The traditional American family consisting of a husband, wife and children is becoming less and less frequent. More people who are illegally married are living together. More and more children are being raised in single-parent families, by both poor women and by women who are professionally employed. Others postpone marriage and childbirth and as a consequence bear fewer children than women who marry earlier. Among the educated more and more couples are deciding to have fewer and fewer children. An exception to this trend occurs among blacks, Hispanics and among the very poor. In 1990 the size of the average American family was 3.2 individuals.
