The Barnett formula is a mechanism used by the UK government to automatically adjust the block grants (funding) given to the devolved administrations of Scotland, Wales, and Northern Ireland.
Here's a breakdown of how it works:
-
Starting Point: The formula uses the previous year's budget allocation as its base.
-
Comparable Spending in England: It then considers any changes in spending per person in England on comparable public services.
-
Population-Based Adjustment: The devolved nations' budgets are then adjusted based on these changes in English spending, multiplied by their respective population sizes. The formula effectively aims to maintain broadly similar levels of public spending per person across the UK.
-
Formulaic Calculation: The formula can be represented as:
Change in devolved funding = (Change in spending per person in England) x (Devolved nation's population)
Key Considerations and Implications:
- Comparability: A key issue is determining which spending in England is truly "comparable" to services provided by the devolved administrations. Disputes often arise over this.
- Needs Assessment: The Barnett formula doesn't directly take into account differing needs across different parts of the UK. Critics argue that it doesn't adequately address variations in factors like health needs or infrastructure requirements.
- Automatic Adjustment: The formula's automatic nature provides predictability but can also lead to perceived inequities, as it may not always reflect the specific priorities of the devolved administrations.
- Block Grant: The money received is in the form of a block grant which means each devolved administration has autonomy on how to spend it.
In Summary:
The Barnett formula is a population-based approach to allocating funds from the UK government to Scotland, Wales, and Northern Ireland, based on changes in comparable spending in England. It aims to maintain relative spending levels across the UK but has been subject to debate and criticism due to issues surrounding comparability and needs assessment.
