WP 6.0 ”Arturo” Contribution Stats

WordPress 6.0 « Arturo » was released on May 24th, 2022. This version is named « Arturo », after the latin jazz artist Arturo O’Farrill.

This release is a follow-up to WP 5.9, and polishes the new Full Site Editing experience. It also introduces around 1000 bugfixes and enhancements.

As for previous releases, let’s have a look on a few stats about this release.

In the past, I already published some contributions stats for versions 5.35.45.55.65.7 and 5.9. I did it again for WP 6.0, so we can have an eye on the relative “influence” of countries and companies on WordPress Core.

Before diving into WordPress 6.0 Core contributions stats, I wanted to share a few disclaimers, for better context:

  • These stats were generated after the last Release Candidate of WP 6.0. Thanks to Jonathan who collected the props list for the release squad.
  • These statistics only relate to Core contributions (= props gained for source code contributions) of WordPress. There is a lot of other types of contributions, not listed here: marketing, communication, translation, testing…
  • To get these stats, I parsed the WordPress.org profile page of each contributor to get some public informations about them: country, employer, and wether they already contributed to WordPress Core or not.
  • It includes both Core contributions on Trac and Gutenberg pull requests on GitHub.
  • Those stats are based on what’s declared in each contributors’s wp.org profile. Users with empty profile informations are not taken into account.

WordPress 6.0 Overall Stats

519 people from at least 53 countries and 134 identified companies contributed to WordPress 6.0.

Worth noting that 129 people contributed to WordPress Core for the very first time! That’s around 25% of the total number of contributors.

The ratio of new contributors is a bit lower than in previous releases, but it still represents quite a good onboarding ratio for an open-source project.

Country ranking by number of contributions

It’s interesting to see how much WordPress is a worldwide project. Contributions come from all over the planet ♥️

The USA is still number 1 by far with 591 contributions, and Russia is behind with 373 contributions (still led by Sergey, the person who made the highest number of individual contributions on this version). Australia follows, with 308 contributions (with Peter who was the Technical Lead of WP 5.9), overtaking France (280 contributions, with me as the second most prolific contributor after Sergey) and Poland (238 contributions). The United Kingdom, Georgia, Greece, Spain, and Sweden are following.

In short, contributions from USA are relatively declining in favor of a better repartition amongst other countries. I personally think it is a good thing for the project to have big contributors not all located in the US 🙂

Countries by number of contributors

Still, contributions are not everything. Let’s talk about contributors. Instead of counting contributions, can count the people who worked on this release (= number of people credited in Trac tickets or GitHub issues)… and we have the following results :

USA is still on the top of the game with 87 people. India is still second (since WordPress 4.7) with 33 contributors.

UK comes at the third place with 20 people, Bangladesh (best ranking ever) with 15 and France with 13 contributors.

USA still dominates the stats by number of independent contributors.

It’s interesting to note that some countries are in the top ranking with only a few contributors. For example, Georgia is in the top 6 of contributions, but the country has only one contributor, George Mamadashvili!

Company ranking by contributions

Automattic is still the most prolific company with employees credited in no less than 1483 contributions (by 70 contributors), and is followed by plugin editor Yoast with 596 contributions (by 10 contributors) and Whodunit French agency (250 contributions). Next, we have GoDaddy (210), international WordPress agencies like 10up (152) and XWP (75), a freelancer (!) Advies en zo (58), and Human Made (46).

Worth noting that major stakeholders can still be categorized in three sorts of companies: agencies, plugins/themes editors and hosting companies. And of course, well… Automattic 😜

In the graphic below, you’ll see all the company credited in WordPress 6.0 and the number of contributions of their employees.

Company ranking by contributors

Of the 134 identified companies that contributed to WordPress 6.0, Automattic had by far the most contributors, with 70 people involved. 10up and Yoast are the second biggest contributors with 12 and 10 people. Multidots come fourth with 9 people. Then, we have a group of companies with 4 to 6 contributors: rtCampHuman MadeBluehostWP Syntex (the company behind Polylang), GoogleXWP, WP Engine, and AuthLab.


Except for Automattic (and also Yoast), we can see that several companies with a huge amount of contributions have a very low number of individual contributors.

Accessible WD26126.00

rtCamp1762.83
Multidots1591.67
AuthLab1452.80

That’s the case for my employer, Whodunit, with 250 contributions, but only 2 contributors (my goal for 6.1 is to change this!). At the opposite, 10up for example has a quite great ratio of contributions/contributors.


Thank you to everyone who helped
