By 2050, Britain will become the most populous country in Europe.

According to a report published by the UN in 2050 in the UK will live 72,4 million, which will lead the country in the first place in Europe. The main population growth will occur at the expense of immigrants, which averaged 174 thousand people a year, reports The Daily Telegraph.
The researchers note that by 2050 Britain will hold the third place in the world more attractive to immigrants. Most foreigners will take the U.S. - 1.1 million people a year, Canada, with its 214 thousand immigrants per year, will take second place.
Currently residing in the UK 61.1 million people in Europe by this indicator, it is inferior to Germany (82 million) and France (62 million). However, after 40 years, predicted UN experts, the German population will decrease to 71 million people, and will be living in France 68 million. The reason for reducing the number of people in Germany, researchers called the low birth rate and the overall aging of the population with a much smaller number of migrants (110 thousand people per year).
Britain will be leaders not only on the total number of inhabitants, but at an average density of population. Currently, the EU leaders on this indicator, the Netherlands, but in 2050, for every square kilometer of 393 people will live, but in Britain it will be 395 people. Malta, with its record 1274 inhabitants per square kilometer, the rating is not because the experts consider it to exceptional cases which do not reflect general trends.
UN experts predict that if current trends continue by 2050 the population of the planet will be 9.1 billion people today to 6.8 billion. The number of older people in the world will triple to nearly 2 billion people. The average life expectancy will increase from 68 to 76 years. Despite the overall increase in world population, the average birth rate would decline from 2.56 children per woman today to 2.02 in 2050.
  In connection with the publication of forecasts from the UN, many policies of Great Britain has expressed support for the tightening of immigration policies to prevent the increase in population until the "unacceptable". In their view, a sharp increase as the total number of inhabitants and an average population density, would adversely affect the living standards of the British.
