Weddings and Marriage - Statistics & Facts
Child Marriages
Demographic data regarding married populations can also reveal social factors or customs that vary by region. For example, despite international conventions defining the minimum age of marriage at 18 years, child marriage remains a global problem. Some areas of the world are particularly impacted by this, most notably Africa, South Asia, and Central America. Niger has the highest rate of child marriage in the world. In this West African country, 75 percent of girls aged under 18 were married, with 36 percent of them under the age of 15 years.However, in terms of absolute numbers India had the largest number of child marriages, despite having a legal marriage age of 18 years. Additionally, the legal age in many countries is higher for males than for females; for example, by Nigerien law, females must be at least 15 years before marriage, whereas males must be 18. In Guinea, the legal ages are closer at 17 for females and 18 for males, however, 20 percent of young girls are married before the age of 15.
Gay and polygamous marriage
The right to marry is also not guaranteed to everyone in the same measure. Gay marriage is legal or recognized in relatively few countries worldwide, although a number do permit civil unions. As of 2022, 31 countries worldwide allow gay marriage nationwide or in some jurisdictions. Costa Rica became the latest country to have legalized same-sex marriage in 2020.Another factor which relates to laws and rights of marriages is polygamy, which is generally where one male has two or more wives (females taking multiple husbands is rare and prohibited in most religions). Polygamy is legal in 58 countries, most of which are found in Africa, the Middle East, and South Asia. It is estimated that approximately two percent of the world’s population are in a polygamous marriage, the highest rates of which are recorded in West Africa, particularly Burkina Faso and Mali, where 36 percent and 34 percent of people respectively live in a polygamous household as of 2019.
