Autonomous prefectures (Chinese: 自治州; pinyin: zìzhìzhōu) are one type of autonomous administrative division in China, existing at the prefectural level, with either ethnic minorities forming over 50% of the population or being, most commonly, the historic home of significant minorities. The official name of an autonomous prefecture includes the most significant minority in that region, sometimes two, rarely three. For example, a prefecture with a large number of Kazakhs (Kazak in official naming system) may be called a Kazak Autonomous Prefecture. Like all other prefectural level divisions, autonomous prefectures are divided into county level divisions. There is one exception: Ili Kazak Autonomous Prefecture contains two prefectures of its own. Under the Constitution of the People's Republic of China, autonomous prefectures cannot be abolished.^{[citation needed]}
