## Research and data to make progress against the world’s largest problems.Child mortality rate Long-run estimates combining data from UN & Gapminder#### What share of children die before their fifth birthday?What could be more tragic than the death of a young child? Child mortality, the death of children under the age of five, is still extremely common in our world today.The historical data makes clear that it doesn’t have to be this way: it is possible for societies to protect their children and reduce child mortality to very low rates. For child mortality to reach low levels, many things have to go right at the same time: good healthcare, good nutrition, clean water and sanitation, maternal health, and high living standards. We can, therefore, think of child mortality as a proxy indicator of a country’s living conditions.The chart shows our long-run data on child mortality, which allows you to see how child mortality has changed in countries around the world.Share of population living in extreme poverty World BankLife expectancy Long-run estimates collated from multiple sources by Our World in DataCO₂ emissions per capita Long-run estimates from the Global Carbon BudgetGDP per capita Long-run estimates from the Maddison Project DatabaseShare of people who are undernourished UN FAOLiteracy rate Long-run estimates collated from multiple sources by Our World in DataShare of the population with access to electricity World Bank## Data explorersInteractive visualization tools to explore a wide range of related indicators.Data Explorer](https://ourworldindata.org/explorers/poverty-explorer)Data Explorer](https://ourworldindata.org/explorers/population-and-demography)Data Explorer](https://ourworldindata.org/explorers/global-health)## All our topicsAll our data, research, and writing — topic by topic.## Population and Demographic Change## Health* Neglected Tropical Diseases* Antibiotics & Antibiotic Resistance## Energy and Environment
