Death registration is a key component of a vital statistical system because it provides basic data for population planning, public health evaluation, and evidence-based policymaking. However, the quality of death records in different countries shows significant differences, especially between developed and developing countries. This study aims to examine the death registration system in Indonesia and developed countries, identify factors that affect the accuracy and completeness of mortality data, and examine the challenges and solutions for improving the Civil Registration and Vital Statistics (CRVS) system. The research was conducted through a qualitative descriptive approach based on literature studies using national and international official reports such as WHO, UNSD, BPS, as well as various relevant scientific articles. The results of the study show that developed countries have a recording completeness rate of more than 95%, supported by integrated digital systems, strong reporting obligations, and adequate medical personnel. On the other hand, Indonesia faces obstacles in the form of low reporting of household deaths, limited medical verification, suboptimal data integration between agencies, and uneven technological infrastructure. Socio-economic, geographical, public awareness, and administrative weaknesses also affect the low quality of recording. This study concludes that improvement efforts need to include digitizing the CRVS system, increasing training of health workers, strengthening mandatory reporting regulations, public education, and integration of data across institutions. Lessons from the best practices of developed countries show that institutional reform and consistency in the implementation of digitalization are key to improving the quality of national mortality statistics.
