Question

Is it possible to create a data set with new rows proportional to population density? For instance, if I have population density of a certain state, is it possible to create empty rows where the number of rows are proportional to its population density?

zip   density
75001 2551
75002 944
75006 2625
75007 4209
75009 51

Answer 1

I think you’re looking for something like this…

data dat;
input 
 zip 
 density;
cards; 
75001 2551
75002 944
75006 2625
75007 4209
75009 51
run; 



data new; 
  set dat; 
  by zip;
  if first.zip then do; 
    do i= 1 to density;
        output; 
    end; 
  end; 
Run;
