Demographics of Poland
According to the 2011 census by the Polish Central Statistical Office (GUS), at the end of 2011 Poland had a population of 38,538,447, which translates into an average population density of 123 people/km (urban 1105 per 1 km², rural 50 per 1 km²). 61.5% of the Polish population lives in urban areas, a number which is slowly diminishing. Poland is the 33rd most populous country in the world (9th in Europe, with 5.4% of the European population). Total population of Poland is almost stagnant (population growth was 0.08%). Average life expectancy was 70.5 for men and 78.9 for women. In 2009, it was expected to be 73.1 for men and 79.5 for women. Population distribution is uneven. Ethnically, Poland is a very homogeneous country, with 96.7% of population being Polish.
Demographic history of Poland
Before World War II, a third of Poland's population was composed of ethnic minorities. After the war, however, Poland's minorities were mostly gone, due to the 1945 revision of borders, and the Holocaust. Under the National Repatriation Office ("Państwowy Urząd Repatriacyjny"), millions of Poles were forced to leave their homes in the eastern Kresy region and settle in the western former German territories. At the same time approximately 5 million remaining Germans (about 8 million had already fled or had been expelled and about 1 million had been killed in 1944-46) were similarly expelled from those territories into the Allied occupation zones. Ukrainian and Belarusian minorities found themselves now mostly within the borders of the Soviet Union; those who opposed this new policy (like the Ukrainian Insurgent Army in the Bieszczady Mountains region) were suppressed by the end of 1947 in the Operation Vistula.
