Counties of China
Counties, formally county-level divisions, are found in the third level of the administrative hierarchy in Provinces and Autonomous regions, and the second level in municipalities and Hainan, a level that is known as "county level" and also contains autonomous counties, county-level cities, banners, autonomous banner, and City districts. There are 1,464 counties in Mainland China out of a total of 2,862 county-level divisions.
Xian have existed since the Warring States period, and were established nationwide during the Qin Dynasty. The term xian is usually translated as "districts" or "prefectures" when put in the context of Chinese history. This article, however, will try to keep the terminology consistent with the modern translation, and use the term "county" throughout, though this is not conventional practice in Sinology literature.
Xian have existed since the Warring States period and were set up nationwide by the Qin Dynasty. The number of counties in China proper gradually increased from dynasty to dynasty. As Qin Shi Huang reorganized the counties after his unification, there were about 1,000. Under the Eastern Han Dynasty, the number of counties increased to above 1,000. About 1400 existed when the Sui dynasty abolished the commandery level (郡 jùn), which was the level just above counties, and demoted some commanderies to counties. The current number of counties mostly resembled that of the later years of Qing Dynasty. Changes of location and names of counties in Chinese history have been a major field of research in Chinese historical geography, especially from the 1960s to the 1980s.
