According to the World Health Organization (WHO) 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. the environments in which we live can favor health or be harmful to it. Environments are highly influential on our behavior 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. Societies that adapt to this changing demographic and invest in healthy ageing can enable individuals to live both longer and healthier lives and for societies to reap the dividends. – WHO
