I was wondering if anybody knows if there have been any surveys or studies with statistics of how much a given programming language is used in a given industry (e.g. % of code written annually per language)
Ultimately I am hoping to find/build a matrix like the one below
where each entry has a percentage value, and the entries in each column sum up to 100%.
The rows and columns I included above are just an example. The industry granularity can be finer or coarser than the one I used above, and the programming languages can include others too. I am aiming for a first order approximation of the full distribution of prog. languages across industries (i.e. most significant languages & industries)
I understand that the lines are very hard to draw, and that the categorization per industry is ill-defined to a large extent, but I would still like to get a sense of how predominant different languages are per industry.
- Are there any surveys or studies that tried to collect such statistics?
- This is more of a secondary question: Is there a way to collect this information using the tools or the API provided by StackExchange? Has anybody done it?
Why I am interested in this:
On one hand, I am curious to know how much we know about the distribution of programming languages across industries. The distribution exists whether or not we have ever measured it.
I also believe we can learn much about the way we use programming languages by looking at which programming languages are popular across different industries and problem types.
