One of the primary criteria used to assess a country’s economy is the size of the nation’s Gross Domestic Product (GDP), which is the total value of all goods and services produced in one year.
Some sectors, such as agriculture, manufacturing, and oil, have been recognised for their significant contributions to a nation’s GDP over the years.
To effectively gauge the strength of a country’s key economic indicators, three main sectors—agriculture, industry, and services—are evaluated based on their percentage share of the total GDP. When combined, these percentages should amount to 100% of the GDP.
