When Standard & Poor's downgraded the US from its AAA status to AA+ on Aug. 5, it knocked just one country off a lengthy list. Now, there are 18 nations with AAA credit ratings. Calculations of GDP and government gross debt are from the International Monetary Fund (IMF) for 2010. The US had a GDP of about $14.6 trillion in 2010, the IMF estimates. Its debt, of about $13 trillion, is roughly 92 percent of its GDP. Data were not available for the small, AAA-rated sovereignties of Lichtenstein, Guernsey, and the Isle of Man.
And missing from the list? Some of the US's top economic competitors.
