How the Global Life Expectancy Board screensaver works
The saver reads real published life expectancy at birth figures from the World Health Organization's Global Health Observatory.
Countries are ranked by their real reported life expectancy in years.
The pipeline refreshes the data on the source's own real reporting schedule.
No key is required for the published WHO data.
What life expectancy at birth means
Life expectancy at birth is the average number of years a newborn could expect to live if they experienced the sex- and age-specific death rates prevailing in a given year and place. The World Health Organization derives it from life tables, preferring civil registration data with complete coverage and otherwise using household surveys and censuses, and publishes the estimates in its Global Health Observatory.
The figure is a period measure, a snapshot of mortality in a given year, and not a forecast for any person or generation. Because it averages across the whole life course, deaths in infancy and childhood pull it down sharply, so improvements in early-life survival often move it more than gains in old age. Differences within a country by income, region or sex can be large and are hidden behind the single number.
WHO notes that complete mortality data is lacking for many countries, so it fills gaps with modelling based on data from other populations. Its estimates may therefore differ from national statistics offices or other international agencies. Temporary shocks such as epidemics, conflict or heatwaves can dent a particular year, so compare series over time with caution.
A worked example
A country with a real reported life expectancy above 84 years appears near the top of the ranked board, exactly matching the WHO's own published figure.
Settings & tips
- Accent recolours the ranking bars.
- Figures are real WHO-reported national averages, not individual predictions.
- Life expectancy figures update on WHO's own real reporting cycle.
Frequently asked questions
- Is this real health data?
- Yes — real published figures from the WHO Global Health Observatory.
- Is a key needed?
- No. WHO publishes this data freely.
- Does this predict my lifespan?
- No — it shows real national averages only, not individual predictions.
- Is it free?
- Yes — free, no download, in your browser.
- Is life expectancy the age most people die?
- No. It is an average across all deaths, including infants, so many people live well beyond it when early deaths are rare.
- Why can figures differ between sources?
- Organisations use different data and statistical methods, particularly where national records are incomplete, so published values for the same country and year can vary slightly.
