To find the average annual increase in global life expectancy, we can use the formula:
Average annual increase = (Final life expectancy - Initial life expectancy) / Number of years
Using the given values from 2000 to 2019:
Initial life expectancy = 66.8 years
Final life expectancy = 73.4 years
Number of years = 2019 - 2000 + 1 = 20
Average annual increase = (73.4 - 66.8) / 20
= 6.6 / 20
= 0.33 years per year
Therefore, the average annual increase in global life expectancy between 2000 and 2019 is approximately 0.33 years per year.
Solve this according the formula of life expectancy.
According to The Global Health Observatory, global life expectancy has increased by more than 6 years between 2000 and 2019 – from 66.8 years in 2000 to 73.4 years in 2019.
