Abstract

Microsimulation model has aimed to simulate the impact of policy at the level of individual and household. Recently, microsimulation model has been widely accepted in OECD countries for evaluating their economic and social policies. For improving the availability of microsimulation model, the population data which shows good accordance with the official statistics should be required. In this paper, we generate Korean synthetic populations by using the iterative proportional updating method. For the validation of Korean synthetic populations, we compute the difference between the generated synthetic populations and the summary table of Korean census. Then, we confirm that it shows good accordance with the summary table.

마이크로시뮬레이션 모델은 거시적 수준의 인구, 사회, 경제 변화를 각 개인과 가구 단위의 미시적 수준의 사건들로부터 기술하고자 하는 것을 목적으로 하며, 최근 OECD 국가들을 중심으로 정책 시뮬레이션 도구로서 많은 관심을 받고 있다. 마이크로시뮬레이션 모델의 활용도를 높이기 위해서는 해당 국가의 인구 구조를 잘 반영하는 인구 데이터가 필요한데, 우리는 반복비례갱신 (iterative proportional updating) 방법을 이용하여 한국 가상 인구를 생성하였다. 생성된 가상 인구 데이터의 검증을 위하여 인구센서스 집계 결과와의 오차를 계산하였으며, 가구와 인구 모두에 대해서 실제 집계 결과와 작은 오차를 보이는 것을 확인하였다.
