United States Life Tables, 2021
Summary
Life expectancy in the U.S. declined in 2021, with significant drops observed for American Indian/Alaska Native populations. Overall life expectancy at birth fell to 76.4 years.
Area of Science:
- Demography
- Public Health
- Biostatistics
Background:
- Life expectancy is a key indicator of population health and socioeconomic status.
- Recent trends suggest potential declines in life expectancy due to various factors.
Purpose of the Study:
- To present complete period life tables for the United States for 2021.
- To analyze life expectancy trends by Hispanic origin, race, and sex.
Main Methods:
- Utilized 2021 final mortality statistics and U.S. Census Bureau population estimates.
- Incorporated Medicare data for individuals aged 66-99.
- Applied established methodologies for estimating life tables across different demographic groups.
Main Results:
- Overall life expectancy at birth decreased to 76.4 years in 2021, a 0.6-year decline from 2020.
- Life expectancy fell for both males (73.5 years) and females (79.3 years).
- The American Indian and Alaska Native non-Hispanic population experienced the largest decrease (1.5 years).
Conclusions:
- The U.S. experienced a decline in life expectancy in 2021, reversing previous gains.
- Disparities in life expectancy persist across racial and ethnic groups.
- Further research is needed to understand the contributing factors to these trends.

105
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
72
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
79
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.

166
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.

01:18Introduction To Survival Analysis
247
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.
