My observations is that there is two types of Muslims when it comes to migration patterns.
There is the clannish side, so if one family moves to an area, then one of their cousins and relatives want to move there as well. Our people have a level of autonomy in that we like to have a degree of boundary from our relatives. We are not keen to necessarily live close to each other.
The clan Muslims want to live close to each other as much as living on the same street or a couple of doors away from each other.
Our people do not have this level of co-dependancy that clan Muslims have. Our close-nitted Ness is not the same as their close nitted Ness.
Then you have the other type of Muslim, they are the more religious penguin and hijabi types. They seem to be more religious, maybe higher up the social ladder and they live in more far flung areas where you would find other communities. They seem to avoid the clan muslims.
I suspect that there are groups of muslims that want to keep away from other muslims.
You must note that since there are a lot of cab drivers of this community, they keep a note of where our people are moving to.
They manage to afford these houses by obtaining mortgages via non conventional routes. They have been using brokers for decades and a lot of times their mortgage providers are not institutions you have ever heard of.
Our people are typically straightforward on these things, if you want to find an alternative way of doing things or some loop holes, these people are experts.
I suspect the reason why you have seen more of them moving jnto your area is that around covid time, you had the stamp duty holiday in purchasing properties. The 3 years you have mentioned seem to co-incide during that time..
My personal opinion is that schooling is a big factor for our people moving but they are caught up with their parent's belligerent non budging out of an area. There are areas that have gone past their sell by date for our people.
