Mortality

• Age-adjusted Death Rates: Age-adjusted death rates are weighted averages of age-specific death rates. The weights are the proportion of persons in corresponding age groups based on a standard million population. In this report the standard million U.S. population for the year 2000 is used. The advantage of age-adjusted rates for total deaths compared with unadjusted rates is that they allow for comparisons across jurisdictional, ethnic, and race/sex groups.
• Early Infant Deaths: Early Infant Deaths is the term utilized in this report to refer to infant deaths under one day of age. Hebdomadal Deaths are deaths under seven days of age, Neonatal Deaths are deaths under 28 days of age, and Postneonatal Deaths are deaths 28 days and over but under one year of age.
• Perinatal Deaths: Defined as the sum of natural fetal deaths of 28 or more weeks gestation and the deaths of infants under seven days of age. The concept focuses on the critical thirteen-week period at the end of a normal 40-week gestation as well as the first week of life of the newborn. It is used as a result of differing definitions of infant deaths in the world.
• Residence Data: These refer to the Virginia city or county where the mother resided for a birth, where the patient resided for an induced termination of pregnancy or a spontaneous fetal death.  The term includes the vital events of Virginia residents regardless of where the event occurred
• Total Deaths: Total Deaths include Infant Deaths and Maternal Deaths. Induced Terminations and Natural Fetal Deaths are excluded.
• Total Infant Deaths: These are deaths of children under one year of age, some of whom may have been born in the previous year.
• Underlying Cause of Death: This is the term by which deaths are classified and listed in the tables, to be distinguished from the immediate and other causes of death listed on the death certificate. It may be defined as (a) the disease or injury which initiated the train of morbid events leading directly to death, or (b) the circumstances of the accident or violence which produced the fatal injury.
