* Bosnian, Croatian, Serbian, and Montenegrin are very similar languages. They are often considered to be dialects of a single language (Serbo-Croatian) or variations of a single language.
* There's no official census that specifically counts Bosnian speakers. Most official census data focuses on the broader category of Serbo-Croatian speakers.
* Bosnian is spoken in several countries. These include Bosnia and Herzegovina, Serbia, Montenegro, Croatia, and other countries with large diaspora communities.
However, we can estimate based on various sources:
* Bosnia and Herzegovina: The majority of the population speaks Bosnian, with estimates ranging from 2-3 million speakers.
* Other countries: Bosnian is spoken by significant minorities in Serbia, Montenegro, and Croatia. Estimates range from several hundred thousand to a few million in these countries.
* Diaspora: Bosnian is spoken by a large diaspora community, primarily in Western Europe and North America. Estimates range from hundreds of thousands to millions.
Based on these estimates, it's reasonable to say that there are likely between 5 and 10 million Bosnian speakers worldwide.
