Dear all

I am using the panel dataset of South African National Income Dynamics Survey (NIDS) - waves 1 to 5.
I am wanting to create a Binary Variable for whether a child (restricted to age 6 to 17) has a disability or not.
As simple as this should be, the problem is that the questionnaires were split up in such a way that the child questionnaire is only between ages 0 to 15.
The adult questionnaire thus has people older than 15.
I do have a variable for 'disability' arising from each questionnaire, but i now what to make one for the ages 6 to 17.

My question then is: how do you combine the two variables from the questionnaire into one?

Kind regards
Sophie
