Discussion
How does population growth influence the economic development of a country?
Population growth can influence economic development in both positive and negative ways. A growing population provides more workers, consumers and skilled people who can contribute to the development of agriculture, industries and services.
However, very rapid population growth can increase pressure on land, water, food, housing, education, healthcare and employment. If people are educated, skilled and provided with proper opportunities, a large population can become a valuable human resource and contribute to economic growth.
Therefore, population growth becomes beneficial when it is supported by education, skill development, employment opportunities and proper use of resources.
