ABUJA (Reuters) - Nigeria has overtaken South Africa as Africa's largest economy after a rebasing calculation nearly doubled its gross domestic product, data from the statistics office showed on Sunday.
GDP for 2013 in Africa's top oil producer totalled 80.3 trillion naira, or $509.9 billion (307.4 billion pounds), the Nigeria Bureau of Statistics said, an increase from the 42.3 trillion estimated before the rebasing.
