The State of Developer Ecosystem 2021
This report presents the combined results of the fifth annual Developer Ecosystem Survey conducted by JetBrains. 31,743 developers from 183 countries or regions helped us map the landscape of the developer community.
Here you can find the latest trends in the tech industry, as well as interesting facts about tools, technologies, programming languages, and many other facets of the programming world.
Note: HTML/CSS is not a programming language, but it makes sense to present its popularity alongside that of programming languages.
Please note that some aspects of the survey methodology changed between editions. In 2021 we extended geographical coverage, which resulted in differences in the shares of some languages. For example the share of PHP is 3 percentage points higher, and Python and Java are a bit lower in new regions than in the initial countries.
There are languages not listed in this table that are popular in some regions: Delphi is the primary language of 3% of the developer population in Brazil, for example, while Ruby (9%), Swift (6%), and Scala (4%) are popular in Japan.
