Poles
Polish people are the sixth largest national group in the European Union. Estimates vary depending on source, though available data suggest a total number of around 60 million people worldwide (with roughly 21 million living outside of Poland, many of whom are not of Polish ethnicity, but Polish nationals). There are almost 38 million Poles in Poland alone. There are also Polish minorities in the surrounding countries including (Germany), and indigenous minorities in the Czech Republic, Hungary, Slovakia, northern and eastern Lithuania, western Ukraine, and western Belarus. There are some smaller indigenous minorities in nearby countries such as Moldova. There is also a Polish minority in Russia which includes indigenous Poles as well as those forcibly deported during and after World War II; the total number of Poles in what was the former Soviet Union is estimated at up to 3 million.
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).
