Britain is poised to outpace Germany and have the largest population in Western Europe by the year 2100. It will topple its European neighbour from the top of the ranking and grow from 65 million to more than 80 million.

These are the projections contained in the newly-published report by the United Nations on the world population.

France will see its population jump by 10 million from 64 million to 74 million.

Germany and Spain, in contrast, will each see their populations fall by 10 million.

Germany’s will drop to 71 million from 81 million while Spain will see a fall from 46 million to 36 million. Italy will lose 12 million and dip from 59 million to 47 million people.

The report says that there will be one billion more people on the planet by 2030. The population will go from the current 7.6 billion to 8.6 billion. It will continue to grow and push through the 11 billion mark by 2100.

According to the study, the world population will continue to grow at an average of 83 million people a year, despite an expected fall in fertility. By 2024 India will surpass China and, with more than 1.5 billion inhabitants, become the most populous country in the world.

The 2017 Revision of World Population Prospects is the twenty-fifth round of official United Nations population estimates and projections that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat.
