The article discusses a study which investigated the levels and trends in child mortality in 187 countries from 1970 to 2010. Study authors utilized a database containing 16,174 measurements of mortality in children younger than five years and used Gaussian process regression to generate estimates. They found that the worldwide mortality of children younger than five years decreased from 11.9 million in 1990 to 7.7 million in 2010. Global decline in neonatal mortality was 2.1 percent, 2.3 percent in postneonatal mortality and 2.2 percent in childhood mortality. Study authors also concluded that the declining rates of child mortality should be given more policy attention.
