List of countries by age at first marriage

This is a list of countries by age at first marriage. This list is current from contemporary surveys and does not treat the topic in history. Currency of information varies by country. Because the age distribution of people at first marriage is skewed with a longer tail towards older ages, the majority of people marry before the average age of first marriage. The median age is a more precise representation of when the majority of people marry; for most reporting sources, however, only the average age at marriage is reported.

Note: the reported age for these countries is the median, not the mean (average). All countries in italics have their data in the mean and not the median.
