• Period life expectancy is the average number of years a person would live if they experienced the death rates of a given year at every age throughout their life. It's a summary of death rates in that year, not a forecast of how long people born then will actually live.
• These are UN estimates, which apply the same methods to every country, so they can differ slightly from the UK's own statistics.
