2020 life expectancy estimates for the total, male, and female populations across all 50 U.S. states and the District of Columbia. The data originates from the National Center for Health Statistics via data.cdc.gov and was last updated in April 2025. It provides state-level metrics derived from complete period life tables.
Use Cases
- Analyze geographic disparities in life expectancy by ranking states using the LE and Quartile columns.
- Compare gender-based mortality gaps within and between states using the Sex and LE columns.
- Assess the statistical reliability of life expectancy estimates by examining the SE (standard error) column for each state-sex group.
- Map life expectancy trends across the United States by joining the State column with geospatial boundary data.
Strengths
- Covers all 50 U.S. states and the District of Columbia.
- Provides disaggregated data for total, male, and female populations (Sex column).
- Includes a measure of estimate uncertainty via the SE (standard error) column.
Limitations
- Limited to a single year (2020), preventing longitudinal trend analysis.
- Lacks individual-level data or demographic covariates beyond state and sex.
- Sample size and row count are unknown, limiting assessment of granularity.
