Life expectancy at birth in the UK in 2017 to 2019 was 79.4 years for males and 83.1 years for females; slight improvements were observed from 2016 to 2018 of 6.3 weeks and 7.3 weeks for males and females respectively.
The relatively low increases in life expectancy at birth in 2017 to 2019 suggest a continuation of a trend observed since 2011, where annual life expectancy improvements have slowed down in comparison with the previous decade.
In comparison with selected Organisation for Economic Co-operation and Development (OECD) countries for which data are available, England, Wales and Scotland have among the lowest annual improvements in life expectancy at birth for both males and females.
