Guinea, officially the Republic of Guinea, is a west-coastal country in West Africa. Formerly known as French Guinea, the modern country is sometimes referred to as Guinea-Conakry to distinguish it from other countries with "Guinea" in the name and the eponymous region, such as Guinea-Bissau and Equatorial Guinea. Guinea has a population of 12.4 million and an area of 245,857 square kilometres (94,926 sq mi). The sovereign state of Guinea is a republic with a president who is directly elected by the people. The unicameral Guinean National Assembly is the legislative body of the country. The judicial branch is led by the Guinea Supreme Court. Guinea is a predominantly Islamic country, with Muslims representing 85 percent of the population. Guinea's people belong to twenty-four ethnic groups. French, the official language of Guinea, is the main language of communication but more than twenty-four indigenous languages are also spoken. Guinea's economy is largely dependent on agriculture and mineral production. It is the world's second largest producer of bauxite, and has rich deposits of diamonds and gold. The country was at the core of the 2014 Ebola outbreak. Human rights in Guinea remain a controversial issue.
