Information on income alone, or on health alone, provides a less complete picture. Better health can lead to higher income, and higher income can lead to better health, so that we cannot fully understand the dynamics of either process without understanding both. Much of the research on international health and income has focused on the cross-country relationships between population health and national income. Starting from Preston (1975, 1980), these relationships have been used to investigate the causes of mortality decline, particularly the relative roles of income and of medical knowledge. And data on adult height have been used to investigate the causes of the historical decline in mortality, see in particular Fogel (1997, 2004), Floud, Wachter, and Gregory (1990), and Steckel (1995). 2009-07-01T00:00:00Z http://hdl.handle.net/11090/807 Migration: Analysis of the NIDS Wave 1 Dataset Posel, Dorrit This paper investigates measures of migration captured in the National Income Dynamics Study (NIDS), and it compares these measures, and how information is collected, with other household surveys conducted in South Africa. The paper is divided into five sections. The first section describes households with non-resident (or absent) household members. A key reason why individuals may be absent from a household for much of the year is because they are migrant workers. The second section therefore looks specifically at households which report migrant workers as absent household members. Section three describes inter-household transfers received by households, and it considers the relationship between households that report transfers and households that report migrant workers. The fourth section investigates migration more generally as the movement of people across space and the change in an individual’s place of residence. The last section summarises the main similarities and differences between NIDS and other household surveys in South Africa. 2009-07-01T00:00:00Z
