Gross domestic product (GDP) is the market cost of goods and services produced within a certain period, regardless of the national origin of applied factors of production. Income of U.S. citizens and corporations received from abroad are not taken into account for index calculation.
GDP is a key indicator of the country's economic activity. Its main components are consumer spending, investment, net exports of goods and services, and government spendings.
GDP growth is accompanied by the rise of the economy and the dollar tends to strengthen.
