In 2020, the number of people aged 60 and above rose to 1 billion, almost 15% of the world’s population. And this proportion is growing, as people live longer. In the same week that the United Nations General Assembly declared 2021-2030 the Decade of Healthy Ageing, WHO released the Baseline report for the Decade of Healthy Ageing, which provides a snapshot of where we are in 2020 and where we aim to be by 2030. The report brings together data available for measuring healthy ageing, presents the experience of countries that have been successful in starting healthy ageing initiatives, and discusses what is needed to promote collaboration and better measure progress towards healthy ageing.
