Notes
The questionnaires asked what language each person spoke most often at home. Household and personal questionnaires then included questions on whether the person spoke more than one language at home and, if so, what was the next most often spoken language. A coding list of languages was compiled, including the 11 official languages as well as other languages which are relatively commonly spoken in South Africa. Interviewers were instructed: ‘For babies, write down the home language of their parents. (If the parents have different home languages, write down the mother’s home language).’
