Using only estimates based on the examination of the existing incomplete documentation, it can only be acknowledged that there were around 232,000 children aged under 15 and youth aged under 18 among the at least 1.3 million people deported to the German Nazi Auschwitz camp during the almost 5-year period of its operation. This number includes around 216,000 children and youth of Jewish origin, 11,000 Roma and Sinti, at least 3000 Polish, and over 1000 Belarusian, Russian, Ukrainian and other children and youth. The number of children registered as prisoners in the first years of operation of Auschwitz was low, but it steadily increased to reach a maximum in the latter half of 1944. Dr Wanda Witek Malicka from the Memorial’s Research Center talks about the fate of children in Auschwitz.
