Hi,I have the data above and ultimately need the following calculations to get the final output:

Calculations:

             All                                                                                                  Public                                                                                                      Private

vax 1  ((SUM OF ENROLLMENT- sum of vaxA)/sum of enrollment)*100      (( SUM OF ENROLLMENT FOR PUBLIC ONLY-sum of vaxA for public only)/sum of enrollment for public only)*100          ((SUM OF ENROLLMENT FOR PRIVATE ONLY-sum of vaxA for private only)/sum of enrollment for private only)*100

vax 2   ((SUM OF ENROLLMENT - sum of vaxB)/sum of enrollment)*100       ((SUM OF ENROLLMENT FOR PUBLIC ONLY - sum of vaxB for public only)/sum of enrollment for public only)*100          (SUM OF ENROLLMENT FOR PRIVATE ONLY - sum of vaxB for private only)/sum of enrollment for private only)*100

Final Output:

           All       Public       Private

vaxA  9.0%   10.0%      7.0%

vaxB  15.0%   18.0%      9.0%

Thank you!

1. Aggregate numbers (Enrollment, VaxA/B) by School type

2. Calculate percentages. 

3. Transpose to desired structure.

It is very convenient for SQL.

data HAVE;
 input COUNTY $ SCHOOL $ 	ENROLLMENT 	VAXA 	VAXB 	SCHOOLTYPE $ ;
cards;
countyA 	littlet 	50 	48 	45 	private 	  	  	  	 
countyA 	happyda 	100 	88 	77 	public 	  	  	  	 
countyA 	playtim 	25 	22 	23 	private 	  	  	  	 
countyB 	busybee 	23 	22 	21 	public 	  	  	  	 
countyB 	childti 	27 	25 	25 	public
;
run;
proc sql;
select 'vaxA' label='#',
 (select sum(vaxA)/sum(ENROLLMENT) from have) as All format=percent7.2,
 (select sum(vaxA)/sum(ENROLLMENT) from have where SCHOOLTYPE='public') as public format=percent7.2,
 (select sum(vaxA)/sum(ENROLLMENT) from have where SCHOOLTYPE='private') as private format=percent7.2
from have(obs=1)
union 
select 'vaxB' label='#',
 (select sum(vaxB)/sum(ENROLLMENT) from have) as All format=percent7.2,
 (select sum(vaxB)/sum(ENROLLMENT) from have where SCHOOLTYPE='public') as public format=percent7.2,
 (select sum(vaxB)/sum(ENROLLMENT) from have where SCHOOLTYPE='private') as private format=percent7.2
from have(obs=1)
;
quit;

Appreciate your help everyone. I tried the code and realized I'd forgotten(!!) an important step which is summing the enrollment and then subtracting for example the sum of vaxA, etc. I edited the original post and used CAPS to indicate which portions I edited. Forgive my oversight. Thank you for your help.
