[42] In Bosnia and Herzegovina, religion is often linked to ethnicity, i.e. (with the exception of agnostics and atheists) most Bosniaks are Muslim, Serbs are Orthodox Christian, and Croats are Roman Catholic.
Bosnia's constitution does not specify any official languages;[44][45][46] however, academics Hilary Footitt and Michael Kelly note that the Dayton Agreement states that it is "done in Bosnian, Croatian, English and Serbian", and they describe this as the "de facto recognition of three official languages" at the state level.
[47] Michael Kelly and Catherine Baker argue: "The three official languages of today's Bosnian state...represent the symbolic assertion of national identity over the pragmatism of mutual intelligibility".
