Number of registered prisoners at Auschwitz 1941-1945 by ethnic origin

Of the 1.3 million people deported to Auschwitz during the Holocaust, between 1941 and 1945, roughly 400,000 were made prisoner and used for forced labor, while most of the remaining 900,000 were killed on arrival. Jews made up the largest ethnic group within the registered prison population, but this was much lower than their share of total arrivals or deaths at Auschwitz. In contrast, almost all of the (non-Jewish) Poles, Roma, or Soviet POWs who arrived at the camp were registered as laborers, yet most of these still died through a variety of other factors; such as exhaustion, starvation, disease, and murder.
