Several recent trends in the vital statistics of the United States continued in 1996, including an increase in life expectancy and declines in infant mortality, births to teenage mothers, age-adjusted death rates, and death rates for children and adolescents.
In 1996, there were an estimated 3 914 953 births in the United States.
The preliminary birth rate remained unchanged at 14.8 births per 1000 population, and the fertility rate, births per 1000 women 15 to 44 years of age, was essentially the same at 65.7. Fertility rates rose slightly for most racial and ethnic groups except black women, for whom the rate hit a historic low of 70.8. Overall, fertility remains particularly high for Hispanic women, although there is considerable variation within this heterogenous group.
For the fifth consecutive year, birth rates dropped for teenagers.
Birth rates for women =30 years of age continued to increase.
The birth rate for unmarried women declined 1% in 1996 to 44.6 births per 1000 unmarried women, continuing the decline noted in 1995 for the first time in 2 decades.
The percentage of women who began prenatal care in the first trimester rose in 1996 to 81.8%, whereas the percentage with late (third trimester) or no care dropped to 4.1%. The rise in timely prenatal care was greatest for black and Hispanic women.
The percentage of low birth weight (LBW) infants reached 7.4% in 1996, its highest level since 1975.
The very low birth weight rate remained unchanged at 1.4%. (...)
