The mortality rate in children aged from 1 to 4 years. This is a type of central death rate. Alternatively, it is the probability of dying between the first and fifth birthday. In low- and middle-income countries, these rates can be estimated using data from Demographic and Health Surveys or from Sample Registration Systems because vital registration systems are not usually sufficiently complete to allow direct measurement. Given the uncertainty of such estimated rates, it is wise to confirm their provenance and to interpret them cautiously. Mortality rates in this age range are a sensitive indicator of vulnerability to nutritional deficiencies and childhood infections. See also under 5 mortality rate.
