+# Julia User and Developer Survey
+
+
+This year, 2,565 Julia users and developers participated in the second annual Julia User and Developer Survey - up from 1,844 participants last year. This year, the survey was administered in 4 languages: English, Spanish, Chinese and German.
+
+
+The survey was presented during JuliaCon, and highlights are included below. 
+
+
+## Who Are Julia Users and Developers?
+
+
+* Survey respondents come from 102 countries and regions and speak 64 different languages
+   * 20% from the United States, 7% from Germany, 6% from India, 4% from France, and the remainder from 98 other countries and regions
+   * 91% are fluent in English, 14% are fluent in German, 13% are fluent in French, 11% are fluent in Chinese, 11% are fluent in Spanish, and more than 50% speak another language
+* More than 70% are under age 45 and more than two-thirds have less than 15 years of work experience
+* 60% are academics and 43% are professionals (survey respondents can be both academics and professionals)
+
+
+## Who Is Using Julia in Production?
+
+
+22% of professionals who have used Julia for more than 6 months use Julia in production for a business critical task and 22% use Julia for development as part of a team. 34% use Julia either in production for a business critical task or for development as part of a team.
+
+
+## What’s Changed Since Last Year?
+
+
+* 81% of respondents say the Julia community is ‘very’ (55% - up from 47% last year) or ‘somewhat’ (26%) helpful and collaborative.
+
+
+## How are New Julia Users Different?
+
+
+* New Julia users still use Python a lot (61% use Python ‘a great deal’) while users with more Julia experience use Python much less (43% use Python ‘a great deal’).
+
+
+## What Else Did We Learn?
+
+
+* Among Julia users and developers, the next most frequently used languages after Julia are Python, and Bash/Shell/PowerShell
+* If not for Julia, Julia users would be using C++, MATLAB, R, C, Fortran, Bash/Shell/PowerShell and Mathematica
+* Most Julia users started using Julia in the last 2-3 years
+* Nearly half of Julia users and developers use Julia for at least half their work
+
+
+## What Do Julia Users and Developers Like Most / Least About Julia?
+
+
+Julia users and developers most appreciate Julia’s speed and performance, ease of use, open source, MIT license and the community of Julia developers.
+
+
+From 2019 to 2020, there was an increase in the percentage of respondents looking for reduced compile times and time to first plot, and a decrease in the share of respondents who say that Julia doesn’t have all the packages they need, or that those packages aren’t mature or well-maintained enough.

+## Why Julia?
+
+
+Julia users and developers say they started using Julia because:
+
+
+* Julia seems like the language of the future
+* Faster
+* Like learning new languages
+* Preferable syntax
+* Heard about Julia from friends or colleagues
