Some scholars broaden the definition to include other German killing policies during the war, including the mistreatment of Soviet POWs, crimes against ethnic Poles, euthanasia of mentally and physically disabled Germans, persecution of Jehovah's Witnesses, the killing of Romani, and other crimes committed against ethnic, sexual, and political minorities.[315] 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.[316] 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.[317][318]
