 The per capita income of the Republic is often listed as being approximately $400 a year, one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the unregistered sale of foods, locally produced alcoholic beverages, diamonds, ivory, bushmeat, and traditional medicine.The currency of Central African Republic is the CFA franc, which is accepted across the former countries of French West Africa and trades at a fixed rate to the euro.Diamonds constitute the country's most important export, accounting for 40–55% of export revenues, but it is estimated that between 30% and 50% of those produced each year leave the country clandestinely.
