For countries where DHS data are used, it is the proportion giving birth in the year before the survey who are not married at the time of the survey. The most recent data for South Africa (1998) are considerably older than for other countries; more recent Demographic and Health Survey data (2003) were deemed unreliable by the implementing organizations. Turkey, Jordan, and Egypt DHS interviewed only ever-married women (all waves).
