Ageing populations: new challenges in longevity.

ABSTRACT:

Background

High-income countries experienced unprecedented gains in life expectancy throughout the twentieth century. However, recent evidence suggests that these gains have slowed, especially at older ages. This paper focuses on recent trends in life expectancy and health in ageing populations in high-income countries.

Methods

We analysed mortality and health data from the Human Mortality Database and the Global Burden of Disease.

Findings

Although life expectancy continues to rise in high-income countries, the pace of improvement
