Bilingual communes in Poland

The bilingual status of gminas (municipalities) in Poland is regulated by the Act of 6 January 2005 on National and Ethnic Minorities and on the Regional Languages, which permits certain gminas with significant linguistic minorities to introduce a second, auxiliary language to be used in official contexts alongside Polish. So far 44 gminas have done this:^[1]
