SAS is still used by companies who don't want to use open source tools and would rather pay a lot of money for an established product name and have a support line that they can call if anything goes wrong. Understandably, it's slowly dying out.

Yes, though at least where I am it tends to be a legacy system these days. So that means governments and large corporations might reasonably feature some use of it somewhere within their walls.

SAS ist still quite a big thing in the insurance sector, at least in Europe.

But the more Data Science focused roles (vs. Pure actuarial roles) are going more and more with R or Python.

Yes.

I've seen pharma, nonprofit cancer organization, kaiser permanente hospital, State government (epidemiology), etc...
