A growing population can generate economic growth. The birth of more people equates to a greater number of parents investing in their youth. Increased purchases in products such as food, clothing, education-related expenses, sporting goods and toys feed the economy. Parents with small children purchase larger homes with more bedrooms and bathrooms to make room for their children. The larger homes that parents with children purchase feed the construction and home improvement industries economically. Children then grow into adults who work for pay and spend it in the economy.
