Is Tiobe Index misinformation?
Every month a new Tiobe Index is published purporting to show the most popular programming languages. Except, if you look at other programming language popularity surveys, lists etc, the Tiobe Index increasingly seems to be at odds with everybody else.
Take the programming language C. As you can imagine I have a particular interest in it. I was at first delighted when I saw it at #3 in the Tiobe Index. In fact, in their most recent index it is listed as the 2nd most popular programming language. Well that is just crazy. No matter how much I might want it, there is no way on Earth that it is the 2nd most popular programming language.
It’s not just me saying it. Let’s look at who else says it.
|Tiobe Index||2||Updated monthly|
|GitHub Octoverse Programming languages||9||Annually- this is October 2022|
|Reddit Programming languages||10||Subreddits for programming languages|
|Red Monk Programming Language Rankings||10||June 2022. Updated every 6 months|
|StackOverflow developer survey||11||Annually|
|Statista most used programming languages 2022||11|
|Hackerrank Developer skills report 2023||12|
There are other programming language lists or surveys but those show what I mean. No one else has C anywhere that high. Here it’s in positions 9-12 with an average roughly around 10.5 if you exclude Tiobe or 9.3 if you don’t. I think their methodology is flawed and biased by age. Older languages appear to carry more weight.
