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.
World War II casualties of Poland
In the aftermath of the September 1939 German and Soviet invasion of Poland, the territory of Poland was divided between Nazi Germany and the Soviet Union (USSR). The Soviet occupied territories of Poland, with total population of 13.0 million, was subjected to a reign of terror. According to research published in 2009 by the Institute of National Remembrance about 1.0 million Polish citizens from all ethnic groups were arrested, conscripted or deported by the Soviet occupiers from 1939 to 1941; including about 200,000 Polish military personnel held as prisoners of war; 100,000 Polish citizens were arrested and imprisoned by the Soviets, including civic officials, military personnel and other "enemies of the people" like the clergy and Polish educators; 475,000 Poles who were considered "enemies of the people" were deported to remote regions of the USSR; 76,000 Polish citizens were conscripted into the Soviet Armed forces and 200,000 were conscripted as forced laborers in the interior of the Soviet Union. When the Soviet forces returned to Poland in 1944-1945 there was a new wave of repression of Polish citizens from all ethnic groups including 188,000 deported, 50,000 conscripted as forced labor and 50,000 arrested.
