1U.S. Department of Health & Human Services, Centers for Disease Contorl and Prevention, National Center for Health Statistics, Division of Vital Statistics, Hyattsville, MD 20782, USA.
Summary
In 2006, U.S. life expectancy at birth reached 77.7 years, a 0.3-year increase from 2005. This rise in life expectancy was observed across all demographic groups, including males, females, and racial populations.
Area of Science:
- Demography
- Public Health
- Biostatistics
Background:
- Life tables are essential tools for understanding mortality patterns and population health.
- Previous life table methodologies have been revised to enhance accuracy and comparability.
Purpose of the Study:
- To present complete period life tables for the United States for the year 2006.
- To analyze age-specific death rates and their impact on life expectancy.
- To provide detailed life expectancy data by age, race, and sex.
Main Methods:
- Utilized 2006 final mortality statistics and population estimates.
- Incorporated 2006 Medicare data for individuals aged 66-100.
- Applied a revised methodology for life table estimation, consistent with the 2005 U.S. Life Tables report.
Main Results:
- Overall life expectancy at birth in 2006 was 77.7 years, an increase of 0.3 years from 2005.
- Life expectancy at birth increased for males (75.1 years) and females (80.2 years).
- Increases in life expectancy were observed across racial groups, including white and black populations, and for both sexes within these groups.
Conclusions:
- Life expectancy in the United States continued to improve in 2006.
- The revised methodology provides more accurate and comparable life table data.
- Mortality trends indicate positive public health developments across diverse demographic segments.

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
01:22Applications of Life Tables
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...
01:20Actuarial Approach
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

01:29Life Histories
Constrained by limited energy and resources, organisms must compromise between offspring quantity and parental investment. This trade-off is represented by two primary reproductive strategies; K-strategists produce few offspring but provide substantial parental support, whereas r-strategists produce much progeny that receives little care. These strategies are related to an organism’s survival likelihood across its lifespan, which is represented by a survivorship curve. Three general types of...
01:18Introduction To Survival Analysis
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.

01:18Survival Curves
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
