Within the past week, the Church has released a beta version of a new meetinghouse locator website at beta.lds.org/maps. For the first time since the Church has maintained an online meetinghouse locator, information regarding the spoken language of each congregation is provided. This information provides valuable information regarding the study of the growth of the Church among specific ethnolinguistic groups. For example, I was unaware that the Church in Cote d'Ivoire operates two congregations that conduct worship services in Baule, and one congregation each that conducts worship services in Bete and Gwere. Additionally, the website notes scores of congregations in Nigeria that conduct worship services in the Igbo language and dozens of congregations that conduct worship services other Nigerian languages such as Efik, Ibibio, and Yoruba.
I plan to update the LDS International Atlas to include information on the spoken language of each congregation. See below for an example of an updated map for the Nigeria Calabar Mission.
