Nigeria surpasses SA as Africa's biggest economy
Gross Domestic Product (GDP) for 2013 in Africa's top oil producer totaled 80.3-trillion naira or $509.9-billion, the Nigeria Bureau of Statistics said – an increase from the 42.3-trillion estimated before the rebasing.
The new figure shrank Nigeria's debt-to-GDP ratio to 11% for 2013, against 19% in 2012, statistics chief Yemi Kale told reporters in the capital of Abuja.
Most governments overhaul GDP calculations every few years to reflect changes in output and consumption, but Nigeria had not done so since 1990, so sectors such as e-commerce, mobile phones and its prolific "Nollywood" film industry had to be newly factored in to give a more accurate picture.
Growing attention from foreign investors was forcing Nigeria to more accurately calculate its statistics, including GDP, Kale said, adding that the base year would now be recalibrated every five years, in line with global norms.
Nigeria, Africa's most populous country with 170-million people, has been growing as a destination for foreign investors owing to the size of its consumer market and increasingly sophisticated capital markets.
But political risk as Nigeria approaches hotly contested elections in February next year remains a concern, as does a bloody insurgency waged by Islamist sect Boko Haram in the country's poor and underdeveloped northeast.
