The data set contains child mortality rates at national level from the year 1952 to 2022. The data used to calculate the yearly mortality rates was obtained from the last eight Kenya-Demographic health surveys, DHS 1984, DHS 1989, DHS 1993, DHS 1998, DHS 2003, DHS 2008/09, DHS 2014, DHS 2022. Children aged 5 years and below from these surveys were combined to produce the estimate of the mortality rates.
