11.1. Quality assurance | |||
Prior to the statistical compilation arithmetic and logical control routines check the responses for error and lack of internal consistency. |
|||
11.2. Quality management - assessment | |||
The index of wholesale and retail sales is a high-quality statistic. Full coverage of many large chain-stores, as well as a random sample from the remaining population of reporting units allows for good estimates to be calculated. Since the index of wholesale and retail sales is calculated based on a random sample, some potential errors are inherent to the method. First, there is always a possibility of non-response. To monitor this, we calculate the non-response rate, and weighted non-response rate. Second, random sampling can lead to sampling errors. To understand the impact of this we calculate the coefficient of variance for the turnover estimates. All of the mentioned indicators are kept within reasonable limits. |
|

15.2. Comparability - over time | |||
The retail part of the index (G47) has been published since 1936. A new version of Norwegian industry classification (SIC2007) was implemented from January 2009. The G47 index, as well as three-digit sector levels, has been recalculated back to 2000 according to SIC2007. In January 2003, Statistics Norway altered the calculation method for the price index of retail sales. The new method is based on the price development of product groups from the consumer price index, as well as on sector-wise product allocation. The product allocation comes from a survey with that particular focus. The price index of retail sales is calculated using the same methods used to calculate the deflator of the retail sales component in the index of household consumption of goods. Volume figures have been calculated back to August 1999 using the current deflator. The volume indices at NACE four-digit sector level are calculated by deflating value indices using the aid of the price index for retail sales. From January 2002, volume indices at NACE two and three-digit sector level are calculated as a weighted sum of the volume indices at NACE four-digit sector level with value shares in the reference year as weight. In the past, volume indices at the NACE two and three-digit sector level were calculated using immediate deflation of value indices. The statistics was expanded in 2021 to also cover G45 and G46. Historical data back to 2015 has been estimated by disaggregating VAT turnover data. |
|||
15.3. Coherence - cross domain | |||
Coherence with other statistics: The index of household consumption of goods is published at the same time as the index of wholesale and retail sales. The former is more extensive than the latter, which can lead to different developments in the two indices. Price indices of retail sales are applied when calculating the volume indices of the retail sales. Changes in turnover are later compared with bimonthly retail sales statistics, which are based on the VAT register. Confrontation with other data sets: As part of the compilation routine the comparison of results with other data sources is carried out, mainly the bimonthly wholesale and retail trade statistics. |
|||
15.4. Coherence - internal | |||
The statistic is internaly coherent. |
|
|||
It is estimated that the random sample part of the statistics, which includes roughly 3000 units, represents a burden of 6000 hours per year for the respondents. |
|
||||||||||||||||||||||||
17.1. Data revision - policy | ||||||||||||||||||||||||
Published figures are final and no preliminary figures are released. Revised /corrected figures are only published in case of errors. Revised numbers are published simultaneously with a scheduled release of new monthly indices. The revisions are annonced simultaneously with the release. The same revision policy is applied nationally and in the transmission to Eurostat. |
||||||||||||||||||||||||
17.2. Data revision - practice | ||||||||||||||||||||||||
Revised numbers are published simultaneously with a scheduled release of new monthly indices. The revisions are annonced simultaneously with the release. Estimations of MR, MAR and RMAR are based on data from January 2020 to December 2022. For Calendar- and unadjusted indices year-on-year growth rates have been used in the calculations. For Seasonally adjusted indices period-on-period growth have been used. All MR, MAR and RMAR estimations are for the total of G47.

18.1. Source data | |||
Type of source: Combination of statistical surveys and administrative sources. Frame on which the source is based: Central Register of Establishments and Enterprises. Sample or census: Sample survey. The sample is adjusted regularly to ensure a reasonable geographical coverage. Adjustment of the sample ensures that updated information from the annual survey of the retail trade activity and from the bimonthly VAT registrations are incorporated. According to the VAT register, the adjustments focus on diverging trends of the turnover of the sample and the turnover measured by a survey of the VAT register. In 1997 the sample was adjusted to take into account the variation of strata variances. Once a year, in January, a part of the sample is substituted with new units from the VAT register. The local KAUs are retained in the sample for a maximum of four years, except for units deemed to be vital to the statistics, which can be included in the sample for as long as needed. Criteria for stratification: The sample is stratified according to the size of the local KAUs, in other words according to the number of employees. The largest units are usually included in the sample. Other units are selected from their respective strata by random sampling. Threshold values and percentages: A sample of about 18,200 units is selected from the population (local KAUs) in the VAT register. This includes a sub-sample of 15,200 chain-stores with direct reporting from their respective head-offices. Another sub-sample of 3,000 units is selected from other existing local KAUs, in other words independent shops and the remaining chain stores not yet included in the sample above. Including the sub-sample of chain-stores overall coverage for G47 exceeds 80% of the population. This represents Roughly a quarter of all units in the G47 part of the population. In terms of Sample variance accounted for by the sample of non-chain stores is estimated to about 1 percent for G47. Frequency of updating the sample: Once a year, in January, a part of the sample is substituted with new units from the VAT register. The local KAUs are retained in the sample for a maximum of four years, except for units deemed to be vital to the statistics, which can be included in the sample for as long as needed. |
|||
18.2. Frequency of data collection | |||
Monthly. |
|||
18.3. Data collection | |||
Questionnaires used in the survey: The questionnaire covers the value of retail sale. Data collection media: Questionnaires are submitted by post, on the internet or by other electronic means. If necessary, the respondents are supported by telephone contact. |
|||
18.4. Data validation | |||
The reported turnover is compared to relevant VAT data to validate the authenticity of the data. If the unit has been bart of the sample for several periods we will also compare the reported turnover to historically reported figures. If necessary, units are re-contacted to verify their reported figures. |
|||
18.5. Data compilation | |||
Estimates for non-response: When the final results are published non-respondents normally amount to some 4% of the sample. Estimates for grossing-up to population levels: A ratio estimator is applied to each stratum to expand sample results to represent the total population. Type of index: Index of turnover, gross data. Method of weighting and chaining: Since the index of turnover is a simple value index, no weights are used. For the indeces of deflated turnover, the weights used are the value shares from the VAT register in the base year 2015. The volume indices at NACE four-digit sector level are calculated by deflating value indices using the aid of the price index for retail sales. At NACE two and three-digit sector level the volume indices are calculated as a weighted sum of the volume indices at NACE four-digit sector level with the weights from the VAT register. |
|||
18.6. Adjustment | |||
The index of deflated turnover is adjusted for seasonal variations applying the X12ARIMA method with direct seasonal adjustment, non-fixed seasonal effects, a multiplicative model and pre-correction for working days and Easter effects. When it comes to the pre-correction for Easter effects, Statistics Norway has developed a method for distinctive Norwegian conditions that are not covered in the X12ARIMA package. For more information see the sub-section "About seasonal adjustment", under the section "About the statistics" in the following link: http://www.ssb.no/en/varehandel-og-tjenesteyting/statistikker/doi. |
