There are no children in the Vatican, so of course the median age will be very high. But it is a fluke, so it would be ridiculous to include the Vatican.
The "great leap forward." During the 1950s under Communist rule forced agricultural reforms and willful ignorance to accept that the failings of Communist policy led to massive starvation and somewhere between 20 and 50 million deaths in the country. The birth rate plummeted, the death rate skyrocketed, but after things stabilized and recovered somewhat there was a huge baby boom starting in the early 60s. As a result, the large bulk of China's population was born after 1962 and the median age is not very high. In about 20 or 30 years China will likely have one of the highest median ages in the world, though.
Jorissie: not so much since they implemented the one child policy in 1979. I'm sure this is what Tempest is referring to.
Their median age is currently 37-38, on par with the US but their fertility rate is low, especially in the Northeast, therefore it might make the list soon.
Taiwan, on the other hand, is not far off this list, their median age being at 41-42
Funny quiz. Actually, the European continent has not aged THAT much. A number of post-communist countries in the east have a high median age because young people have emigrated in the search of better jobs in the west. In the west they are not (yet) counted as part of the population because they don't have citizenship.
So the secret to living to an old age is to either eat lots of Mediterranean food or drink a lot of alcohol. Oh, and not have wars or immigrants. That's also important.
High life expectancy, fertility rate below the country's replacement level, net emigration, or high immigration of old people, poor economic opportunities, being rich for a long period of time (i.e. enough for low fertility rates to have lasted a couple generations). The European countries here tend to be Eastern Europe which have low fertility rates, relatively poor economic opportunities compared to other EU countries, Japan has, much like South Korea, China, Taiwan, Singapore etc. very low fertility rates, however is probably the only non-European country not to make the list as the other countries haven't been rich long enough for the fertility rate to make a big enough impact. I'm sure soon there will be many more Asian countries on this list. I'm sure cultural pressures in these countries are making fertility rates so much lower than in Europe as well.
I think China's population at some point is expected to plateau while India's population will continue to grow and pass China as the world's most populated country
Monaco, being a tax haven, is also the playground of the mega-rich, who tend to be older, so it attracts plenty of very rich people who settle there. I suspect that might be a factor with Liechtenstein as well.
Croatia, Bulgaria, Serbia all surprised me, I didn't get them until the very end. I didn't expect them to have a very high age (Especially former Yugoslav countries). Slovenia was expected but Serbia & Croatia surprised me!
It's partly to do with low fertility rates and partly with high emigration of younger people due to low economic opportunities but good educational systems.
The secret is to have enough food, good access to medical care, hospitalisation, aged care, minimal opportunity for parasites and diseases to flourish, e.g. malaria, cholera, aids, ebola etc etc. temperate climate, smaller families, no religious fanatics or factions, comfortable living quarters, enough clothes, and good hygiene including toilet habits, bathing and food preparation being most important, honest police, army and government to minimise corruption and a free press......... that's all.
I’m surprised South Korea, Australia, and the Scandinavian countries weren’t on there. But I did notice if a country was there, the closest neighbor was often there as well, such as Spain and Portugal.
Birth rates are lower in developed countries with higher inequality between the sexes because women have to work outside the home in addition to doing all the housework and childcare (hence South Korea now being on the list).
The Scandinavian countries are generally more equal and encourage fathers to be involved with generous parental leave for both parents. Other social programs make it easier for people to afford to have kids. Their birth rates aren't that much higher than some of the countries on this list, but combined with high life expectancy, it's enough to keep them off it.
It may be nit-picking, but I wish they would call the quiz Countries with HIGHEST median age. It makes no sense to say "oldest age" just like it makes no sense to say "cheap price".

Edit: I see that other countries have changed as well
yet people support abortions
