The Lithuanian minority in Poland is composed of 5,639 people according to the Polish census of 2002, with most of them (5,097) living in the Podlaskie Voivodeship (Suwałki Region), particularly in Gmina Puńsk where they form a majority (74.4% of population). According to the Lithuanian embassy there are about 15,000 people of Lithuanian ancestry in Poland. 8,000 people declared Lithuanian identity in the Polish census of 2011 (including 5,000 who declared it as their only nationality, and 3,000 who declared it as the second one, after the Polish nationality).
There are Lithuanian publications (over 80 books have been published, and there are several magazines). Lithuanian organizations are involved in organizing cultural life of the minority (with libraries, choirs, theatres, etc.). There are also Lithuanian-language programmes on local Radio Białystok and Telewizja Białystok.
The minority has also Lithuanian-exclusive schools in Puńsk, both on primary and secondary level, schools with Lithuanian-language as a teaching language in Sejny, and schools with Lithuanian as a foreign language in the wider region are common. There are 17 Lithuanian schools, attended by over 700 students.
However local Lithuanian World Community representatives claim there are problems with Lithuanian culture preservation in Sejny region. They argue that Lithuanian heritage is ignored, as currently in Sejny there is not even one street name that would signify presence of prominent Lithuanians. They also note that for more than two years there is no accommodation regarding cemetery where Lithuanian soldiers are buried. Another recent issue is the underfunding of the two Lithuanian gymnasiums in Sejny, which receives only 75% of promised funding.
