History of Poland (1945–1989)
"b1."Andrzej Leder gives the following figures, quoting Andrzej Paczkowski and Henryk Słabek. Of the 4.7 million people who populated the Recovered Territories in 1945–1950, 2.9 million came from central and south-eastern provinces of the new Polish territory and over 1.5 million from what had become the Soviet Union; smaller numbers of settlers arrived from France, Germany and other countries. From February 1946 to the end of 1948, 2.2 million Germans had to leave Poland (Paczkowski). 2.8 million Poles returned to Poland after the war from Germany and other parts of Western Europe (out of the total of 3.0–3.5 million war displaced who were present there) and many of them settled in the Recovered Territories.(Słabek).
