It sure is. Not only is Architecture heavy in mathematics, it also includes aspects of science, engineering & technology.
The following is a list of designated Architecture degree programs:
- Architectural and Building Sciences/Technology
- Architectural Engineering Technology/Technician
- Architectural Drafting and Architectural CAD/CADD
An accounting major, obviously, involves a significant amount of Mathematics, so it is generally considered STEM.
However, accounting isn’t included on the U.S. list of designated degree programs.
Yes, Finance is considered STEM, however it isn’t included on the U.S. list of STEM Designated Programs.
Despite not being included on that list, “financial services” was included on the DHS’ STEM Jobs Act in 2012.
So, the field of Finance is a STEM field.
