Statistical presentation
Data description

The data are developed in compliance with the general requirements of Handbook of EU Agricultural Price Statistics, Version 2.0 March 2008.

Thus achieving harmonization in the field of price statistics and indices in agriculture with the EU practice with regard of definitions, techniques of price registration, type of calculated indices, survey periodicity and classifications used. Three data sets are calculated:

  • Prices of goods and services currently consumed in agriculture (quarterly and annual);
  • Price Indices of goods and services currently consumed in agriculture (quarterly and annual);
  • Price Indices of goods and services contributing to agricultural investments (quarterly and annual).

The purpose of the indices is to provide information about trends in purchase prices of products and services currently consumed in agriculture for comparisons between different products within a country or between Member States of the European Union, to compare trends in producer prices and the price of goods and services currently consumed in agriculture and for compilation of data on economic accounts for agriculture (as deflator for items of intermediate consumption in agriculture).

 

Classification system

Specific classifications of products and services currently consumed in agriculture are used. Classifications include representative products defined by their qualitative and quantitative characteristics of the following groups:

· Fertilizers;

· animal feeding stuffs;

· plant protection products;

· veterinary products;

· planting stocks and seeds.

Classifications of Consumer Price Indices, Import Price indices and Construction Production Indices are used for the goods and services contributing to agricultural investments.

Sector coverage

The Price index (input) is based on purchases of products and services currently consumed in agriculture and goods and services contributing to agricultural investments made by farm.

Statistical concepts and definitions
  • Price of Goods and Services currently consumed in agriculture

The goods and services currently consumed in agriculture are valued at purchase price, i.e. the price actually paid for the products Information is collected within five surveys on prices of:

  • Fertilizers;
  • animal feeding stuffs;
  • plant protection products;
  • veterinary products;
  • planting stocks and seeds.

For data collection on the prices of products and services currently consumed in agriculture specific nomenclatures are used which are updated if it is necessary once, usually when the base year is changed each five years. For the new nomenclatures representative products (most frequently purchased by agricultural holdings) are chosen, defined by their qualitative and quantitative characteristics.

The price information of the defined products is collected quarterly. According to the methodology the price of the largest purchase in quantity for each month of the reference period is taken into account. On the base of the collected prices not weighted average price of the product and simple and aggregate indices for the period are calculated.

  • Price Indices of Goods and Services currently consumed in agriculture (quarterly and annual)

The indices are calculated by the Laspeyre’s formula. It can be calculated for a period of several years without being necessary to alter the basket of representative products or the weights. Furthermore the parameters used for the calculation of the indices are well known at the time the base is established. Changes only need to be made when the evolution of the products used and of their relative importance have made the basic structure inappropriate.

  • Price Indices of goods and services contributing to agricultural investments (quarterly and annual).

For the calculation of the price indices of goods and services contributing to agricultural investments the following data sets are used: Consumer Price Indices, Import Price indices and Construction Production Indices.

  • Weighting scheme for the calculation of the indices.

For the calculation of Price indices (Annex 2 of the Handbook) a weighting scheme should be available. Weights are calculated within the frame of the economic accounts for agriculture and they reflect the costs incurred by the farm to purchase products and services for current consumption and investment purpose. The weights remain the same for the four quarters (one/forth of the annual weight) for each product group.

  • Annual Price Indices: 60 days after the end of the reference year data are sent to Eurostat and published on the website of NSI
  • Annual Estimates of Price Indices: 45 days before the end of the reference data are sent to Eurostat Data are not published on the website of NSI yet.
Punctuality

Not delays in the deadlines for submission of data to Eurostat and dissemination in the Calendar for presentation of the results of statistical surveys carried out by the NSI were admitted.

Coherence and comparability
Comparability - geographical

Data are geographically comparable for the entire period for which they are available.

Comparability - over time

Data are comparable over time for the entire period for which they are available.

Coherence - cross domain

There is data consistency between the Price Indices of Goods and Services currently consumed in agriculture and data on Consumer Price Index and Producer Prices Indices on the domestic market in industry (for fertilizers and animal feeding stuffs). There is consistency between the data on the economic accounts for agriculture in the development of weighting schemes for calculating price indices of goods and services currently consumed in agriculture.

Coherence - internal

Internal data consistency is ensured by monitoring the variation in the average price in comparison with the previous period. For this purpose specially developed software is used. If significant deviations are detected (+, -25% compared to the previous period) additional checks are made and sometimes extreme values are eliminated.

Cost and burden

The budget of the surveys is published in the National Statistical Programme on the NSI website. As basic criteria for response burden at this stage the time required for filling-in the questionnaire is used. Each form includes such section that respondents must complete. The time needed for filling-in the form includes also the time for data preparation. Based on this information, the burden on respondents can be defined as relatively high.

In 2011, by order of the President of NSI a special thematic working group was established. It consists of representatives of several RSO and its aim is to review and suggest measures for improvement of statistical tools in the field of statistics, agriculture and forestry. One of the main objectives of this review was to reduce the burden on respondents. As a result of suggestions made by the TWG has taken the following actions:

· further use of modern means for statistical data collection (introduction of on-line and off-line questionnaires);

· reducing the number of parameters in the statistical questionnaires;

· use of information from other sources.
