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
The People's Republic of China is divided into 22 provinces, five autonomous regions, each with a designated minority group; four municipalities; and two special administrative regions (SARs) which enjoy a degree of political autonomy. These 31 provincial-level divisions can be collectively referred to as "mainland China", a term which usually excludes two SARs of Hong Kong and Macau. Geographically, all 31 provincial divisions can be grouped into six regions, including North China, Northeast China, East China, South Central China, Southwest China and Northwest China.
