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.
Urbanization in China
In 1987 China had a total of twenty-nine provincial-level administrative units directly under the central government in Beijing. In addition to the twenty-one provinces ("sheng"), there were five autonomous regions ("zizhiqu") for minority nationalities, and three special municipalities ("shi")--the three largest cities, Shanghai, Beijing, and Tianjin. (The establishment of Hainan Island as a provincial-level unit separate from Guangdong Province was scheduled in 1988.) A 1979 change in provincial-level administrative boundaries in the northeast region restored Inner Mongolia Autonomous Region to its original size (it had been reduced by a third in 1969) at the expense of Heilongjiang, Jilin, and Liaoning provinces. Urban areas were further subdivided into lower-level administrative units beginning with municipalities and extending down to the neighborhood level.
