Shenzhen

Shenzhen is a major city in Guangdong Province, China. It forms part of the Pearl River Delta megalopolis. The city is located immediately north of Hong Kong Special Administrative Region and holds sub-provincial administrative status, with powers slightly less than a province.Shenzhen was a market town of 30,000 people on the route of the Kowloon–Canton Railway. That changed in 1979 when Shenzhen was promoted to city-status and in 1980 designated China’s first Special Economic Zone (SEZ). Official statistics based on China 2010 Census put Shenzhen's total population of 10,357,938, that included migrants staying at least six months. Popular press speculate that counts do not include migrant workers living in the city which come and go daily weekly or monthly and do not stay the entire year. Such estimates put the instantaneous or sum total of individuals who have lived in Shenzhen for any length of time to at least 18 million. Shenzhen was one of the fastest-growing cities in the world during the 1990s and the 2000s. A nationwide 2015 intercensal survey (mini-census conducted every decade five years after the official census) surveyed for every city in the country recorded 11.389 million residents (9.186 million holding city residency (hukou), the remainder are considered migratory who were present at least six months of the year), while the household size increased to 2.49 people from 2.11 in 2010, indicative of soaring rents. Those not present six months of the year were not tallied.
