Four data sources are used in this article. 1) The Cape Area Panel Study1 (Lam et al 2006) is a random sample of 4758 young adults aged 14-22 in 2002 who live in the Cape Town Metropolitan Area. These young adults were interviewed first in 2002. A subset of 1360 young adults were reinterviewed in 2003, with the remainder reinterviewed in 2004, and all were reinterviewed in 2005. This paper utilizes information on annual partners collected in 2002 and 2005. 2) DHS data: this refers to the 1998 South Africa, 2003 Kenya, 2004 Lesotho, 2004 Malawi, 2003 Tanzania, and 2005/06 Zimbabwe DHS surveys.

Table 1 provides summary statistics from these data. 3) Labour Force Survey: This is a twice yearly rotating panel of households in South Africa designed to examine employment status and demographic variables across South Africa, with sampling done from 1996 census blocks.
