The “Global Collaboratory on the History of Labour Relations” has developed a “Taxonomy of Labour Relations” and a method to collect data on labor relations that comprises all kinds of work, including work for the household and homestead, the family firm or farm, and self-employment in the so-called informal sector. In this article, we explain this method and give an overview of the results of data so far collected in various parts of the world, offering a comparative context for the data on sub-Saharan Africa.
