NEGATIVE POPULATION GROWTH

The latest data from the Population Reference Bureau shows that there are twenty countries in the world with negative or zero natural population growth. This is unprecedented in history!
This negative or zero natural population growth means that these countries have more deaths than births or an even number of deaths and births; this figure does not include the impacts of immigration or emigration. Even including immigration over emigration, only one of the twenty countries (Austria) is expected to grow between 2006 and 2050.
The country with the highest decrease in the natural birth rate is Ukraine, with a natural decrease of 0.8% each year. Ukraine is expected to lose 28% of their population between now and 2050 (from 46.8 million now to 33.4 million in 2050).
Russia and Belarus follow close behind at a 0.6% natural decrease and Russia will lose 22% of their population by 2050 – that is a loss of more than 30 million people (from 142.3 million today to 110.3 million in 2050).
Japan is the only non-European country in the list and it has a 0% natural birth increase and is expected to lose 21% of its population by 2050 (shrinking from 127.8 million to a mere 100.6 million in 2050). The streets of Tokyo won’t be as crowded in a few decades as they are today!
