TIOBE Index for March 2019
March Headline: Powershell enters the TIOBE index top 50
There are hardly any interesting changes in the TIOBE index this month. We had to use our magnifying glass to spot some news, i.e. that Powershell entered the TIOBE index top 50. The Powershell scripting language is more than 12 years old and it has been in the top 50 before. Powershell is typically used for basic scripting. Until recently it was only available for Windows but Microsoft used its .NET Core platform to create Powershell Core. This version is open source and runs on all major platforms. This might be the reason why Powershell is getting more popular again.
The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.

Other programming languages
The complete top 50 of programming languages is listed below. This overview is published unofficially, because it could be the case that we missed a language. If you have the impression there is a programming language lacking, please notify us at firstname.lastname@example.org. Please also check the overview of all programming languages that we monitor.
The Next 50 Programming Languages
The following list of languages denotes #51 to #100. Since the differences are relatively small, the programming languages are only listed (in alphabetical order).
- 4th Dimension/4D, ABC, ActionScript, Alice, Apex, APL, Avenue, bc, Bourne shell, C shell, CL (OS/400), Clojure, Common Lisp, Crystal, cT, Elixir, Elm, Emacs Lisp, F#, Forth, Icon, IDL, Inform, Io, Korn shell, LiveCode, Maple, Mercury, Modula-2, Monkey, MQL4, MS-DOS batch, NATURAL, OpenCL, Oz, PostScript, Pure Data, Q, Ring, S, SPARK, SPSS, Standard ML, Stata, Tcl, Tex, TypeScript, Vala/Genie, VBScript, VHDL
This Month's Changes in the Index
This month the following changes have been made to the definition of the index:
- Santiago Segui suggested to add GML as a new programming language to the TIOBE index. GML meets all requirements. So it will be tracked from now on. This month GML entered the TIOBE index at position 193.
- GAMS is a programming language that also qualifies for the TIOBE index. Salvador Doménech Martínez proposed to add it to the TIOBE index. GAMS debuts at position 240 in the TIOBE index.
- There are lots of mails that still need to be processed. As soon as there is more time available your mail will be answered. Please be patient.
Very Long Term History
To see the bigger picture, please find below the positions of the top 10 programming languages of many years back. Please note that these are average positions for a period of 12 months.

Programming Language Hall of Fame
The hall of fame listing all "Programming Language of the Year" award winners is shown below. The award is given to the programming language that has the highest rise in ratings in a year.
Bugs & Change Requests
This is the top 5 of most requested changes and bugs. If you have any suggestions how to improve the index don't hesitate to send an e-mail to email@example.com.
- Apart from "<language> programming", also other queries such as "programming with <language>", "<language> development" and "<language> coding" should be tried out.
- Add queries for other natural languages (apart from English). The idea is to start with the Chinese search engine Baidu. This has been implemented partially and will be completed the next few months.
- Add a list of all search term requests that have been rejected. This is to minimize the number of recurring mails about Rails, JQuery, JSP, etc.
- Start a TIOBE index for databases, software configuration management systems and application frameworks.
- Some search engines allow to query pages that have been added last year. The TIOBE index should only track those recently added pages.
Frequently Asked Questions (FAQ)
Q: Am I allowed to show the TIOBE index in my weblog/presentation/publication?
A: Yes, the only condition is to refer to its original source "www.tiobe.com".
Q: How may I nominate a new language to be added to the TIOBE index?
A: If a language meets the criteria of being listed (i.e. it is Turing complete and has an own Wikipedia entry that indicates that it concerns a programming language) and it is sufficiently popular (more than 5,000 hits for +"<language> programming" for Google), then please write an e-mail to firstname.lastname@example.org.
Q: I would like to have the complete data set of the TIOBE index. Is this possible?
A: We spent a lot of effort to obtain all the data and keep the TIOBE index up to date. In order to compensate a bit for this, we ask a fee of 5,000 US$ for the complete data set. The data set runs from June 2001 till today. It started with 25 languages back in 2001, and now measures more than 150 languages once a month. The data are available in comma separated format. Please contact email@example.com for more information.
Q: Why is the maximum taken to calculate the ranking for a grouping, why not the sum?
A: Well, you can do it either way and both are wrong. If you take the sum, then you get the intersection twice. If you take the max, then you miss the difference. Which one to choose? Suppose somebody comes up with a new search term that is 10% of the original. If you take the max, nothing changes. If you take the sum then the ratings will rise 10%. So taking the sum will be an incentive for some to come up with all kinds of obscure terms for a language. That's why we decided to take the max.
The proper way to solve this is is of course to take the sum and subtract the intersection. This will give rise to an explosion of extra queries that must be performed. Suppose a language has a grouping of 15 terms, then you have to perform 32,768 queries (all combinations of intersections). So this seems not possible either... If somebody has a solution for this, please let us know.
Q: What happened to Java in April 2004? Did you change your methodology?
A: No, we did not change our methodology at that time. Google changed its methodology. They performed a general sweep action to get rid of all kinds of web sites that had been pushed up. As a consequence, there was a huge drop for languages such as Java and C++. In order to minimize such fluctuations in the future, we added two more search engines (MSN and Yahoo) a few months after this incident.
