Something like:

select first_name || last_name as wholename, count(*) as ccount
from club_members
group by 1
into temp tccount;

select count(wholename), ccount
from tccount
group by 2
order by 2;

Or you could do something like

select count(wholename), ccount
from (
select first_name || last_name as wholename, count(*) as ccount
from club_members
group by 1
)
group by 2
order by 2;

Not tested either one.

Not sure how you're going to cope with students who aren't in any clubs.
