^c $1.25 at 2005 international prices. Data are from primary household survey data.

^d Measured as the total number of students in the last grade of primary school, minus the number of repeaters in that grade, divided the total number of students of official graduation age. For values that were >100%, these were manually changed to 100%. Data are obtained from national statistical offices submitted to the UNESCO Institute for Statistics (UIS), with the UIS sometimes generating estimates and imputing missing data

^e Measured as the number of women who die from pregnancy-related causes while pregnant or within 42 days or pregnancy termination per 100,000 live births. These are national estimates.

^f Definitions of ‘safe’ and ‘basic’ as determined by the use of ‘improved’ technologies defined by the WHO/UNICEF Joint Monitoring Programme (JMP)
