Early Childbearing and Child Marriage: An Update

Area of Science:

• Demography
• Public Health
• Sociology

Background:

• Child marriage is often linked to early childbearing, but recent data on the marital context of births to adolescent mothers is scarce.
• Understanding the relationship between marriage and adolescent childbearing is crucial for policy development.
• Geographical and developmental variations in this relationship require further investigation.

Purpose of the Study:

• To estimate the global, regional, and national proportions of first births to mothers under 18 that occur within marriage.
• To analyze trends in the marital context of adolescent childbearing over the past two decades.
• To explore the sequencing of child marriage and childbearing across different countries.

Main Methods:

• Utilized survey and vital registration data encompassing approximately 95% of global births to mothers under 18.
• Calculated the share of first births occurring within marriage at various geographical scales (global, regional, national).
• Examined changes in this share over the past 20 years and the timing of marriage relative to birth.

Main Results:

• Over half of births to mothers under 18 globally occur in sub-Saharan Africa, a proportion expected to increase.
• Globally, 76% of first births to mothers under 18 occur within marriage, with significant regional disparities.
• The proportion of such births within marriage has decreased in most countries over two decades, with notable exceptions.

Conclusions:

• Adolescent childbearing is predominantly within marriage, particularly in sub-Saharan Africa, highlighting the need for targeted interventions.
• While the trend shows a decline in births within marriage for adolescent mothers, regional variations and exceptions persist.
• The sequence of child marriage and early childbearing is not uniform, necessitating context-specific strategies to address adolescent pregnancy and child marriage.
