Gains have been made in child survival since 1990, making it possible to increase child survival for future generations. Worldwide, the mortality rate for children under five dropped by 47 per cent—from 90 deaths per 1,000 live births in 1990 to 48 in 2012. Despite this accomplishment, more rapid progress is needed to meet the 2015 target of a two-thirds reduction in under-five mortality. In 2012, an estimated 6.6 million children—18,000 a day—died from mostly preventable diseases. These children tend to be among the poorest and most marginalized in society.
