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
Eventually the Lithuanian speakers came to be known as Samogitians (see also Samogitian nobility), after the province in which they were the dominant majority. Another estimate for the combined population at the beginning of the 16th century gives 7.5 million, roughly split evenly, due to much larger territory of the Grand Duchy (with about 10-15 people per square km in Poland and 3-5 people per square km in the Grand Duchy, and even less in the south-east Cossack borderlands). By 1500, about 15% of Poland's population lived in urban centers (settlements with over 500 people).
