Vital statistics are data on "vital events," namely births, deaths, and civil activities like marriages and divorces. Therefore, there are overlapping areas belonging both to the vital statistics and other topical sections of this guide.
For example, statistics on cancer mortality (the number of people who die of a certain disease compared with the total number of people) are available from the CDC's National Center for Chronic Disease Prevention and Health Promotion as well as from the National Vital Statistics Report.
