### Question
What is the description, code and the corresponding count of each service type?

### SQL
SELECT T1.Service_Type_Description ,  T2.Service_Type_Code ,  COUNT(*) FROM Ref_Service_Types AS T1 JOIN Services AS T2 ON T1.Service_Type_Code  =  T2.Service_Type_Code GROUP BY T2.Service_Type_Code
