The Influence of International Migration on Demographic Aging in Sending Regions
Quick fact
In many sending regions, international out-migration removes a significant proportion of young adults (typically aged 20-40), which can increase the median age and reduce the working-age population, sometimes making the region age faster than even national or natural trends would predict.
Why this is interesting
You've seen headlines about countries growing older, but what if the aging of a region is quietly accelerated by the people who leave it, not just by those who stay?
