o    The International Classification of Diseases (ICD) is used to standardize the coding of causes of death.
o    Information related to the place of death, and the age of death are also recorded.

• Marriage and Divorce Registration:
o    Provides insights into family structures, which can influence health behaviors and social support systems.
o    Information about age at marriage, and length of marriage are valuable.

• Adoption Registration:
o    Protects the legal rights of adopted individuals and their families.
o    These records are often confidential to protect the privacy of all parties involved.

• Stillbirth Registration:
o    This is a very important part of vital registration. Stillbirths give very valuable data concerning maternal and infant health.

Global Challenges and the Importance of CRVS Systems:
• Many low- and middle-income countries lack comprehensive CRVS systems, leading to significant data gaps.
• These gaps hinder efforts to monitor health trends, plan public health interventions, and ensure equitable access to services.
• The World Health Organization (WHO) and other international organizations are working to strengthen CRVS systems globally.
• The lack of registration of vital events can lead to "statistical invisibility," where vulnerable populations are excluded from planning and policy-making.

Case Study: The National Vital Statistics System (NVSS) in the United States (Expanded):
• The NVSS is a collaborative effort between the National Center for Health Statistics (NCHS) and state and local vital registration offices.
• It collects data on births, deaths, marriages, divorces, and fetal deaths.
• The NVSS uses standardized data collection forms and procedures to ensure data quality and comparability.
