Multiple ethnic groups populate China, where "China" is taken to mean areas controlled by either of the two states using "China" in their formal names, the People's Republic of China (PRC) and the Republic of China ("Taiwan").

The Han Chinese are the largest ethnic group, where some 91.59% of the population was classified as Han Chinese (~1.2 billion). Besides the majority Han Chinese, 55 other ethnic groups are recognised in mainland China by the PRC government, numbering approximately 105 million people, mostly concentrated in the northwest, north, northeast, south, and southwest but with some in central interior areas.

The major minority ethnic groups are Zhuang (16.9 million), Hui (10.5 million), Manchu (10.3 million), Uyghur (10 million), Miao (9.4 million), Yi (8.7 million), Tujia (8.3 million), Tibetan (6.2 million), Mongol (5.9 million), Dong (2.8 million), Buyei (2.8 million), Yao (2.7 million), Bai (1.9 million), Korean (1.8 million), Hani (1.6 million), Li (1.4 million), Kazakh (1.4 million), and Dai (1.2 million).
