Computational Social Science
The definitions that I found are very wide and very fuzzy, and, essentially, boil down to "social science but with computers!". Is it, basically, statistics (which nowadays is often called by the fancier name of "data science")?
I doubt you can find a widely-acceptable definition of Data Science which is any less fuzzy. Computational Social Science (CSS) is a subset of Data Science. Take Drew Conway's Data Science Venn Diagram: If your Substantive Expertise is a Social Science, you're doing Computational Social Science.
Statistics is an important tool in CSS, but it doesn't cover the other types of modeling we do: Agent-Based, System Dynamic, and Algorithmic Game Theoretic to name a few.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
