1Centers for Disease Control and Prevention, National Center for Health Statistics, 6525 Belcrest Road, Hyattsville, Maryland 20782-2003, USA.
Summary
US life expectancy increased in 1998, reaching 76.7 years at birth. This gain was observed across all reported race and sex demographics, reflecting improved mortality trends.
Area of Science:
- Demography
- Public Health
- Biostatistics
Background:
- Current life tables provide vital statistics on mortality and population health.
- Understanding life expectancy trends is crucial for public health planning and resource allocation.
Purpose of the Study:
- To present the 1998 US current life tables.
- To analyze changes in life expectancy at birth by age, race, and sex from 1997 to 1998.
Main Methods:
- Utilized 1998 final mortality statistics.
- Incorporated July 1, 1998, population estimates.
- Integrated data from the Medicare program.
Main Results:
- Overall US life expectancy at birth was 76.7 years in 1998, a 0.2-year increase from 1997.
- Life expectancy increased for all four race-sex groups: black males (0.4 years), black females (0.1 years), white males (0.2 years), and white females (0.1 years).
Conclusions:
- US life expectancy showed a positive trend in 1998.
- Mortality improvements contributed to increased life expectancy across diverse demographic groups.

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.

01:22Life 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,...
01:18Survival 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.

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.

01:22Applications 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...
