Statistical bulletin: Retail Sales, March 2013 This product is designated as National Statistics

Released: 18 April 2013 Download PDF

Key Points

  • Users are reminded that the figures contained within this release are estimates produced from a monthly survey of 5,000 retailers in Great Britain. Unless otherwise stated, the estimates in this release are seasonally adjusted.
  • In March 2013, the quantity bought in the retail sector (or sales volumes) decreased by 0.5%. This follows strong year-on-year growth of 2.5% in February 2013 and a year-on-year decrease in January of 0.6%. Quarter 1 2013 does however show an increase of 0.4% compared with Quarter 4 2012.
  • The largest contribution to the year-on-year decrease came from the non-food sector, where compared with March 2012, the quantity of goods bought decreased by 2.6%.
  • March 2013 was the second coldest on record and this appears to have had a negative effect on sales in the non-food sector. Feedback from department stores, clothing stores and household goods stores suggested that sales were dampened by the weather as they prepared their stores for the spring season.
  • In March 2013, the overall proportion of non-seasonally adjusted online sales remained high at 10.4% reflecting feedback from large retailers, which suggested that during the continued winter weather consumers purchased from their online sites rather than in store.
  • The amount spent (or sales values) in the retail sector increased by 0.1% between March 2012 and March 2013. The largest contributions came from the food and non-store retailing sectors.
  • Looking at the monthly picture, (March 2013 compared with February 2013) the quantity bought decreased by 0.7%, whilst the amount spent remained unchanged at 0.0%.

Key Figures

This bulletin presents estimates of the amount spent and quantity bought in the retail sector for the period 24th February 2013 to 30th March 2013. The statistics are based on a monthly survey of 5,000 retailers, including all large retailers employing 100 people or more. The timeliness of these retail sales statistics, which are published just two weeks after the end of each month, makes them an important early economic indicator. The sector as a whole is used as an indicator of how the wider economy is fairing and the strength of consumer spending.

At a Glance

In March 2013, the quantity of goods bought in the retail sector (volume) decreased by 0.5% compared with March 2012. The amount spent (value) increased by 0.1% over the same period.  Since March 2012, non-seasonally adjusted data show that the prices of goods sold in the retail sector (as measured by the implied price deflator) increased by 0.6%. More information on how the implied price deflator is measured can be found in the background notes.

Long Term Picture

To enable a comparison of change, Figure 1 shows the quantity of goods bought in the retail sector (all retailing sales volumes) as indices referenced to 2009. Between 2003 and early 2008, the quantity bought grew steadily. Since the beginning of 2008, growth has slowed and become more volatile compared with early years.

Users are reminded that Retail Sales Indices are currently referenced to 2009, making the average index in 2009=100.

Contributions to Growth

The retail industry is divided into four retail sectors; predominantly food stores, predominantly non-food stores, non-store retailing and stores selling automotive fuel. In March 2013, for every pound spent in the retail sector 41 pence was spent in food stores, 42 pence in non-food stores, 5 pence in non-store retailing and 12 pence was spent on fuel. Using these as weights along with the year-on-year growth rates we can calculate how each sector contributed to the total year-on-year growth in the quantity bought.

Figures 2 and 3, show the contribution that each sector had to the quantity bought (volume) and amount spent (value) in retail between March 2012 to March 2013.

Sales within the non-store retailing sector provided the main source of upwards pressure to the quantity bought (sales volumes) in the retail sector in March 2013. The main source of downwards pressure came from non-food stores.

In March 2013, growth in both non-store retailing and food stores contributed to the increase in the amount spent (sales values). The main source of downwards pressure came from non-food stores; further detail is provided in figure 4.

In non-food stores, household goods stores, clothing stores and non-specialised (or department) stores showed falls in March 2013 compared with March 2012. Feedback from retailers suggested that whilst they prepared for spring, the continued winter weather hampered sales.

 

Amount spent in retail

In the March 2013 five week reporting period, the amount spent in the retail sector was £32.9 billion (non-seasonally adjusted). This compares with £25.4 billion in the February 2013 four week reporting period and £32.6 billion in the March 2012 five week reporting period.

This equates to an average weekly spend of £6.6 billion in March 2013, £6.3 billion in February 2013 and £6.5 billion in March 2012.

 

 

 

 

 

Internet Sales

Key points

  • The average weekly spend online (internet sales values non-seasonally adjusted) in March 2013 was £601.4 million. This was an increase of 20.5% compared with March 2012.

  • The amount spent online accounted for 10.4% of all retail spending excluding automotive fuel.

  • As expected, more was spent online in the non-store retailing sector than any other sector. Spending online now accounts for 68.4% of total spending in this sector. In the food sector 3.4% of spending was online. This sector has the lowest proportion of online spend in relation to all spending.

