Overview

The term spread from Hiroya Masuda’s 2014 report in Japan. In Korea, Lee Sang-ho (KEIS, 2016) proposed the extinction risk index = women aged 20–39 ÷ people aged 65+; below 0.5 signals risk. The Ministry of the Interior designated 89 depopulation areas in October 2021, backed by a 2023 special act and fund. See low fertility.

Frequently asked questions

What does 0.5 mean?
