This paper uses new methods to determine the sources of the sharp fall and then the steep rise in personal income inequality between 1959 and 1989. The increase in the proportion of single-head families tended to boost inequality over the entire period. Forty percent of the reduction in income inequality in the 1960s occurred because of the decline in earnings inequality among male heads of families; more than one-third of the increase in inequality after 1969 occurred because inequality in male earnings soared. Since 1979 females' gains in earnings have increased inequality because these gains have been concentrated increasingly in families with high incomes.
本文采用新方法来确定1959年至1989年间个人收入不平等现象先急剧下降然后又大幅上升的根源。单亲家庭比例的增加在整个时期都倾向于加剧不平等。20世纪60年代收入不平等现象减少的40%是由于家庭男性户主之间收入不平等的下降；1969年之后不平等现象增加的三分之一以上是由于男性收入不平等大幅飙升。自1979年以来，女性在收入方面的增加加剧了不平等，因为这些增加越来越集中在高收入家庭。
