Public housing in Singapore is managed by the state Housing and Development Board (HDB) under a 99-year lease. The majority of the residential housing developments in Singapore are publicly governed and developed, and home to approximately 80% of the resident population. These flats are located in housing estates, which are self-contained satellite towns with well-maintained schools, supermarkets, malls, community hospitals, clinics, hawker centres (food court) and sports and recreational facilities. Every housing estate includes MRT stations and bus stops that link residents to other parts of the city-state. Some estates are also complemented by smaller LRT stations which act as a feeder service to the MRT.
