Which math courses are recommended or required for the concentration?

Multivariable calculus and linear algebra, to at least the level of Math 19a and 19b, are required. The most common way for concentrators to fulfill the math requirement is to take Math 21a and 21b, but there are a variety of other fairly common choices. Students considering graduate school in Statistics are strongly recommended to take additional mathematics courses, especially real analysis (e.g., Math 112).
