Over the last 10 years, Nigeria has experienced the largest surge in population worldwide, adding 50 million people, according to recent demographic data.
This remarkable growth highlights Nigeria’s status as Africa’s most populous country and underscores challenges and opportunities facing its economy and infrastructure.
Pakistan ranked second with a population increase of 38 million, followed closely by India at 35 million new residents.
Indonesia and Ethiopia also registered significant population gains of 30 million and 25 million respectively, reflecting strong demographic growth across Asia and Africa.
Other countries with notable population rises include Bangladesh (+20 million), Egypt (+18 million), the Philippines (+15 million), Tanzania (+12 million), and both Vietnam and the Democratic Republic of Congo (+10 million each). Uganda, Türkiye, Iran, Myanmar, Mexico, Kenya, and Sudan experienced smaller but still substantial increases ranging from 5 to 9 million.
These population trends have major implications for urban planning, healthcare, education, and labor markets in fast-growing nations.
As Nigeria and other countries cope with rapid demographic changes, policymakers face pressing demands to expand social services and create sustainable economic opportunities for their burgeoning populations.
