Kalyanpur Pora Bostee (KPB) KPB is a slum (known locally as a bostee) of 20,000 people living in flimsy shacks made of corrugated steel and bamboo poles. The dwellings average nine square metres, usually just a single room accommodating an average of four people, commonly two parents and two children. The shacks are fragile, uninsulated, without windows, and are blackened by smoke. The people who live there have no security of tenure, so they live in constant fear of eviction. They suffer from over-priced illegal electricity and inadequate water supply and sanitation. The average income for residents is about AU$1,800 per annum. KPB’s residents lead a life of exclusion and serious material deprivation.
