The Economist reports on a UNDP report that sets out likely global population (by country) in 2050.
You can choose to see the data by graph, map or in data files.

The headline figures show that while Europe’s population will fall (from 2015 to 2050) by    about 4%, that of Africa will rise by over 100%, and that India will overtake China as the most populous country.

The Economist says that the total number of people will grow from 7.3 billion   to 9.7 billion in 2050, 100m more than was estimated in the UN’s last report  two years ago.  More than half of this growth comes from Africa, where the population is set to double to 2.5 billion.

Nigeria’s population will reach 413m, overtaking America as the world’s third most-populous country. Congo and Ethiopia will swell to more than 195m and 188m repectively, more than twice their current numbers.

NB, changes in fertility make long-term projections hard, but by 2100 the planet’s population will likely be rising past 11.2 billion.  It will also be much older. The median age of 30 will rise to 36 in 2050 and 42 in 2100 – the median age of Europeans today.  A quarter of Europe’s people are already aged 60 or more; by 2050 deaths will outnumber births by 32m.

The UN warns that only migration will prevent the region’s population from shrinking further.
