Hi @turtlepclark,
Canvas itself doesn't store demographic information about users. You'll probably need to reach out to your school/institution administration to figure out where they store demographics and whether you can access them, as that's really going to vary from place to place. I think the student information system (Banner, Peoplesoft, Powerschool, etc...) would usually have the data, but it may also be other places, and access would really wary based on local policies.
Sorry we can't give a more exact answer here, but I hope this helps.
