While the world was gripped by the unfolding COVID-19 pandemic in 2020, children continued to face the same crisis they have for decades: intolerably high mortality rates and vastly inequitable chances at life. In total, more than 5.0 million children under age 5, including 2.4 million newborns, along with 2.2 million children and youth aged 5 to 24 years – 43 per cent of whom are adolescents – died in 2020. This tragic and massive loss of life, most of which was due to preventable or treatable causes, is a stark reminder of the urgent need to end preventable deaths of children and young people. Data gaps remain a serious challenge to child mortality estimation and monitoring. Almost two thirds of low and middle income countries (97 out of 135) have no reliable mortality data in the past three years. And just 40 countries had high-quality national data for 2020 included in the estimation model, though national or subnational data were available for more than 80 countries or areas to help analyse excess mortality due to COVID-19.
