Due to the territorial shift imposed from the outside, the number of Holocaust survivors from Poland remains the subject of deliberation. According to official statistics, the number of Jews in the country changed dramatically in a very short time. In January 1946, the Central Committee of Polish Jews (CKŻP) registered the first wave of some 86,000 survivors from the vicinity. By the end of that summer, the number had risen to about 205,000–210,000 (with 240,000 registrations and over 30,000 duplicates). The survivors included 180,000 Jews who arrived from the Soviet-controlled territories as a result repatriation agreements. Another 30,000 Jews returned to Poland from the USSR after the Stalinist repressions ended a decade later.
