Brexit

Seeing as nobody has given a response to this I'll offer an idea or 2.

People work abroad for either better pay than at home or the experience. Some come to study and end up staying. The UK has had a good economy compared to some of the poorer EU countries, although the £ dropping to €1.15 from around €1.40-€1.45 where it should be wont be a big incentive now. The £ to Romanian Leu rate has actually improved, same as the € to Leu, so for Romanians working over here havent been affected by currency fluctuations. 20 years ago our pubs were awash with Ozzies and Kiwis behind the bar, not so much these days. 

Romanians are very good with foreign languages, I think in general everyone learns a foreign language at school. I met a Romanian couple in Germany and the women worked in logistics for Lufthansa and spoke several languages. The bloke spoke German, but not so much English. I said I was going to Romania on my bike later in the year and she mentioned if they didn't understand my Romanian (hadnt learnt any at that stage), didnt speak English, they were very likely to understand French or German. When I went to Romania, there were only 2 places off the tourist trail I stayed at where they only spoke Romanian (at 1 place a guest spoke fluent French so helped out with the finer details, think it was on-suite bathroom or room size). The other place they understood my Romanian, what nice people! 

So, where do Romanians go abroad to work? UK (800,000-900,000?), Germany (800,000), Italy (1.1m).  Italian and Romanian languages are very similar. An English bloke running a B&B in Romania said he could understand 80% of what Italians said.  More Romanians go to Italy than anywhere else and I reckon its down to language.

Brits are appalling at foreign languages on the whole. There are over 1m Brits in Australia, which has a good economy (currently better than ours no I'd say), decent weather although its too hot for my liking, and most importantly, they speak English. 

So its no surprise that Brits dont work in Europe, as we are shit at languages.  An exception is The Netherlands, it seems you can still make a career over there and not speaking the lingo *looking at Beefus here*.  I bet the 1.2m living in the EU arent all fluent in the local lingo.

There is old data from 2010, and the UK has the 7th highest number of people who were born outside their resident country as a % of the population. You can click on individual countries for more up to date data. UK data could change post Brexit.

So just using the 1.2m v 6m numbers to determine where is the best place to work is a none starter, I think its more complicated than that, with language an important issue.
