  • The Lancet Nigeria Commission

    Open AccessIbrahim Abubakar, Sarah L Dalglish et al.ARTICLEThe Lancet2022

    Health is central to the development of any country. Nigeria’s gross domestic product is the largest in Africa, but its per capita income of about ₦770 000 (US$2000) is low with a highly inequitable distribution of income, wealth, and therefore, health. It is a picture of poverty amidst plenty. Nigeria is both a wealthy country and a very poor one. About 40% of Nigerians live in poverty, in social conditions that create ill health, and with the e…
