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.
Polish Americans
The U.S. Census asked Polish immigrants to specify Polish as their native language beginning in Chicago in 1900, allowing the government to enumerate them as an individual nationality when there was no Polish nation-state. No distinction is made in the American census between ethnically Polish Americans and descendants of non-ethnic Poles, such as Jews or Ukrainians, who were born in the territory of Poland and considered themselves Polish nationals. Therefore, some say, of the 10 million Polish Americans, only a certain portion are of Polish ethnic descent. On the other hand, many ethnic Poles when entering the US from 1795 to 1917, when Poland did not exist, did not identify themselves as ethnic Poles and instead identified themselves as either German, Austrian or Russian (this pertained to the nations occupying Poland from 1795 to 1917). Therefore, the actual number of Americans of at least partial Polish ancestry, could be well over 10 million. In the 2011 United States Census Bureau's Population Estimates, there are between 9,365,239 and 9,530,571 Americans of Polish descent, with over 500,000 being foreign-born.
