Duolingo Fun Facts
There are over 300 MILLION users on Duolingo! Imagine it like this: A country filled with just Duo users, which happens to be the population of the United States!
Monthly users include 25 MILLION. Still a large number.
The average number of Duolingo exercises completed MONTHLY .... brace yourselves..... 7 BILLION!!!!! That's like one exercise for every person on Earth!
The average number of times per second that the Duolingo database is updated is 3,000 TIMES!
You may think like, how does Duolingo make money if it is free? Some explanations are Plus and ads, but would you imagine that totals out to $108.3 million USD?
Duolingo is valued at over $700 million USD. This is almost the GDP of the country Monaco!
People in North Dakota and Montana on average maintain an average of 120-day streaks.
The correlation coeffcient between Internet access and language learners on Duolingo is 0.64, which is quite high.
Duolingo is the most popular language-learning website in the world. BY FAR!!
Wow, that’s crazy! To the people who are saying that he copied it, well sure he did, but he’s sharing it with the world. I know that I wouldn’t google things about Duolingo so he did it for me. I’m glad that I wasn’t the one to have to the digging. The stats in this post are insane! I am amazed at Duo’s progress!
i was trying to spread the word.Like lucille said, no one would spend their time looking for these facts. I was just wishing to share. I am sorry if it offends you.
I see you have now changed your title - removing "that nobody knows" - it was that tag that really annoyed me.
It's the use of the word 'facts' for lots of completely unattested and unsourced figures that bothers me. It doesn't take much effort to give sources if you have them.
The correlation here spoken about is the Spearman's correlation or "rank correlation". It is a weaker correlation measure than the "usual" (i.e. model based) correlation method.
In the present example the "usual", model based correlation would find a relation between :
- number of inhabitants of a country who have internet access
- number of inhabitants in a country who are studying languages
For example, a country with 5M inhabitants having internet access may have 1M of language learners. Another with 2M inhabitants having internet access may have 0.6M language learners.
The correlation measures the relation between the numbers. The relation then allows to estimate the number of language learners in a country if one knows the number of inhabitants having internet access.
The "rank correlation" will first :
- rank the countries according to the number of inhabitants who have internet access (1st, 2nd, 3rd, etc)
- rank the countries according to the number of inhabitants who are studying languages (1st, 2nd, 3rd, etc)
So, a country may be ranked 1st in internet access and 3rd in language learners, another may be ranked 5th in internet access and 4th in language learners.
The correlation measures the relation between the ranks. If the correlation is strong then one could estimate that a country who ranks 15th in internet access will also rank around 15th in language learners. But it doesn't give an estimation of the number of language learners.
This correlation is frequently used when there are a few countries with a big population and many with a little one (or the opposite).
The value of correlation coefficient always lies between 1 (perfect relation) and 0 (no relation). IMO 0.64 for a Spearman's correlation is indicative but not very strong.
Number 7 is interesting. Whose doing the math to figure that out lol?
It's probably just because there are fewer people doing Duo in North Dakota and Montana, but they are more commuted than other areas. Low quantity (of people) plus high quality (of streaks) equals higher averages.
Ad 8. Correlation between what? How much sb spends on duo and how good he gets at language or what? I think I don't get neither of two things right
Ah correlation coefficient, I remember learning about that in math. Tough stuff.
Wow! I personally am impressed with...
all those languages!
How do you learn so many? Can you remember them all or did you just dip into a few and forget about them? Which one is your favorite?
I’m having trouble with #6: first Monaco is not a country; second according to the World Bank back in 2011 the GDP was 6.075 Billions of US dollars. But interesting facts all together, thank you!
Awesome facts! By the way, with the numbers in North Dakota and Montana, it is really time to add the Lakota and Dakota languages!
Just wondering, fun fact 5 says that duolingo makes $108.3M. Is that all time, yearly, monthly, daily, or what?
Fun Fact: I read fact 7 on the 120th day of my streak. Lol
10. The website was launched on November 30, 2011!
11. Duolingo has its own headquarters in Pittsburgh, Pennsylvania, USA!
12. In 2013, Apple chose Duolingo as its iPhone App of the Year, the first time this honor had been awarded to an educational application!
Does anyone know why MT and ND correlate with higher Duolingo streaks? I'm mostly interested in the relationship between users and those particular geographies.
I have one. The owl will come after you during the night and kill you if your stop your streak. he will also write on the walls of your bedroom in whatever language you are learning, he/she should have stayed on there streak.
What does? I feel Duolingo is pretty ahead in the game in terms of social networking compared to websites such as Mango Languages or Pronunciator. I am doing an upcoming post on more resources for Duolingo in a few minutes. Stay tuned!
well it's a language learning site not a social network right? (tho it used to be better when the streams were around)
Please forgive the rudimentary question. But,this is something I overlooked from the very beginning. Is one to go through all five levels before progressing to the next lesson? Or, should I achieve level one on each lesson int he course, then step up to level two, etc, on each lesson. Which way was the intent when Duolingo was designed? Thanks!
From the makers of Duolingo........
Feel free to ask more questions. I'll get back to you in a day at most
