Tai Kok Tsui
According to the Hong Kong population census, there were 47,091 rooftop dwellers in 2011, 48,570 in 2006 and 77,930 in 2001. Many of these squats were to be found in the old Kowloon districts of Sham Shui Po, Kwun Tong, and Tai Kok Tsui. For example, the Hoi On Building in Tai Kok Tsui housed over 100 people living on the roof in shacks. Some were made out of rudimentary materials such as wood, others were constructed more sturdily with brick walls and air-conditioning.
