Data Science Survey 2018 Results By Numbers

Data Analysis, Machine Learning, and AI are rapidly growing in popularity and drawing more and more attention in tech news. How does the data science world look today and how is this industry sector evolving? What types of activities are data scientists primarily involved in? What programming languages and tools are in use? To answer these and many other important questions, last spring JetBrains conducted a Data Science Survey collecting responses from over 1,600 data scientists living in the US, Europe, Japan, and China.

We are super-excited to share with you some of our incredible findings, along with the raw survey data which you can use to draw your own conclusions!

Did you know that Python is now the most popular language among data analysts and engineers? How about that most people assume that Python will remain the primary programming language for data science for the next 5 years? Learn more about these and other insights in the survey infographic:


View the results of Data Science Survey 2018

Key Takeaways

  • Data processing, data visualization, and basic statistics are the top three activities that data scientists are involved in.
  • Python is the main programming language for data analysis with most users not willing to migrate to other languages.
  • Most of the respondents believe that Python will remain top for the next 5 years.
    7% of respondents identified as not professional data scientists want to adopt Kotlin in the nearest future.
  • Apache Spark, Apache Hadoop, and Apache Hive are the top three big data tools.
  • Jupyter Notebook is the top code editing tool for people involved in data science, followed by PyCharm and RStudio.
  • Nearly 80% of those using deep learning libraries use TensorFlow.
  • 78% of respondents use their local machines to perform computations.
  • AWS is the most popular cloud service provider among data scientists.
  • 81% of data scientists analyze data for non-IT industries.
  • Get more insights from the full report.


We distributed the survey via targeted ads on Facebook, LinkedIn, and Twitter. We filtered out those replying “I’m not involved in data analysis” with the first questions. In the US, Japan, and China, we collected 400 complete and valid sets of responses from each country, and we used quotas to get another 400 responses from European countries.

Important Note: Some inevitable bias may be present since the survey was organized and promoted by JetBrains and some JetBrains users might have been more willing to participate.

Want to dig into the raw survey data to draw your own conclusions?

We couldn’t include all the potential findings in the report without it becoming bloated. If you have any specific questions that are unanswered, send them to us and we’ll dig into the data for you for an answer. Or if you want to delve into the data yourself, we’re also sharing the raw survey data, which anyone can use to arrive at their own conclusions and additional findings. PDF version of the infographic is also available if you’d like to print it out or read it as a file.

We hope the survey findings will help all of us better understand the current state of the Data Science community, see the big picture, and get answers to some of our burning questions. We’d be very interested to learn about your findings! Please share them on Twitter or other social media, mentioning @jetbrains‏ with the #datasciencesurvey hashtag. We’re also extremely open to any suggestions and feedback related to this survey so we can run an even better one next time.

Finally, we would like to just say a huge thanks to the participants of the survey!

Developer Ecosystem Survey 2018: Raw Data Available

Early this year, we ran our second yearly Developer Ecosystem Survey to reveal the most significant facts about developers and technologies.

Since this June, we’ve been sharing these Infographics showcasing the most interesting results and insights from an even broader range of developer topics than last year.

As the study consisted of over 150 questions, it was impossible to cover them all in the Infographics. So now, same as last year, we are publishing the anonymized raw data from the survey. If you’re interested in discovering development trends, be our guest – go right ahead, dig deeper into the data, draw your own conclusions and glean additional insights like we did!

DevEcosystem18 Raw Data Is In

What kind of interesting facts did we dig up? Well, we found out that JetBrains customers code for 5 hours (21%) a week more on average than those who don’t use JetBrains tools! At the same time, they get 15 more minutes of sleep (that’s 5%) than the average coder. Fascinating stuff! Maybe it’s because JetBrains users love programming and sleeping, but programming more!

