U.S. life expectancy by race and sex, 2024
1,515 final NCHS observations across five official population groups, three sex tables, and exact ages 0–100.
Data
Today’s generation estimates
Today’s values from the generation model behind the daily chart Life Days Left posted on X in 2026. The same code that draws that chart recalculates this table on every visit.

Representative birth-date values
| Generation | Birth-year band | Representative birth | Days left | Life left | Band range |
|---|---|---|---|---|---|
| Boomers | 1946–1964 | 4,224 | 14% | 2%–27% | |
| Gen X | 1965–1980 | 11,547 | 37% | 27%–47% | |
| Millennials | 1981–1996 | 18,048 | 56% | 47%–66% | |
| Gen Z | 1997–2012 | 24,495 | 75% | 66%–85% | |
| Alpha | 2013–present | 30,429 | 92% | 85%–100% |
“Band range” runs from the oldest boundary birth date to the youngest. Alpha’s youngest boundary is the as-of date. Negative values, when they occur, mean a modeled target has passed; they do not indicate a recorded death.

Definitions
What each field means
- Days left
- Modeled lifetime days minus exact calendar days lived for the representative birth date, rounded to a whole day.
- Life left
- Days left divided by modeled lifetime days for the same birth year, rounded to a whole percentage point.
- Band range
- Percentages calculated for the oldest and youngest boundary dates. It is not a confidence interval or a distribution of outcomes.
- As-of date
- The calendar date at the UTC−04:00 daily cutoff, matching the daily chart Life Days Left posted on X in 2026.
