In recent years, excessive exposure to ambient air pollution posed a serious threat to public health and might greatly increase the risk of illness for residents. Different age and sex group cohorts have inequality health risks to air pollution. Ozone and PM2.5 are the most two serious air pollutants in the Pearl River Delta Metropolitan Region (PRD). We used the daily PM2.5 concentration data and maximum 8-hour ozone concentration data from PRD’s 55 stations in 2015 and socioeconomic data such as census data and economic static data. Spatio-temporal kriging (STK) model was used to analyze the air pollutants variation characteristics of the spatiotemporal distribution. The ecological factor-cluster analysis is used to identify neighborhoods’ social zones of PRD based on the demographic properties, physical facilities properties, and socioeconomic properties. Associations between ambient air pollution and socioeconomic characteristics, ethnicity and age profile of neighborhoods in PRD are discussed.
