The percentage of ever married women and men in the age group 15 to 19 years refers to the percentage of women and men in that age group who are currently married and those who had been married in the past and are currently divorced or widowed. These percentages are derived from census data on the population classified by their current marital status, sex and age group. The indicator is a useful measure of the prevalence of marriage at young ages.
The singulate mean age at marriage is an estimate of the average number of years lived prior to first marriage by a hypothetical cohort, if they marry before age 50. The singulate mean age at marriage is calculated on the basis of a single census or survey according to procedures described by Hajnal in « Age at marriage and proportions marrying » (Population Studies, vol. 7, No. 2. 1953). The singulate mean age at marriage is a summary measure of differences in the timing of first marriage among women and men.
