... c'mon, mate ... use your eyes!! You know as well as I do, that Mainland ... as a tiny island off the coast of Europe, is grossly overpopulated in proportion to its size - particularly in areas such as the North of England, the Midlands, and certain East London boroughs - hence some stringent measure of control needs to be exercised.
... it does NOT include Filipinos. Filipinos - unlike many other immigrants - are highly valued here. Deservedly so ... by virtue of their reputation for being a friendly, industrious people - whose efforts have long since contributed SIGNIFICANTLY to our nation's economy - and, as such, can easily integrate into British society.
... up to a point. Nevertheless, human nature being what it is, people will nearly always gravitate towards LARGER cities - ANYWHERE - simply because that is where most job opportunities [and amenities] are to be found. Therefore, it's hardly surprising that the areas I mentioned above will, in turn, account for the greatest population density ... rural parts of Scotland, Wales and Northern Ireland to a lesser extent, obviously.
And as for the "right people" ... yes! But the trouble IS, this country is all too often a magnet for attracting the wrong sort ... those who somehow manage to enter illegally ... while the authorities relentlessly persist in making it difficult for decent, law-abiding folk who want nothing more than to settle with their British husbands and/or wives.
Totally !
