Summary

The Global South, that groups together low- or middle- income countries mainly located in Africa, Asia and Latin America, concentrates most of the world population. Population ageing, caused by the demographic transition and a large decrease in fertility and mortality rates, make these countries face numerous challenges. Among regions in the Global South, the differences in life expectancy at birth were still large in 2022: almost 74 years in Latin America and the Caribbean but only 60 years in sub-Saharan Africa, with some countries barely exceeding 50. Due to many factors that play on health transition, high mortality countries suffer a cumulative burden from both infectious and non-communicable diseases (NCDs). In addition, the lack of old-age mortality data is a dramatic issue when studying longevity in these countries.
