Annual Summary of Vital Statistics—1987

[摘要] Data for this article, as in previous reports,1 are drawn principally from Monthly Vital Statistics Report, published by the National Center for Health Statistics (NCHS). 2-6 The international data come from the annual Demographic Yearbook7 and the quarterly Population and Vital Statistics Report,8 both published by the Statistical Office of the United Nations, which has also been kind enough to provide directly more recent data reported by various countries. US data for 1987 are estimates by place of occurrence, based upon a count of all certificates received in state offices between two dates, one month apart, regardless of when the event occurred.
