The data, from IMF, does not include China or India.
The chart shows data for net debt (gross debt reduced by certain assets: gold, currency deposits, debt securities etc.).
Viewing our post on the data in 2014 we can see that the USA improved on the expectations, managing to hold net debt to 80% instead of increasing to 88% as expected. Nearly every country managed to take on less debt than predicted (Vietnam took on more, but is very low so this is not a problem).
Taking on debt to invest in valuable resources (building roads, mass transit, internet infrastructure, education, environmental regulation and enforcement, health care, renewable energy…) that will boost long term economic performance can be very useful. The tricky part is knowing the debt levels doesn’t tell you whether the debt was taken on for investment or just to let current taxpayers send the bills for their consumption to their grandchildren.
Also government debt can become a huge burden on the economy (especially if the debt is owed outside the country). The general consensus today seems to be that 100% net debt level is the maximum safe amount and increasing beyond that gets riskier and riskier.
