Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
The variables collected on accidents at work include all variables described in the metadata at EU level, except:
- Variables on causes and circumstances of the accident: workstation.
On the Portuguese website, data are disseminated in two forms: a synthesis of results (PDF format) and a publication of tables (PDF and XLS format).
The summary of results presents the main indicators for the reference year and the series for the earlier years broken down in some cases by economic activity (CAE Rev 3) and sex.
The publication of tables has five main groups each one with a set of tables:
1) Characterization of the enterprise: economic activity, size, geographical location;
2) Characterization of the victim: sex, age, nationality, employment status, occupation;
3) Characterization of the accident: economic activity, geographical location; date, time.
4) Characterization of the causes and circumstances: working environment, Working process, specif physical activity, material agent of the specif physical activit, deviation, material agent of the deviation, contact, material agent of the contact.
5) Characterization of the consequences: severity of the accident, days lost, type of injury, part of body injured.
In some cases data are broken down by: size of the enterprise, economic activity, geographical location, sex, age, employment status, occupation, severity of the accident.
Data is presented only in form of numbers, percentages or incidence rates of non-fatal and fatal accidents at work. The definition of these indicators is the same as at EU level.
The reference population (or number of persons in employment) related to the national ESAW reporting system is provided from the EU Labour Force Survey (LFS) (http://ec.europa.eu/eurostat/web/lfs/overview).
3.2. Classification system
At national level classifications equivalent to EU classifications are used:
CAE Rev. 3: 3nd revision of the Statistical Classification of Economic Activities managed by National Statistical Institute (INE). CAE Rev. 3 is used from reference year 2008 onwards;
CPP 2010: Portuguese classification of occupations managed by National Statistical Institute. CPP 2010 is used from reference year 2010 onwards;
NUTS version in force
ICSE-93 (International Classification of Status in Employment 93)
3.3. Coverage - sector
Until reference year 2009 (incl.): Sectors A, B, C - N;
Reference years 2010 to 2012 (incl.): All sectors except O, P and Q;
Reference year 2013 onwards: All sectors.
Because of confidentiality rules, a part of the sector O (NACE 8422 with ISCO 00 - Armed Forces occupations) is not included.
On the Portuguese website, the data tables published cover all the branches available in a given year. From 2013 onwards all sectors are covered.
Portugal sends data on accidents for all employment types, including for employees and the optional types self-employed, family workers and others.

7.2. Confidentiality - data treatment
Portugal applies the following rules:
direct identifiers are discarded in microdata files, as well as indirect identifiers when a risks for identification exists;
cell suppression and recodification of variables are applied when estimating totals and derived indicators where the frequency of the cells is less than 3 cases.
8.1. Release calendar
Data are usually released at the same time when sent to Eurostat.
In the beginning of each civil year the Office releases a calendar with the expected dates for the release of all the statistical operations.
This calendar is published on the website of the Office.
No additional information to the metadata on EU level available. Information corresponds to the EU metadata.
11.2. Quality management - assessment
The main current issue of Portuguese ESAW data is a delay in transmitting data within 18 months after the end of the reference period due to two main problems: (i) timely, correct and complete information provided by the insurance companies, and (ii) lack of human resources. Particular difficulties in this respect are the exclusion of commuting accidents from the data and the reduction of the number of unknown values in some variables.
The main strengths of Portuguese ESAW data are the other quality aspects of the data transmitted: very few errors, good reporting and coverage and the amount and quality of data provided on voluntary basis (optional employment types and others).
12.1. Relevance - User Needs
The main users of accidents at work data at a national level are:
Other national organisations concerned with health and safety at work;
Other authorities such as labour ministries, labour inspectorates, health authorities, road traffic authorities etc;
Researchers and students;
Media;
Social partners.
The Office regulary meets other national organisations or authorities, business associations, workers and employer associations as well as with researchers and students.
Information about user needs is typically collected through working groups, requests, user feedback (by satisfaction surveys or other forms), meetings and conferences.
12.2. Relevance - User Satisfaction
The views and opinions of the users are collected by satisfaction surveys, requests and complaints received, feedback from other national offices and organizations, and website accesses.
This Office intends to regularly disseminate information on this on its website.
