 Many rural and urban women also transform some foodcrops into alcoholic drinks such as sorghum beer or hard liquor and derive considerable income from the sale of these drinks.Much of the income derived from the sale of foods and alcohol is not "on the books" and thus is not considered in calculating per capita income, which is one reason why official figures for per capita income are not accurate in the case of the CAR.The per capita income of the CAR is often listed as being around $400 a year, said to be one of the lowest in the world, but this figure is based mostly on reported sales of exports and largely ignores the more important but unregistered sale of foods, locally produced alcohol, diamonds, ivory, bushmeat, and traditional medicines, for example.
