As in previous reports,1 the data for this article are drawn principally from two sources, the Monthly Vital Statistics Report, published by the National Center for Health Statistics2,3 and the Demographic Yearbook, published by the Statistical Office of the United Nations.4 In both instances, those responsible for the publication were kind enough to make the material available before the actual publication date, thus making it possible for this article to published in this December issue of Pediatrics. The limitations on the data used are explained in these reports and do not differ from previous years. All the data for 1970 are provisional and are based upon 10% sample of materials received in state offices between two dates 1 month apart, regardless of when the event occurred.
