Longitudinal Ageing Study in India (LASI)

The Longitudinal Ageing Study in India (LASI) is a nationally and state representative longitudinal study of ageing and health. LASI is a national landmark, the largest in the world and, only of its kind in India. Its main goal is to provide valid, reliable and continuous scientific data on the health, social, mental and economic well-being of Indias older adult (aged 45 and above) population. These data will help to monitor existing programmes and inform new national health and ageing policies. LASI is undertaken as a globally harmonized study carried out in more than 44 developed and developing countries worldwide; and the survey schedules, protocols and methodologies are harmonized across these countries. These are part of the Health and Retirement Study (HRS) family of longitudinal ageing and retirement surveys. Therefore, LASI data will also serve as an important public resource for national policy making and worldwide comparative research on ageing. LASI is undertaken under the aegis of the Ministry of Health and Family Welfare (MoHFW), Government of India. The International Institute for Population Sciences (IIPS), Mumbai is the nodal institution for implementing LASI in collaboration with the Harvard T.H.Chan School of Public Health (HSPH) and the University of Southern California (USC).
