The infant mortality rate is based on the number of children that die between birth and age one, per 1,000 live births. It is a common measure of population and healthcare quality but is also influenced by social, economic and environmental factors (OECD, 2014).
Notes for OSN data:
United Kingdom - Infant and neonatal mortality rates for the United Kingdom are calculated by including births in Northern Ireland to non-residents in the denominator.
Northern Ireland - The infant mortality and neonatal mortality rates for Northern Ireland represent the rate per 1,000 live births including non-Northern Ireland resident births.
