The figures also project that girls born in the UK in 2023 can expect to live on average to an age of 90.0 years and boys to 86.7 years, increasing to 92.2 years and 89.3 years respectively for babies born in 2047.
Kerry Gadsdon of the ONS said: “Boys born in the UK in 2023 can expect to live on average to age 86.7 years, and girls to live to 90.0 years, taking into account projected changes in mortality patterns over their lifetime.
Females aged 65 in the UK in 2023 can expect to live a further 22.5 years, while males can expect to live another 19.8 years, projected to rise to 24.4 years and 21.8 years respectively by 2047.
About one in five girls born in the UK in 2030 is projected to live on average to at least 100 years old, rising to almost one in four by 2047, new figures suggest.
The gap between male and female life expectancy at birth has fallen from 4.4 years in 1981 to 3.4 years in 2023 and is projected to fall further in the future.
