Abstract: Now that the United Kingdom voted in favor of exiting from the European Union, a process commonly known as Brexit, there is a possibility that we will witness a tremendous migration wave between the EU and the UK once Brexit is implemented. This will ultimately affect every aspect of European society and will have repercussions on the global economy and geopolitics. In this paper, we analyze the migration effectiveness between the EU and the UK. The results indicate that, currently, there is an efficient redistribution of the population in favor of the UK, compared to most other EU countries. For instance, the number of UK citizens living in Belgium, Cyprus, Luxemburg and Spain is greater than the number of citizens of Belgium, Cyprus, Luxemburg and Spain living in the UK. Between France and the UK, there is an almost equal number of migrants living in each country. The UK must contend with the possible migration of a significant percent of the 2.9 million EU migrants currently residing in the UK. In addition, the UK has to update its policies to accommodate the 0.8 million UK citizens living in other EU countries.

英国脱欧：欧盟和英国的潜在移民潮和人口得失

摘要：既然英国投票赞成退出欧盟，这个过程通常被称为英国退欧，一旦英国退欧实施，我们有可能见证欧盟和英国之间的巨大移民潮。这最终将影响欧洲社会的方方面面，并对全球经济和地缘政治产生影响。在本文中，我们分析了欧盟和英国之间的移民有效性。结果表明，与大多数其他欧盟国家相比，目前有利于英国的有效人口重新分配。例如，居住在比利时、塞浦路斯、卢森堡和西班牙的英国公民人数多于居住在英国的比利时、塞浦路斯、卢森堡和西班牙公民人数。在法国和英国之间，生活在每个国家的移民人数几乎相等。英国必须应对目前居住在英国的 290 万欧盟移民中的很大一部分可能的移民问题。此外，英国必须更新其政策以容纳居住在其他欧盟国家的 80 万英国公民。
