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.
Kashubian language
The number of speakers of Kashubian varies widely from source to source, ranging from as low as 4,500 to the upper 366,000. In the 2011 census, over 108,000 people in Poland declared that they mainly use Kashubian at home, of these only 10 percent consider Kashubian to be their mother tongue, with the rest considering themselves to be native speakers of both Kashubian and Polish. The number of people who can speak at least some Kashubian is higher, around 366,000. All Kashubian speakers are also fluent in Polish. A number of schools in Poland use Kashubian as a teaching language. It is an official alternative language for local administration purposes in Gmina Sierakowice, Gmina Linia, Gmina Parchowo, Gmina Luzino and Gmina Żukowo in the Pomeranian Voivodeship. Most respondents say that Kashubian is used in informal speech among family members and friends. This is most likely because Polish is the official language and spoken in formal settings.
