This report is organized as follows. The first chapter provides an overview of trends since 1970 in U.S. births and birth rates among U.S.-born women and foreign-born women. The following chapter zeroes in on the trend since 1984 in births outside of marriage, and what factors may be contributing to the growing gap in births outside marriage between U.S.-born and foreign-born women. The third chapter examines differences by mother's nativity and region of birth on a number of other demographic and economic characteristics, including age, race, education, employment, financial well-being, years in the U.S. and English language skills. The last chapter examines the economic and demographic profiles of new mothers who were born in one of the nine countries and one U.S. territory accounting for the largest share of new U.S. foreign-born mothers.
