Deaths: final data for 1999.

OBJECTIVES: This report presents final 1999 data on U.S. deaths and death rates according to demographic and medical characteristics. Trends and patterns in general mortality, life expectancy, and infant and maternal mortality are also described. A previous report presented preliminary mortality data for 1999. METHODS: In 1999 a total of 2,391,399 deaths were reported in the United States. This report presents tabulations of information reported on the death certificates completed by funeral directors, attending physicians, medical examiners, and coroners. Original records are filed in the State registration offices. Statistical information is compiled into a national data base through the Vital Statistics Cooperative Program of the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention. For the first time in a final mortality data report, age-adjusted death rates are based upon the year 2000 population and causes of death are processed in accordance with the Tenth Revision of the International Classification of Diseases (ICD-10). RESULTS: The 1999 age-adjusted death rate for the United States was 881.9 deaths per 100,000 standard population, a 0.7 percent increase from the 1998 rate, and life expectancy at birth remained the same at 76.7 years. For all causes of death, age-specific death rates rose for those 45-54 years, 75-84 years, and 85 years and over and declined for a number of age groups including those 5-14 years, 55-64 years, and 65-74 years. Aortic aneurysm and dissection made its debut in the list of leading causes of death and atherosclerosis exited from the list. Heart disease and cancer continued to be the leading and second leading causes of death. The age-adjusted death rate for firearm injuries decreased for the sixth consecutive year, declining 6.2 percent between 1998 and 1999. The infant mortality rate, 7.1 infant deaths per 1,000 live births, was not statistically different from the rate in 1998. CONCLUSIONS: Generally, mortality continued long-term trends. Life expectancy in 1999 was unchanged from 1998 despite a slight increase in the age-adjusted death rate from the record low achieved in 1998. Although statistically unchanged from 1998, the trend in infant mortality has been of a steady but slowing decline. Some mortality measures for women and persons 85 years and over worsened between 1998 and 1999.

Deaths: preliminary data for 1999.

OBJECTIVES: This report presents preliminary data for 1999 on deaths in the United States. U.S. data on deaths are shown by age, sex, race, and Hispanic origin. Data on life expectancy, leading causes of death, and infant mortality are also presented. METHODS: Data in this report are based on a sample of deaths comprising more than 99 percent of the total deaths in the United States for 1999. The records are weighted to independent control counts of infant deaths, and deaths 1 year and over received in State vital statistics offices for 1999. Unless indicated, comparisons are made with final data for 1998. Effective with this report, all age-adjusted death rates for 1999 and earlier years are standardized to the year 2000 population. Also, effective with mortality data for 1999, causes of death are coded and classified according to the Tenth Revision of the International Classification of Diseases (ICD-10) replacing ICD-9 used in the United States for deaths occurring during 1979-98. RESULTS: In 1999 the age-adjusted death rate for the United States increased slightly, compared with 1998. For causes of death, declines in age-adjusted rates occurred for homicide (6 percent) and suicide (6 percent), while rates for Septicemia and hypertension increased 6.6 percent and 5.0 percent, respectively. Mortality also decreased for drug-induced deaths and deaths from injury by firearms. The infant mortality rate for the white population was down 3 percent, while the rate for the black population increased by 2 percent, but the increase was not statistically significant. Life expectancy remained the same at 76.7 years.

Deaths: final data for 1997.

OBJECTIVES: This report presents final 1997 data on U.S. deaths and death rates according to demographic and medical characteristics such as age, sex, race, Hispanic origin, marital status, educational attainment, injury at work, State of residence, and cause of death. Trends and patterns in general mortality, life expectancy, and infant and maternal mortality are also described. A previous report presented preliminary mortality data for 1997. METHODS: In 1997 a total of 2,314,245 deaths were reported in the United States. This report presents descriptive tabulations of information reported on the death certificates. Death certificates are completed by funeral directors, attending physicians, medical examiners, and coroners. Original records are filed in the State registration offices. Statistical information is compiled into a national data base through the Vital Statistics Cooperative Program of the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention. RESULTS: The 1997 age-adjusted death rate for the United States decreased to an all-time low of 479.1 deaths per 100,000 standard population, and life expectancy at birth increased to a record high of 76.5 years. The 15 leading causes of death remained the same as in 1996, although Human immunodeficiency virus (HIV) infection plummeted from the 8th leading cause of death to the 14th leading cause. Some of the 8th-14th leading causes of death shifted positions. HIV infection remained the leading cause of death for black persons aged 25-44 years. The largest decline in age-adjusted death rates among the leading causes of death was for HIV infection, which dropped 47.7 percent between 1996 and 1997. Mortality declined for all age groups, except for persons aged 85 and over. The infant mortality rate reached a record low of 7.2 infant deaths per 1,000 live births in 1997 although the decline in the rate from 1996 was not statistically significant. CONCLUSIONS: The overall improvements in general mortality and life expectancy in 1997 continue the long-term downward trend in U.S. mortality. The trend in U.S. infant mortality is of steady declines over the past four decades.

