You might find it interesting to read about the history of British Mirpuris - the majority of British people of Pakistani descent are ultimately from this area, which is a rural conservative area where, e.g., kinship bonds are considered extremely important, cousin marriage is quite common, and your loyalty is to your "clan" rather than a higher nation-state. In the UK this sometimes (not always but disproportionately) translates to e.g. clan based voting or protecting your cousin from the law.
Why is this interesting? Because to @FrauPaige 's question, this knowledge should affect how we run immigration policy.
For example, one proposal I have heard for restricting immigration is that we need to have stricter limits on people coming here on work visas, but any British person should have the right to bring their spouse over ("the one they love") without income limits.
Pakistan is by far one of the top countries for spouse visas, and for the historic reasons mentioned above, in practice this is very often people bringing in relatives from Mirpur & surrounding rural regions, because kin is so important.
It should be obvious that this is the opposite of integration. The reason there are income limits at all is to try to restrict this effect somewhat. It's not because the government thinks it's a problem for a junior nurse to fall in love with an Aussie bartender or something.
So the question is: should the above context be taken into account when setting immigration policy? e.g., rejecting the policy proposal above? Or should we pretend we don't know this?
