How many are seriously from this country going to live abroad compared to the numbers that have come to this country
Somewhere between 1 million and 1.5 million British citizens live permanently in the other EU countries. Ordinary people (and their families) getting on with life doing ordinary jobs in factories, offices, schools, hospitals and so on, just as they would be doing in the UK.
Freedom of Movement is not just about permanent residence though. It also includes mutual recognition of qualifications and the ability to undertake work on a temporary basis and to freely travel for business reasons.
Thousands of British citizens work or study in the EU on a temporary basis, so they are not counted in the 'permanent residency' figures.
45,000 British consultants work with EU clients. There are thousands of engineers who work for British companies and who design, build, repair and maintain British machinery and facilities, travelling to the EU for periods often lasting many months. There are sales personnel who are out in Europe drumming up business. There are thousands of commercial truck drivers and coach drivers whose licenses cease to be valid on March 29th in the event of a no-deal Brexit. Ditto thousands of airline pilots, engineers, flight crew etc.
The whole UK package holiday industry is based on sending 50,000 British holiday reps to Europe every year on temporary contracts (which interestingly undercut local wage rates and put local employers and businesses at a disadvantage). Supporting the holiday industry are also thousands of hospitality workers, bar staff, instructors etc.
There are employees working for European and international companies whose future job prospects have been removed by Brexit. Anyone working in a company whose job requires regular European travel, or relocation to HQ in say Sweden or Germany, is now disadvantaged compared with their European colleagues.
Finally, there are thousands of British citizens who are 'living' in the UK but who actually spend half of the year living abroad, mostly in Spain, Portugal and France. By only staying for a maximum of 90 days at a time, they circumvent the EU country's registration and tax laws.
