Ranking countries by their government debt to GDP

The United States is hardly the only rich country struggling with high government debts. Here's a ranking of wealthy countries by central government debt as a percentage of gross domestic product. GDP is the broadest measure of economic activity.

These are figures provided by the World Bank from 2010, the most recent year for which data is available. The percentages have likely increased since then for most countries. But the rankings likely haven't changed much.
