The world is facing the arrival of an aging society.
Every person – in every country in the world – should have the opportunity to live a long and healthy life. Yet, the environments in which we live can favour health or be harmful to it. Environments are highly influential on our behaviour and our exposure to health risks (for example, air pollution or violence), our access to services (for example, health and social care) and the opportunities that ageing brings.
The number and proportion of people aged 60 years and older in the population is increasing. In 2019, the number of people aged 60 years and older was 1 billion. This number will increase to 1.4 billion by 2030 and 2.1 billion by 2050. This increase is occurring at an unprecedented pace and will accelerate in coming decades, particularly in developing countries.
This historically significant change in the global population requires adaptations to the way societies are structured across all sectors. For example, health and social care, transportation, housing and urban planning. Working to make the world more age-friendly is an essential and urgent part of our changing demographics.
