Approximately 90 % of Polish Jews perished ; most of those who survived did so by fleeing to the Soviet Union . 380,000 Polish Jews were estimated to have survived the war . According to an estimate of the Central Committee of Polish Jews , 50,000 Jews survived in Poland . Close to 300,000 Jews found themselves in Poland soon after the war . For a number of reasons , including antisemitic activities such as the Kielce pogrom of 1946 , Żydokomuna accusations , loss of families , communities and property , desire to emigrate to Palestine or to places in the West deemed more advantageous than post-war Poland , most of the surviving Jews left Poland in several stages after the war . The goal of Polish communist authorities was a state populated by ethnic Poles and the officials often informally facilitated departures of the Jews
