I try to track the actual download events and derive some information about them. This post is about the timerange June 1st until Aug 12th (today). The basic numbers are, that Sage is downloaded most often in the USA (35%), followed by Germany (7%), France (5%), UK, Italy, Spain, Canada, China, Brazil and Japan (4 to 2 %). On average, Sage was downloaded 150 times each day during the last semester, and a bit more than 100 times during summer break. I hope, numbers will go up again ;)
But that's rather boring and I tried to put the numbers in context. I focused on those countries with more than one million inhabitants and scaled the download numbers with the population size or with the number of internet users. To my surprise, the hit-list looks totally different now!

I was somewhat surprised to see Switzerland, Austria and New Zealand and Uruguay on top! Concerning Uruguay, I know that they use Sage at University.

For me, that's also rather interesting. Of course, those countries with only a few internet users are easily on top (Niger), but e.g. Guatemala has more than 1 million users and so far I have never heard of them using Sage. In this context, our top 3 from the pure download numbers are way down below: USA #23, Germany #21, France #19!
Now the important questions:
What does that say about Sage adoption? Market potential? Is Uruguay a maths country and the USA not? Does it depend on the average income, GDP, ... (Switzerland & Austria vs. Uruguay & Guatemala?!?!) ... or just statistical noise?

Regarding the Guatemala datapoint I've been encouraging (requiring) my students to use Sage in their courses. So far I know that it's been used in Calculus, Differential Equations, Discrete Mathematics, Abstract Algebra, Signal Processing and maybe a couple more.
ReplyDeleteDeveloping countries have a very strong cost incentive to use Free (and free) Software.
ReplyDeleteyeahr, i'm hope and i'm sure free software in emerging countries has a good future - including Sage of course. also, due to the economy downturn, i hope more and more universities in western countries will revisit their expenses and may choose Sage.
ReplyDeletei didn't know that about guatemala, but sounds indeed interesting, thanks!
