I've been following programming language statistics for several years. There are a number of data sources including code repositories, Q&A discussions, job advertisements, social media mentions, tutorial page visits, learning video views, developer surveys and more. Data is published at different times, none can be considered accurate and all have flaws -- but they can be useful for spotting industry trends.
GitHut
GitHut is a relatively new resource which analyzes 2.2 million active repositories on GitHub. The top ten:
- JavaScript
- Java
- Python
- CSS
- PHP
- Ruby
- C++
- C
- Shell
- C#

Jobs Tractor language trends analyzes many thousands of job postings on Twitter. The latest figures from September 2014:
- Java
- Objective-C
- PHP
- SQL
- Java (Android)
- C#
- JavaScript
- Python
- Ruby
- C++
TIOBE Index
The TIOBE Index rates languages on the number of skilled engineers, courses and search engine rankings.
- C
- Java
- C++
- Objective-C
- C#
- JavaScript
- PHP
- Python
- VisualBasic.NET
- Visual Basic
Completely Unscientific Meta-Survey Ranking
If we combine these four surveys, we arrive at this result:
- Java (all)
- JavaScript
- PHP
- Python
- C / C++
- C#
- Objective-C
- Ruby
- Visual Basic
I combined C and C++ and ignored CSS and shell scripting. CSS isn't a programming language as such although preprocessors come close. Shell scripts are useful regardless of whatever technologies you adopt but you won't find jobs where it's the only language you need.
