{"title":"Can resident registration expiration statistics due to death be used for near-real-time mortality tracking? A validation study using 2023 data from Korea.","authors":"Jin-Hwan Kim","doi":"10.4178/epih.e2025042","DOIUrl":"10.4178/epih.e2025042","url":null,"abstract":"<p><strong>Objectives: </strong>Real-time mortality tracking is essential for public health surveillance, especially during emergencies such as the coronavirus disease 2019 (COVID-19) pandemic. In Korea, delayed availability of vital statistics (VS) data has hindered timely mortality monitoring.

The analysis was conducted in 3 stages: comparing overall mortality counts, analyzing county-level distributions, and assessing equivalence through correlation analyses, scatter plots, and density plots.</p><p><strong>Results: </strong>NAD showed strong agreement with VS at the national level, reporting only 0.4% more deaths overall (0.2% for male, 0.6% for female). Notable differences were observed in early childhood mortality, with NAD showing 16.8% fewer deaths for neonates (age 0) and 14.8% more for ages 1-4, as well as in monthly variations (5-9%).
