The inner-city inhabitants and foreigners’ contribution commitment to improving air pollution: Dataset from a field survey in Hanoi

Science-based desirable solutions for mitigating and or reducing environmental pollution are of important priorities for many developed and developing countries. This article is conducted to better understand how well the inner-city citizens and foreigners perceive air pollution, how well they respond to it, and how much they willingly contribute to improving air quality in Vietnam, a lower-middle-income nation in Southeast Asia. During late 2019, a stratified random sampling technique and a contingent valuation method (CVM) were employed to survey 199 inhabitants and 75 foreigners who reside and travel within the inner-city of Hanoi, respectively. The data comprises four major groups of information, including (1) perception of air pollution and its impacts, (2) preventive measures used to mitigate polluted air, (3) commitments on willingness-to-pay (WTP) for reducing air pollution alongside reasons for the yes-or-no-WTP decision, and (4) demographic information of interviewees. The data could offer many attributes and policy implications for better economics and environmental management in the study area and or in similar places around the world.
