How much would reduced emigration mitigate ageing in Norway?

Population ageing is a topic of great concern in many countries. To counteract the negative effects ageing, increased fertility or immigration are often proposed as demographic remedies. Changed emigration is, however, rarely mentioned. We explore whether reduced could mitigate country like Norway. Using cohort-component methods, we create hypothetical future scenarios with lower rates, and present (prospective) old-age dependency ratios, population growth shares immigrants. also estimate howmuch immigrationwould have to change yield same effects. In different scenarios, for total subgroups, while taking into account that natives will entail return migration. Our results show even dramatic 50% decrease annual would only slightly, by lowering ratio 2060 from 0.54 0.52. This corresponds anti-ageing effect 15% higher fertility, one-quarter extra child per woman.
