The Campaigns & Elections market is approximately 20,000 students per year, though enrollments tend to fluctuate based on the election cycle. The course is offered at least every election year at most four-year schools, and frequently once per year. Campaigns & Elections is sometimes taught as a standalone course (especially in large research universities where there are a number of faculty who teach in the political behavior area), and sometimes in combination with other political behavior topics. The combination courses, taken primarily by upper level Poli Sci majors, are almost as common as the single-topic courses.
