An interdisciplinary household survey in Chengdu, led by China Project Executive Director Chris NIELSEN, Prof. James HAMMITT (Harvard T.H. Chan School of Public Health), and Profs. SHEN Mingming and YAN Jie (Research Center for Contemporary China, School of Government, Peking University), was completed in July 2016. Other collaborators included China Project research affiliates Sumeeta SRINIVASAN (Department of Urban and Environmental Policy and Planning, Tufts University), GUAN ChengHe (Graduate School of Design, Harvard University), and WANG Haikun (School of Environment, Nanjing University).
The data have now been joined with an earlier dataset collected in a nearly identical Harvard China Project-PKU survey in 2005, to yield a time series covering Chengdu's economic growth, urbanization, and transit development over 11 years.
Both the 2005 and 2016 surveys collected data across a wide range of research interests, including transportation planning, travel behavior, mobile-source emissions, outdoor and indoor air pollution exposures, health effects of air pollution, and perceptions and valuation of health risk. Harvard researchers devised the questionnaires and are leading a number of parallel analyses. Covering 2000 households, field implementation of both surveys was led by political scientist Shen, using RCCC's rigorous geospatial sampling methods to insure inclusion of non-registered migrants left out of most social surveys in China.
