Globalization
One index of globalization is the "KOF Index of Globalization", which measures three important dimensions of globalization: economic, social, and political. Another is the A.T. Kearney / Foreign Policy Magazine Globalization Index.
Measurements of economic globalization typically focus on variables such as trade, Foreign Direct Investment (FDI), Gross Domestic Product (GDP), portfolio investment, and income. However, newer indices attempt to measure globalization in more general terms, including variables related to political, social, cultural, and even environmental aspects of globalization.
History of globalization
Even as early as the Prehistoric period, the roots of modern globalization could be found. Territorial expansion by our ancestors to all five continents was a critical component in establishing globalization. The development of agriculture furthered globalization by converting the vast majority of the world's population into a settled lifestyle. However, globalization failed to accelerate due to lack of long distance interaction and technology. The contemporary process of globalization likely occurred around the middle of the 19th century as increased capital and labor mobility coupled with decreased transport costs led to a smaller world.
