The UK has a population of 66.5 million. Just for comparison, Sweden has twice the land mass of the UK and a higher standard of living, yet it's population is less than 10 million. You might want to bear that in mind.
The UK annual death rate (latest tabulated figures 2016) is 9.1 deaths per 1000 population:- (Download and examine the spreadsheet)
i.e. Every year the population naturally increases by 2.7 per 1000 population without immigration.
My apologies to anyone who took the incorrect figures (2.5 per 1000) I posted in another thread at face value. The actual figure is much, much higher.
The net immigration rate (Q3 2018) is 4.11 per 1000 population, or 1.52 times the natural population increase:- (Download and examine the spreadsheet. Correlate with UK population from other data sets)
Just for comparison, the number of Mediterranean migrants that reached europe in 2017 was 171,635. That's about 100,000 LESS than the net migration into the UK. If the Mediterranean migrants entering europe were a crisis, what do you call over one and a half times that number entering just the UK ?
Every year, the UK population is increasing by approximately 448,000. (271,000 net immigration + 774,823 births - 597,206 deaths)
Every extra human life introduces an increase to the support structure we have decided we need, i.e. gas, electricity, water, housing, policing, roads, hospital, food etc, etc and the problems it creates. A lower population would mean lower crime, pollution, house prices, hospitals needed, imported food / medicines / goods / home food production etc, etc.
It's already too late to maintain a reasonable population level in the UK like Sweden, we can only slow the exponential rate of increase by drastically cutting immigration. The solution is staring us in the face, but the politically correct, gullible numpties go apoplectic and scream "racist xenophobe" at the very mention of it, without offering alternative solutions to the (exponential) increase of problems we are now witnessing, in their mistaken belief that unfettered immigration can continue until the end of time itself - however, the maths don't lie.
Little wonder that the s*** is hitting the fan. Some people would have this situation continue. I'd wish the younger generations good luck, but let's face it, they're screwed.
Oh well, never mind. My little corner of the UK is OK and virtually insulated from the wider effects of population growth - and I can always move somewhere with a lower population density (in all meanings of the word) if I want to.
In relation to your well put post, I have a simple yet scientifically proven fact. If you pour a pint of boiling water into a glass vessel and then put a teaspoon of sugar in it will dissolve unnoticed. Put another one in it will dissolve again. Carry on for a few more and then, oh, its no longer dissolving and thats what is happening to britain. Proper brits are the boiling water, immigrants are the sugar. We can no longer accept the swarm of sugar.
