The distribution of anencephaly mortality rates was calculated by county for the continental United States. The average annual anencephaly mortality rate for all races and both sexes, based on 19681978 data for the population under 5 years of age, was 5.1 per 100,000 per year. The average annual anencephaly death risk for 19701975 was 25.4 per 100,000 live births per year. The distribution of anencephaly mortality was confirmed by comparing maps of mortality data and annual death risk for the period 19701975.
