Economic Growth is an increase in the production of economic goods and services, compared from one period of time to another. The most common measure of economic growth is the percentage change in real gross domestic product (GDP). Economic growth can be caused by changes in technology, population size, or resources available to produce goods and services.The benefits of economic growth are many.For example, when GDP grows faster than the population does, per capita income rises. This means that people have more money to spend on things they enjoy.Economic growth also allows businesses to expand and create new jobs. And finally, it leads to improvements in living standards as people have more money available to buy things like food, clothing, and housing.
