The CIA World Factbook is, again, the root source for much of this data but, again, our link is to Wikipedia – where the data is easier to use.
There is a great debate about whether public (government) debt matters. Is it a good idea to 'borrow to invest'? How much? How should it be spent?
At Guides.Global we are pretty set in our opinion that too much borrowing is a bad thing: landing your children and grand-children with debt is immoral. You may, of course, disagree. Whatever your view, the level of public debt in the countries where you might live or do business is a factor to take into account.
