LASI

LONGITUDINAL AGING STUDY IN INDIA

The rapid growth of India’s elderly population has brought mounting concerns to the lack of comprehensive data on the public health, social, and economic challenges the country will soon face. The Longitudinal Aging Study in India (LASI) aims to supply the information needed to understand the circumstances surrounding India’s aging population.

With the support from National Institute on Aging (R01AG042778), LASI is a nationally-representative longitudinal survey that follows over 70,000 adults in India, aged 45 and older, over time. It represents all 35 states and union territories in India. LASI will provide a foundation for innovative, rigorous, and multidisciplinary studies of aging in India that will inform policy, support the growing elderly Indian community, and advance scientific knowledge on the following key areas:

Demographics
Health: Health, health behaviors, cognition, biomarkers, health insurance, healthcare access, utilization and financing
Economics: Employment, income, assets & debts, consumption, and retirement & pension
Social: Family, social networks, social activities

LASI is a joint effort by the Harvard T.H. Chan School of Public Health (HSPH), the International Institute for Population Sciences (IIPS) in India, and the University of Southern California (USC). It is modeled after the Health and Retirement Study (HRS) and is harmonized with the HRS and its sister studies around the world.
