More than 15K people participated in the Developer Ecosystem Survey 2018, but only the responses of 6K respondents were included in this report.
We used Twitter Ads, Facebook Ads, Google Adwords, and JetBrains' own communication channels to invite potential survey respondents to take part. To minimize bias, the reports only include responses coming from Twitter Ads, Facebook Ads and Google Adwords.
We collected enough samples from Argentina, Brazil, Canada, China, France, Germany, India, Japan, Mexico, Poland, Russia, South Korea, Spain, Turkey, Ukraine, United Kingdom, and the United States to feel our sample is representative of the current Developer Ecosystem. As around 70% of all the developers in the world are based in these countries.
To minimize possible bias against non-English speaking respondents, we conducted the survey in 6 languages.
We also performed weighting to present differences in developer numbers by country and the number of students in different countries.
Despite these measures, some bias is likely present as our users may have been more willing on average to complete the survey.
Thank you for your time!
