Deaths: preliminary data for 2008.

Objectives-This report presents preliminary U.S. data on deaths, death rates, life expectancy, leading causes of death, and infant mortality for 2008 by selected characteristics such as age, sex, race, and Hispanic origin. Methods-Data in this report are based on death records comprising more than 99 percent of the demographic and medical files for all deaths in the United States in 2008. The records are weighted to independent control counts for 2008. For certain causes of death such as unintentional injuries, homicides, suicides, drug-induced deaths, and sudden infant death syndrome, preliminary and final data may differ because of the truncated nature of the preliminary file. Comparisons are made with 2007 final data. Results-The age-adjusted death rate decreased from 760.2 deaths per 100,000 population in 2007 to 758.7 deaths per 100,000 population in 2008. From 2007 to 2008, age-adjusted death rates decreased significantly for 6 of the 15 leading causes of death: Diseases of heart, Malignant neoplasms, Cerebrovascular diseases, Accidents (unintentional injuries), Diabetes mellitus, andAssault (homicide). From 2007 to 2008, age-adjusted death rates increased significantly for 6 of the 15 leading causes of death: Chronic lower respiratory diseases; Alzheimer's disease; Influenza and pneumonia; Nephritis, nephrotic syndrome and nephrosis; Intentional self-harm (suicide); and Essential hypertension and hypertensive renal disease.
