Age and parity influences on maternal mortality: United States, 1919-1969

L G Berry. Demography. 1977 Aug.

Abstract

Comparisons of crude and standardized rates of maternal mortality show that changes in age and parity distributions of births had some influence on maternal mortality trends for the years 1919-1969 in the United States. Changes in the age and parity distributions of births for cohorts of U.S. women also influenced crude cohort maternal mortality rates to some extent.
