DOHFI is based in the most populous city (Lagos) in the most populous country (Nigeria) of the world’s poorest continent (Africa). Sadly, since June 2018 Nigeria has also acquired the inglorious distinction of being the poverty capital of the world, having overtaken India as the nation with the largest number of people living on less than two dollars per day. Nigeria ended 2018 with 90.8 million people living in extreme poverty, representing about 50% of its estimated 180 million population.

As Nigeria expects a major boom in its population —it will become the world’s third largest country by 2050—it’s a problem that will likely worsen. But having large populations of people still living in extreme poverty is an Africa-wide problem. Significantly, of those countries in top ten, only one (Ethiopia) is on track to meet the United Nations’ SDG of ending extreme poverty by 2030.

Outside the top ten, only two (Mauritania and Ghana) are also on track with the SDG target. Indeed, of the 15 countries across the world where extreme poverty is increasing, 13 are in Africa (World Poverty Clock data).


The epidemic of oral and dental morbidity in Nigeria is one aspect of the evil triad of poverty, ignorance and disease.
