Rooftop slum

According to the Hong Kong population census, there were 47,091 rooftop dwellers in 2011 and this number is likely to have dropped as working class areas are redeveloped.

[5] Many of these squats were to be found in the old Kowloon districts of Sham Shui Po, Kwun Tong, and Tai Kok Tsui.

[6] The rooftop dwellings, generally built atop tenement buildings from the 1950s and 1960s, typically range from 97 to 301 square feet (9.0 to 28.0 m2).

[1][6] The shanty homes are contrasted against legal apartments of Hong Kong, the "world's most expensive luxury city".

The number of illegal dwellings has reduced dramatically as working class areas of Hong Kong are redeveloped.
