In my (limited) experience with Clojure and other functional languages, this is usually true under situations where:

1. You’re mapping or reducing some dataset

2. Your iteration logic does not branch a lot

3. You can express your transformation logic using higher order functions (e.g. mapping a reduction operation across a multidimensional array)

Some domains have a log of this style of work—finance comes to mind—others do not. I suspect this is why I’ve personally seen a lot more of Clojure in finance circles than I have in other industries.
