The 2013 report showed that global life expectancy for both sexes increased from 65.3 years in 1990, to 71.5 years in 2013, while the number of deaths increased from 47.5 million to 54.9 million over the same interval. Progress varied widely across demographic and national groups. Reductions in age-standardised death rates for cardiovascular diseases and cancers in high-income regions, and reductions in child deaths from diarrhoea, lower respiratory infections and neonatal causes in low-income regions drove the changes. HIV/AIDS reduced life expectancy in southern sub-Saharan Africa.
