Over 200,000 people live in subdivided flats, according to the results of Hong Kong’s 2016 population by-census.
The Census and Statistics Department said the estimated number of subdivided flats was around 92,700. Around 209,700 people reside in such households.

The median per capita floor area of subdivided accommodation was 5.3 square metres, lower than that of public housing estates which each person would have around seven square metres.
The department said 66.9 per cent of subdivided households in 2016 were residing in units with a floor area of between seven and 13 square metres, and a median floor area of 10 square metres.

The median monthly household income of such households was HK$13,500 – lower than the HK$25,000 median for Hong Kong households overall.
