This article explores the coverage of labour migration in four national questionnaires in South Africa - the Project for Statistics on Living Standards and Development (1993), the National Census (1996 and 2001), the October Household Surveys (1995-9) and the Labour Force Survey (2000-1). Internal labour migration has been an integral part of South Africa's history and economic development. Whether this migration is changing, and how this will affect the rural household's access to resources, are surely important questions to be examined both now and in the future. A comprehensive investigation requires not only specific case study analysis, but also analysis of nationally representative data on households and the individuals who are part of these households, whether as resident or absent household members. Official household surveys in South Africa have been modified and revised over the years to improve the quality of information collected on individuals, households and their access to resources. However, questions of labour migration have received little attention in these revisions. Rather, the quality and quantity of information collected on migration and labour migrants specifically have declined such that in current sources of national data, the Labour Force Survey (2000-1) and the Census (2001), labour migrants are all but invisible.
