How many years of social studies does a four year college require for admission?

Most four-year colleges don't specify a *number* of years of social studies for admission. Instead, they require a certain number of *units* or *courses* in a broad range of subjects, often including social studies as one category. This usually involves at least one year (3-4 courses) but the specific number varies greatly depending on the high school and the college's requirements. The focus is on demonstrating a well-rounded education, not necessarily a precise number of years in any one subject.
