Instead of belittling the publication, and you all seem to know a lot, I would suggest you publish the accurate data on the “so-called” First World countries, then a comparison could be made between his and your research. Insulting the publisher about his competence in English language is just a “cheap shot”.

the subtitle reveals part of the reason: only in half of the countries there was record search interest in 2022.

secondly: there is no way to be sure that it's predominantly World Cup which generated the record interest. For some of those countries it surely did, for others - we can't really be certain. And I'm quite comfortably sure that for Poland the cause for record interest has little to do with World Cup - it's mostly war in Ukraine.

What your data says is at most that World Cup, among other events, might generate increased global interest.

I take a look just a couple minutes ago to the same UNESCO database and i've found there exist numbers of students enrolled by school level and country. So i will redo now the graph (let me one hour work 😅).

In that database i've found "ALMOST ALL" countries except a few pacific and caribbean "island-states" and the big (and strange) absence are Canada and Australia.

And yes, you're right, english is not my first language. I take note of your suggested title. Thanks a lot!

Yes... it would be better to have used number of primary students, instead of total inhabitants. I will try to redo it later with this modification.

You must understand that it's not quite easy to find that data. If you visit the unesco database where i take from the data, there are rar missings like for example Canada number of teachers !? So, i can imagine that it will be more difficult to get the number of primary students.

But i would like it. Sure. Thanks for note it.

Responding to your first question: in education science is quite relevant the number of teachers per student. This was my target to explorer.

For me, the most unexpected result is that in this top-20 there is countries of any continent and size. This rarely happen with other "market metrics". I've curiosity to see the rank using the number of students instead the number of inhabitants. I suspect that it will not be so many differences. It only will be more accurate.

It could be possible instead, to apply a correction factor using the "life expectancy" too. Because in countries with more life expectancy, the % of students is lower per inhabitant than in countries with less life expectancy.

Thanks again.

I’m getting the idea that English is not your first language. So your title should say, “Top 20 countries with the highest number of primary school teachers per thousand inhabitants”.

Yes, there doesn’t seem to be a relationship between population and your measure. If you are actually interested in the teacher:student ratio in a classroom this doesn’t even get you close.

Notice that the UESCO data is focussed on developing nations. Many advanced nations are missing from the data. This makes the “top 20” idea flawed because it’s not top 20 in the world just top 20 in the patchy data.

Think the visualization is well done, I'm just not sure the underlying data is that interesting. It seems like there's no correlation between your two metrics, and we're also really just comparing the top performers. I didn't get much out of this other than a list of the top countries by primary school teachers per capita (is this even a great metric? Wouldn't per student make more sense? What about secondary and tertiary?)

Also, it would be interesting to take in account how many years does primary school last. Usually there is 1-2 years of difference between countries. Sometimes begin a year before and sometimes a year later, and the same happens to finish it.

So, i realize that it's not a so significant metric.

But, man, take a look to the unesco database where i take the data from... there are countries (like Canada!!) without data about primary school teacheres 😮 so... starting from there, you can't expect to get very accurate images about these "international comparatives".

It's a RELATIVE metric (X things each Y population). In education science is quite relevant the number of teachers by pupil.

Certainly, it would find quite more convenient to calculate this relative metric using "number of children with primary school age" instead of "total inhabitants". But usually these both metrics are quite related. But i know that it's not the same. For example, for countries with more old people it probably the % of children is lower than countries with a lower life expectancy.

Mmmm... maybe i could apply a "fix factor" using the life expectancy for each country (i collected it for previous graphs i done this month).

So, consider this a "first version" 😁
