AGE AT FIRST MARRIAGEStatistics: Percent Distribution by Years of Age at First Marriage, Total, <strong>and</strong> According toCurrent Age GroupDefinitionPercents of women who first married or lived with a man before attaining the specified ages.A. Coverage: Women of all marital statuses.B. Numerator: Number of women whose first marriage or consensual union occurred before theyattained the specified age group.C. Denominator: Total number of women, including those who have never been married or in aconsensual union.CalculationA. Age at first marriage or first union: Difference between date when women began living with firsthusb<strong>and</strong> or consensual partner <strong>and</strong> date of birth of woman in completed single years (in the <strong>DHS</strong>st<strong>and</strong>ard recode, this difference is already calculated—V511).B. Numerators: Number of women below specified age categories. Women who have never marriednor lived in a consensual union are included in a separate category.C. Denominator is the number of women of all marital statuses. Ever-married sample denominatorsare adjusted by the all women factors.D. Numerators for each age group category are divided by the same denominator <strong>and</strong> multiplied by100 to obtain percentages.H<strong>and</strong>ling of Missing ValuesNot applicable—birth dates of women <strong>and</strong> ages at first marriage were imputed if missing.Notes <strong>and</strong> ConsiderationsPercentages add up to 100 percent.Percents are not calculated for the age-at-first-marriage categories by cohorts of women where theyoungest member of the cohort has not yet completed the oldest age of the category. (For example,percents for the cohort of women 15–19 at the time of the survey will not be calculated for age categories18, 20, 22, <strong>and</strong> 25 because some women who have never been married are still below those ages <strong>and</strong>could still marry or start to live in a consensual union before reaching those age categories).Guide to <strong>DHS</strong> Statistics 69 Updated September 2006
