Assessment of Sociodemographic Disparities in Environmental Exposure Might be Erroneous due to Neighborhood Effect Averaging: Implications for Environmental Inequality Research

Kim, Junghwan; Kwan, Mei-Po

This paper examines the neighborhood effect averaging problem (NEAP) in the evaluation of sociodemographic disparities in people’s air pollution exposures in Los Angeles using GIScience methods and activity-travel diary data of 3790 individuals.

Therefore, to avoid erroneous conclusions in environmental inequality research, it would be critical to consider the NEAP in studies of
