On July 20, 2015, HM Treasury published its Public Expenditure Statistical Analyses (PESA) for 2015. ukpublicspending.co.uk uses the PESA tables of public spending at the "sub-function" level as its major data source for UK public spending. ukpublicspending.co.uk has now updated its spending tables using data from PESA 2015. The update includes outturn spending data for 2014-15, and plans data for 2015-16. ukpublicspending.co.uk uses PESA's Table 6.4 for Central Government expenditure, Table 7.4 for Local Authority expenditure, and Table 8.3 for Public Corporation capital expenditure. Since HM Treasury does not provide plans estimates for Local Authority spending, ukpublicspending.co.uk provides "guesstimates" instead. This is done by extending the percentage increase in spending between 2013-14 and 2014-15 for each sub-function for the plans year. It is assumed that local authority spending reductions will not carry through to plans years. Country and Region spending has been updated up to 2013-14. These are obtained from Chapters 9 and 10 in the PESA document.