12.3. Completeness
Portugal provides data for all the phases I and II variables (mandatory and optional) and for 6 of the 9 phase III variables (only 3 are mandatory).
12.3.1. Data completeness - rate
Portugal provides data for all the phases I and II variables (mandatory and optional) and for 8 of the 9 phase III variables (only 3 are mandatory).
Portugal also plans to increase the sample size for improving analysis, as well as the coding and recording of some variables.

Codes:
N sector not covered by data collection UNK sector covered but unknown reporting level (value %) reporting level (e) rough estimate (instead of "medium" or "high")
Explanation: Please fill in every cell with information, either "N" for sector not covered by the data collection, "UNK" for sectors covered but unknown reporting level, or a percentage value for sectors covered for which the reporting level is known (such as "52%"). Instead of "medium" or "high" please fill in a approximate value and flag it with "(e)" at the end, such as "50% (e)". Please fill in both, the global reporting cells and the detailed rows for individual sectors. If for example no sector is covered for your country, then fill into every cell "0", if all sectors are covered but all reporting levels are unknown fill in "UNK" in every cell. "N/A" should be replaced by either "N" or "UNK".
13.1. Accuracy - overall
Because the national data source for accidents are the notifications to national insurance companies, Portuguese data are considered to have high coverage and reporting levels on both, fatal and non-fatal accidents.
13.2. Sampling error
Until the reference year 2017 (included) Portugal has a data collection based on administrative registers but for some variables only a sample of non-fatal accidents is coded and registered.
From the reference year 2018 onwards, Portugal handles all data for all the variables sent and not only a sample of non-fatal accidents.
13.2.1. Sampling error - indicators
Not calculated/applicable.
13.3. Non-sampling error
Not calculated/applicable.
13.3.1. Coverage error
Until the reference year 2017 (included) Portugal may had some units accessible via the frame which do not belong to the target population (e.g. commuting accidents).
An internal analyses, comparing 2013 data results (where a sample was used) with the ones obtained in 2009 (all universe was used) allow us to calculate this over-coverage on about 0,5%.
From the reference year 2018 onwards, all commuting accidents are identified and excluded.
13.3.1.1. Over-coverage - rate
See 13.3.1.
13.3.1.2. Common units - proportion
For reference year 2018 onwards we use only administrative sources.
For reference year 2017 - Ad = 0,17 For reference year 2016 - Ad = 0,19 For reference year 2015 - Ad = 0,23 For reference year 2014 - Ad = 0,17 For reference year 2013 - Ad = 0,23 For reference year 2012 - Ad = 0,27 For reference year 2011 - Ad = 0,25 For reference year 2010 - Ad = 0,22
13.3.2. Measurement error
Portugal has no measurement available related with the errors that occur during data colection.
However, it was conducted a study with 2007 data (presented on ESAW meeting of 2011) related with the Stability (intracoder reliability) and the Reproducibility (intercoder reliability) in order to analyse the reliability of the coding process.
Those were the conclusions: - The reliability increases on average (7,5%) when going from subcategory to category level; - The NACE, Contact, Working Environment and Occupation variables are the ones with the highest coding reliabilities for both levels; - The variables with the lowest coding reliabilities are in descending order: Specific Physical Activity, Material Agent of the Contact, Deviation and Material Agent of the Deviation. - The reliability remains almost the same from the 1st to the 2nd coding. The stability is very high; - The “more” and “less” reliable variables keep the same order in the ranking.

15.3. Coherence - cross domain
Portugal did not detect any constraints on the coherence.
15.3.1. Coherence - sub annual and annual statistics
The cohere is the same as at EU level. In addition, national data may be compared with relevant data from the Unique Report - Annual Report on Health and Safety at Work (Annex D) which is an administrative source including data from all enterprises with at least one employee.

18.1. Source data
From the reference year 2013 onwards Portuguese data is based on two administrative sources: (i) private employers declarations of accidents at work to an insurance company, and (ii) public employers declarations to the competent national authorities (in this case, a public employer may transfer the responsability to an insurance company).
Both sources are primarily used for managing the consequences of accidents and only second for statistical purposes.
The main problem in data processing was the use of paper instead of an electronic register. Therefore only a sample of non fatal accidents was coded and registered for some variables.
