A surge in the number of the elderly will push the U.K.'s population significantly higher by 2030, according to a report by the Institute for Public Policy Research.
"The U.K. will be the fastest growing major country in Europe, overtaking France by 2030," IPPR said in its report, "Future proof: Britain in the 2020s." More specifically, the number of people aged 65 and over will increase by 33 percent between now and 2030 while those aged over 85 will nearly double in the next decade.
However, the U.K.'s working population will rise by only 2 percent in the same period. This is set to deteriorate public finances further, with a structural deficit expected to re-emerge by mid-2020s, IPPR added in the report.
In June, the U.K. voted to quit the European Union (EU) with immigration and the free movement of people cited as one of the main reasons for the anti-Europe feelings.
Surprisingly, even in a post-Brexit outlook – with constraints on migration, which should lead to a fall in net migration over the short-term – the number of migrants are nonetheless set to represent nearly half of the increase in the population in the 2020s.
"While immigration is expected to be lower and more controlled after Brexit, economic and social demand are likely to continue to drive relatively high levels of immigration to the UK," IPPR said in its report. The research group showed that the non-white population is seen increasing from 14 percent in 2011 to 21 percent by 2030.
