“There are economic activities that have no legal backing,” he said, citing prostitution.
“The practitioners earn income from them and sometimes live bigger than those in the formal sector. At the end of the day, the income earned impacts the formal economy,” Waniko said.
Nigeria last revised its GDP in 2010.
Waniko said a new calculation was necessary to reflect changing economic realities.
It will consider 2019 as the base year, he said, adding that new segments to be considered in the calculation include the digital economy, health and social insurance, pensions, modular refineries, mining and households employing labour.
“We expect that the size of the economy will be bigger,” he said.
“The tax-to-GDP ratio is something that people may want to see ... Debt to GDP ratio of 18.5% as of September 2019 could also reduce with the bigger size of the GDP, and then per-capita income will increase after the rebasing.”
He said the contribution of the crude oil sector to the economy had reduced, dropping from third place to fifth.
The real estate sector is now in third place after agriculture and trade.
