United States Life Tables, 2017.
Summary
US life expectancy declined slightly in 2017. Overall life expectancy at birth decreased to 78.6 years, with declines observed for males and white populations.
Area of Science:
- Demography
- Public Health
- Biostatistics
Background:
- Complete period life tables are essential for understanding population health trends.
- Mortality statistics and population estimates are key inputs for life table calculations.
- Previous methodologies for Hispanic and other population groups have been refined.
Purpose of the Study:
- To present comprehensive period life tables for the United States for 2017.
- To analyze life expectancy trends by race, Hispanic origin, and sex.
- To provide updated demographic data for public health research and policy.
Main Methods:
- Utilized final mortality statistics from 2017.
- Incorporated July 1, 2017 population estimates based on the 2010 decennial census.
- Included 2017 Medicare data for individuals aged 66-99.
Main Results:
- Overall life expectancy at birth in 2017 was 78.6 years, a decrease from 78.7 in 2016.
- Life expectancy decreased by 0.1 year for males and remained unchanged for females.
- Declines were observed for the white and non-Hispanic white populations, while other groups saw no change.
Conclusions:
- US life expectancy experienced a slight decline in 2017, reversing previous trends.
- Sex and race disparities in life expectancy persist.
- Continued monitoring of mortality trends is crucial for public health interventions.

412
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
256
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
236
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.

01:18Introduction To Survival Analysis
639
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.

00:57Population Growth
27.6K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
