Can we use the 'keep' statement for survey data in SAS to create subsets?

Hello,

Can one use the ‘keep’ statement to select variables of interest from a survey data (particularly BRFSS data) into a subset dataset?

The following is my SAS code.

Thank you

 Data BRFSS2018b3;
 Set BRFSS2018b;
 SEX=SEX1;
 keep IYEAR SEQNO _AGE80 _STSTR _psu _LLCPWT MEDCOST HLTHPLN1  EMPLOY1 INCOME2 _EDUCAG EMPLOY1  _RACE SEX;
;RUN;

Yes.

Basic response would be "try it an see".

Thank you so much for your prompt response.

My main concern was about the weights. So the weights are not affected as long as I am not creating a subset within a variable, right?

You need to include the weights for the correct downstream analysis.
