All these sample members, including children, are continuing sample members and will be re-interviewed in 2010 and in subsequent waves. After the fieldwork, the NIDS sample weights were adjusted to reflect the age-sex-race and provincial distributions of the 2008 mid-year population estimates produced by Stats SA. Of these 78.6% were classified as African, 14.8% as Coloured, 1.6% as Asian/Indian and 5.1% as white. When weighted up to population totals this represents 48 442 116 individuals from 13 722 918 households with the respective racial percentages being 79.4%, 8.9%, 2.6% and 9.1%.
