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.
World War II casualties of Poland
Thaddeus Piotrowski is a Polish-American sociologist. He is a Professor of Sociology in the Social Science Division of the University of New Hampshire at Manchester. Piotrowski's assessment in 1998 of Polish war losses is that ""Jewish wartime losses in Poland are estimated to be in the 2.7-2.9 million range. (Many Polish Jews found refuge in the Soviet Union and other countries.) Ethnic Polish losses are currently estimated in the range of 2 million. (The number is probably higher if we add all those who died at the hands of the Ukrainian Nationalists.)""
