Hi, I'm working with South African survey data called NIDS wave 5. There's a household decision making variable which sites the personal identifier of the household decision maker as the answer. I am looking for a way for my code to take this personal identifier and then go and find that person in the survey and identify their gender. For example, if the answer for the household decision making variable is 321045 (which identifies a person in the sample) I need my code to go to person with ID 321045 and find their gender.
