Curious about health and habits?
Project Big Life offers a Canadian model with additional health and lifestyle inputs. Check its population and eligibility before using it; it is not a worldwide estimate.

02 · THE POPULATION PICTURE
If the death rates observed in Canada in 2022–2024 stayed the same at each age, these are the estimated proportions reaching each birthday.
A note for parents and younger readers: These figures apply mortality rates from the source period across all ages. They do not predict how medical care, living conditions or mortality rates may change over a child’s lifetime. Age 0 starts at birth.
This source does not publish survivor counts beyond your selected age. Average remaining years are available below; later milestones are not extrapolated.
Average remaining years
Average age reached
These are averages (means), not deadlines. The average is not necessarily the age that half the population reaches.
At older ages, estimates rely more on statistical modeling. Treat these rounded figures as broad population context.

For adults aged 18 and over. Answer any of these three questions for general guidance, or skip them all. Answers stay on this page and do not change the life-expectancy figures.
Choose one manageable step. These brief questions are not a health assessment or a score. Adapt suggestions to your abilities and circumstances; if a health condition limits activity or diet, follow your care team's guidance.
For children, use age-specific guidance with a parent or caregiver. WHO guidance for activity at different ages. Adult lifestyle questions are not shown for this age.
PUT THE NUMBERS IN CONTEXT
Room for possibility, not a countdown
Why is this different from life expectancy at birth?
Life expectancy at birth includes mortality risks across an entire lifetime. Once you reach a particular birthday, the calculation starts there. It asks about the years ahead among people who have already reached that age.
Remaining life expectancy is not life expectancy at birth minus your age.
What can these figures tell me?
They describe a hypothetical population exposed, at every future age, to the mortality rates estimated for the selected source period. This is called a period life table. It is a snapshot of mortality conditions, not a forecast of future improvements or setbacks.
People’s experiences vary. Your health, circumstances and habits do not change these estimates. These figures do not estimate your healthspan, independence or personal medical risk.
Methods, sources and version history
Each country uses its own published period life table. Sources, reference periods and population definitions differ, so this is not a country ranking. Canada and the UK use national statistical agency tables, the US uses the Social Security area population, and the five additional countries use UN demographic estimates. A country's figures are population context, not a prediction based on citizenship or where you move.
- Canada: Statistics Canada, 2022–2024. Table 13-10-0114-01; released January 13, 2026. Preliminary estimates, subject to revision.
- United States: Social Security Administration, 2023. Period table used in the 2026 Trustees Report. Covers the Social Security area population, including U.S. residents and certain territories and people abroad.
- United Kingdom: Office for National Statistics, 2022–2024. National life tables; released December 10, 2025.
- Australia, Costa Rica, Ireland, Mexico and New Zealand: United Nations, World Population Prospects 2024. Complete period life tables for 2023 (historical estimates), with published male, female and combined populations. These are UN estimates rather than the latest national statistical releases.
Sources retrieved September 24, 2026. Average remaining years come directly from each table's life expectancy column (eₓ). Conditional survival is the survivor count at the later age divided by the count at the starting age (lᵧ ÷ lₓ). All values in a calculation use the same country, period and category.
Input ages 0–100 represent exact birthdays. We do not add half a year. We show up to four later milestones. Below age 40, the sequence starts with 20-year steps; ages 40–64 use decade steps through 90, followed by 95, 100 and 105; ages 65 and over use 80, 85, 90, 95, 100 and 105. Only birthdays later than the starting age are shown: at most age 105 for Canada and the U.S., and age 100 for the U.K. and the five UN-based countries. No tail is extrapolated. Older-age estimates incorporate statistical modeling. Displayed probabilities are rounded from published counts.
The combined category is available for Canada and the five UN-based countries, using their published combined tables. We do not create a combined estimate for sources that do not publish one. No lifestyle adjustments, healthspan estimates or extra years are added. This tool has not received independent actuarial review.
Version 1.5 · September 24, 2026. Clearer child-age explanations, revised midlife milestones and expanded source and privacy notes. Version 1.4 introduced logo and sharing support; version 1.3 added eight-country coverage and optional adult guidance. The source data is unchanged in version 1.5. Shared links restore selections using the installed data; results may change after a future data update.

Does this account for longevity escape velocity?
No. Longevity escape velocity describes a proposed future acceleration in life extension. These period life tables do not model future medical breakthroughs or predict whether anyone will live long enough to benefit from LEV.
