The Retail Sales Index (RSI) measures spending (value) and volume of retail sales in Great Britain. Figures are adjusted for seasonal variations unless otherwise stated and the reference year for both value and volume statistics is 2006 = 100. For an explanation of the terms used in this bulletin, please see the background notes section. Care should be taken when using the month on month growth rates due to their volatility, an assessment of the quality of the retail statistics is available in the background notes.

It shows the distribution of the reported growth of businesses in the RSI sample, ranked by size of business (based on number of employment). For example, this shows that the largest retailers, with 100 or more employment, reported an average increase in sales of 5.8 per cent between July 2010 and July 2011.

New ONS website
The launch of the new ONS website on 28 August 2011 will bring changes to the design and format of statistical bulletins. The bulletin main body will be in html and pdf format but detailed data tables will be available as Excel spreadsheets only. The new website will improve the way users can access our statistics but many existing bookmarks and links will no longer work and users will need to update them.

Understanding the data
Interpreting the data
The Retail Sales Index (RSI) is derived from a monthly survey of 5,000 businesses in Great Britain. The sample represents the whole retail sector and includes all large retailers and a representative panel of smaller businesses. Collectively all of these businesses cover approximately 95 per cent of the retail sector in terms of turnover.
The RSI covers sales only from businesses registered as retailers according to the Standard Industrial Classification (SIC), an internationally agreed convention for classifying industries. The retail sector is division 47 of the SIC 2007 and retailing is defined as the sale of goods to the general public for household consumption. Consequently the RSI includes all internet businesses whose primary function is retailing and also covers internet sales by other British retailers, such as online sales by supermarkets, department stores and catalogue companies. The RSI does not cover household spending on services bought from the retail sector as it is designed to only cover goods. Respondents are asked to separate out the non-goods elements of their sales, e.g. income from cafeterias. Consequently on-line sales of services by retailers, such as car insurance, would also be excluded.
The monthly survey collects two figures from each sampled business: the total turnover for retail sales for the standard trading period, and a separate figure for sales made over the internet. The total turnover will include internet sales. The separation of the internet sales figure allows an estimate relating to internet sales to be calculated separately.
Definitions and explanations
• The value or current price series records the growth since the base period (currently 2006) of the value of sales ‘through the till’ before any adjustment for the effects of price changes.
• The volume or constant price series are constructed by removing the effect of price changes from the value series. The Consumer Price Index (CPI) is the main source of the information required on price changes. In brief, a deflator for each type of store (5-digit SIC) is derived by weighting together the CPI’s for the appropriate commodities, the weights being based on the pattern of sales in the base year. These deflators are then applied to the value data to produce volume series.
The estimated prices of retail sales (sometimes called the implied price deflator) is derived by comparing the value and volume data non-seasonally adjusted. In general, this implied price deflator should be quite close to the retail component of the CPI.
Experimental statistics are those which are in the testing phase and are not yet fully developed. The main reason why the Internet retail sales are designated as experimental is that the methods and data sources are still being improved.
Retail sales index categories and their percentage weights in 2009 are available to download under "data with this release".
Use of the data
The value and volume measures of retail sales estimates are widely used in private and public sector institutions, particularly by the Bank of England and Her Majesty’s Treasury, to assist in informed decision and policy making.
Information on retail sales methodology is available on the ONS website
A video explaining retail sales is available on the ONS You Tube Channel
Composition of the data
Estimates in the Statistical Bulletin are based on financial data collected through the monthly Retail Sales Inquiry. The response rates for the current month reflect the response rates at the time of publication. Late returns for the previous month’s data are included in the results each month. Response rates for historical periods are updated to reflect the current level of response at the time of this publication.
|Overall response rates|
Seasonally adjusted estimates are derived by estimating and removing calendar effects (e.g. Easter moving between March and April) and seasonal effects (e.g. increased spending in December as a result of Christmas) from the non-seasonally adjusted (NSA) estimates. Seasonal adjustment is performed each month, and reviewed each year, using the standard, widely used software, X-12-ARIMA. Before adjusting for seasonality, prior adjustments are made for calendar effects (where statistically significant) such as: returns that do not comply with the standard trading period (see section methods, calendar effects), bank holidays, Easter and the day of the week Christmas occurs.
The calculation of the RSI has an adjustment to compensate for calendar effects which arise from the differences in the reporting periods. The reporting period for July 2011 was 3 July 2011 to 30 July 2011 compared with 4 July 2010 to 31 July 2010 the previous year. For example, the annual growth in sales volume between July 2010 and July 2011 requires 0.1 per cent adjustment to take account of the differences in reporting periods and other calendar effects.
The following table shows the difference between the calendar and seasonally adjusted estimates.
|Year on year percentage change|
Basic quality information
The standard reporting periods can change over time due to the movement of the calendar. Every five or six years the standard reporting periods are brought back into line by adding an extra week. For example, January is typically a four week standard period but January 1986, 1991, 1996, 2002 and 2008 were all five week standard periods. The non-seasonally adjusted estimates will still contain calendar effects. If the non-seasonally adjusted estimates are used for analysis this can lead to a distortion depending on the timing of the standard reporting period in relation to the calendar, previous reporting periods and how trading activity changes over time.
The non-seasonally adjusted series contain elements relating to the impact of the standard reporting period, moving seasonality and trading day activity. When making comparisons it is recommended that users focus on the seasonally adjusted estimates as these have the systematic calendar related component removed. Due to the volatility of the monthly data, it is recommended that growth rates are calculated using an average of the latest three months of the seasonally adjusted estimates.
When interpreting the data, consideration should be given to the relative weighted contributions of the sectors within the all retailing series. Based on SIC 2007 data, Total retail sales consists of: predominantly food stores 42.0 per cent, predominantly non-food stores 43.3 per cent, non-store retailing 4.5 per cent and automotive fuel 10.2 per cent.
A measure of the accuracy of the RSI has been produced by estimating the standard errors of index movements.

Revisions to data provide one indication of the reliability of key indicators. The table below shows summary information on the size and direction of the revisions which have been made to the volume data covering a five year period. Note that changes in definition and classification mean that the revision analysis is not conceptually the same over time. A statistical test has been applied which has shown that the average revision in month to month statistics are not statistically different from zero.
