This map shows government debt as a percentage of gross domestic product (GDP) comparing time 
periods of 1932 and 2009. This map suggests that overall, the general trend is going towards 
higher debt, especially in western countries. Where debt was not present in 1932 for some 
countries, it has become a part of their economy.
