The article examines Britain's health trends over a 25-year period through the lens of period life expectancy, which estimates lifespan based on current mortality rates. Two critical shifts were identified: a significant deceleration in life expectancy improvements beginning around 2011, and an unprecedented decline in 2020 due to the COVID-19 pandemic. Experts across multiple health disciplines assessed changes in the nation's overall well-being during this quarter century.


The slowdown in life expectancy improvements before the pandemic suggests underlying health system or societal challenges that require attention. Understanding these trends helps policymakers identify areas needing intervention and allows public health officials to develop targeted strategies for improving population health outcomes.

A good way to follow the health of a nation is to glance at what is known as period life expectancy. This calculates how long a person born today would live if the current death rates remained exactly the same for the rest of their life. This had two major turning points in the UK over the period: a marked slowdown in improvements from around 2011 and a sharp, historically unprecedented fall in 2020 during the COVID-19 pandemic.
