Abstract
Solutions for mitigating and reducing environmental pollution are important priorities for many developed and developing countries. This study was conducted to better understand the degree to which inner-city citizens and foreigners perceive air pollution and respond to it, particularly how much they willingly contribute to improving air quality in Vietnam, a lower-middle-income nation in Southeast Asia. During mid-December 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. The data comprises four major groups of information on: (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 findings and data of this study could offer many policy implications for better environmental management in the study area and beyond.

Summary
Air pollution is regarded as a significant public health concern. In 2016, data from the World Health Organization (WHO) showed that 91% of the world’s population resided in places where the air contained dangerous levels of pollutants, exceeding the WHO guideline limits [1]. The four tables (Tables 2–5) present the statistics descriptions of willingness-topay for air pollution reduction values associated with five major dimensions, including demographic information (Table 2), inhabitants’ perception of air quality (Table 3), severity and impacts of polluted air (Table 4), and respondent’s preventive measures for reducing exposure to air pollution (Table 5) In these tables, we only include inhabitants who were willing to offer a positive contribution to the air protection fund. Education, and WTP values, we observed nonlinear relationships since the willingness to pay for air pollution reduction fluctuates across age groups and the highest educational level attained Still, it seems that relatively old respondents offered fewer financial commitments than their younger counterparts.