Before analyzing these data, please keep in mind the following facts about the sample:

  1. The data-set includes all of the 13,000+ responses collected from January to April of 2018 from both JetBrains “internal” and “external” channels. By “external” channels we mean channels such as Facebook Ads, Twitter Ads, and Google Adwords. By “internal” channels we mean JetBrains’ own communication channels such as our blog post, JetBrains Twitter accounts, JetBrains Facebook, and the JetBrains’ Internal Survey Panel. When comparing your own results with our Infographics results, please bear in mind that to minimize possible bias, the data of the Infographics include only responses coming from advertising (external channels).
  2. The data are anonymized, with no personal information or geolocation details. Moreover, to prevent the identification of any individual respondents by their verbatim comments, we have purged all open-ended fields. We have also merged any answer options that collected fewer than 10 responses into the “Other” answer option.
  3. The data are not weighted. We used our own population weights for post-stratification of Infographic data, to correct for the fact that countries with similar sample sizes may have different actual numbers of developers. We’re not sharing these population weights so you’ll need to apply your own weights when analyzing the data.
  4. To better understand the logic of the survey, along with the data-set we’re sharing the survey questions, with all the survey logic, in English.

Celebrating the Drive to Develop on Programmers’ Day 2018

Last week on the 256th day of the year individual developers and organizations all over the world celebrated International Programmers’ Day.

We, at JetBrains, with so many incredible developers around us couldn’t just sit back and let this day pass without some kind of recognition. We asked all the programmers who follow us on social media (mostly Twitter) to use the hashtag #MyDriveToDevelop and tell the world what programming meant to them – what was their “Drive To Develop”.

Programmers' Day 2018

As for the results, developers from over 25 countries on all of the continents (with the exception of Antarctica) posted their own personal stories.

We want to thank everyone who took part, we read every single one of the #MyDriveToDevelop hashtag tweets and comments and were truly fascinated by how much the programmer profession means to so many of you.

It would be impossible to share all the comments in this blog post and also unfair to post just a few and call them the best because all of the tweets and comments were amazing, full of warmth and consideration. So what we’ve done is prepare this cloud of words to depict the most frequently used words and give you an insight into what drives developers with their work.

Programmers' Day 2018: cloud of tweets and comments
If you want to read all the original tweets just browse Twitter, Facebook or VK with the #MyDriveToDevelop hashtag.

Each and every programmer has their own #MyDriveToDevelop, however there are some commonalities that we’ve noticed.

Making a difference
Creating opportunities, simplifying the processes, building something that others find valuable.

Collaborating with others
Connecting the community, making cool things together, sharing knowledge with others, helping other developers to achieve the goals they have.

Being a challenger
Staying curious and hungry to experiment, improve and constantly evolve. Turn routine into fun and complexity to simplicity.

Being a dreamer
Making dreams come true, turning ideas into things that have a purpose.

Being a superhero
Having unlimited possibilities, solving complex real life problems, improving everyone’s life, making the world a better place with help of the software!

With the Drive To Develop nothing is impossible.

We at JetBrains could not agree more, all the things people mentioned about why people love programming, all resonate deeply with all of us in this incredible field of work. There is something that drives us as programmers to seek out the challenges, make solutions, and have an impact on the world, regardless of where you are in the world. We are just so glad to have a community of similarly driven people.

Stay passionate, stay curious, and may your #MyDriveToDevelop always be with you!

The Drive to Develop

PS: At JetBrains, we celebrated the Programmers’ Day not only online but also offline, in the company of great colleagues in each of the JetBrains offices. We had some snacks, drinks, and games. And of course cake!

Programmers' Day 2018: cake

Educational Products 2018.2: Scala and Project-Based Learning

Riding the 2018.2 release wave that has recently hit our IDEs, we’re also updating our Educational Products so that your everyday learning and teaching is full of even more joy and the drive to spread knowledge.


Scala is now supported

We’re happy to welcome Scala as the next programming language supported by our Educational Products. Educators can now share their Scala knowledge in the form of coding tasks and custom verification tests, the same they do for Java, Kotlin, and Python.

Unfortunately, we don’t have any Scala courses yet. We need your help!

If you’re an educator, please take a look at the Quickstart Guide and try to create your own course. If you need our support or want to help create Scala learning materials, please let us know. If you’re a learner, do share your favorite Scala learning materials with us! Just leave a comment here or contact us on Twitter.

Project-based learning, first steps

Project-based learning is about making something real, driving results that help learners stay engaged and motivated. We believe it is of paramount importance especially in learning programming. In this release, we’ve implemented Framework Lessons which is is the first step towards making project-based learning a first-class approach supported by our Educational Products.
