3.1. Data description

The Economic Accounts for Agriculture (EAA) provide an overview of the agricultural activities in a systematic and comparable way to serve as basis for analyses, forecasts and political measures. The methodology is laid down in Annex I of the Regulation (EC) 138/2004 of the European Parliament and of the Council and Regulation (EU) 2022/590 of the European Parliament and of the Council of 6 April 2022 amending Regulation (EC) No 138/2004 as regards regional economic accounts for agriculture. The EAA methodological manual provides further details and clarifications (website).

3.2. Classification system

The EAA are a satellite account of the European System of Accounts (ESA), therefore EAA constitute an integral part of the ESA. As such, they are compiled based on NACE Rev. 2.1, the statistical classification of economic activities in the European Community. The list of activities, which defines the agricultural industry corresponds, in principle, to Division 01 of that classification: Crop and animal production, hunting and related service activities. However, some differences exist that are detailed in Annex I of Regulation (EC) 138/2004 of the European Parliament and of the Council.

3.3. Coverage - sector

The sector covers all units involved in agricultural production, even if some of those units have other more important economic activities even if the purpose of these activities is not commercial. However, kitchen gardens (producing for own-consumption only) are not included. The list of agricultural activities covered by EAA corresponds to the seven groups of Division 01 of NACE Rev. 2.1 activities (01.1 to 01.7), with the following differences: inclusion of the production of wine and olive oil (exclusively using grapes and olives grown by the same holding), exclusion of certain activities which, in NACE Rev. 2.1, are considered as agricultural services (e.g. the operation of irrigation systems - only agricultural contract work is taken into account here).

3.4. Statistical concepts and definitions

The EAA are a satellite account of the ESA providing complementary information and concepts adapted to the particular nature of the agricultural industry.
The EAA are shown as a sequence of inter-related accounts. As the EAA are based on the industry concept, the sequence of accounts is limited to the first accounts of the current accounts:

the production account (its balancing item: value added)
the generation-of-income account (its balancing item: operating surplus).

Nevertheless EAA contains other accounts (of the ESA) at least partly:

the entrepreneurial income account (one of the current accounts) and
the capital account (one of the accumulation accounts).

The EAA provide a wide range of indicators on the economic activities of the agricultural sector: these include output, intermediate consumption, gross and net value added, gross fixed capital formation (GFCF), both at current prices and at reference year prices, as well as compensation of employees, other taxes and subsidies on production, net operating surplus or net mixed income, property income and net entrepreneurial income at current prices. (see for more details points 1.40-1.48 in Annex I of Regulation (EC) 138/2004.)

Three income indicators are defined in the EAA:

Index of the real income of factors in agriculture per annual work unit (indicator A).
Index of real net agricultural entrepreneurial income per unpaid annual work unit (indicator B).
Net entrepreneurial income of agriculture (indicator C).

See for more details chapter 5 in Annex I of Regulation (EC) 138/2004.

3.4.1. Components of the Production account : Output

Agricultural output is the total of the agricultural products and the goods and services produced in inseparable non-agricultural secondary activities during the accounting period. It is recorded as a resource in the production account and it is valued and recorded at the time it is generated, i.e. when produced and not when paid by the purchaser. In the compilation of the EAA, output is progressively broken down in quantity terms (see point 2.037 of Regulation (EC) 138/2004).Output is valued at the basic price. The basic price is the price receivable by the producers from the purchaser for a unit of a good or service produced, minus any tax (i.e. taxes on products) payable on that unit plus any subsidy (i.e. subsidies on products) receivable on that unit. The basic price excludes any transport charges invoiced separately by the producer. It also excludes holding gains and losses on financial and non-financial assets. The valuation of output at the basic price makes it necessary to distinguish between taxes (other than VAT) on products and subsidies on products, on the one hand, and other taxes and subsidies on production, on the other.The components of output in the production account are detailed in ANNEX II of the Regulation (EC) 138/2004. The other categories are wider, defined by the countries according to their special characteristics. The table below covers the list of products included under ‘other’ categories.

3.4.2. Components of the Production account : Intermediate consumption

Intermediate consumption represents the value of all goods and services used as inputs in the production process, excluding fixed assets, the consumption of which is recorded as fixed capital consumption.

The inputs used for intermediate consumption should be valued at the purchaser prices for similar goods and services applicable at the time of their insertion in the production process. The purchaser price includes taxes less subsidies on products (but excludes deductible taxes like VAT on the products). It also includes any transport charges paid separately by the purchaser to take delivery at the required time and place.

