Many Hong Kong families live in very small houses. Some houses are even smaller than prison cells. The average space was 4.6 square meters for one person. This is half the size of a car parking space. The average size of a prison cell is 50 percent bigger than the size of the houses. Last year, over 65 percent of Hong Kong families live in houses that range between 7 and 14 square meters. Hong Kong has some of the world's most expensive houses. People must save money for 18 years to buy a tiny house. One person said it was "unacceptable and inhumane" that living place are smaller than prison cells in a rich city like Hong Kong.
