Transposing individuals dataset into a household dataset

Demographer — Fri, 26 Feb 2021 07:29:02 GMT

Hi,

I have a dataset containing individual data that looks like this. The variable HHID identify household, while Indiv_ID is the unique identifier for individuals:

HHID	Indiv_ID	reln_HH	sex	age
Q1V1501011101	1	Married child	Male	25
Q1V1501011101	2	Spouse of married child	Female	28
Q1V1501011101	3	Self	Male	52
Q1V1501011102	4	Self	Female	63
Q1V1501011102	5	Grandchild	Female	2

I want to transpose it into a household dataset in which each line is a household. It should look like this.

HHID

Indiv_ID1

reln_HH1

sex1

age1

Indiv_ID2

reln_HH2

sex2

age2

Indiv_ID3

reln_HH3

sex3

age3

Q1V1501011101

Married child

Male

Spouse of married child

Female

Self

Male

Q1V1501011102

Self

Female

Grandchild

Female

I did some attempts with proc tranpose but it always gives something very different from what I want.

I don't think proc transpose is well suited to the "block transpose" task you want to do.

This program will likely do what you want.

data have;
  input HHID $13. Indiv_ID	reln_HH	&$24.   sex :$6.	age;
datalines;
Q1V1501011101	1	Married child	Male	25
Q1V1501011101	2	Spouse of married child 	Female	28
Q1V1501011101	3	Self	Male	52
Q1V1501011102	4	Self	Female	23
Q1V1501011102	5	Grandchild	Female	2
run;

filename tmp temp ;
data need (drop=_:) ;
  do seq=1 by 1 until (last.hhid);
    set have end=end_of_have;
    by hhid;
    output;
  end;

  retain _maxseq .;
  _maxseq=max(_maxseq,seq);

  if end_of_have;
  file tmp;
  do _s=1 to _maxseq;
    put 'need (where=(seq=' _s ') rename=(indiv_id=indiv_id' _s 'reln_hh=reln_hh' _s 'sex=sex' _s 'age=age' _s '))' ;
  end;
run;

data want;
  merge
    %include tmp / source2 ;
  ;
  by hhid;
run;

Take a look at dataset NEED to see how the DATA WANT step works.

Posting data in usable form and the code you have makes it easier to provide a useful answer.

Why do you need to transpose the data from long to wide format? You may have noticed, that in almost all other discussion in the community using data in a long format is recommended. Or do you want a report?

Since family sizes vary so much you are going to have some fun using sex1, sex2, sex3, sex4 ... sex25 in any form of analysis. When it comes time to do anything with "adults" or "children" you will spend a LOT of time futzing around with which is which for each family.

Please, in some detail, describe what you expect to do with that data set once you have made it "wide" like that. Specific analysis or report examples would be nice.

If you want something for people to look at then a report such as

proc report data=have;
   columns hhid indiv_id,(rein_hh sex age);
   define hhid / group;
   define indiv_id/ across;
   define rein_hh /display;
   define sex/display;
   define age/display max;
run;

might be helpful.

The way you have shown the output for HHID Q1V1501011101 and Q1V1501011102 makes me suspect that you actually want two variables, one with Q1V15010111 and a second with 01 or 02 (and similar).
