If population growth is rapid but skill training is weak, why can the benefit of a young population decline?

Correct answer: क्योंकि कौशल की कमी रोजगार-क्षमता घटा सकती है

Direct answer: B is correct. A young population can become a demographic dividend only when many young people are healthy, educated, trained and able to find productive work. Rapid population growth increases the number of young people, but numbers alone do not create jobs or income. If schooling is poor and vocational, technical or professional training is insufficient, young people may not possess the skills employers need. This can lead to unemployment, underemployment and dependence, so the possible economic benefit becomes smaller. A is wrong because youth do not automatically create employment merely by being young. B is correct because employability depends partly on relevant knowledge and skills. C is wrong because a high birth rate adds population but does not teach skills. D is wrong because migration may continue and is not the main reason for the reduced benefit. Memory cue: demographic dividend needs both a young workforce and investment in education, health and skills.
