SAS FAQ #24: Data as percentages in SAS

Question:

How do I convert the levels of a SAS variable to percentages?

Answer:

Use PROC RANK. In the following example, the variable PRCNTS is created to contain the percentage values for the ranks assigned to the values of the original variable VAR1. Both variables will be contained in the output dataset ROUT. Note that it is the P option in the PROC RANK statement that directs SAS to divide each rank by the number of nonmissing observations and multiply by 100 to get a percentage.

PROC RANK DATA=insds P OUT = rout ;
VAR var1 ;
RANKS prcnts ;
