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.
Global citizenship
Global pollsters and psychologists have studied individual differences in the sense of global citizenship. Beginning in 2005, the World Values Survey, administered across almost 100 countries, included the statement, “I see myself as a world citizen.” For smaller studies, several multi-item scales have been developed, including Sam McFarland and colleagues’ Identification with All Humanity scale (e.g., “How much do you identify with (that is, feel a part of, feel love toward, have concern for) . . . all humans everywhere?”), Anna Malsch and Alan Omoto’s Psychological Sense of Global Community (e.g., “I feel a sense of connection to people all over the world, even if I don’t know them personally”), Gerhard Reese and colleagues’ Global Social Identity scale (e.g. “I feel strongly connected to the world community as a whole.”), and Stephen Reysen and Katzarska-Miller's global citizenship identification scale (e.g., “I strongly identify with global citizens.”). These measures are strongly related to one another, but they are not fully identical.
