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
Health: Health, health behaviors, cognition, biomarkers, health insurance, healthcare access, utilization and financing
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.
