While the article above says 1 in 5 children in Scotland are living in poverty, it also says
“Scotland has lower levels of child poverty than England or Wales. However, campaigners in Scotland say that whilst progress is being made there can be no room for complacency if Scotland’s statutory child poverty targets, which were agreed by all the Holyrood parties, are to be met.
The Child Poverty (Scotland) Act requires the Scottish Government to ensure fewer than 18% of children are living in poverty by 2023/24, on course to achieving less than 10% by 2030.”
So not far from achieving their target.
Although the rise in inflation, including the surge in energy prices, unleashed by the UK government will make it difficult, the extension of the Scottish Child Payment to children aged 6 to 15 by the end of 2022 will help.
In Wales 1 in 3 children are living in poverty.
