Govanhill has always been an area for new immigrants, with Irish and Pakistanis in the 60s/70s, then gradually becoming more Pakistani as the Irish moved out. So it was always poor but reasonably respectable and the schools were good
From around late 90's/2000, there were also several guest houses and hostels which accommodated a large number of heroin addicts. At that time, I believe Glasgow City Council was one of the few councils which housed many drug addicts in the same place, the other councils in Scotland would dump their addicts and GCC were happy to take them. I had a house one of the nearby areas and would often have addicts showing up at my door looking for money. The area changed from being friendly to very threatening
An entire Roma village was moved to Govanhill some years back. There was an immediate effect with increased crime etc.
There is a view that GCC (Labour council) are more than happy to dump problems in Govanhill because it is Nicola Sturgeon's constituency. Childcare, housing, social work etc are run by the council. Not necessarily trying to defend NS as such, but it is a convenient truth for Labour councillors
But certainly, having lived in Govanhill several times in my life over decades, the truth is I wouldn't even walk down the streets now. Victoria Road used to have lovely shops but is now betting shops, charity shops and payday loans places. Queens Park feels very unsafe. There was a horrific murder of a local woman, Moira Jones by an Eastern European immigrant. He dragged her to Queens Park, raped and brutally murdered her. We lived nearby at the time and it was the final nail so we moved away.
The local schools now have a large majority of children whose English is poor, which is obviously going to have an effect on the quality of the education. One of my clients sits on the Children's panel and tells me that the parents of Roma girls simply don't see the value in educating girls and actively prevent them from going, so that they can do domestic duties.
