U.S. State Life Tables, 2022
Summary
Life expectancy in the U.S. varied by state in 2022, with Hawaii showing the highest and West Virginia the lowest. Most states saw an increase in life expectancy from 2021 to 2022.
Area of Science:
- Demography
- Public Health
- Biostatistics
Background:
- Life expectancy is a key indicator of population health and socioeconomic development.
- State-level variations in life expectancy highlight disparities in health outcomes across the United States.
Purpose of the Study:
- To present complete period life tables for each U.S. state and the District of Columbia (D.C.) for 2022.
- To analyze sex-specific life expectancy at birth and at age 65 across states.
Main Methods:
- Utilized 2022 final mortality statistics and U.S. Census Bureau population estimates.
- Incorporated Medicare data for individuals aged 66-99 for enhanced accuracy.
- Applied methodology consistent with national life table estimation, with state-specific modifications.
Main Results:
- Hawaii recorded the highest life expectancy at birth (80.0 years), while West Virginia had the lowest (72.2 years).
- Life expectancy increased in 48 states and D.C. between 2021 and 2022.
- Female life expectancy at birth exceeded male life expectancy in all states, with differences varying by state.
Conclusions:
- Significant state-level variation exists in U.S. life expectancy.
- The general increase in life expectancy suggests improving health trends in most states.
- Persistent sex-based disparities in life expectancy warrant further investigation.

491
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,...

322
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...

00:57Population Growth
27.8K
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.

01:20Actuarial Approach
284
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.

01:18Survival Curves
642
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.
