Enterprise/Establishment Survey [en/oth]

working conditions [3.6]
The survey was part of the survey work of the Regional Programme on Enterprise Development (RPED), organised by the World Bank and funded by the Swedish, French, Belgian, UK, Canadian and Dutch governments. The data is from the manufacturing sector of five African countries, Cameroon, Ghana, Kenya, Zambia and Zimbabwe.
Africa
Cameroon, Ghana, Kenya, Zambia, Zimbabwe
Units of analysis in the survey are enterprises in the selected countries
The universe of interest here is firms and their staff in the selected countries
Sample survey data [ssd]
The dataset includes measures of both physical and human capital in the firms in the selected countries
Face-to-face [f2f]
The questionnaire collected data at the level of the firm - called firm level data in the exposition that follows and also data at the worker level (individual level data). At the firm level data on the outputs, costs and the details of the labour force of the firm were collected. Within each firm up to 10 workers were then interviewed and information collected on their educational background, their training and earnings.
