Four other sizable groups of people are referred to as "national minorities" ("nationale Minderheiten") because they have lived in their respective regions for centuries: Danes, Frisians, Roma and Sinti, and Sorbs. There is a Danish minority (about 50,000, according to government sources) in the northernmost state of Schleswig-Holstein. Eastern and Northern Frisians live at Schleswig-Holstein's western coast, and in the north-western part of Lower Saxony. They are part of a wider community (Frisia) stretching from Germany to the northern Netherlands. The Sorbs, a Slavic people with about 60,000 members (according to government sources), are in the Lusatia region of Saxony and Brandenburg. They are the last remnants of the Slavs that lived in central and eastern Germany since the 7th century to have kept their traditions and not been completely integrated into the wider German nation.
