This document outlines the transition from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs) and discusses the implications for Nigeria's economy and child health. It provides an overview of the MDGs, including the 8 goals and related targets and indicators. Globally, the document notes that extreme poverty was reduced and access to water increased, but goals on child mortality, maternal health and infectious diseases were only partially met. In Nigeria, child undernutrition and mortality declined but still remain high. The transition to the SDGs faces challenges but also opportunities to further improve health and economic outcomes.
