	Research by the University of Cambridge published in 2018 said that the greatest reductions in local authority spending had occurred in impoverished post-industrial cities in the north of England and some poor Inner London boroughs. Over 30 such authorities in England had reduced spending by more than 30% between 2010 and 2017, with seven of them reducing spending by more than 40%. In contrast councils in wealthier areas had made smaller reductions. Councils in England experienced an average spending reduction of 24% compared to 12% in Scotland and 11.5% in Wales, the difference resulting from devolved government in those nations.