The components of intermediate consumption in the production account are detailed in ANNEX II of the Regulation (EC) 138/2004. The other categories are wider, defined by the countries according to their special characteristics. The table below only covers the list of products included under ‘other’ categories.

3.4.3. Components of the Generation of income account

In the generation of income account, the distributive transactions relate to other taxes on production, other subsidies on production and the compensation of employees.The components of the generation of income account are detailed in ANNEX II of the Regulation (EC) 138/2004.

3.4.4. Components of the Entrepreneurial income account

The entrepreneurial income account records certain types of property income (mainly land rents, interest and property income attributed to insurance policy holders).The components of the entrepreneurial income account are detailed in ANNEX II of the Regulation (EC) 138/2004.

3.4.5. Elements of the Capital account

In addition to gross fixed capital formation (GFCF), the capital account records distributive transactions corresponding to aid for investment and other capital transfers.

The elements of the capital account are detailed in ANNEX II of the Regulation (EC) 138/2004.

3.5. Statistical unit

The statistical unit is the local kind of activity unit.

In order to provide more detailed information and to analyse flows generated by the production process and the use of goods and services, it is necessary to select units which emphasise relationships of a technical-economic kind. This means that, institutional units are broken-down into smaller and more homogeneous units with regard to the kind of production (local kind-of-activity units/local KAUs) (ESA 2010, 2.147).The local KAU is defined as the part of a KAU which corresponds to a local unit. The institutional unit's information system is capable of indicating or calculating for each local KAU at least the value of output, intermediate consumption, compensation of employees, the operating surplus and employment and gross fixed capital formation (ESA 2010, 2.148).

The agricultural holding is the local KAU most appropriate to the agricultural industry. However, the variety of agricultural activities that can be performed on agricultural holdings makes them a special type of local KAU. The strict application of the ESA rule to units and their group should in fact result in a division of the agricultural holding into several separate local KAUs in cases where several activities of the NACE Rev. 2 four-digit class are performed on the same holding and the information required according to the explanations above is available. The adoption of the agricultural holding as the local KAU of the agricultural industry in the national accounts (NA) and EAA is based on a statistical approach.

The speciality and the aim of EAA is to cover all agricultural activity carried out by an agricultural holding or any other local KAU not having agriculture as its main activity.
The use of the local KAU as the basic unit for the agricultural industry entails recording non-agricultural secondary activities where they cannot be distinguished from the main agricultural activity (inseparable non-agricultural secondary activities of local agricultural KAUs). The selection criterion for inseparable non-agricultural secondary activities is rather the type of activity than the nature of the product. For example, agro-tourism services provided by a farm are only included if they cannot be separated from its agricultural activities.

3.6. Statistical population

The agricultural industry includes all local KAUs at local level which perform the economic activities, as principal or secondary activity corresponds to Division 01 in NACE Rev. 2.1 (cf. 1.60 to 1.66 of EAA Reg.)

3.7. Reference area

The entire territory of the country.

3.8. Coverage - Time

Coverage period starting from 1980.

3.9. Base period

10.7. Quality management - documentation

Quality management for the EAA is not documented separately. Relevant quality and methodological aspects are covered by the National Accounts documentation published by Statistics Portugal and outlined in sections 11.1 and 11.2.

11.1. Quality assurance

Statistics Portugal operates under an Integrated Management System certified according to the NP EN ISO 9001:2015 standard, covering the production and dissemination of official statistics. Quality assurance is an integral part of this system and is embedded in the statistical production process, which includes the compilation of National Accounts (NA).
The NA compilation is supported by systematic validation procedures applied at different stages of the production cycle, ensuring internal consistency, coherence, and reliability of the results. A key element of this process is the annual compilation of the Supply and Use Tables (SUT), which allow for the integration of all relevant data sources, systematic validation of information, and consistency checks across National Accounts outputs.
As a satellite account of the National Accounts, the Economic Accounts for Agriculture (EAA) fully comply with the same quality requirements and validation framework.
In accordance with ESA 2010 and Regulation (EC) No 223/2009 on European statistics, the quality of national and regional accounts data transmitted to Eurostat is assessed following the modalities and indicators defined in Commission Implementing Regulation (EU) 2016/2304. Quality is ensured through the strict application of ESA 2010 concepts and methodologies and compliance with the ESS Handbook for Quality Reports.
During the compilation process, EAA data are subject to several types of quality checks, including ex ante validation of source data, ongoing checks of results, ex post assessment of methods, and external validation by Eurostat. In addition, regular exchanges with Eurostat contribute to methodological clarification and continuous quality improvement.

