Detailed Solution:
The correct answer is “Working population of 15 to 59 years”.
The demographic dividend is the working population of 15 to 59 years.
This demographic group is considered to be the most productive age group and can contribute significantly to a country's economic growth if they are provided with education, skills, and employment opportunities.
Working population of above 60 years: This group is typically not considered part of the demographic dividend, as they are generally retired or out of the workforce.
Working population of 14 to 50 years: This range is too narrow and does not capture the full scope of the working-age population.
0-6 years population: This group is considered a dependent population, as they are not yet of working age.
Working population of 15 to 59 years: This is the correct definition of the demographic dividend, as it includes individuals who are actively participating in the labor force.
