3.1. Data description | |||
Turnover and volume of sales index in retail tradeshow the performance of the goods market, this index is prepared as volume and turnover index, for the publication format this index is shown up in aggregate level only, as: retail trade, retail trade excluding retail sale of motor fuel, food, non-food, and retail sale of motor fuel, which derive from the processing of the ten (10) categories of an economic activity classes as follow. Indicators are expressed as indices and percent change (%). These categories result from the aggregation of the relevant economic activity classes (NACE Rev. 2 codes: 47.11-47.78). The ten categories of aggregated economic activity classes of the revised Retail Trade Turnover and Volume Indices are the following:
|
|||
3.2. Classification system | |||
NACE Rev.2 statistical classification of economic activities is applied, in conformity with Regulation (EC) 1893/2006 of the Council and the European Parliament and DCM 320, date 28.05.2014. For more information, follow the link. |

The Retail Trade Turnover Index (2015=100), according to the new NACE Rev.2 classification covers the economic activity divisions identified by codes 4711 to 4778 inclusive. |
|||
3.4. Statistical concepts and definitions | |||
The purpose of the Retail Trade Turnover Index is to show the performance of the goods market. The index does not cover other activities, such as provision of services. Turnover comprises the total amounts invoiced by the enterprise during the reference period, which correspond to the resale of goods without any further transformation. The data collected each month refer to sales affected, excluding VAT but including other duties and taxes on the goods. The sales volume represents the turnover value, at constant prices, and is a quantum index. It can be calculated as the turnover at current prices, deflated by applying the sales deflator. |

|
|||
13.1. Accuracy - overall | |||
Overall, the data is checked with previous years to identify any significant changes in the data. The sampled population of STS 2022 includes approximately 12,000 enterprises that are surveyed each quarter, from these around 3,500 enterprises are in retail trade activities. Sampling design is stratified simple random sampling. Criteria used for stratification is the number of employees according to the NACE Rev. 2 3-digit level.Calculating the estimates of statistical data and analysis evaluating outliers are done regularly. The overall accuracy rate is high, considering the high response rate. To calculate the estimates, Horvitz-Thompson estimator is used, that is unbiased. The accuracy of the estimates is reached by eliminating sampling errors and non-sampling errors, such as coverage, non-response, response mistakes and processing errors. Coverage errors reasons are: misclassification of units and changes in state of reporting units. In case of non-response, units are contacted by telephone and email. The sampling error in percent (CV) is calculated for main indicators of survey that are published every quarter. |
|||
13.2. Sampling error | |||
All indicator values are weighted to represent the population. Relative standard deviation in average for the variable Turnover is 2.08%. |
|||
13.3. Non-sampling error | |||
Unit non-response takes in consideration enterprises that are unable or unwilling to give the answers or when interviewers are unable to find enterprise addresses, or when other barriers exist to complete the interview. The unit non-response rate in average for Retail Trade 2022 is 2.31%. Item non-response rate in average for the main variable are: for the Number of employed is 0.8% while for Turnover is 0.8%. |
|
||||||||
14.1. Timeliness | ||||||||
Results of Turnover Index Volume of Retail Trade are published on INSTAT website 75 days after the end of the reference period (T+75 days). The reference period of these results is December 31st, 2022.
|
||||||||
14.2. Punctuality | ||||||||
The data of Turnover Index Volume of Retail Trade are disseminated according to the publication calendar. The publication of Turnover Index Volume of Retail Trade has been punctuality in time to 100% of publications carried out over the years.
