The report finds that although average human development improved significantly across all regions from 1990 to 2015, one in three people worldwide continue to live in low levels of human development as measured by the Human Development Index (HDI). The HDI is a summary measure of average achievement in key dimensions of human development: having a long and healthy life, being knowledgeable, and enjoying a decent standard of living. Despite improvements in sub-Saharan Africa over the past two decades, almost 60 percent of people still experience deprivations in these three areas. Around a third of children under the age of five are malnourished and affected by stunting. Over 35 percent of adults are illiterate. Some 70 percent of working adults earn less than US$ 3.10 per day.
