Official purpose - Scottish Government says to "estimate a set of public sector finance statistics for Scotland through detailed analysis of official UK and Scottish Government finance data."
It shows where Scotland is today INSIDE the UK. Not where it could be.
What it is NOT for:
1. It is NOT Holyrood's budget. Holyrood budget is about £60bn. GERS is £117.6bn because it includes pensions, welfare, defence, debt interest controlled by Westminster. 2. It is NOT a guide to an independent Scotland. GERS 2024-25 itself says it reflects being in UK and "not an independent Scotland with its own policy." 3. It is NOT a measure of affordability. No country's affordability is judged on a regional snapshot inside another country.
Why it matters now:
Under Barnett, Scotland's budget is decided by spending in England. If England spends more, Scotland gets a share. If UK pays more debt interest, Scotland is allocated a population share. GERS shows the result of that system.
In plain English:
Today is useful to understand where we are under devolution. It is useless to tell you where we would be under independence or full devo-max, because both would change the numbers completely.
