Description:The statistics in this report have been assembled by the National Center for Health Statistics, Public Health Service, to answer questions frequently asked about vital and health statistics for the United States. Information on births, deaths, marriages, divorces, and life expectancy is based on vital data gathered by the Center's Division of Vital Statistics. Estimates for selected health conditions, chronic conditions, persons injured, and days of bed disability came from the Division of Health Interview Statistics. Health personnel data were obtained from the Division of Health Resources Statistics. Reported cases of communicable diseases came from the Center for Disease Control, Atlanta, Georgia. Vital statistics shown in this report include only events occurring within a specified area. Beginning with 1933, all data cover events occurring within the entire conterminous (48) United States. Beginning with 1959, the figures include Alaska, and starting with 1960, they include Hawaii. For the years prior to 1933, data for marriages, divorces, and births, when these are shown as having been adjusted for underregistration, are for the entire United States. Data for registered births and deaths, prior to 1933, are for expanding groups of registration States. Fetal deaths are excluded from birth and death statistics. Fetal death figures include only fetal deaths for which the period of gestation was given as 20 weeks or more or was not stated. Numbers shown as estimated in certain tables are based on a sample of incomplete data. Numbers shown as provisional are based on figures reported on a monthly basis and are subject to revision in final tabulations, Rates are based on population figures from the Bureau of the Census. Birth and divorce rates for 1941-46 are based on population including the Armed Forces abroad; other rates are based on total population residing in the area. For years ending in a zero, rates are based on the enumerated population as indicated in table 1. For all other years, rates are based on estimated midyear population.
