Running since 1997, the Townsend Thai Project has tracked millions of observations about the economic activities of households and institutions in Thailand. The authors offer an account of the design and implementation of the survey and tell the story not only of the origins and operations of the project but also of the challenges and rewards that come from a search to understand the process of a country's economic development.The book explains the technical details of data collection and survey instruments but emphasizes the human side of the project.
