In 1967 few households had any method for faeces disposal. The typical house in all the villages except the small fresco village has one or two rooms with adobe walls, a dirt floor, and a tile or metal roof. After a major earthquake in 1976 a number of tile roofs were replaced with sheet metal, which can be considered comparable to tile in quality. In the small fresco village, which is located in a lower, warmer area, most houses have thatched roofs and walls made of reeds and mod. Most homes have a kitchen located in a separate room or area outside the house, and most families own the land on which their homes are constructed.
Dirt floors present a potential health risk, particularly for young children.
The means for the house factor scores increased in all the villages over the 20 years but were consistently lowest in the small fresco village. No houses were equipped with electricity in 1967. Families generally have few possessions. In the large fresco village two-thirds owned radios by 1987. Occupations Fathers' occupations are shown in table 4.
