The Census Bureau collects data on fertility of noninstitutionalized American women biannually in the Current Population Survey (CPS), and they have released the report for 2000 this week. This year's findings are particularly significant because they record a drop in labor force participation by mothers with infant children (especially white mothers over 30), the first significant decline since the Census began measuring participation (1976). From this page, users can access the eleven-page, .pdf-formatted report, a press release which gives highlights of the data, and detailed tables (e.g., Distribution of Women by Average Number of Children Ever Born, by Race, Age,and Marital Status). Data from the 1994, 1995, and 1998 CPS are also available at the site, as are historical time series tables, methodological tables, and links to related data on the Census site.
