Some Esperanto course statistics :)

Hey everyone, I got some statistics back from Duolingo I'd like to share with all of you.

Geographically, around 40% of our learners are based in the USA.

Every day, 30 people finish the tree on the web! Most of our learners, however, use the course on mobile and we don't have statistics for how many learned it on mobile. I think we can safely conclude that at least 60 people are completing the tree per day... most likely this number is closer to 100.

When I hear more stats, I'll let you know! :)

Awesome! It's cool that you can get statistics like that.


I just found an old post article (2014-03-06, http://www.fastcolabs.com/3027354/the-founder-of-duolingo-tells-us-the-secret-to-creating-value-from-chaos ) which says: "Now, 80% of Duolingo’s 25 million users are coming from mobile (...)". If this is still true and also true for the Esperanto course, then 30 people (finishing the tree every day on the web) mean about 20 % of all people finishing every day and 100 % are about 150 people a day. If and only if... But this gives an estimate.


Thank you for sharing this. 30 or even up to 100 people finishing the tree every day really sounds very nice :) This would be about 10,000 or even 30,000 a year... Would Duolingo be so kind as to inform you which percentage begins to learn on the web (the others on mobile)? Then the estimation about how many people finish on mobile would be a little bit more secure.


I'll ask next time I have more questions about statistics to batch them into a single message. :)


I found an old article about this, see below.

WOW! That's unbelievable but I'll have to believe it! Well done!!


Do you have stats as to how many people complete the tree more than once?


30 people every day?!? Wow. That's brilliant! :D


What is the current rate of completion two years later? Do we have an update?


also, how many people eventually finished, out of the 1.3million?


I wan't to know the same thing.


100 trees * 30 days * 12 months = 36 000 invested learners per year. 36 000 * 30 years = + 1 080 000 Esperanto-readies. Just by English Duolingo course. But the more people know about the language, the more they will find useful to learn it. The future is even better.



Careful with the extrapolation there and don't get overly excited. There is a pool of learners, such as me, who had heard of Esperanto for years but never took the trouble to find out more about it. As I was already in Duo for another language, it was easy to make that jump and enroll in Esperanto.

There have to be a limited number of people in my position, and when Duo runs out of us, the Esperanto subscription rate is going to drop significantly. We are at the top of a bell curve here and will soon face a drastic drop in the rate of new Esperanto learners.

If we had statistics on the number of students of in a typical Duolingo language course over a period of time, we could make more meaningful predictions of where we will be in one year and further, but unfortunately carrying out our first year's growth over thirty years is statistically impossible.


I agree that it is not wise to extrapolate that much. But I do not think the effect you speak of is still that important. I think most of those people already began to learn Esperanto.

I still suppose that something like 0.2 to 0.7 % of the Duolingo learners of languages other than English would be possible over quite a long time. The existence of the Duolingo Esperanto course will contribute a lot to the image of Esperanto in the public. Quite often you still find articles who speak of Esperanto "slipping into the past" and similar errors. Probably during the next years such articles will appear a lot less.

Something remarkable is that nowadays language learning sites with at least two dozens of languages usually offer an Esperanto course or other learning tools. See http://tinyurl.com/lingvolerniloj It's not just Duolingo who offers something for Esperanto - it's every major language learning site with many languages.


I think also it's exciting to see people not just starting the tree but finishing it. People start language trees on here all the time and then desert them because of time constraints or 'it's too hard' etc. It's more interesting/exciting/positive for Esperanto how many people are actually getting to the end of that tree. I have no idea how it compares to other language trees, but for a language often derided as fake or dead or whatever, thirty people a day having built a strong foundation seems pretty cool.

They may not all become enthusiastic Esperantists, but that seems like a good uptick in the number of people who 1) are aware the language exists and 2) have at least a basic knowledge of it. It's exciting stuff! :)


I think your correct to be cautious about overly optimistic numbers. However, I do think there will be a good number of people that learn about Esperanto through Duolingo. I had never heard about Esperanto before this website. I googled it because I had no idea what country spoke that language. I found the story fascinating and here I am learning Esperanto along with Spanish that I had wanted to learn for decades.

I also think things tend to grow exponentially, I see that with Spanish, each successive million learners seems to come quicker and quicker. I also think that when Esperanto from Spanish, and other potential Esperanto courses are developed, you will see a smaller percentage of the total learners based in the US.


It's increasing every day, english and spanish (by leaps and bounds.) I think it's safe to say Esperanto is here to stay.


In the rate of 100 trees completed a day, in 5 years, all the current subscribed Duolingo learners, would know the basics of Esperanto. Let me explain better: 100 trees30 days12 months= 36 000 learners*5 years= 180 000 learners The current number of Esperanto learners on Duolingo is 166 000


The worth off the network is n^2 so it increses at a significantly rapid pace


Great! That's a lot of people!


Really interesting. I wonder if, being so simple and short the completion rate will be higher. For example once i started to focus on esperanto i went from basics / accusative to finished tree all golden in 20 days compered to about 8 months for my first tree in spanish. I was soooo pleased. Maybe we should be promoting esperanto as the warm up exercise for any and all other languages. A quick win to boost confidence etc


Thanks for the stats. Interesting to know 40% of learners are in the USA. That is quite a lot of people finishing the tree every day. Hopefully I am one those 60 or so people a day next week sometime as I only have 2 skills left. However, it is exam week at my school so I can't spend a lot of time on Duolingo.


I use the web if I'm home on my computer, and the phone if I'm at work (during lunch). This is good to know. I'll be sure to finish up on the computer so the statistics are captured.


It has been quite some time, I do hope you have further statistics! Please share them even if they are not as bright, as the enthusiastic community would probably do something about it ;)

On the other hand I am really surprised that you guys do not have statistics for mobile. You have created such a wonderful app, probably one the best out there, and you did not collect statistics! IMO it is one of the very first things to do as long the information is not sensitive.


Chuck, how many keep going after completing the tree, do you know?


I have one curiosity: how are the reports evolving over time? I believe I saw some data after the beta was reached, really looking forward to more information, thanks.


I am very proud that my upvote was the 99th one. I love upvoting posts and getting them to numbers with all the same digits. I don't think it's surprising that I always make wishes at 11:11.


That's amazing. I wonder how many people pursue the language after that but I feel like completing the tree is a solid start for a language like esperanto. That's great news!

I wished there was a way to contact them or have a standard message pop up at the end to congratulate them and give them link to Esperanto resources and communities. Or maybe have an extra lesson (possibly one bought with lingots) which presented them.


There is a link at the end of the last part of the course. I also wish it were bit more prominent....



The link is promoted elsewhere, and can be reached as afterduolingo.com


Cool, I haven't finished it so I didn't know.
