| Generation | Birth-year band | Representative birth | Days left | Life left | Band range |
|---|---|---|---|---|---|
| Boomers | 1946–1964 | 4,269 | 14% | 2%–27% | |
| Gen X | 1965–1980 | 11,592 | 37% | 27%–47% | |
| Millennials | 1981–1996 | 18,093 | 56% | 48%–67% | |
| Gen Z | 1997–2012 | 24,540 | 75% | 67%–85% | |
| Alpha | 2013–present | 30,474 | 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 @lifedaysleft chart ↗.
