World population to hit 8bn in 2023, says new UN survey
By contrast, all European countries now languish with fertility rates below replacement level, meaning that populations will inexorably decline without large-scale immigration.
“In some countries with low levels of fertility and ageing populations ... a net inflow of migrants has been the primary source of population growth and in some cases has averted a decline in population size,” noted John Wilmoth, director of the UN’s population division.
Eastern Europe is likely to be particularly badly affected by population trends, with numbers likely to fall more than 15% in Bulgaria, Croatia, Latvia, Lithuania, Poland, Republic of Moldova, Romania, Serbia and Ukraine. The UN study also found that there are more men than women globally (102 men for every 100 women), and that the number of people over 60 will top 1 billion in 2018 – and 2 billion by 2050. Children under 15 years make up about one quarter of the world’s inhabitants.
The median age of the world’s population is 30.
