Mortality data is collected through various methods:
Vital Registration Systems: These include birth and death certificates that record official cause of death. Surveillance Systems: Health institutions and agencies monitor and report deaths due to specific diseases. Surveys and Censuses: Large-scale surveys and national censuses provide demographic and health-related data. Hospitals and Clinics: Health facilities often have records of deaths and related health information. Verbal Autopsies: In areas lacking formal registration systems, interviews with family members can help determine probable causes of death.
