What follows is a little survey I did on indeed.com on 4/28/17. I started off just looking for the popularity of the R language for data science but wound up broadening the search terms. I limited the search to my home state of California. It is not in any way a scientific survey but it did prove interesting as far as it went. R ranked pretty high. Right behind Python and ahead of C++. C and SQL were the top two languages. Java was 3rd. We already offer a short coding class in Java and are developing one in Python. Perhaps we will do R next. A couple other observations are that the open languages are firmly in the lead. SAS had the most mentions of the commercial statistical packages.
I often say that SQL is a foundation skill for data analysis. This survey seems to bear that out. To that I would add Python and/or R for those interested in a data science career.
