Age-adjusted death rates in the United States dropped significantly between 2005 and 2006 and life expectancy hit another record high, according to preliminary death statistics released today by CDC's National Center for Health Statistics.
The 2006 age-adjusted death rate fell to 776.4 deaths per 100,000 population from 799 deaths per 100,000 in 2005, the CDC report said. In addition, death rates for eight of the 10 leading causes of death in the United States all dropped significantly in 2006, it said. These included a very sharp drop in mortality from influenza and pneumonia.
The preliminary infant mortality rate for 2006 was 6.7 infant deaths per 1,000 live births, a 2.3 percent decline from the 2005 rate of 6.9.