Deaths: final data for 1996.

OBJECTIVES: This report presents 1996 data on U.S. deaths and death rates according to demographic and medical characteristics such as age, sex, race, Hispanic origin, marital status, educational attainment, injury at work, State of residence, and cause of death. Trends and patterns in general mortality, life expectancy, and infant and maternal mortality are also described. METHODS: In 1996 a total of 2,314,690 deaths were reported in the United States. This report presents descriptive tabulations of information reported on the death certificates. Death certificates are completed by funeral directors, attending physicians, medical examiners, and coroners. Original records are filed in the state registration offices. Statistical information is compiled into a national data base through the Vital Statistics Cooperative Program of the National Center for Health Statistics, Centers for Disease Control and Prevention. Changes between 1995 and 1996 in death rates and differences in death rates across demographic groups in 1996 are tested for statistical significance. Unless otherwise specified reported differences are statistically significant. RESULTS: The 1996 age-adjusted death rate for the United States decreased, reaching an all-time low of 491.6 deaths per 100,000 standard population, and life expectancy at birth increased by 0.3 years to 76.1 years, a record high. The 15 leading causes of death remained the same as in 1995, although there were changes in the ranking of some causes. Replacing homicide, septicemia became the 12th leading cause of death, and Alzheimer's disease moved from the 14th to the 13th leading cause. For the third consecutive year, the number of homicide deaths dropped, making it the 14th leading cause of death. Mortality declined for all age groups, including persons aged 85 and over. The largest decline in age-adjusted death rates among the leading causes of death was for Human immunodeficiency virus infection, which dropped 28.8 percent in 1996, compared with the previous year. The infant mortality rate declined by 4 percent to a record low of 7.3 infant deaths per 1,000 live births in 1996. Neonatal and postneonatal mortality rates declined for all races combined as well as for postneonatal white infants. Although not statistically significant, mortality rates for white and black neonatal infants and black postneonatal infants also declined. CONCLUSIONS: The overall improvements in general mortality and life expectancy in 1996 continue the long-term downward trend in U.S. mortality. The drop in U.S. infant mortality continues the steady declines of the past four decades.

Why did black life expectancy decline from 1984 through 1989 in the United States?

OBJECTIVES: The objective of this study was to partition the change in US life expectancy into those major causes of death and age groups that contributed most to the decline in life expectancy for Black males and females and to the increase in life expectancy for White males and females in the period from 1984 through 1989. METHODS: By means of a life table partitioning technique, the positive and negative contributions of age and cause of death to changes in life expectancy were estimated. RESULTS: Causes contributing most to the decrease in life expectancy for Black males included human immunodeficiency virus (HIV) infection (< 5 and 20-69 years of age) and homicide (1-4 and 10-34 years of age); for Black females the causes included HIV infection (< 5 and 20-59 years of age) and cancer (65-79 and > or = 85 years of age). CONCLUSIONS: Mortality trends between the two major race groups in the United States diverged sharply, and without precedent, during the late 1980s. A description of these trends in terms of contributions to change in life expectancy may help us better analyze and interpret changes in the health of these groups and may contribute to a better allocation of resources for research, education, and public health programs.

Abortion surveillance, United States, 1988.

Since 1980, the number of legal abortions reported to CDC has remained fairly stable, varying each year by less than 3%. In 1988, 1,371,285 abortions were reported--a 1.3% increase from 1987. The abortion ratio for 1988 was 352 legally induced abortions/1,000 live births, and the abortion rate was 24/1,000 women ages 15-44 years. The abortion ratio was higher for black women and women of other minority races and for women less than 15 years of age. However, the abortion ratio for women less than 15 years was lower in 1988 than in any previous year since 1972. Women undergoing legally induced abortions tended 1) to be young, white, and unmarried, 2) to live in a metropolitan area, 3) to have had no previous live births, and 4) to be having the procedure for the first time. Approximately half of all abortions were performed before the eighth week of gestation, and greater than 85% were performed during the first trimester of pregnancy (less than 13 weeks of gestation). Black women and women of other minority races tended to obtain abortions later in pregnancy than did white women; however, age was a more dominant influence than race. Younger women tended to obtain abortions later than older women. Educational level strongly influenced when an abortion was performed; better educated women had an abortion earlier in gestation.
