Even to the point of people saying there are no distinguishing factors between them, like yourself.

Not what I said.

Both B.A. and B.S. degrees in economics require a certain number of general education and elective courses and approximately 30 to 40 credits related to the major.

My BA requires 100 credits in course, at a minimum, far more than a BS.

I think the issue here is that from an American perspective, a BA is a degree gotten from a "Liberal Arts College". We don't have those in Ireland, my BA is from a University where students study things from Engineering to medicine, history to accountancy, economics to geography.

Which is why I say, there is nothing inherent about a BA that is less maths intensive than a BS, BAs can be more, less, or the same level of math intensity.

From Wikipedia:

Whether a student of a particular subject is awarded a Bachelor of Science degree or a Bachelor of Arts degree can vary between universities. For example, an economics degree may be given as a Bachelor of Arts (B.A.) by one university but as a B.Sc. by another, and some universities offer the choice of either

The London School of Economics offers B.Sc. degrees in practically all subject areas, even those normally associated with arts degrees, while the Oxbridge universities almost exclusively award arts qualifications. In both instances, there are historical and traditional reasons. Northwestern University's School of Communication grants B.Sc. degrees in all of its programs of study, including theater, dance, and radio/television/film.

So it has far more to do with historical and traditional elements that any level of math.

Would you consider a BS in Dance to be math heavy?
