Using data from Eurostat, we identified the top 10 European countries with the highest government debt as a percentage of GDP. The chart above shows that as of the third quarter of 2012, the latest period for which quarterly data is available, Greece, Italy, and Portugal had the highest government debt ratio. Ireland was close behind Portugal, with a ratio that has been increasing at the fastest rate out of all the countries in the list. Cyprus, which has been in the news lately due to problems in its banking sector, had a debt ratio not much higher than Germany.
