Frequently Asked Questions
What is a life expectancy estimator?
It is a tool that estimates an average lifespan from population statistics, your country, gender and lifestyle factors. The result is a group-level average, not a personal guarantee.
How accurate is a life expectancy estimate?
It is accurate as a population average, and it cannot predict the outcome for any one person. Individual lifespans vary widely around the average.
What data does the estimate use?
The estimate starts from United Nations population data for country and gender baselines, then applies adjustments for lifestyle factors such as smoking and exercise.
Why do women live longer than men on average?
Women outlive men on average for a mix of biological and behavioral reasons, including hormonal protection before menopause, lower rates of smoking and heavy drinking, and lower rates of fatal accidents.
