Economic development means making your economy, or the economy of your country, larger and richer. Economic development is important for a country to become more successful, so it can provide a better quality of life for its citizens. In order to do this, a country can invest in things like schools, businesses, and factories, so they can make more money and provide more products and services. Additionally, countries can work to increase trade with other countries and make sure their citizens have access to more job opportunities.
