What are the names of the four largest ethnic groups in Carabane?  Answer the above question based on the context below:  In 2003, the village of Carabane's official population count stood at 396 people and 55 households, but it fluctuates with the seasons and sometimes reaches some 1,750 people, according to local sources. Most of the population is Jola. The Jola are very distinct from other major ethnic groups in Senegal by their language, egalitarian society, freedom from political hierarchy, and lack of slavery. Their traditions have persevered because of their independent spirit as well as their geographical isolation. This ethnic group accounts for 80 to 90% of the residents of Basse Casamance, but only 6 to 8% of the total population of Senegal. They are the largest ethnic group in Carabane, followed by Wolofs, Lebous, and Serers (including Niominka fishermen). Manjacks also live on the island, some of whom came from Saint-Louis and Gorée at the time of the first colonization. Two communities from neighbouring countries, one from Guinea (the Susu people) and the other from Guinea-Bissau, have settled on the other side of the island at a distance from the village. There are also seasonal workers who come to fish: Ghanaians, Guineans, and Gambians.The indigenous population was originally animist, but while the fetishes and sacred groves dedicated to initiation rites such as boukout survive as cultural icons of Casamance, the monotheistic belief systems of Catholicism and Islam have become the most widely held in Carabane. The 1988 census reported that Muslims account for 94% of the population of Senegal, but only 26.5% of the population of Oussouye Department, where Carabane is located. Still, this department is largely rural, while Carabane has historically supported great ethnic diversity. Islam has not been practiced by Wolof and Serer fishermen since the 19th century, but the colonial administration brought with it many translators, guides, and secretaries from Dakar, many of whom were Muslim.
