Trends and Variations in Reproduction and Intrinsic Rates: United States, 1990-2014.

Objective-This report presents trends in reproduction and intrinsic rates from 1990 through 2014. In addition, total fertility and gross reproduction rates by race and Hispanic-origin group are presented from 1990 through 2014, and net reproduction and intrinsic rates for selected race and Hispanic-origin group are presented from 2006 through 2014. Methods-Tabular and graphic data on the trends in the reproduction and intrinsic rates for the United States, by race and Hispanic origin of mother, are presented and described. Results-Rates of reproduction (total fertility, gross reproduction, and net reproduction), the intrinsic rate of natural increase, and the intrinsic birth rate were lower in 2014 than 1990. After a steady decline from 1990 through 1997, all rates increased from 1997 through 2007 but declined again from 2007 through 2013. The rates increased between 2013 and 2014. Among the race and Hispanic subgroups examined, the total fertility and gross reproduction rates were lower for all groups in 2014 compared with 1990. The net reproduction rate, intrinsic rate of natural increase, and intrinsic birth rate for the selected groups non-Hispanic white, non-Hispanic black, and Hispanic declined from 2006 through 2014.
