>Comoros
People
The Comorians inhabiting Grande Comore, Anjouan, and Moheli (86% of the population) share African-Arab origins. Islam is the dominant religion, and Koranic schools for children reinforce its influence. Although Arab culture is firmly established throughout the archipelago, a substantial minority of the citizens of Mayotte (the Mahorais) are Catholic and have been strongly influenced by French culture.
The most common language is Shikomoro, a Swahili dialect. French and Malagasy are also spoken. About 48% of the population is literate.
