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.
