On 14 December 1990, the United Nations General Assembly designated October 1 as the International Day of Older Persons (resolution 45/106). This was preceded by initiatives such as the Vienna International Plan of Action on Ageing, which was adopted by the 1982 World Assembly on Ageing and endorsed later that year by the UN General Assembly.
In 1991, the General Assembly adopted the United Nations Principles for Older Persons (resolution 46/91). In 2002, the Second World Assembly on Ageing adopted the Madrid International Plan of Action on Ageing, to respond to the opportunities and challenges of population ageing in the 21st century and to promote the development of a society for all ages.
The 2021 theme “Digital Equity for All Ages” affirms the need for access and meaningful participation in the digital world by older persons.
