The correct answer is: the number of years a person is likely to live.
Life expectancy refers to the average number of years that a person is expected to live based on various factors such as their country of residence, demographics, lifestyle choices, and medical advancements. It is usually calculated from birth and provides an estimate of how long a person can expect to live, on average, in a specific population.
To determine the life expectancy of a population, statisticians collect data on birth and death rates, and use mathematical models to estimate future trends. This information is then used by insurance companies, healthcare providers, and policymakers to make decisions and plan for the needs of different populations.
Factors that can influence life expectancy include access to healthcare, quality of healthcare, nutrition, lifestyle choices (such as smoking or exercise habits), genetics, and socioeconomic conditions.
It is important to note that life expectancy is a statistical measure and may not accurately predict the lifespan of an individual. Many external factors can impact an individual's lifespan, and while life expectancy gives us an idea of the average, it does not take into account variations among individuals within a population.
