Notes:

• The infant mortality rate is calculated based on the number of deaths under 1 year per 1,000 births. The chart shows the infant mortality rate in the United Kingdom from 1930 to 2019.
• The infant mortality rates for the United Kingdom are calculated by including births in Northern Ireland to non-residents in the denominator.
• Death figures are based on deaths registered rather than deaths occurring in a calendar year.
