Disclaimer: I've only lived in North Wales and seen a little bit of North West Wales and Mid Wales but I've never been to the South, I'd say that the North is the whitest part of Wales (even though I see more Black people around here, nowadays) and the South has more Black people judging from what I've seen on TV.
Wales is very rural, surrounded by many beautiful fields, forests and mountainous areas, even some of the cities in North Wales (the place where I was born and still live in) get taken over by nature or are very close to the forests and the sea. I really enjoy living in Wales (despite Wales being predominantly white) and would say that I'm somewhat proud to be born in such a nice-looking place.
The challenges of living there includes the prices of houses and the rent to live in decent flats (apartments), the lack of many job opportunities in Wales' small towns (you're better off moving to Welsh cities if you don't want to be employed to work in retail or construction), there are many towns that are known for their drug problems, the amount of road works in the neighborhoods and motorways (highways) is ridiculous, the transport services (e.g. trains, buses etc.) are quite expensive and are prone to constantly getting shut down by their employees due to strikes and the councils that run many towns in our counties are pretty incompetent when it comes to their spendings for making the lives of people that live there easier and mainly seek to appease tourists and general foreigners.
I don't know a lot about Wales' Black History apart from the story of a Black woman called Betty Campbell (born 1934-2017) who was responsible for putting Black culture and Black History in Cardiff's educational curriculum (she even has her own statue in Cardiff) and a Black man called John Ystumllyn who was the first recorded Black person to live in Wales during the 17th century.
