The negative correlation between female employment and fertility in industrialized nations has weakened since the 1960s, particularly in the United States. We suggest that the continuing influx of low-skilled immigrants has led to a substantial reduction in the trade-off between work and childrearing facing American women. The evidence we present indicates that low-skilled immigration has driven down wages in the US child-care sector. More affordable child-care has, in turn, increased the fertility of college graduate native females. Although childbearing is generally associated with temporary exit from the labor force, immigrant-led declines in the price of child-care has reduced the extent of role incompatibility between fertility and work.
