***Note: stonetj is right. Use ' ' to assign character values to your new variable AGEP_CLASS. Use the maximum length for your AGEP_CLASS, length AGEP_CLASS $13;

One more thing, if you want to calculate the mean of AGEP, use class statement instead of by statement. If you want to use by statement, you have to sort your data by migrant first before you are using proc means.;
