Talk:List of countries by median age

Interesting correlation
I noticed one peculiarly interesting thing hidden in these statistics. The three large countries at the top (i.e. Japan, Germany and Italy) are all precisely the Axis powers that lost in the Second World War. That seemingly has something to do with the fact that these societies and peoples, at some point, simply stopped procreating as many children as the rest of the world. By the way, it's been 65 years since the war and there median ages are all near 50. Food for research for some budding mass psychology student, I guess ... 202.3.77.210 (talk) 04:29, 30 June 2011 (UTC)

Started to update from 2010 estimates to 2014 estimates using the CIA Factbook in the references. Will continue as time allows. Some are out of order now. Alphabetical would have been more convenient because that can't change. Jersey got much younger for some reason while most other countries are aging. Since I haven't changed the default order you can see which ones moved up or down in the order. — Preceding unsigned comment added by 175.177.194.177 (talk) 15:38, 19 May 2015 (UTC)

Median vs. Average
The table column heading uses the word "Average". If these are truly medians, then this heading should be changed to reflect that. I tried to look at the CIA factbook website but I'm not sure where to find the median age numbers, so I can't verify that these are medians. — Preceding unsigned comment added by Mrfout (talk • contribs) 15:15, 26 September 2019 (UTC)

Ranks
I presume that countries are intended to be ranked by median age. They're not - there's an appreciable number of discrepancies between the ordering by rank and the ordering by median age. Lavateraguy (talk) 07:52, 17 April 2020 (UTC)
 * Thanks for the heads-up. I fixed it.  Useight (talk) 06:03, 22 April 2020 (UTC)

Map
Is someone able to make an updated version of this map, used in this article and various others? It is of course significantly outdated at this point, but more importantly, it has at least one glaring error - Hungary's median age is 43.6, while the map puts it in the 14-20 range... which obviously must have been wrong even in 2016.

 * Pinging original uploader in case they're still active. Lennart97 (talk) 13:07, 18 October 2021 (UTC)
 * Yeah, that's definitely incorrect. I'll look into this at some point to see if I can update it. theZcuber (talk) 20:50, 18 October 2021 (UTC)
 * Eh, just looking into this. I probably don't have the time to manually review the 190+ countries to determine what changed. Hungary is probably the only thing that needs to be updated, as the rest I'd imagine hasn't changed too much. theZcuber (talk) 05:30, 19 October 2021 (UTC)
 * That's fine with me! Then the map will at least be accurate for 2016 :) Lennart97 (talk) 09:29, 19 October 2021 (UTC)
 * Do you have time to update Hungary anytime soon? Lennart97 (talk) 10:32, 14 January 2022 (UTC)

Vatican City is missing
San Marino, Monaco, and other tiny states are there, so why is VC missing? — Preceding unsigned comment added by 2.247.248.106 (talk) 13:46, 12 November 2021 (UTC)
 * The simple answer is that the sources used here (CIA and UN) don't include Vatican City either. A Google search suggests that Vatican age demographics may not be publically available in the first place. Lennart97 (talk) 14:02, 12 November 2021 (UTC)
