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
Around 1490, the combined population of Poland and Lithuania, in a personal union (the Polish–Lithuanian union) since the Union of Krewo a century before, is estimated at about 8 million. An estimate for 1493 gives the combined population of Poland and Lithuania at 7.5 million, breaking them down by ethnicity at 3.25 million Poles, 3.75 million Ruthenians and 0.5 million Lithuanians. The Ruthenians composed most of the population of the Grand Duchy of Lithuania: this is the reason that the late GDL is often called a Slavic country, alongside Poland, Russia etc. In time, the adjective "Lithuanian" came to denote a Slav of the Grand Duchy.