From the reference year 2018 onwards, Portugal handles all data for all the variables sent and not only a sample of non-fatal accidents.
The reference population comes from the Labour Force Survey.
18.2. Frequency of data collection
Annual.
18.3. Data collection
ESAW data are extracted from relevate national database according to ESAW concepts, definition, variables and classifications (see also section 18.1 - Source data above).
18.4. Data validation
Portugal uses various automatic and manual checks in order to identify: (i) missing accidents, and (ii) possible errors and inconsistencies with the ESAW methodology.
Validation activities for detecting (i) missing accidents involve checks on population coverage and reporting levels. They includes:
Register all accident numbers provided in paper declarations;
Crosscheck with the accident number that is later provided by the closing map.
Validation activities for detecting (ii) possible errors and inconsistencies in the data includes:
Completeness of data files transmitted (variable fields);
Correctness of codes for each variable;
Cross validation between codes used in two or more variables;
Compare data over several years;
Coverage of variables, sectors of economic activity, employment types, sex, age and other breakdowns;
Consistency of totals and various breakdowns.
Until the reference year 2017 (included) Portugal codes and registers only a sample of non-fatal accidents for some variables. For these cases weights are provided.
From the reference year 2018 onwards, Portugal handles all data for all the variables sent and not only a sample of non-fatal accidents.
18.5. Data compilation
Until the reference year 2017 (included) Portugal codes and registers only a sample of non fatal accidents for some variables (for these cases weights are provided).
All fatal accidents and non-fatal accidents at work that took place abroad as well as all accidents which occurred in the Autonomous Regions of Azores and Madeira are fully coded, registered and analysed. The analysis of non-fatal accidents which occur on Portugal mainland uses a sample of about 20% of all cases.
Poststratification is used for the related estimation procedure. For this, the set of non-fatal accidents is decomposed into strata according to the following variables:
Type of injury: 3-digit version of the ESAW classification
Part of body injured: 2-digit version of the ESAW classification.
Days lost (severity): classes 0, 1-3, 4-6, 7-13, 14-20, 21-29, 30-90, 91-180, and 181 or more days of absence from work.
These three variables are known for all accident cases in the data set.
Assuming the following notation:
i → Type of injury: 3-digit version of the ESAW classification
j → Part of body injured: 2-digit version of the classification
k → Classes of 'days lost' (Severity)
The estimator of the population total for the variable X in stratum h= ( i, j,k) is given by:
where:
Nh - number of accidents of the population in stratum h
nh - number of accidents in the sample in stratum h
xhl - the value obtained for the item X in the l accident in the sample, l=1,…,nh
whl - weight related to the accident l of stratum h, whl = Nh/nh, l =1, ..., nh
For all fatal accidents and non-fatal accidents at work abroad and in the Autonomous Regions of Azores and Madeira the weight is 1.
From 2018 reference year onwards Portugal handles all data for all the variables sended and not only a sample of non fatal accidents.
The variables collected on accidents at work include all variables described in the metadata at EU level, except:
- Variables on causes and circumstances of the accident: workstation.
On the Portuguese website, data are disseminated in two forms: a synthesis of results (PDF format) and a publication of tables (PDF and XLS format).
The summary of results presents the main indicators for the reference year and the series for the earlier years broken down in some cases by economic activity (CAE Rev 3) and sex.
The publication of tables has five main groups each one with a set of tables:
1) Characterization of the enterprise: economic activity, size, geographical location;
2) Characterization of the victim: sex, age, nationality, employment status, occupation;
3) Characterization of the accident: economic activity, geographical location; date, time.
4) Characterization of the causes and circumstances: working environment, Working process, specif physical activity, material agent of the specif physical activit, deviation, material agent of the deviation, contact, material agent of the contact.
5) Characterization of the consequences: severity of the accident, days lost, type of injury, part of body injured.
In some cases data are broken down by: size of the enterprise, economic activity, geographical location, sex, age, employment status, occupation, severity of the accident.
Data is presented only in form of numbers, percentages or incidence rates of non-fatal and fatal accidents at work. The definition of these indicators is the same as at EU level.
The reference population (or number of persons in employment) related to the national ESAW reporting system is provided from the EU Labour Force Survey (LFS) (http://ec.europa.eu/eurostat/web/lfs/overview).
