Compared with 2017, UK male life expectancy at birth fell slightly by 2.1 weeks and UK female life expectancy at birth fell by 2.6 weeks.
The decline seen from 2017 to 2018 was the first decline seen since 2014 to 2015, where life expectancy at birth in the UK fell by 11.0 weeks for males and 14.6 weeks for females.
Single-year life tables have been published as a result of evidence of user need for single-year data; they are suited for analyses that require annual data and need more detailed information about mortality patterns.
Single-year life tables are not National Statistics; they are considered less robust than the three-year life tables as they are more prone to annual fluctuations in deaths caused by seasonal events.
We recommend that single-year life tables should be used alongside the three-year national life tables to draw conclusions about longer-term trends.
Users should exercise caution when considering using single-year life tables to look at trends for UK constituent countries; the relatively small size of the populations of Northern Ireland, Scotland and Wales makes the annual life expectancy data for these countries more volatile.
