Squatting in Thailand was traditionally permissible under customary law and adverse possession can occur after ten years of continuous occupation. As of 2015, the capital Bangkok had over 2 million squatters, out of a population of around 10 million. A survey of slums across the country noted in 2000 that most were rented not squatted; Khlong Toei District in Bangkok contains both squatters and tenants. There are also squatters in rural areas. The 1975 Agricultural Land Reform Act aimed to redistribute land to poor people (including squatters) under the Sor Por Kor program and as of 2019, 36 million rai (5.8 million ha; 14 million acres) of land had been assigned.