Internet sales in detail

Internet sales measure how much was spent online through retailers across all store types in Great Britain. Figures are non-seasonally adjusted and the reference year is 2010=100. Table 2 shows the year-on-year growth rates for total internet sales, by sector and the contribution that each sector makes to total internet sales.

Distribution Analysis

Table 3 illustrates the mix of experiences among different sized retailers. It shows the distribution of reported change in sales values of businesses in the RSI sample, ranked by size of business (based on number of employees). This table shows for example, that the largest retailers, with 100 or more employees, reported an average increase in sales values of 1.5% between March 2012 and March 2013. In contrast smaller retailers employing 10 to 39 employees reported an average increase in sales of 23.2%.

    2. 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 the 900 largest retailers and a representative panel of smaller businesses. Collectively all of these businesses cover approximately 90 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, for example income from cafeterias. Consequently, online 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.

    3. Definitions and explanations

    • The value or current price series records the growth since the base period (currently 2009) 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 Prices 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 CPIs 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 implied deflator or the estimated price of goods is derived by dividing the non-seasonally adjusted value and volume data to leave a price relative. In general, this implied price deflator should be quite close to the retail component of the CPI. More information on the implied price deflator can be found in the Quick Guide to Retail Sales.


    4. Use of the data

    The value and volume measures of retail sales estimates are widely used in private and public sector organisations. For example, private sector institutions such as investment banks, the retail sector itself and retail groups use the data to inform decisions on the current economic performance of the retail sector, these organisations are most interested in a long term view of the retail sector that can be obtained from year-on-year growth rates. Public sector institutions use the data to assist in informed decision and policy making and tend to be most interested in a snapshot view of the retail sector, which is taken from the month-on-month growth rates.

  4. Methods

    Information on retail sales methodology is available in Retail Sales Methodology and Articles

    1. Composition of the data

    Estimates in this 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.

    2. Seasonal adjustment


    Seasonally adjusted estimates are derived by estimating and removing calendar effects (for example Easter moving between March and April) and seasonal effects (for example 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 on which Christmas occurs.

    The data collected from the retail sales survey is the amount of money taken through the tills of retailers; these are non-seasonally adjusted data. These data consists of three components:

    • trend which describes long-term or underlying movements within the data

    • seasonal which describes regular variation around the trend, that is peaks and troughs within the time series, the most obvious in this case being the peak in December and the fall in January

    • irregular or ‘noise’, for example deeper falls within the non-seasonally adjusted series due to harsh weather impacting on retail sales

    To ease interpretation of the underlying movements in the data, the seasonal adjustment process estimates and removes the seasonal component to leave a seasonally adjusted time series consisting of the trend and irregular components.

    In the non-seasonally adjusted retail sales index we see large rises in December each year and a fall in the following January, but these are not evident in the seasonally adjusted index. This peak in December is larger than the subsequent fall but the trend and irregular components in both months are likely to be similar, meaning that the movements in the unadjusted series are almost completely as a result of the seasonal pattern.

    3.  Calendar effects


    The calculation of the RSI has an adjustment to compensate for calendar effects that arise from the differences in the reporting periods. The reporting period for March 2013 was 24 February 2013 to 30 March 2013, compared with 26 February 2012 to 31 March 2012 the previous year. Table 5 shows the differences between the calendar and seasonally adjusted estimates.

  5. Quality

    1. 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 41.3 per cent, predominantly non-food stores 41.6 per cent, non-store retailing 5.3 per cent and automotive fuel 11.8 per cent

    2. Standard errors

    The standard error of an index movement is a measure of the spread of possible estimates of that movement likely to be obtained when taking a range of different samples of retail companies of the same size. This provides a means of assessing the accuracy of the estimate: the lower the standard error, the more confident one can be that the estimate is close to the true value for the retail population. An approximate 95 per cent confidence interval for the index movement is roughly twice the standard error. The paper ‘Measuring the accuracy of the Retail Sales Index’ (1.04 Mb Pdf) , written by Winton, J and Ralph, J (2011) reports on the calculation of standard errors for month-on-month and year-on-year growth rates in the RSI as well as providing an overview of standard errors and how they can be interpreted.

    • The standard error for year-on-year growth in all retail sales volumes is 0.7 per cent. This means that the year-on-year growth rate for all retail sales volumes falls within the range 0.3 ± 1.4 per cent with a probability of 95 per cent.

    • The standard error for month-on-month growth in all retail sales volumes is 0.4 per cent. This means that the month-on-month growth rate for all retail sales volumes falls within the confidence interval -0.1 ± 0.8 with a probability of 95 per cent.

    4. Revision triangles


    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.

    A spreadsheet giving these estimates and the calculations behind the averages in the table is available on the ONS website.
