This report aims to outline the current available knowledge on the health and wellbeing of older persons in the Region of the Americas during the United Nations Decade of Healthy Ageing (2021-2030). It also seeks to guide political actions towards ensuring the human rights of older persons, and describes the negotiation and drafting process behind the Inter-American Convention on Protecting the Human Rights of Older Persons. It reports on the doctrinal and legal developments that led the Region of the Americas to draft the Convention and describes its action areas and guaranteed rights, as well as the obligations assumed by the States Parties. The Convention is an essential tool to advance the strategies of the Decade of Healthy Ageing. This publication reflects on the importance of having a major legal instrument for this purpose at the international level. The demographic transition in Latin America and the Caribbean will continue to shape the ability of countries and health systems to respond to the needs of the population. Given this reality, international instruments will be needed to guarantee the full enjoyment of the human rights of older persons. In order to design inclusive and sustainable systems, accurate, updated, and effective information is required. The Decade of Healthy Ageing––the initiative that constitutes the framework for this document––is a strategic period in which to focus on data generation and monitoring.
