Study on Global Ageing and Adult Health
The Study on Global AGEing and Adult Health
(SAGE) was developed as part of a Longitudinal Survey Programme to compile comprehensive information on the health and well-being of adult populations and the aging process. The core SAGE collects data on respondents 18 or older, with an emphasis on those 50 or older, from nationally representatives in six nations (China, Ghana, India, Mexico, Russia, and South Africa). Data topics include income, work, health care, well-being, and biomarkers.