11.2. Quality management - assessment

The quality management assessment of the Economic Accounts for Agriculture (EAA) in Statistics Portugal focuses on evaluating the appropriateness of agricultural source data, methodological choices, and the coherence of EAA results with the National Accounts framework, in particular with Agricultural Output aggregates.
At national level, EAA quality management is assessed through internal reviews and management oversight, ensuring compliance with ESA 2010 requirements and alignment with the European Statistics Code of Practice. Particular attention is given to the consistency of EAA results over time and to their integration within Supply and Use Tables.
At European level, the assessment of EAA data is carried out through regular exchanges with Eurostat within National Accounts coordination fora. In these contexts, EAA methodologies, data consistency, and transmission practices are reviewed. Statistics Portugal’s EAA data have received favourable assessments, confirming their methodological soundness and coherence with EU requirements. While detailed assessment reports are not publicly available, their outcomes are reflected in the validation of data transmissions and the absence of significant comments at EU level.

12.1. Relevance - User Needs

The following information results from the analysis of requests for information on the EAA.The main users of the EAA data were a Portuguese statistical data platform (“PORDATA”), the Ministry of Agriculture, journalists, and students.
The following information needs were recorded:
Doubts of a conceptual and methodological nature - coverage of EAA, units considered in the agricultural activity, etc.
Doubts of a methodological and practical nature regarding the relationship and articulation between EAA, National Accounts and Quarterly Accounts - differences and articulation between a satellite account and the framework of national accounts, accounting of wine and olive oil production, etc.
EAA data breakdown and detail requests - breakdowns that are not foreseen in the EAA or cannot be calculated due to lack of basic information (other goods and services of intermediate consumption is the main request), information not foreseen in the EAA context; like agricultural crop accounts (crop production accounting by ha), etc.

12.2. Relevance - User Satisfaction

In accordance with the internal dissemination policy, responses to requests for information must be sent within 2/3 working days (maximum 5 working days). However, the internal guidance in force determines the reduction of this period, whenever possible, preferably so that the response is given on the same day. The possibility of having more detailed information online has been evaluated.

12.3. Completeness

15.3. Coherence - cross domain

EAA data are compared with other statistics, namely: National Accounts, Simplified Business Information, Farm Structural Surveys, Agricultural census.
Comparison with National Accounts is made on annual basis; for final data, through bridge tables that are regularly sent to Eurostat. Figures are identical (except for conceptual differences stated by EAA regulation).

15.3.1. Coherence - sub annual and annual statistics

Not applicable (EAA do not produce sub annual data).

15.3.2. Coherence - National Accounts

In Statistics Portugal, the EAA and the National Accounts (NA) are closely linked, being elaborated in an articulated and integrated way. Due to the calendar of each statistical operation, and because the EAA have specific sources for the agricultural activity, EAA data are used in the compilation of NA, Branch 01. However, when the definitive EAA data are calculated, they assume the final version of the NA (bearing in mind the conceptual differences).

15.4. Coherence - internal

In Statistics Portugal, the EAA and the National Accounts (NA) are closely linked, being elaborated in an articulated and integrated way, in the same Department.

Presenting the costs of EAA for a calendar year, or comparing the EAA costs between two years, may not be fully adequate measures to assess the effort or the efficiency to produce this statistic. Tasks carried out are not identical in all years and, consequently, the costs of EAA in different years reflect different realities (e.g., benchmark year revision, replies to Eurostat on ongoing studies and developments, etc.). Since EAA are derivative statistics in Portugal, burden reduction is not specific for these statistics. However, at Statistics Portugal level, measures have been taken to reduce the statistical burden on respondents, such as: more intensive use of sources of information with administrative data, simplification of questionnaires, more user-friendly questionnaires, easier data transmission, etc.

17.1. Data revision - policy

Revision policy aimed at ensuring the transparency of disseminated data. Chapter 8 of the EAA manual provides guidelines for a harmonised revision policy for EAA, including the ALI data.

17.2. Data revision - practice

In normal subsequent years, only regular revisions, and data sources’ updates, according to regular respective timetables, take place.
The EAA follows Eurostat's rules for data production, updating, and transmission in line with the EAA Regulation and its established practices.

17.2.1. Data revision - average size

Average of absolute revision is the average of absolute revisions for the years referring between the current quality (2023) and the 5-years' earlier.