|
|
|||
15.1. Comparability - geographical | |||
The retail trade turnover index and Volume index are produced in national level only, so rational comparisons are not available. But these indices are comparison in national level. |
|||
15.2. Comparability - over time | |||
The data series has been compiled since the year 1999. The first set of indicators was based on NACE Rev 1. For the last revision of the Retail Trade Turnover and Volume Indices (2010=100) from NACE Rev. 1. 1 to NACE REV. 2, it was deemed necessary to calculate parallel series for those indices including and not including fuel. This was due to the inclusion of fuel in retail trade in order to maintain comparability with the previous series of the Retail Trade Turnover and Volume indices (2005=100) and the indexes that have been calculated with NACE Rev.1.1. The process of passing from the old to the new base consists of two steps: re-weighting, i.e. the weights used for the calculation of the indexes are updated from the base year 2005 to the base year 2010; and re-referencing, i.e., the periods of reference are updated from 2005=100 to 2010=100. In 2019, in STS the weights structure is updated and the basic index period has changed from 2010 to 2015. The data series are equivalent to each other; the rhythms of the increase are the same, and a series is convertible to the other. Short-term Statistics data by quarters are compliant to NACE Rev. 2 Economic Activity Classification which dates back to 2006 and refers to the statistical database by providing a time comparability of 17 years (CC2 = Jlast-Jfirst + 1 = 17). The data are constantly checked to ensure their comparability over time. |
|||
15.3. Coherence - cross domain | |||
STS turnover in retail trade is for the greater part measured by using VAT data. For the enterprise that VAT data are not available data are collected through sample survey. There is no other statistical product that could be used for cross checking instead of the current indicators. |
|||
15.4. Coherence - internal | |||
The internal consistency of the data is checked before it is finalized. The links between variables are checked and coherence between different data series confirmed. Short-term Statistics specialists work together with relevant departments to ensure consistency and coherence of statistical indicators. |
|
|||
Short-Term Statistics is part of Directorate of Economic Statistics, while according to data collection is managed by the Directorate of Regional Statistics. The stuff included in the process of data collection, of validation and of updating of the data is consisted by full-time and parttime staff (enumerators). Total number of staff :
The part time staff is committed in data collection in a period of three weeks with a periodicity four times during a year.. Administrative data are available through Arrangements of Cooperation between INSTAT and the General Directorate of Tax Office and the National Registration Centre offers the opportunity of transition of data cost free. Statistical sources (of Business Register, of Structural Questionnaire of Enterprises etc.) are offered also free cost, as part of internal users. Processing, compilation, estimation, validation, analyzing, and valuation of data, is done by the stuff of STS and is not subject of any other added cost. |
|
|||
17.1. Data revision - policy | |||
Revision policy is done in accordance with general revision policy and errors treatment policy introduced by INSTAT in the links below: The same revision policy is applied to national releases and transmissions to Eurostat. |
|||
17.2. Data revision - practice | |||
Revisions are made each time when newer, completed or corrected figures for the different variables are available as well as for reasons such as: Implementation of the new NACE classification, methodological changes, new information or data improvements and error correction. But the revisions are generally rather limited in scale. Revision of the previous quarter is possible during each quarter and adjustments can be made at the end of each year for the four quarters. During 2022, “net-turnover (value) and sales volume in trade” has not been revised. No numeric values are available for MR and MAR indicators. |
|
|||
18.1. Source data | |||
Data are based on quarterly statistical surveys and administrative source. The basis of selection is the Register of active enterprises for the reference year. Classification of enterprises is done according to the Nomenclature of Economic Activities, NACE Rev. 2. Frame population is determined by two basic criteria: Size of enterprise (based on number of employed) and economic activity in scope, with cut-off. The method of selection used is Stratified Simple Random Sampling (SRS). Stratification is based on a combination of economic activity with size group of the enterprise. Indicators are presented for economic activities according to the areas specified in the STS regulation and also based on user needs. |
|||
18.2. Frequency of data collection | |||
Data collection is carried out quarterly, but the information is monthly |
|||
18.3. Data collection | |||
During 2022, data were provided in a combined way through administrative sources and data collected directly from enterprises with face to face interview. The surveyed data are collected by interviews with paper questionnaire on quarterly basis, 15 days after the end of the reference period. Duration of this survey is 15 working days. No changes in national questionnaires are planned. |
|||
18.4. Data validation | |||
Data received from survey and from VAT file are validated using logical validation rules. At national level, editing involves studying data from respondents with the aim of identifying (and eventually correcting) errors. Not all errors can be identified and the aim is to detect the errors that have a significant influence on the results. Rules to assist in identifying errors may flag possible errors that require further investigation to determine where there really is an error as opposed to an unusual result or they may identify definite errors. Editing involves checks for completeness, that values are within given ranges and that values for related variables are coherent. Data editing may take place during or after data entry. Responses can be compared to the response of previous quarters. Inconsistency or large deviations (outside of a pre-established range) indicate that a closer look is desirable. This may result in data editing. In the context of timeliness, the editing process may be designed to give top priority to those outliers that are most in need of editing for the sake of reliable aggregates. By solving the worst cases, large improvements can be achieved. |
|||
18.5. Data compilation | |||
First step is collecting information from the interviewers. The purpose is to bring this information to the statistic target level. This process follows:
The Retail Trade Volume Index is obtained from the Retail Trade Turnover Index deflated in accordance with the Consumer Price Index (CPI), as follows: Using CPI data, deflator-indices are compiled for the corresponding groups of the Turnover Index. More specifically, deflators are calculated for ten categories of economic activity classes of the index. To deflate the Turnover Index and convert it to a Volume Index, the individual Turnover Indices are divided by the appropriate deflators. |
|||
18.6. Adjustment | |||
Seasonal and calendar adjustment of monthly/quarterly time series of retail trade is done by using JDemetra+ 2.2.0 version software. The chosen model for the decomposition of time series is X-12 ARIMA, under specification X-13. X-12 ARIMA model is totally based in moving average. In all time series is applied the multiplicative decomposition and the direct approach. In calendar adjustment is applied the specification of trading day and a national calendar, considering both moving and fix national holidays. During the process of seasonal adjustment there are treated even the special cases occurred during time series span, identified by software as outlier. |
