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.
