From 1960 to 1992, the government transferred some 328,000 families to resettlement sites 25–40 km from Metro Manila. According to the Asian Coalition on Housing Rights, during Corazon C. Aquino's time, the government would bring some 100,000 persons to relocation sites yearly. During the said period, Sapang Palay and Carmona had a 60% abandonment rate. Congress enacted RA 7279 or the Urban Development and Housing Act (UDHA) in 1992. The law gave a new name for the squatters: informal settlers. Essentially, UDHA gives protection for big private ownership of land in the urban areas, ensuring that these are protected from illegal occupants. The law also widened the scope of private sector participation in the National Shelter Program (NSP).
