You need to do your own research, not base your decision on opinions of strangers.
If your DC's safety is a concern then research crime stats in UK Vs where you live now. Find the facts, not the news, which is always biased.
We are planning to leave the UK when my son is 18-20 and able to stand on his own 2 feet. I worry about his safety but not overly as we are in a small city and he's quite sensible. we'd leave sooner but in Cyprus where we want to move to education opportunities are poor Vs UK. But it is a much safer country.
I hate the erosion of free speech here in the UK, I have to watch what I say to people because I'm afraid I'll get a knock on the door from the police.
I hate the government that is focused on taking my family's money to give to other people so they can live the life of Riley while barely lifting a finger. They have no plans for economic growth. The cost of living is forever rising and rising while wages on the private sector stagnate. There's going to be an implosion when today's 30-40 year olds retire and find their workplace pensions are not enough to live on.
Our NHS is rubbish and our healthcare is slipping well behind other developed nations, social care is out of reach except for the minority.
Our young adults are struggling desperately to find work and can't so remain dependent on their parents, which is fine of parents can afford to keep them but many can't. This will get worse for a number of years before it gets better due to AI, but you will find similar elsewhere.
And even if a different party is elected next time it will be a decade before we see any noticeable improvement.
On the other hand, banking is good, there is very little corruption, banking sector isn't corrupt, food is cheap, education is very good until 18. Culturally I fit, there's so much to do no matter what you're interested in you will find others who are your interests.
