So I go back to my point, I use the data because it shows that unemployment is not caused by immigration, and why do I use it? Because none of my personal experience covers a large enough area, or enough detail for me to make an informed decision. Your own exprience, doesn't for you either.
My own experience is wide & varied.
I stated earlier the wide range of friends, acquaintances & former work colleagues.
I have close family in Scotland (Perth, Dundee, Fife), friends in Aberdeen, Stirling, Moray, Glasgow & Edinburgh.
Husband's family are South Wales, I have lived & have friends in Oxfordshire, various places in Scotland, Lincolnshire, Midlands, Buckinghamshire, Hampshire.
Friends all over England and also Northern Ireland.
Friends who are graduates, friends who are not, friends who are skilled trades, journalists, hospitality, unskilled, menial, office based.
Using my eyes, ears and general wherewithal I can understand the impact that has been felt across many areas of the UK.
