An alternate solution is to use a correlated subquery, as @Ray Booysen shows:
SELECT A.*, (SELECT COUNT.

BY A.ID, A.Name;
This outputs one row per row of A, with the count of matching B's.

From a high-level, what you need to do is tell the column that you will render the column on a per row basis.

If you have those, then adding another index on state_id is unnecessary as the first index that a simple search by state_id or slug or both will use one of the indices.)
Any decent optimizer will see something interesting.....
