Nigeria's National Bureau of Statistics published rebased gross domestic product figures using 2010 as the base year, raising the measured size of the economy to about $510bn and placing it ahead of South Africa.
The revision captured sectors that had grown substantially since the previous 1990 base year, including telecommunications, banking, entertainment and retail. Nollywood and mobile services in particular had barely registered in the older accounts.
Economists cautioned that the exercise changed the measurement rather than living standards. Per capita income remained low and the revision also reduced Nigeria's tax-to-GDP ratio, underlining a narrow revenue base.
