Life expectancy (years)¹

Filled in from country, sex, and lifestyle. Edit it if you have a figure you prefer.

Life expectancy at birth, by country and sex: UN World Population Prospects 2024 (reference year 2023), taken from Wikipedia's compilation.
Projected end = date of birth + life-expectancy years. Conversions to smaller units use the Gregorian mean year of 365.2425 days (mean month = that ÷ 12). A birth-year average understates remaining years for people who have already survived to older ages.
Lifestyle adjustments are added to the country/sex figure; each factor's baseline option adds nothing, and factors are combined additively (an approximation — their real effects overlap). Activity, up to about ±3.5 years: Moore et al., PLoS Medicine 2012. Smoking, current smokers lose over 10 years vs never-smokers, former smokers recover most: Jha et al., NEJM 2013. Alcohol, vs ≤100 g/week, higher intake lowers life expectancy at 40 by roughly 0.5 to 4–5 years: Wood et al., Lancet 2018.
