I've had a good look but I can't find any statistics that cover a long enough period to shed light on whether the number of child abuse deaths have changed under various governments.
Jup a trick that various government's in many different countries do, they just class it at something else and no problem no issue, except for the victims that is.
Works for wide range of topics too. It only becomes a problem when you have something grossly underfunded like the healthcare and a pandemic comes to visit.
It's complicated by the fact that some earlier stats don't record child abuse deaths separately - so the rise in fatal stabbings of/by under 16's for example would muddy the data.
Well Child death is the end result, very rarely it starts with killing a child it mostly starts with abuse, which should be addressed by social services, which failed both Arthur and Star, and somehow they always seem to find a way to blame somerthing else.
Similar as police always seem to need more resources/spying laws when a terrorist attacks something they should have seen because board arsenal of tools they already have.
Fatal stabbings are a whole other story, they have much more to do with the youth criminality system and druglords misusing that, glorification of gang culture and so on. ( Yes if music with rappers and such that brag about knifes, guns voilence and drugs and the money that it brings , is populair amongst some groups and they then go on to copy that there is a casual connection. )
It would seem plausible that reduced funding for social services would result in cases being missed but, from what I've read, in the cases of deaths of younger children/babies the parents were mostly not known to social services anyway.
Both recent examples of Arthur and Star had little to do with funding, but everything with misjudging the situation.
Perhaps better education would have learned the social workers to better look at the hidden messages or not let them be outplayed with an ''it's because we are lesbian'' story, but it's impossible to say more funding would have really helped.
It seems faster and better action when the regulatory body deemed the service ineffective would be a better starting point.
