Detailed Solution

The above statement is true.
Life expectancy means how many years an individual is expected to live at the time of birth.
The definition of life expectancy is an estimate of the typical number of extra years that a person of a particular age might expect to live. The most often used measure of life expectancy is life expectancy at birth. However, it is speculative to measure life expectancy. It is anticipated that for the remainder of their lives, those born in the year in question would be subject to the age-specific death rates for that year. The prediction, in essence, foretells age-specific mortality (death) rates for a certain period across the whole lifespan of the population born (or alive) during that period. In addition, local circumstances have an impact on life expectancy. For example, less developed countries have a shorter life expectancy at birth compared to highly developed nations.
