2. Statistical presentation Top
2.1. Data description

Data collection comprises pesticide sales in Malta.  The Malta Competition and Consumer Affairs Authority (MCCAA) is the competent authority in Malta concerning the authorisation and control in relation to dealing, advertising and use of any plant protection product, biocidal product or any other active substances intended for use in any plant protection and/or biocidal product.  These terms are defined as follows:

Plant protection product: products consisting of or containing active substances, safeners or synergists, and intended for one of the following uses: protecting plants or plant products against all harmful organisms or preventing the action of such organisms, unless the main purpose of these products is considered to be for reasons of hygiene rather than for the protection of plants or plant products; influencing the life processes of plants, such as substances influencing their growth, other than as a nutrient; preserving plant products, in so far as such substances or products are not subject to special Community provisions on preservatives; destroying undesired plants or parts of plants, except algae unless the products are applied on soil or water to protect plants;  checking or preventing undesired growth of plants, except algae.

Active substances: substances or micro-organisms, including viruses, having general or specific action against harmful organisms or on plants, parts of plants or plant products.

The list of active substances that could be sold in Malta is provided by the MCCAA.  Data from the officially recognised importers in Malta is collected according to Regulation (EC) No 1185/2009 of the European Parliament and of the Council, of 25 November 2009, concerning statistics on pesticides which establishes a common framework for the systematic production of Community statistics on the placing on the market and use of those pesticides.

2.2. Classification system

3. Statistical processing Top

Data collected from the importers was checked with imports declaration and where there some inconsistencies, importers were again contacted and data was verified.

3.1. Source data

The NSO obtains the data of the Maltese industries via the list of officially recognized importers in Malta provided by MCCAA.  Data is collected through an online survey (via email) where the total amount of kilograms and/or litres sold of every product is collected.  Then, by using the composition in weight, the total amount of active substance sold for each product is calculated.

3.2. Frequency of data collection

Annual.

3.3. Data collection

The importers are contacted by means of an email in which they are explained about the importance of providing the sales data according to the Regulation (EC) 1185/2009 of the European Parliament.

3.4. Data validation

Data collected from importers is checked with the data of previous years and where there are inconsistencies, the importers are contacted again for further verification of figures.

3.5. Data compilation

The total amount of kilograms and/or litres sold of every product is collected.  Then by using the composition in weight, the total amount of active substance sold for each product is compiled.

3.6. Adjustment

Not applicable.


4. Quality management Top
4.1. Quality assurance

The overall quality of the sales of pesticides is stable from one year to another.

4.2. Quality management - assessment

The data collection is exhaustive and detailed processes are in place for the data validation and data analysis.  For this reason, the overall quality of AEI statistics is good.


5. Relevance Top
5.1. Relevance - User Needs

The main user of the data is Eurostat.

5.2. Relevance - User Satisfaction

A user satisfication survey was carried out in 2014.  Results are specific to the NSO unit but not to the particular domain.

5.3. Completeness

100%

5.3.1. Data completeness - rate

100% complete, all data required by Regulation (EC) 1185/2009 is collected.


6. Accuracy and reliability Top
6.1. Accuracy - overall

Collected data for the reference year is inputted manually by a statistician and checked for consistency by another person.  Data is also compared with past data. In case large discrepancies emerge in the amount of pesticides sold, the importer(s) are contacted again to verify the figures. These measures ensure that the overall accuracy of AEI statistics is high.

6.2. Sampling error

Not applicable since a census of all authorised importers is considered and all the required data is collected.

6.2.1. Sampling error - indicators

Not applicable since a census of all authorised importers is considered and all the required data is collected.

6.3. Non-sampling error

There are validation rules in place so that such an error is kept to a minimal level.  However, possible sources for such an error include data entry errors.

From the data collected from the importers, the active substance of each of the product is derived from the list obtained from MCCAA. The active substances are then classified according to the harmonized classification of substances presented by Eurostat.

6.3.1. Coverage error

There are no coverage problems.  The list of authorised importers is obtained from MCCAA

6.3.1.1. Over-coverage - rate

Not applicable.

6.3.1.2. Common units - proportion

Not applicable, only one source is utilised (census of importers).

6.3.2. Measurement error

There are validation rules in place so that such an error is kept to a minimal level.  The questionnaire is an excel sheet containing the name of the pesticides imported by the respective importer and the importer has to fill in the amount of kilograms sold.

However, measurement errors may result at the point when data is collected from the importers as for certain products they could provide the amount sold in litres for a certain product instead of Kgs. The NSO addresses such processing errors by checking the data as soon as it is provided by the importers.

6.3.3. Non response error

Not applicable since all the authorised importers answer the questionnaire.

6.3.3.1. Unit non-response - rate

0% since all the authorised importers answers the questionnaire.  When we request the data from the importers we inform them that the supply of information is compulsory under the Malta Statistics Authority ACT XXIV 2000.

10. Cost and Burden Top

All the data collection, data inputting and analysis are done by one statistician. No costs are involved in the data collection since this is done via email. Besides, it does not have a significant burden on the respondents since the importers are obliged to keep a record of their sales transactions for a period of five consecutive years and thus they need to complete the questionnaire using readily available information.


11. Confidentiality Top
11.1. Confidentiality - policy

At National level: Confidentiality is one of the major principles guiding the activities of the NSO.

 

Article 40 of the MSA Act stipulates the restrictions on the use of information and in Article 41, the prohibition of disclosure of information. Furthermore, Section IX of the Act (Offences and Penalties) lays down the measures to be taken in case of unlawful exercise of any officer of statistics regarding confidentiality of data. No cases of breaches in the law have been recorded to date.

 

Since its inception, the NSO has always operated within a culture of strict confidentiality to which it is also bound by the provisions of the Data Protection Act. This Act, which came fully into effect on July 15, 2003, seeks to protect individuals against the violation of their privacy by the processing of personal data.

 

Further information on access to microdata is available on the NSO's website through: https://nso.gov.mt/en/Services/Microdata/Pages/Access-to-Microdata.aspx

 

During 2009, the NSO has set up a Statistical Disclosure Committee to ensure that statistical confidentiality is observed, especially when requests for microdata are received by the NSO.

Upon employment, NSO employees are informed of the rules and duties pertaining to confidential information and its treatment. According to the MSA Act, before commencing work, every employee is required to take an oath of secrecy whose text is included in the Act.

11.2. Confidentiality - data treatment

If a plant protection product that contains a particular active substance is sold by only one or two importers such data is flagged as confidential and will not be disseminated.
