What this measures

Public sector spending on defence in real terms, at 2024-25 prices using the GDP deflator.

What this doesn’t measure

Spending as a share of GDP, or spending in cash terms.

Important caveat

PESA classifies spending by function using the UN COFOG framework, so "health" is every public body's spending on health services, not the Department of Health's budget, and "defence" follows COFOG rather than the NATO definition. Figures are outturn for the whole public sector including local government and public corporations. Cash figures rise with inflation; the real-terms table restates them at 2024-25 prices with the GDP deflator. Classification changes are footnoted in the table: student loans from 2011-12, Network Rail from 2011-12 and the treatment of EU transactions after 2020. Total managed expenditure includes accounting adjustments that are not allocated to any function.
