On July 17, 2020, HM Treasury published its Public Expenditure Statistical Analyses (PESA) for 2020. 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 2020. The update includesspending data for 2019-20, anddata for 2020-21. 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 provideestimates for future Local Authority spending, ukpublicspending.co.uk provides "guesstimates" instead. This is done by extending the percentage increase in spending between 2018-19 and 2019-20 for each sub-function for theyear. It is assumed that local authority spending reductions willcarry through toyears.Country and Region spending has been updated up to 2018-19. These are obtained from Chapters 9 and 10 in the PESA document.
