China food security comprehensive assessment dataset 2012–2022

Ensuring food security is an eternal issue in the development process of human society, and as a major global grain-producing country, China has played an important role in stabilizing world food security. However, China's food security is facing new challenges in the context of the new development pattern, and the existing grain statistics are fragmented and not comprehensive enough to meet the needs of current food security assessment studies. In this study, we constructed the time-series China food security comprehensive assessment dataset (CFSAD), which includes five categories of grain, rice, wheat, maize and soybean, and covers five dimensions of the basic guarantee level, the market operation situation, the scientific and technological support capacity, the resource and environmental conditions, and the level of purchasing power, and includes fourteen indicators. Our dataset enables a more scientific and comprehensive assessment of China's food security situation, which can provide data support for effective government policy making and academic research.
