4대 공적연금의 연령별 사망률 데이터 구축에 관한 연구

Abstract

In this study, we aimed to address the issue of not reflecting the characteristics of each public pension system by constructing data on mortality rates by age group for the four public pensions, which had not been established before. To do this, we utilized NHID from National Health Insurance Service and estimated values from statistical yearbooks of the four public pension agencies, along with data obtained through information disclosure requests. Successfully, we constructed mortality rate data by age group. During the data construction process, issues such as data integration and correction arose, which were addressed using statistical methods. Using the constructed data, we compared the life tables of five groups: subscribers and recipients of the four major public pensions, and non-subscribers, for the years 2011 to 2018, and compared life expectancies. The comparison results showed that overall, the order of average life expectancy was non-participants ≤ National Pension ≤ Government employee Pension ≤ Military Pension ≤ Teachers Pension participants and recipients, with significant differences observed. This study is the first in Korea to construct mortality rate data by age group for the four public pensions, which could serve as a foundational dataset for new fiscal projections of public pensions, contributing to addressing issues related to public pension reform.
