Tsinghua Urban Health Index (TUHI) is an ongoing third-party evaluation project on city health levels in response to the "Healthy China 2030" strategy and the "Healthy China Initiative". The project was launched in March 2020 and led by Tsinghua University's Institute for China Sustainable Urbanization in collaboration with Vanke School of Public Health. Under the guidance of the National Health Commission of the People's Republic of China, the first version of the report "Tsinghua Urban Health Index (2020)" was published in December of that year, for the first time realising a panoramic evaluation of the comprehensive health levels of 80 major cities in China. In December 2021, the project research team released "Tsinghua Urban Health Index (2021)", which covered 90 major cities from China provincial units except for Hong Kong, Macao and Taiwan. In 2022, the project team further optimised the evaluation methods and expanded the data sources to produce the "Tsinghua Urban Health Index (2022)", which for the first time achieved full coverage of 296 cities above prefectural level in China.
