The gross domestic product (GDP) is a metric for measuring a country’s economic output. Countries with higher GDPs create more products and services and, as a result, enjoy a higher quality of life. As a result, many individuals and political leaders regard GDP growth as a key indicator of national success, using the terms “economic growth” and “GDP growth” interchangeably. Many economists, however, believe that GDP should not be used as a proxy for overall economic performance, much less the success of society in general, due to several constraints.
