began in the late 1970s, households took on an increased and more responsible economic role. The labor of family members is still the primary determinant of income. But rural economic growth and commercialization increasingly have rewarded managerial and technical skills and have made unskilled farm labor less desirable. As long as this economic trend continues in the countryside in the late 1980s, peasant families are likely to opt for fewer but better educated children. The consequence of the general changes in China's economy and the greater separation of families and economic enterprises has been a greater standardization of family forms since 1950. In 1987 most families approximated the middle peasant (a peasant owning some land) norm of the past. Such a family consisted of five or six people and was based on marriage between an adult son and an adult woman who moved into her husband's family. The variant family forms - either the very large and complex or those based on minor, nonstandard forms of marriage - were much less common. The state had outlawed concubinage, child betrothal, and the sale of infants or females, all of which were formerly practiced, though not common. Increased life expectancy meant that a greater proportion of infants survived to adulthood and that more adults lived into their sixties or seventies. More rural families were able to achieve the traditional goal of a three-generation family in the 1980s. There were fewer orphans and young or middle-aged widows or widowers. Far fewer men were forced to retain lifelong single status. Divorce, although possible, was rare, and families were stable, on-going units. A number of traditional attitudes toward the family have survived without being questioned. It is taken for granted that everyone should marry, and marriage remains part of the definition of normal adult status. Marriage is expected to be permanent. That marriage requires a woman to move into her husband's family and to become a daughter-in-law as well as a wife is still largely accepted. The norm of patrilineal descent and the assumption that it is sons who bear the primary responsibility for their aged parents remain. The party and government have devoted great effort to controlling the number of births and have attempted to limit the number of children per couple. But the authorities have not attempted to control population growth by suggesting that some people should not marry at all. In the
