Question: And, do you also have information on the total number of instructors in each department?
SQL: SELECT count ( DISTINCT T2.id )  ,  count ( DISTINCT T3.id )  ,  T3.dept_name FROM department AS T1 JOIN student AS T2 ON T1.dept_name   =   T2.dept_name JOIN instructor AS T3 ON T1.dept_name   =   T3.dept_name GROUP BY T3.dept_name
