Housing policy dating back to the early stages of the Cold War instigated the incorporation of basement air raid shelters into newly built residential buildings. Encouraged by Deng Xiaoping's economic reforms, migrant workers began emigrating from rural areas to more urban ones, lured by the benefits of higher salaries and standards of living. To accommodate the population surge, the Chinese government permitted the use of these shelters as residences. Without a valid residential permit many migrants were unable to afford the cost of purchasing their own home on arrival and instead turned towards these low cost rooms.[4]
In late 2010, the term "鼠族" began being used to describe underground dwellers in the Chinese press. Shortly after, the Ministry of Housing and Urban-Rural Development formally banned residential rentals of basements and air raid shelters due to safety concerns. By early 2015, state media had reported that 120,000 people had been evicted from underground residences.[5]
Accommodation
While still illegal, many migrant workers choose to live in these centrally located conditions to avoid a longer commute to their workplace.[6] According to a 2013 study, the median area for an underground room in Beijing was 9.75 square metres (104.9 sq ft) and the average price was 436 yuan per month.[4] Hygiene conditions in these residences are generally poor, with shared communal facilities.[7][8] In one instance, people across 80 rooms had access to a single toilet.[9]
