Ethnologue: Languages of the World is a web and print publication of SIL International (formerly known as the Summer Institute of Linguistics), a Christian linguistic service organization which studies lesser-known languages primarily to provide the speakers with Bibles in their native language.
For example, in Ethnologue, the speakers of Persian and Azerbaijani languages in Iran are estimated as 36% and 37%, respectively.
Sometimes the total numbers of speakers of languages in a country differ from the overall population figure: for example, for Croatia, Ethnologue gives a total population of 4,496,869 while, remarkably, the number of Croatian speakers in Croatia is reported to be 4,800,000.
