Gross domestic product (GDP) is a measure of the extent of the economic activity within the country. The strict definition of GDP is the sum of market values or prices of all final products and services, as a result of the economy over a certain period of time. When the GDP is high, it means that the country increases production in the economy, citizens have higher incomes and spend more. Small businesses account for approximately 60% of the gross domestic product (GDP) in the United States.
