|18. Statistical processing||Top|
|18.1. Source data|
Detailed monthly data on dairy activities are obtained by downloading the evidention of the Ministry of Agriculture, Forestry and Water Management (administrative source). Evidention is provided on the basis of monthly reports of dairies submitted through the web form (Monthly input of raw milk and products obtained at dairies). SORS is responsible for data entry, data processing and publishing.
Data on the production and use of milk and milk products on the holdings are obtained through the implementation of the regular Survey on agricultural production - livestock production. Data for 2018 are estimated on the basis of the Farm Structure Survey first results and results of the regural survey from previous years.
Due to the epidemiological situation in the Republic of Serbia caused by the corona virus COVID-19, Survey on agriculture production - animal production in 2021 was conducted by telephone - centarlized (CATI method) for family and entrepreneurial holdings, and by mail for legal entities, on a reduced sample size 0.9% of agricultural holdings, which has the effect of increasing the value of Coefficijent of Variation for the main variables.
For the purposes of calculating the annual data on milk and milk products, data on import and export of milk, cream and other milk products in bulk or in larger packages (2 l or more) by dairies in the reference year are also in use (data from external trade statistics).
Additional sources of data are the surveys of the SORS (internal trade statistics) regarding the purchase of agricultural products from individual producers (Monthly report on purchase of agricultural products from family farms) and realization of own production of legal entities in agriculture (Monthly survey on the realization of the agriculture production of legal entities), as well as data from industry statistics in the monthly and annual periodicity used for validation the obtained results.
|18.2. Frequency of data collection|
Dairy reports are collected in a monthly periodicity.
Survey on agricultural production - livestock production is carried out in the annual periodicity.
Data on purchase of agricultural products from individual producers and realization of own production of legal entities in agriculture (data of internal trade statistics), industry and export-import data are available in the monthly and annual periodicity.
|18.3. Data collection|
The dairies are obliged to sent monthly reports to the Ministry of Agriculture, Forestry and Water Management by the 20th of the month for the previous month, via the web questionnaire. The application was created in .net technology in the Microsoft SQL Server 2008 R2 database. Annual data on the quantities of used whole and skimed milk for the production of mik products and the quantities of proteins (tables B and H) are calculated by the output method (based on the content of milk fat and protein in the final milk products of dairies).
Triennial data on the structure of dairies and repurchase centers are provided by special processing of annual data on milk and milk products produced in dairies and annual data of internal trade statistics.
Data on the production and use of milk and milk products in farms are obtained through the implementation of the Agricultural Production Survey - livestock production in the period 2-16 December each year, by method of interview, through printed questionnaires on the field, by post and centralized by telephone. Complete data entry for farms in the sample ends on January 15th. Data processing for making and publishing of the first results is done by February 15th, followed by further data analysis and calculation of livestock production. The deadline for publishing the final results of annual statistics on livestock breeding (milk production, to the level of the region) for national needs is 1 April. After that, quantity of milk used for the production of certain milk products in the farms is calculated according to the coefficients given in the table, and preparation and transmission of data to Eurostat are done (tables C and I).
Table 10 Milk norms for certain milk products
For recalculating milk volume into milk weight measure, the following equation was applied: 1 ℓ milk = 1.03 kg milk.
Data on the purchase of agricultural products from individual producers and realization of own production of legal entities in agriculture (internal trade statistics) are collected by monthly reports of organizations that purchase agricultural products from family farms for the purpose of further sale or processing and monthly reports from agricultural and other organizations that sell / deliver agricultural products of their own production, by the 5th of the month for the previous month. After that data are entered and processed. The final data are available by the 30th of the month for the previous month, and the annual data by 10 March of the current year for the previous year.
Industry statistics provide data from the administrative records and documentation of reporting units. The statistics are collected through monthly and annual reports.
In order to provide data on the export and import of goods, the SORS takes over the Uniform Administrative Document ready for automatic data processing from the Republic Customs Administration by the 15th of the month for the previous month, and carries out further statistical control and processing. Monthly external trade data are available by the 30th of the month for the previous month, and the final annual data by July 15th for the previous year.
|18.4. Data validation|
Automatic and manual validation of data completeness is performed.
Validation of data is based on the results from the previous year and industry statistics.
|18.5. Data compilation|
Controlled data entry and processing is done in the IST program (developed in the SORS). During data processing, non-response of reporting units and non-response to certain key issues are solved by imputation of data from the report of the same reporting unit from the previous year or reports of other reporting units in the current year, if relevant and possible.
