Some scholars broaden the definition of the Holocaust by including other German killing policies which were carried out during the war, including the mistreatment of Soviet POWs, crimes against ethnic Poles, mass murder of mentally and physically disabled Germans (which the Nazi authorities framed as "euthanasia"), persecution of Jehovah's Witnesses, the killing of Romani, and other crimes committed against ethnic, sexual, and political minorities. Using this definition, the total number of Holocaust victims is 11 million people. Donald Niewyk suggests that the broadest definition, including Soviet deaths due to war-related famine and disease, would produce a death toll of 17 million. Overall, about 5.7 million (78 percent) of the 7.3 million Jews in occupied Europe perished. This was in contrast to the five to 11 million (1.4 percent to 3.0 percent) of the 360 million non-Jews in German-dominated Europe. The United States Holocaust Memorial Museum has the number of people murdered during the Holocaust era at 17 million.
