Additionally, this demographic (I won't name the religion - I'm sure you know the one I'm describing) has a male unemployment rate of 50% and female unemployment rate of 75% in the UK.
You don't die as a country through low birthrates - this could only happen in a bygone era that required massive labourforce, agriculture, factory work etc. No - the modern economy does not require "throwing bodies at the problem." We are entering the age of automation, a having more humans in a country is not as important as having the smartest humans to build the automation.
In fact having more humans in the country just creates an aging population timebomb. This problem is confounded by immigration. Not resolved by immigration. Immigrants age just like the rest of us.
Every other statement after that is also utter nonsense pseudo opinion.

Since we're pointing at random articles: http://www.independent.co.uk/news/uk/home-news/british-musli...
"The recent national Labour Force survey showed the unemployment rate among Muslim women was 18 per cent, compared with 9 per cent for Hindu women and 4 per cent for white Christian women."
No doubt unemployment rate is higher for Muslim women, and it is a problem. But citing figures that out of your pocket isn't gonna help.
The latest report, from 2015, makes for interesting reading. It shows that:
a. White people have a higher rate of employment than for ethnic minorities generally (74.7% vs. 59.3%)
b. Men have a higher rate of employment than women, and women are more likely to be in part-time work and less likely to be in senior management positions.
c. Religious minorities are more likely to be unemployed, and in particular Muslim men experience the highest levels of unemployment.
There's no analysis though of why any of this is the case though. All the things you highlight aren't necessarily issues that can't be overcome. But you have selectively cherry-picked what you want to see, and I can't see that you can provide any sources that back up your assertions about why Muslims face high unemployment.
