Guangdong
Guangdong (; formerly romanised as Kwangtung or Canton Province) is a province in South China, on the South China Sea coast. Guangdong surpassed Henan and Shandong to become the most populous province in China in January 2005, registering 79.1 million permanent residents and 31 million migrants who lived in the province for at least six months of the year; the total population was 104,303,132 in the 2010 census, accounting for 7.79 percent of Mainland China's population. This also makes it the most populous first-level administrative subdivision of any country outside of South Asia, as its population is surpassed only by those of the Pakistani province of Punjab and the Indian states of Bihar, Maharashtra and Uttar Pradesh. The provincial capital Guangzhou and economic hub Shenzhen are among the most populous and important cities in China. The population increase since the census has been modest, the province registering 108,500,000 people in 2015.
China proper
However, Han Chinese areas in the present day do not correspond well to the Eighteen Provinces of the Qing Dynasty. Much of southwestern China, such as areas in the provinces of Yunnan, Guangxi, and Guizhou, was part of successive Han Chinese dynasties, including the Ming Dynasty and the Eighteen Provinces of the Qing Dynasty. However, these areas were and continue to be populated by various non-Han Chinese minority groups, such as the Zhuang, the Miao people, and the Bouyei. Conversely, today Han Chinese form the majority in most of Manchuria, much of Inner Mongolia, many areas in Xinjiang and scattered parts of Tibet, not least due to the expansion of Han Chinese settlement encouraged by the late Qing dynasty, the Republic of China, and the People's Republic of China.
