The media and the authorities are in denial over where the real issues are in regards this.
I think that most UK Sikhs are very aware where the problem lies at an intuitive level.
I think that most of population of the UK are very aware, it is the same pattern that repeats itself over and over again yet the powers that be and the media do not want to connect the dots even though it is clearly obvious to everyone else.
I am not sure how many more candlelight vigils or speeches of how we are "united" and "we will not be divided" can be stomached.
There has been large push to reduce population.
For men overall, there has been a large decline in testosterone levels and sperm count.
However. you will probably know that the consequence of reduced fertility is the demographic imbalance where the over 65s have increased their proportion in society. This means that there will be less young working people to support an ageing population.
This results in older people having to work longer, pressures on the health system etc. I know in the UK, retirement age is 67 currently but I know there are reports which suggest this should go up to 70.
According to this article the fertility of Sikhs in India is 3.1.
The replacement rate is 2.1.
I have no idea what the fertility rate in the west is for Sikhs are.
But surely it is above 2. Most Sikhs have at least 2 children.
My personal opinion is that Sikh families that tend to be larger are ones that are trying for a child of a particular sex.
I have seen plenty of families where there are 3/4 girls and 1 boy. The boy is usually the youngest.
I have also personally known 1 family that has 5 boys and that is because they keep trying for a girl and they keep having boys.
One of the common expressions you will usually hear after a second child is born is "family is complete".
