The findings, based on a projection by the World Poverty Clock and compiled by Brookings Institute, show that more than 643 million people across the world live in extreme poverty, with Africans accounting for about two-thirds of the total number.
In Nigeria, as with other countries on the continent, that figure is projected to rise. "By the end of 2018 in Africa as a whole, there will probably be about 3.2 million more people living in extreme poverty than there are today," the researchers write.
Despite being the largest oil producer in Africa, Nigeria has struggled to translate its resource wealth into rising living standards.
A slump in oil prices and a sharp fall in oil production saw the country's economy slide into recession in 2016
A recent rise in oil prices has helped to spur the country's economic recovery. Addressing the situation in March this year, the International Monetary Fund (IMF)
said that although growth was again beginning to rise, "more needs to be done to reduce unemployment and address poverty."
But while the numbers of Nigerians falling into extreme poverty grows by roughly six people every minute, poverty in India continues to decrease.
At present, an estimated 5.3% of Indians or 71.5 million people, live below the poverty line.
Confined to Africa
The researchers note that 14 out of 18 countries where poverty is rising are in Africa, adding that if current rates persist, 90% of the world's poorest will be living on the continent by 2030.
Bangladesh and Indonesia are the only other non-African nations to feature among the list of 10 worst affected countries, with an estimated 17 million and 14.2 million people living in extreme poverty, respectively.
Other nations in Africa to feature on the list of 10 worst affected countries, include the Democratic Republic of Congo, with 60 million people; Ethiopia with 23.9 million people; Tanzania with 19.9 million.
Mozambique, with 17.8 million people; Kenya, with 14.7 million people; and Uganda, with 14.2 million.
