This report is the twenty-second in the series of official published estimates of expenditure and revenue balances of the public sector in Scotland.
GERS is classified as National Statistics and produced in accordance with the principles of the Code of Practice for Official Statistics. More information about National Statistics, including the latest assessment report on GERS (number 274), is available on the UK Statistics Authority website.
The GERS content and methodology is continually reviewed in conjunction with users. The latest consultation about this edition of GERS was carried out between November 2015 and January 2016. A summary of responses was published in February 2016.
Feedback from users of the publication is welcome. A correspondence address is available in the back leaf of the publication. Comments can be emailed to: email@example.com
What Questions Does GERS Address?
GERS addresses three questions about Scotland's public sector accounts for a given year:
1. What revenues were raised in Scotland?
2. How much did the country pay for the public services that were consumed?
3. To what extent did the revenues raised cover the costs of these public services?
Public sector revenue is estimated where a financial burden is imposed on residents and enterprises in Scotland.
Under current UK budgetary accounting procedures, separate figures for each country and region of the UK are not available for most revenues. As a result, Scottish public sector revenue is estimated by considering each revenue stream separately. Where Scottish data are unavailable, GERS estimates revenue using a set of apportionment methodologies, refined over a number of years following consultation with and feedback from users.
The methodology note on the GERS website provides a detailed discussion of the methodologies and datasets used.
Public sector expenditure is estimated on the basis of spending incurred for the benefit of residents of Scotland. That is, a particular public sector expenditure is apportioned to a region if the benefit of the expenditure is thought to accrue to residents of that region.
This is a different measure from total public expenditure in Scotland. For most expenditure, spending for or in Scotland will be similar. For example, the vast majority of health expenditure by NHS Scotland occurs in Scotland and is for patients resident in Scotland. Therefore, the in and for approaches should yield virtually identical assessments of expenditure. However, for expenditure where the final impact is more widespread, such as defence, an assessment of 'who benefits' depends upon the nature of the benefit being assessed. Where there are differences between the for and in approaches, GERS estimates Scottish expenditure using a set of apportionment methodologies, refined over a number of years following consultation with and feedback from users.
The for approach considers the location of the recipients of services or transfers that government expenditure finances, irrespective of where the expenditure takes place. For example, with respect to defence expenditure, as the service provided is a national 'public good', the for methodology operates on the premise that the entire UK population benefits from the provision of a national defence service. Accordingly, under the for methodology, national defence expenditure is apportioned across the UK on a population basis.
The methodology note on the GERS website provides a detailed discussion of the methodologies and datasets used to undertake this task.
The Data Sources
The source of the revenue data in GERS is ONS's Public Sector Finances, which provides disaggregated figures relating to UK public sector revenue.
The primary data source used to estimate Scottish public sector expenditure in GERS is the Country and Regional Analysis (CRA) data published by HM Treasury.
GERS also makes use of the estimates of Scottish Gross Domestic Product (GDP) in current market prices published in the Quarterly National Accounts Scotland (QNAS). 
Additional Information on the GERS Website
The GERS website contains a number of additional analyses of Scotland's public sector finances. In addition to containing copies of the GERS report from 1990-91 onwards, the website also contains the tables underpinning this edition of GERS in Excel form and statistics providing a consistent time series of Scotland's public sector finances from 1998-99 to 2014-15. A detailed database showing each individual spending line, and how they are adjusted from those published in the CRA, is also available for the last five years.
The Scottish Government, other devolved administrations, and HMRC are committed to working together to reconcile, and where possible, align methodologies for estimating receipts for the countries and regions of the UK. Further details on this work can be seen in Box 1.1 in Chapter 1.
