Full text not available from this repository.Abstract
We assess the potential impact of international migration on population ageing in Asian countries by estimating replacement migration for the period 2022-2050.
This open data deposit contains the code (R-scripts) and the datasets (csv-files) for the replacement migration scenarios and a zero-migration scenario:
Constant chronological old-age dependency ratio (Constant OADR scenario)
Constant prospective old-age dependency ratio (Constant POADR scenario)
Constant chronological working-age population (Constant WA scenario)
Constant prospective working-age population (Constant PWA scenario)
Zero-migration (ZM scenario)
Countries included in the analysis: Armenia, China, Georgia, Hong Kong, Japan, Macao, North Korea, Singapore, South Korea, Taiwan, Thailand.
Please note that for Armenia and Hong Kong (2023) and Georgia (2024) later baseline years are applied due to the UN country-specific assumptions on post-Covid-19 mortality.

Datasets
The datasets contain the key information on population size, the relevant indicators (OADR, POADR, WA, PWA) and replacement migration volumes and rates by country and year. Please see readme_datasets.txt for detailed information.
