The continuous decline in fertility in the United States since 1957, while affecting all elements of the population, has been most pronounced and most rapid among those groups which previously had the highest fertility - blacks, American Indians and Mexican Americans-all of whom experienced fertility declines more rapid than those experienced by urban whites between 1957-1960 and 1967-1970. Among urban whites, fertility decline has been heavily concentrated among those of low income. The decline was especiallyrapid for third and higher order births, suggesting a heavy concentration of completed fertility at two-child families. The rapid decline, and the narrowing of the traditionalfertility differentials among various subgroups have important implications in the areasof poverty, education, the role of women in society and the dynamics of local area growth.
