Montenegro is a multiethnic state in which no ethnic group forms a majority. Major ethnic groups include Montenegrins (Црногорци/''Crnogorci'') and Serbs (Срби/''Srbi''); others are Bosniaks (''Bošnjaci''), Albanians (''Albanci – Shqiptarët'') and Croats (''Hrvati''). The number of "Montenegrins" and "Serbs" fluctuates widely from census to census due to changes in how people perceive, experience, or choose to express, their identity and ethnic affiliation.
