Decode and Ranges?

Hi,

Here is what I am trying to do:

In one SQL statement using Decode ( or another function you might suggest), validate a numeric range so . . .

If the row value is between 6 and 10 display a count of records.

Psydo -code:
Select gender_cd,
count(decode(round(months_between(birth_dt,sysdate)/12),between 6 and 10, total count))) "Age 6-10"
from members
where . . . . .

Result would look like this:

              Age 6-10   Age 11-15
Males          5               10
Females      6                22
