I want to display the count from a single collection called Faculty. but the count should come as taxonomy Department wise wise. ex: I have 10 entries in Faculty collection, and the department taxonomy selected as CS department have 5 entries and ME department has 5 entries it should display like

CS Faculty  count is 5
 and 
ME Faculty count is 5

My code is like:

{{ collection:faculty taxonomy:departments="{{title}}" }}
        {{count}}
        {{ /collection:faculty }}

Please help me to get the count
