Number of people completing a language tree

We already have the number of people that have started or are learning a language.

Do we have a count on the number of people having completed a particular language tree.
Or the number of people at the top levels - above level 20 to 25.
Or the number of days it takes to complete a certain language tree - on average.
(Or the number of people at 25%, 50%, 75% completion status.
This is useful, because it will show us that certain languages don't get completed.)

For example, the new Chinese course was recently released.
Is there a count on the number of people that have already completed it.

This kind of data would be very interesting, but Duolingo generally does not release it.

It might be demotivating for those on the bottom of the spectrum and could potentially even stimulate bad learning habits. In the end it also doesn't tell the whole story, i.e. somebody doing a tree of a language they already speak well. Certainly interesting, but it might be without practical implications for language learners.

I think Duolingo is good with teaching reading and writing and some listening and not a lot of speaking.

Fluency at an informal level, has to do with sentence construction, speed of communication, understanding context, expressing an idea, range of vocabulary, grammar nuances, multiple tenses, and so on.

Improving fluency could be done with possibly listening to the radio and songs and podcasts; watching tv, youtube, movies; engaging in conversations; reading books and newspapers; reading websites or course books; and so on.

Maybe doing the reverse tree or laddering would help. Writing an essay could help. I think using a chatbot could give an edge - assuming smart chatbots. Only a tutor could possibly help you exercise the full range of the language and topics and constructs.

Anyway this is my understanding.

Yep, the data is right here: https://duolingo.eu/ Only three people have completed the Chinese tree so far.

Neat, but that site does not track every user and thus cannot be seen as representative for the userbase as a whole.

This is just sample of the population, would be interesting to see the whole population on a chart like this, particularly the numbers of people who've completed each language. Thanks for sharing.

Who is maintaining that site? I am on there but don’t remember signing up. Also, the number of trees I’ve finished is wrong (it should be ten). Cool site!

The number of trees is very wrong in my case too... if this is a sign of how reliable the site is, I'd say it can't even be seen as representative of the userbase in it, let alone for the userbase as a whole! :-p

Completing tree does not necessarily equate with learning the language I have decided, since some of my skills at golden but I really would not be able to use even the parts of the skill that have been presented to me outside of the DL model. This is because DL has a kind of 'style' that I have adapted to increasingly through the tree and because most of it is from the target language to the base language and can be guessed.

And getting through it quickly does not mean one is more proficient, as there is a lot of learning in the strengthen exercises and on the discussions.

But a very good start, I think.

It's definitely worth doing the reverse tree, from your target language into your first language. In your case I'm guessing your reverse would be English for French speakers? I've found mine surprisingly hard, even after knowing all the material well from doing the tree the opposite way round, since it's much harder to give answers in the language you're learning and consistently not make errors, than it is to consistently be perfect when writing in your own language

Here's a response I commented a while ago to a few different posts that all asked what proportion of duolingo users completed their tree:

In 2013, 1 in 100 members had completed their course

(there were 10,000,000 registered users, and 100,000 of them had completed their course)

In 2017, there are now over 150,000,000 registered users (around 15 times as many as there were in 2013), so the percentage of those who complete a course could have changed dramatically. We can only assume that it's still somewhere around 1 percent though, since we have no data to suggest otherwise.

This 2013 article, which refers to statements from Luis von Ahn (the founder of Duolingo) gives both the numbers for 2013: http://edition.cnn.com/2013/10/15/tech/mobile/duolingo-incubator-language-teaching/

Duolingo total registered users in 2017: https://en.wikipedia.org/wiki/Duolingo

I'd guess that it would be a little lower now due to changes in the demographic: more kids (?) and more fame (more people who just try it / want to check it out rather than really being interested in learning a language).

Well at least 1 person that I know of so far. I have finished 3 trees so far.

I've completed the Spanish, Italian, and French tree.

I am really in Awe of a lot of you with multiple languages on your profile. I added Spanish about a month ago, and after about three days decided it was not a good idea and went into my account and deleted it.

Aside from percentages, it would be interesting to know the number of people who have topped out in a given language.
