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.<\/jats:p>","DOI":"10.3390\/data6040039","type":"journal-article","created":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T03:04:06Z","timestamp":1618196646000},"page":"39","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Exploring Inner-City Residents\u2019 and Foreigners\u2019 Commitment to Improving Air Pollution: Evidence from a Field Survey in Hanoi, Vietnam"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0790-1576","authenticated-orcid":false,"given":"Quan-Hoang","family":"Vuong","sequence":"first","affiliation":[{"name":"Centre for Interdisciplinary Social Research, Phenikaa University, Hanoi 100000, Vietnam"}]},{"given":"Tri Vu","family":"Phu","sequence":"additional","affiliation":[{"name":"Faculty of Economics and Business, Phenikaa University, Hanoi 12116, Vietnam"}]},{"given":"Tuyet-Anh T.","family":"Le","sequence":"additional","affiliation":[{"name":"School of Science and the Environment, Grenfell Campus, Corner Brook, Memorial University of Newfoundland, St. John\u2019s, NL A2H 5G4, Canada"},{"name":"Forestry Economics Research Centre, Vietnamese Academy of Forest Sciences, Duc Thang, Bac Tu Liem, Hanoi 11910, Vietnam"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9516-2413","authenticated-orcid":false,"given":"Quy","family":"Van Khuc","sequence":"additional","affiliation":[{"name":"Faculty of Economics and Business, Phenikaa University, Hanoi 12116, Vietnam"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,10]]},"reference":[{"key":"ref_1","unstructured":"(2021, April 08).
