An interesting variant to catch these would be where the over/under population is measured in percentage from the mean rather than absolute value from the mean.

Well, Singapore's population is about 5.399 mil. I don't think it would have mad the list regardless unless it was about percentage.

The states would probably have an overpopulation of maybe 1000, while these countries would have millions overpopulating theirs.

I think doing this purely by total population rather than population density is a bit silly. No one would consider China (at 146 people per sq. km) more overpopulated than Bangladesh (at 1237 people per sq. km). But according to this, China's more than 5 times as overpopulated. And where the heck is Mongolia? It seems like it should make this list very easily with a population of 2.9M and a land area of more than 1.5M sq. km.

If you want countries by population density, try this quiz and this one. About Mongolia, it appears to be missing. I didn't double-check the data on this quiz, but I will now.

Nope, the quiz is correct! Mongolia would be next on the list with -82 mil.

It's only silly, I think, if it claims to make a bigger point. Overpopulation and underpopulation both appear in scare quotes and the concept is pretty clearly laid out. I found it interesting.

I agree. My first answers were Monaco & Vatican City - then tried China, and the penny dropped!

I really enjoyed this quiz concept. Very cool. I suspect the Australians who drive around with aggressive anti-immigration bumper stickers about us being full would be surprised to discover we're underpopulated to the tune of 391 million people.

Don't use this quiz to argue for migration policies. The concept here does not take into account the climate of each country. For example, Australia is mostly desert so the actual "full-ness" is much lower than 400 million.

Over half of Australia's population lives within the three main urban centres, and most new immigrants gravitate to these centres...if population was spread more evenly across the habitable parts of the country, there would be no overcrowding issues in the cities. This is not a problem exclusive to Australia

Denmark should be allowed, or there should be a note saying "no overseas territories".

Presumably: [population of country]-[world population density]*[area of country]

It took a while to figure out why this was so counter-intuitive. But realizing it's about absolute numbers and not percentages is the key, I guess. So you can automatically exclude any small countries whether they are densely or sparsely populated. That explains why Monaco and Singapore don't show up. Still it's baffling how Mongolia could fail to make the list.

An odd quiz. It should be made clear in the description how these countries are chosen. I spent my time guessing countries with a high population density.

Easiest strategy I can devise: for "overpopulated" just guess countries that are very populous. For "underpopulated" just guess countries that are huge.

You've misread the description. It's saying that if the entire world had the same population density, then you'd expect Russia (due to its immense size) to have 777 million more people than it currently does.

Please add a note that overseas territories aren't included, since obviously Denmark would be on the list if Greenland were included.

"Underpopulation" doesnt exist considering it doesnt have a negative effect on anything other than gov't entities and corporations.

I'm a bit interested on how you got the set density for the world.. It doesn't seem to be world population / land mass. It's not the median density of the countries and it's not the average. Can you enlighten me on how you got the number for your density?

It's world population / land mass (minus Antarctica). Since featured it's taken over by the Quizmaster and I haven't edited it since.

Shouldn't Denmark be added? Greenland is part of it and is extremely huge. But it only has about 50,000 people. It is very underpopulated, also because it is a whole 2,166,000 square kilometers big.
