<p>Gross Domestic Product is a good indicator for examining the economic condition of any country, but it is an inappropriate indicator for evaluating an individual's well-being. This led to our research question: what determines people's life satisfaction or well-being in a diverse country like India? The present study examines the determinants of life satisfaction in India. To conduct this study, we analysed data from five waves of the World Values Survey spanning from 1990 to 2012, in conjunction with air and water pollution data sourced from various reports by the Central Pollution Control Board (CPCB). Specifically, the study examines the influence of Sulphur Dioxide (SO₂) and Nitrogen Dioxide (NO₂) as indicators of air pollution and Biochemical Oxygen Demand (BOD) as a measure of water pollution. The impact of the socio-economic variable is as expected, like the positive impact of education, health status, social class, and marital status on life satisfaction. However, one of the paper's main objectives is to examine the effect of social capital, Environmental pollution and incidence of crime on life satisfaction. It has been found that both formal and informal social capital positively affect people's life satisfaction in India. The results show that people who are trustable and sociable are more satisfied than those who are neither. Environmental pollution, such as NO₂ and BOD, adversely affects people's satisfaction. The incidence of crime has a significant and negative impact on life satisfaction, particularly among individuals who report higher levels of satisfaction.</p>
