Child marriage is a violation of human rights, but is all too common

Marriage before the age of 18 is a fundamental violation of human rights. Many factors interact to place a girl at risk of marriage, including poverty, the perception that marriage will provide ‘protection’, family honour, social norms, customary or religious laws that condone the practice, an inadequate legislative framework and the state of a country’s civil registration system. Child marriage often compromises a girl’s development by resulting in early pregnancy and social isolation, interrupting her schooling, limiting her opportunities for career and vocational advancement and placing her at increased risk of domestic violence. Child marriage also affects boys, but to a lesser degree than girls.

Cohabitation – when a couple lives ‘in union’, as if married – raises the same human rights concerns as marriage. When a girl lives with a man and takes on the role of his caregiver, the assumption is often that she has become an adult, even if she has not yet reached the age of 18. Additional concerns due to the informality of the relationship – in terms of inheritance, citizenship and social recognition, for example – may make girls in informal unions vulnerable in different ways than girls who are married.

The issue of child marriage is addressed in a number of international conventions and agreements. The Convention on the Elimination of All Forms of Discrimination against Women, for example, covers the right to protection from child marriage in article 16, which states: “The betrothal and the marriage of a child shall have no legal effect, and all necessary action, including legislation, shall be taken to specify a minimum age for marriage….” The right to ‘free and full’ consent to marriage is recognized in the Universal Declaration of Human Rights, which says that consent cannot be ‘free and full’ when one of the parties involved is not sufficiently mature to make an informed decision about a life partner. Although marriage is not mentioned directly in the Convention on the Rights of the Child, child marriage is linked to other rights – such as the right to freedom of expression, the right to protection from all forms of abuse, and the right to be protected from harmful traditional practices – and is frequently addressed by the Committee on the Rights of the Child. Other international agreements related to child marriage are the Convention on Consent to Marriage, Minimum Age for Marriage and Registration of Marriages, the African Charter on the Rights and Welfare of the Child and the Protocol to the African Charter on Human and People’s Rights on the Rights of Women in Africa.

CHILD MARRIAGE AMONG GIRLS

Across the globe, levels of child marriage are highest in sub-Saharan Africa, where around 4 in 10 young women were married before age 18, followed by South Asia, where 3 in 10 were married before age 18. Lower levels of child marriage are found in Latin America and Caribbean (25 per cent), the Middle East and North Africa (17 per cent), and Eastern Europe and Central Asia (11 per cent).

The prevalence of child marriage is decreasing globally, with the most progress in the past decade seen in South Asia, where a girl’s risk of marrying in childhood has dropped by more than a third, from nearly 50 per cent to 30 per cent.

Still, the total number of girls married in childhood stands at 12 million per year, and progress must be significantly accelerated in order to end the practice by 2030 – the target set out in the Sustainable Development Goals. Without further acceleration, more than 150 million additional girls will marry before their 18th birthday by 2030.

MARRIED ADOLESCENTS

Globally, about one in six adolescent girls (aged 15 to 19) are currently married or in union. West and Central Africa has the highest proportion of married adolescents (27 per cent), followed by Eastern and Southern Africa (20 per cent) and the Middle East and North Africa (13 per cent).

CHILD MARRIAGE AMONG BOYS

Child marriage affects girls in far greater numbers than boys, with the prevalence among boys about one fifth the level among girls globally. Available data confirm that in every region boys are less likely than girls to marry before age 18, though there are countries in which boys marrying before age 18 is not uncommon. However, data on the number of boys affected by child marriage are limited, making it difficult to draw definitive conclusions on its status and progress.

Differential effects of young maternal age on child growth

Nov 17, 2016

The association of early maternal birthing age with smaller children has been widely observed. However, it is unclear if this is due to confounding by factors such as socioeconomic status, or the age at which child growth restriction first occurs. This paper examines the effect of early maternal birthing age on the first-born child’s height-for-age in a sample of developing countries in Africa, Asia, and Latin America.

Risk factors associated with the practice of child marriage among Roma girls in Serbia

Feb 3, 2016

Relatively little research on the issue of child marriage has been conducted in European countries where the overall prevalence of child marriage is relatively low, but relatively high among marginalized ethnic subgroups. The purpose of this study is to assess the risk factors associated with the practice of child marriage among females living in Roma settlements in Serbia and among the general population and to explore the inter-relationship
between child marriage and school enrollment decisions.

Ending Child Marriage: Progress and prospects

Jul 22, 2014

Ending child marriage will help break the intergenerational cycle of poverty by allowing girls and women to participate more fully in society. Empowered and educated girls are better able to nourish and care for their children, leading to healthier, smaller families. When girls are allowed to be girls, everybody wins. This brochure explores the data and statistics behind those stories: the current situation of child marriage, lifelong – sometimes intergenerational – consequences, progress to date and prospects.

Notes on the Data

DATA SOURCES

The term ‘child marriage’ is used to refer to both formal marriages and informal unions in which a girl or boy lives with a partner as if married before the age of 18. An informal union is one in which a couple live together for some time, intending to have a lasting relationship, but do not have a formal civil or religious ceremony. The main sources of such data are national censuses and national household surveys, predominantly the Multiple Indicator Cluster Surveys (MICS) and Demographic and Health Surveys (DHS).

MAIN INDICATORS

In 2003, UNICEF and partners agreed to focus on five indicators related to child marriage:

  • Percentage of women 20 to 49 first married or in union by age 15 and 18, by age group
  • Percentage of girls 15 to 19 years of age currently married or in union
  • Spousal age difference
  • Percentage of women currently in a polygynous union, by age groups
  • Percentage of ever-married women who were directly involved in the choice of their first husband or partner.

Many countries also collect data on the marital status and age at first marriage for boys and men, thereby allowing a comparison of gender differentials related to child marriage.

INTERPRETING THE DATA

The context and indicators related to child marriage and cohabitation can be approached through the examination of age groups. One approach is to consider all women in a society. Another would be to observe the situation of girls aged 15 to 19 to determine the number of girls currently married or in union and the characteristics associated with that age group. However, gauging how many of those girls will be married or in union by their 18th birthday is more complex because many have not yet reached the age of 18. Looking at the group of women 20 to 24 years old is simpler and allows for the inclusion of all girls who were married or in union by age 18 within the closest time period for which complete data are available.
