration (page 14).
In West Europe, of the 94% who have heard of the holocaust, 11% think it was a myth or exaggeration (page 15).
The same figures for:
Eastern Europe: 84%/24%
Sub-Saharan Africa: 24%/44%
Middle East: 38%/63%
Oceania (i.e. mostly Australia): 93%/8%.
English-speaking countries are more sympathetic to the Jews generally than other nations.