28 June 2024
At national level, Portugal provides information for all accidents (including the ones with 3 or less days of absence from work).
Between 2009 and 2018 Portugal sends information of: - All 15 phase I and II variables; - Six of the nine phase III variables on causes and circumstances: Working Environment, Specific Physical Activity, Deviation, Material Agent associated with the Deviation, Contact - mode of injury, Material Agent associated with the Contact - Mode of injury.
From 2019 onwards Portugal sends information of: - All 15 phase I and II variables; - Eight of the nine phase III variables on causes and circumstances: Working Environment, Working Process, Specific Physical Activity, Material Agent associated with the Specific Physical Activity, Deviation, Material Agent associated with the Deviation, Contact - mode of injury, Material Agent associated with the Contact - Mode of injury.
Data are collected for each accident.
If a person is a victim of more than one accident during the reference year, several cases are reported (one for each accident).
If there are several victims in the same event of accident, also several cases are reported (one for each victim).
Portugal sends data on accidents of all employment types, including optional ones.
Because of confidentiality rules, a part of sector O (NACE 8422 with ISCO 00 - Armed Forces occupations) is not included.
Data are available for all national regions (including islands) and also for Portuguese workers abroad.
No additional information to the metadata on EU level available. Information corresponds to the EU metadata.
Because the national data source for accidents are the notifications to national insurance companies, Portuguese data are considered to have high coverage and reporting levels on both, fatal and non-fatal accidents.
Portugal uses all standard ESAW statistical indicators (measurement units) except standardised incidence rates.
Until the reference year 2017 (included) Portugal codes and registers only a sample of non fatal accidents for some variables (for these cases weights are provided).
All fatal accidents and non-fatal accidents at work that took place abroad as well as all accidents which occurred in the Autonomous Regions of Azores and Madeira are fully coded, registered and analysed. The analysis of non-fatal accidents which occur on Portugal mainland uses a sample of about 20% of all cases.
Poststratification is used for the related estimation procedure. For this, the set of non-fatal accidents is decomposed into strata according to the following variables:
Type of injury: 3-digit version of the ESAW classification
Part of body injured: 2-digit version of the ESAW classification.
Days lost (severity): classes 0, 1-3, 4-6, 7-13, 14-20, 21-29, 30-90, 91-180, and 181 or more days of absence from work.
These three variables are known for all accident cases in the data set.
Assuming the following notation:
i → Type of injury: 3-digit version of the ESAW classification
j → Part of body injured: 2-digit version of the classification
k → Classes of 'days lost' (Severity)
The estimator of the population total for the variable X in stratum h= ( i, j,k) is given by:
where:
Nh - number of accidents of the population in stratum h
nh - number of accidents in the sample in stratum h
xhl - the value obtained for the item X in the l accident in the sample, l=1,…,nh
whl - weight related to the accident l of stratum h, whl = Nh/nh, l =1, ..., nh
For all fatal accidents and non-fatal accidents at work abroad and in the Autonomous Regions of Azores and Madeira the weight is 1.
From 2018 reference year onwards Portugal handles all data for all the variables sended and not only a sample of non fatal accidents.
Software: SPSS
From the reference year 2013 onwards Portuguese data is based on two administrative sources: (i) private employers declarations of accidents at work to an insurance company, and (ii) public employers declarations to the competent national authorities (in this case, a public employer may transfer the responsability to an insurance company).
Both sources are primarily used for managing the consequences of accidents and only second for statistical purposes.
The main problem in data processing was the use of paper instead of an electronic register. Therefore only a sample of non fatal accidents was coded and registered for some variables.
From the reference year 2018 onwards, Portugal handles all data for all the variables sent and not only a sample of non-fatal accidents.
The reference population comes from the Labour Force Survey.
Annual.
Portugal publishes national data a few days after sending them to Eurostat.
Portugal sent the data until 30 June of year N+2 for the last 2 years.
Portugal has no problems with geographical comparability within the national territory.
There have been some changes related to NACE (economic activity) and ISCO (occupation):
NACE Rev 2.1 - until 2007 NACE Rev 3 - from 2008 onwards
ISCO CITP - until 2008 ISCO 88 - from 2008 until 2010 ISCO 08 - from 2011 onwards
