Population Projection of Ibaraki Municipalities Affected by the Great East Japan Earthquake

Abstract

In the area stricken by the Great East Japan Earthquake, emigration has occurred due to housing damage, industrial damage, and damage caused by rumors. In Ibaraki Prefecture, the extent of damage differs across 44 municipalities. The gap between the decrease in population and the increase in aging seems to have expanded. In this research, the degrees of acceleration in population decrease and aging have been measured by performing and comparing future population estimates before and after the Great East Japan Earthquake through the cohort component method.
