Demographics of Poland
According to GUS, about 38,325,000 people live in Poland, however, the same report states that the number of residents living in the country all the time is approximately 37,200,000; with 1,125,000 people living abroad for 6 to 7 months or more. It means that the permanent population may be correspondingly smaller.
Polish diaspora
There are roughly 20 million people of Polish ancestry living outside Poland, making the Polish diaspora one of the largest in the world and one of the most widely dispersed. Reasons for the displacement include border shifts, forced expulsions, resettlement by voluntary and forced exiles as well as political and economic emigration. Major populations of Polish ancestry can be found in their native home region of Central Europe and in many other countries of Europe and also well in the Americas, Australasia and South Africa. There are also smaller Polish communities in most countries of Asia and Africa.
