"Data science" is a term devised by bureaucrats who do not have the simplicity to just describe it as "economic and social statistics" although, to be fair, the term is intended to imply the use of statistics in performance indicators that may be used to describe performance as it relates to either outputs or outcomes of government (or the private sector). This is one of the most poorly implemented areas of the public sector, as its implementation in relation to programs seems to have been overseen in many cases by people with very little training in statistics or in the concepts of performance indicators. As such, it is likely to be a very lucrative/productive area in the future for anyone who has some basic training in "data science".
