10.1. Dissemination format - News release | |||
The main dissemination channel for official statistics is the NSO website (http://www.nso.gov.mt). A quarterly news release is published on the industrial indicators and another news release covers retail and services indicators. |
|||
10.2. Dissemination format - Publications | |||
The short-term statistics only publishes its figures in an annual compendium named Malta in Figures or Trends in Malta. These can be accessed from the NSO website:www.nso.gov.mt |
|||
10.3. Dissemination format - online database | |||
The NSO website offers an online statistical database (StatDB) that provides a more in-depth analysis for the more expert statistical user or researcher. The StatDB requires registration as only registered users can extract data from the database. Registration is free-of-charge. |
|||
10.4. Dissemination format - microdata access | |||
In general, index results made available to Eurostat ensure a sufficient degree of representativeness of data. More detailed data than that published locally and internationally are available on request but are subject to the confidentiality clauses. In such cases, data are provided in index form. Micro data are not provided to users. |
|||

Data are transmitted to Eurostat. |
|||
10.6. Documentation on methodology | |||
The main document used for the production of this index is the following: European Business Statistics Regulation, 2021 https://ec.europa.eu/eurostat/web/products-manuals-and-guidelines/-/ks-gq-21-001 |
|||
10.7. Quality management - documentation | |||
Not available. |
|
|||
11.1. Quality assurance | |||
The NSO quality assurance principles are developed according to the ESS Handbook for Quality Reports (2014). |
|||
11.2. Quality management - assessment | |||
Aspects of quality are divided into several steps. These are specifying needs, designing and building data instruments and collecting, processing, analysing, disseminating, archiving and evaluating data. The main guiding principles in quality management are found in the: European Statistics Code of Practice and in the European Business Statistics Manual, 2021. Overall, the quality of the labour indicators for all domains is reliable. |
|
|||
12.1. Relevance - User Needs | |||
The main users of these indices are the following: - Eurostat - Central Bank of Malta - Ministry of Finance, Malta - Other international organisations |
|||
12.2. Relevance - User Satisfaction | |||
Not available |
|||
12.3. Completeness | |||
Data are compliant with relevant European and local regulations and requirements are fully fulfilled. |
|
|||
13.1. Accuracy - overall | |||
The overall accuracy of the variables is considered to be of good quality. Sampling error is considered to be small, non-sampling error is small and the first estimates are not biased. |
|||
13.2. Sampling error | |||
Sampling error is considered to be small or not applicable because for many of the NACE categories, the sample designs are based on cut-off thresholds. |
|||
13.3. Non-sampling error | |||
Non-sampling errors relate to problems such as under or over coverage, non-response, data-processing and estimation. Non-sampling errors in the labour indicators are mainly due to non-response error. Hence, the Short-term Statistics unit make use of administrative data and good estimation techniques where needed. The hours worked variable may suffer a bit more from this problem than the other labour indicators. This is due to the relatively more difficult computational nature of the variable from the part of the units in the sample. Administrative Registers help us to fill in a lot of non-response. Weighted response rate is over 75% using employment as the weighting variable. |
|
|||
14.1. Timeliness | |||
Industry and services labour variables are released 60 days after the end of the reference period while construction and retail labour variables are released 75 days after the end of the reference period. Questionnaires are sent a week before the end of the reference period. |
|||
14.2. Punctuality | |||
The NSO is committed to adhere to the timelines established by the European Business Statistics Regulations 2019/2152 and 2020/1197 and also issues news releases according to its pre-published calendar. All deadlines were respected during the course of the year. |
|
|||
15.1. Comparability - geographical | |||
To ensure geographical comparability across member states the indices are compiled according to the European Business Statistics Regulations 2019/2152 and 2020/1197 and the STS Methodological Guidelines. |
|||
15.2. Comparability - over time | |||
The data series has been compiled since the year 2000. The first set of indicators was based on NACE Rev 1. Following 2009, the indicator was published according to the new NACE Rev 2 classification. Furthermore, for every year ending in 0 or 5, new fixed aggregation weights are introduced. There is no break in series in the data. |
|||
15.3. Coherence - cross domain | |||
Employment data are sometimes compared to administrative data, however no other checks are made. |
|||
15.4. Coherence - internal | |||
Aggregates may not always be consistent with sub-aggregates due to the nature of the index calculation. |
|
|||
Data burden is considered high but no data are available. |
|
|||
17.1. Data revision - policy | |||
Revisions are carried according to the European Business Statistics Regulation. Internal procedures are also established. The same revision policy is applied to both data released nationally and that sent to Eurostat. Revision analysis is carried out before every news release published locally or sent to Eurostat and clear explanations are also sought. Detailed explanations at micro data level are also analysed but only used internally for quality information purposes. Generally, this index will have routine minor revisions due to actual data replacing estimates due to non-response. Major revisions may also be done but this will be on an exceptional basis. A revision calendar does not exist. |
|||
17.2. Data revision - practice | |||
Data marked as provisional are revised when actual data are received and estimates are replaced. |
|
|||
18.1. Source data | |||
Data on the industrial labour variables are based on a sample survey of around 200 units. Data on the construction labour variables are based on a sample survey of around 135 units. Data on the retail trade labour variables are based on a sample survey of around 700 units. Data on the services labour variables are based on a sample survey of around 800 units.
The samples are refreshed every 5 years and turnover and employment are the main indicators used to stratify the samples into 3 size strata. In certain NACE divisions, a cut-off of 80% was used for the Base 2015 data. |
|||
18.2. Frequency of data collection | |||
Industry labour variables - monthly. Construction, retail trade and services - quarterly. |
|||
18.3. Data collection | |||
Data are collected by means of a monthly statistical questionnaire. Questionnaires are sent by post and their collection is done via post, fax, e-mail or online systems. |
|||
18.4. Data validation | |||
Validations of format and file structure checks and intra-dataset checks are checked with the use of in-house excel sheets and access databases. Revisions analysis is also carried out for every data transmission sent to Eurostat using in-house access queries. When data revisions are significantly large, a short explanation is also given to Eurostat. |
|||
18.5. Data compilation | |||
Non-response is treated by micro-estimation to ensure a full response for all surveyed units. A Laspeyres type index is used for compilation and the weights are updated every 5 years from the Structural Business Statistics survey. The current file conversion is GESMES/TS and the plan is to use the SDMX-ML tool in the future. |
|||
18.6. Adjustment | |||
Necessary working day and seasonal adjustments are made to the variables of hours worked and gross wages and salaries. No adjustments are made to the employment variable.
The software used for adjustments is JDemetra+ 2.2.0. The calendar used is country-specific and replacement of outliers is not done. The direct method of adjustment is used for all the variables. Models are revised once every year and the whole time series is revised with every additional data. To check the quality of the indicators, the Charts and S-I Ratio in the Main Results tab are always checked. Calendar effects are checked by analysing t tests, p values and outlier effect. Seasonality is checked mainly by analysing the stability and seasonality tests (Friedman test, Kruskall-Wallis test, evolutive seasonality test, combined seasonality test and residual seasonality test) of the series. There are no seasonal breaks and filter length is chosen automatically. Adjusted data is then compared with the previous transmission / news release to check for any large discrepancies. |
