Poles
Polish people are the sixth largest national group in the European Union. Estimates vary depending on source, though available data suggest a total number of around 60 million people worldwide (with roughly 21 million living outside of Poland, many of whom are not of Polish ethnicity, but Polish nationals). There are almost 38 million Poles in Poland alone. There are also Polish minorities in the surrounding countries including (Germany), and indigenous minorities in the Czech Republic, Hungary, Slovakia, northern and eastern Lithuania, western Ukraine, and western Belarus. There are some smaller indigenous minorities in nearby countries such as Moldova. There is also a Polish minority in Russia which includes indigenous Poles as well as those forcibly deported during and after World War II; the total number of Poles in what was the former Soviet Union is estimated at up to 3 million.
Polish People's Republic
The population of Jews in Poland, which formed the largest Jewish community in pre-war Europe at about 3.3 million people, was all but destroyed by 1945. Approximately 3 million Jews died of starvation in ghettos and labor camps, were slaughtered at the German Nazi extermination camps or by the Einsatzgruppen death squads. Between 40,000 and 100,000 Polish Jews survived the Holocaust in Poland, and another 50,000 to 170,000 were repatriated from the Soviet Union, and 20,000 to 40,000 from Germany and other countries. At its postwar peak, there were 180,000 to 240,000 Jews in Poland, settled mostly in Warsaw, Łódź, Kraków and Wrocław.
