1)      Number of women (or men) age 15-24 who had sexual intercourse before age 15 (women: v012 in 15:24 & v531 in 1:14; men: mv012 in 15:24 & mv531 in 1:14)

2)      Number of women (or men) age 18-24 who had sexual intercourse before age 18 (women: v012 in 18:24 & v531 in 1:17; men: mv012 in 18:24 & mv531 in 1:17)

 

Denominator:

a)       Number of women (or men) age 15-24 (women: v012 in 15:24; men: mv012 in 15:24)

Calculation

 

The numerator divided by the denominator, expressed as a percentage.

 

Handling of Missing Values

 

Women and men with unknown and missing ages at first sexual intercourse are excluded from both the denominator and the numerators.

 

Notes and Considerations

 

Age at first sexual intercourse is reported as age in completed years.

Presented by age group, percentages are not calculated where the youngest member of the cohort defined by the age group has not yet reached the specified age at which first sexual intercourse occurred. For example, percentages for the cohort of women 20-24 at the time of the survey will not be calculated for age group categories 15-17 or 15-19 because some women in those age groups who have never had intercourse could still have their first intercourse before aging out of their age group categories.
