sql - Count records for every month in a year

I have a table with total no of 1000 records in it.It has the following structure:

EMP_ID EMP_NAME PHONE_NO   ARR_DATE
1        A        545454 2012/03/12

I want to calculate no of records for every month in year-2012

Is there any way that should solve my issue in a single shot?

I tried:

select count(*) 
from table_emp 
where year(ARR_DATE) = '2012' and month(ARR_DATE) = '01'
