a prison for over 100 years. In Thailand, although evictions have reduced their visibility or numbers in urban areas, many squatters still occupy land near railroad tracks, under overpasses, and waterways. Commercial squatting is common in Thailand, where businesses temporarily seize nearby public real estate (such as sidewalks, roadsides, beaches, etc.) and roll out their enterprise, and at closing time they fold it in and lock it up, thus avoiding the extra cost of having to rent more property. In the early 2000s, the government estimated that 37% of the population lived in low-income urban communities, over half of which were squatting public land or renting precariously. The National Housing Authority stated over 100,000 families were living under threat of immediate eviction. Hong Kong and Chinese mainland In China, informal settlements are known as urban villages. Squatter settlements occurred in Hong Kong in 1946, after its wartime occupation by Japan. After 700,000 people migrated from mainland China to Hong Kong between 1949 and 1950; the squatter population was estimated at 300,000, with people sleeping wherever they could find a space. A fire at Shek Kip Mei in December 1953 resulted in over 50,000 slum-dwellers being left homeless. Rooftop slums then developed, when people began to live illegally on the roofs of urban buildings. In addition, the Kowloon Walled City became an area for squatters, housing up to 50,000 people in Hong Kong. India In Mumbai there are an estimated 10 to 12 million inhabitants, and six million of them are squatters. The squatters live in a variety of ways. Some possess two- or three-story homes built out of brick and concrete which they have inhabited for years. Geeta Nagar is a squatter village based beside the Indian Navy compound at Colaba. Squatter Colony in Malad East has existed since 1962, and now, people living there pay a rent to the city council of 100 rupees a month. Dharavi is a community of one million squatters. The stores and factories situated there are mainly illegal and so are unregulated, but it is suggested that they do over $1 million in business every day. Other squatters are pavement dwellers, with very few possessions. Activists such as Jockin Arputham, Prema Gopalan and Sheela Patel are working for better living conditions for slum dwellers, through organisations such as Mahila Milan and Slum Dwellers International.
