Gross domestic product, or GDP, is a measure of the total economic output of a country. It takes into account the value of all goods and services produced within a country's borders, regardless of the nationality of the producers. This includes everything from manufacturing and agriculture to services such as banking and healthcare. GDP is an important indicator of a country's economic health and is often used as a benchmark for comparing the performance of different economies. By understanding the concept of GDP, we can better analyze and interpret economic trends and make informed decisions about investments and policies.
