Although the October Household Survey provides employment data for 1994-1997, including the informal sector, the sectoral disaggregation is far from satisfactory. Indeed the employment is disaggregated at 1-digit ISIC level only, whereas more detailed statistics are often needed to carry out empirical research. For a definition and description of these manufacturing groups, see the explanation of the classifications. Export and import data are from DTI based on Stats South Africa. Monthly wages and salaries are from Stats SA statistical releases.
Local productivity is defined as the ratio of gross output to employment.
