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.
Economic globalization
While within-country income inequality has increased throughout the globalization period, globally inequality has lessened as developing countries have experienced much more rapid growth. Economic inequality varies between societies, historical periods, economic structures or economic systems, ongoing or past wars, between genders, and between differences in individuals' abilities to create wealth. Among the various numerical indices for measuring economic inequality, the Gini coefficient is most often-cited.
