LASI Pilot
In 2010, LASI pilot survey was conducted successfully with targeted sample of 1,600 individuals aged 45 and older along with their spouses, and this helped in design and rollout of a full-scale, nationally representative LASI survey. The expectation is that LASI will be a biennial survey and will be representative of Indians aged 45 and older, with no upper age limit. The age of 45 is chosen to (a) harmonize this survey with its sister HRS surveys in Asia; and (b) allow measurement of pre-retirement behavior, as people often begin to change their labor market, health, and consumption behaviors as they age.
1,600 age-qualifying individuals were drawn using stratified, multistage area probability sampling design. After a series of pre-pilot studies designed to test the instrument and the key ideas behind it, the pilot data were collected through face-to-face interviews over period of three months. Descriptive analysis of the data has been performed and lessons drawn used to inform the launching of a full-scale LASI survey.
The LASI pilot survey was conducted in four states: Karnataka, Kerala, Punjab, and Rajasthan. To capture regional variation, we have included two northern states (Punjab and Rajasthan) and two southern states (Karnataka and Kerala). Karnataka and Rajasthan were included in the Study on Global Ageing and Adult Health (SAGE), which enable us to compare our findings with the SAGE data. The inclusion of Kerala and Punjab demonstrates our aim to obtain a broader representation of India, where geographic variations accompanied by socioeconomic and cultural differences call for careful study and deliberation. Punjab is an example of an economically developed state, while Rajasthan is relatively poor, with very low female literacy, high fertility, and persisting gender disparities. Kerala, which is known for its relatively efficient health care system, has undergone rapid social development and is included as a potential harbinger of how other Indian states might evolve.
