On March 18, 2021, the Global Report on Ageism was launched by the World Health Organization (WHO), the Office of the UN High Commissioner for Human Rights, the UN Department of Economic and Social Affairs, and the UN Population Fund. Combating ageism is one of the four action areas of the Decade of Healthy Ageing (2021–2030), a global collaboration that brings together governments and various partners to improve the lives of older people, their families, and the communities in which they live. Changing how we think, feel, and act towards age and ageing is a prerequisite for successful action on healthy ageing and for progress on the three other action areas: developing communities that foster older people’s abilities, delivering person-centered integrated care and primary health services responsive to older people’s needs, and providing long-term care for older people who need it.
