This study tries to find evidence of environmental inequity by looking into the relationship between socio-economic characteristics and air pollution exposure. This is carried out by first computing a household specific air pollution exposure index for 347 households around seven pollution monitoring stations in Delhi. The index is then used in a multivariate regression to look into the environmental equity aspect. The analysis yields that the economically backward communities are the most affected by the exposure to air pollution. However, the study does not find any evidence of environmental inequity due to religion and social backwardness. Education facilitates defence against the exposure, when it crosses a threshold level. The separate analysis of residential and industrial areas suggests that exposure to air pollution is dependent, though not systematically, on the location of residence, besides socio-economic status.
