The research project has been carried out jointly by the Leibniz Universität Hannover (LUH) and the University of Göttingen (UGö) in close cooperation with research communities in Thailand and Vietnam. As indicated in Figure 1, the TVSEP project continues the work of the DFG Research Unit (FOR 756). Thus, from 2007 to 2022, nine surveys covering about 4,400 households in 440 villages in six provinces in Thailand and Vietnam were conducted. In addition, a special COVID-19 pandemic survey was conducted in Thailand in 2020/21. Furthermore, six village head surveys were conducted in Thailand and five in Vietnam plus migrant tracking surveys in both countries.

This project aims to extend the panel household surveys in Thailand and Vietnam to generate a deeper understanding of the development of income and poverty in their rapidly transforming rural areas. Achieving high data quality is one of the major guiding principles of the data collection process. These datasets are made available to the international research community. Special attention is paid to the capacity building and outreach to the research communities in Thailand and Vietnam. Apart from research, the data will ease policy-making with the goal of improving quality of life in the rural areas.

Study sites

The data is collected in three provinces of Thailand (Nakhon Phanom, Ubon Ratchathani, Buriram) and three provinces of Vietnam (Ha Tinh, Thua Thien Hue, Dak Lak) (see Figure 2).
