[dba-SQLServer] SQL Server Pivot

I have a bunch of columns that break out ages into bands.  For example:

Presence_of_adults_age_65_74_specific
Presence_of_adults_age_55_64_specific
Presence_of_adults_age_45_54_specific
etc

Each column has codes 1,2,3

I need counts of each column, for each value

column	Cnt1	Cnt2	Cnt3
65_74		45	3	23
55_64		103	48	211
45_54		20	1	49

etc

I think the Pivot statement is going to do that for me but I can't seem to
wrap my mind around the syntax.  Can anyone point me to a web page that
clearly explains this or simply write a SQL statement that does this?

Thanks
