Which countries have declining populations?
RE
Obsolete video going only to 2019. Serbia has 25% increase in deaths in 2021 over 2020 for January to October.
Portugal was one of the lowest birth rates in EU and has over 7% lower births for September 2021 over September 2020. Compared to September 2019 it's closer to 10%.
This is just getting started. Expect about 50% more death and 15-20% lower births in 2022 than 2019 for western countries.
