Not sure precisely what you are asking, but the structure of your code suggests to me that you might want an OUTPUT statement before your END statement in your DO loop.

Here is a sketch of a typical data step;
Looping is implicit and there is an implicit execution of an OUTPUT before the run (one for each input obs read).
You did this, which is perfectly valid.
Read many write one. There is still one implicit output.
Since you said that something was missing, I thought you might want.
write each time you read by using an explicit OUTPUT;

Why there is only one obs per header record output to the data set instead of outputting all obs?
Because you read the entire household in one pass of the data step.
Since you are only keeping household level variables why would you want it to output more than one observation per household?
