The national debt pizza: How much is your slice?

You might find this hard to swallow


The people at HowMuch.net call it the Snowball of Debt, but honestly, it looks more like a pizza. Or a vast, boiling vat of paella.

The ingredients are country-shaped. The biggest countries are near the centre, the smallest ones at the edge. Their size does not reflect the relative differences in actual, geographical area – check your atlas: Ireland is not bigger than Germany, and the U.S. is not smaller than Singapore.

The clue is in the dollar amount under each country name: that is how much each citizen owes as a share of their nation's debt. The bigger that figure, the bigger the country on this pizza. This is what the top ten looks like:

  • Japan: $85,695
  • Ireland: $67,148
  • Singapore: $56,113
  • Belgium: $44,203
  • United States: $42,504
  • Canada: $42,143
  • Italy: $40,461
  • Iceland: $39,732
  • Austria: $38,700
  • United Kingdom: $36,206
  • These are all well-developed, high-income nations. Apparently, you need to be rich to be deep in debt. The reverse applies to the other side of the spectrum. The citizens of some of the world's poorest countries are also the least burdened by national debt. Here is that other top ten:

  • Liberia: $27
  • Tajikistan: $51
  • Democratic Republic of Congo: $91
  • Burundi: $98
  • Kiribati: $127
  • Malawi: $172
  • Uzbekistan: $177
  • Uganda: $194
  • Haiti: $204
  • Mali: $208
  • But the reverse relationship between a nations level of development and its debt is not linear. Some relatively well-developed economies have very low per-person debt levels. Chile, the Czech Republic and Slovakia, for example, bunched together near the right-hand edge of the pizza. The tasty colour-coding provides more evidence of that non-linearity. The colours express the public debt as a share of GDP:

  • green means less than 30% (well done New Zealand, China and Botswana – among many others);
  • yellow is for anywhere between 30% and 60% (not too shabby, India, Montenegro and Australia, etc.);
  • orange indicates debt levels between 60% and 100% (come on Germany, Uruguay and Mongolia – you can do better);
  • if your country is in the red, it is one of the Deep Debt Dozen, the countries who owe more than the value they produce in an entire year.
  • Actually, its a few more than twelve, but why waste a nice alliteration? They include most but not all of the countries with the highest debt per person, and some others much further down that list: Japan, Ireland, Singapore, Belgium, Italy, Greece, Barbados, Cyprus, Jamaica, Portugal, Lebanon, Grenada, Cape Verde and Eritrea.

    Space toilets: How astronauts boldly go where few have gone before

    A NASA astronomer explains how astronauts dispose of their, uh, dark matter.

    Videos
    • When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
    • Yes, there have been floaters in space. The early days of space exploration were a learning curve!
    • Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.

    • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
    • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
    • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
