2.1. Data description | |||
“Índice de Custo do Trabalho" is provided to Eurostat according to regulation No 450/2003 of the European Parliament and the Council of 27 February 2003 concerning the Labour Cost Index (LCI). "The objective of this Regulation establishes a common framework for the production, transmission and evaluation of comparable labour cost indices in the Community. Member states shall produce labour cost indices for the economic activities defined in article 4."
Concept, definition: the methodology corresponds to the target methodology of the European Labour Cost Index. The data include wages and salaries [basic salary, regular and irregular bonuses and allowances, overtime payment, payment and benefits in kind (not including canteens, medical centres and Christmas parties), employer's contributions (employer's social security contributions and compulsory insurance for accidents and occupational diseases) and collectively agreed, contractual and voluntary costs (supplementary pension/invalidity benefit, health insurance, life/personal accident insurance, and social benefits paid directly to employees in case of absence on account of sickness).
Statistical concept: The Labour Cost Index is defined as a Laspeyres index of labour costs per hour actually worked, annually chained, based upon a fixed structure of economic activity at NACE Rev.2, section level.
Labour cost categories are defined as indicated in the regulation (EC) Nº 450/2003 of 27 February 2003 (Total labour costs, Wages and salaries, Employer's social contributions, Total labour costs excluding bonuses).
With the publication of the results for the 1st quarter of 2020, Statistics Portugal started to include, in the LCI calculation, regarding the information related to the labour costs obtained from administrative sources, data corresponding to the universe of about 386 thousand entities (instead of the sample of around 3 800 entities), which declared earnings for a total of 4.2 million workers. In 2023, the information gathered from administrative sources corresponds to the universe of approximately 437 thousand entities which declared earnings to Social Security and to Caixa Geral de Aposentações, for a total of around 4.5 million workers. The information on hours actually worked continues to be obtained by direct inquiry from the entities that belong to the LCI sample (4 270 entities in 2023), and no changes were introduced at this level. For the O, P and Q sections of NACE-Rev.2, estimates of the number of hours actually worked per employee from the Labour Force Survey are used. In 2020, the weight structure for 2018 was updated due to the appropriation of administrative data on labour costs concerning the universe. The data collection for the new series of the LCI covered the four quarters of 2018, to guarantee the comparable basic information for the index computation from the 1st quarter of 2019. Since the publication of the indices for the 1st quarter of 2019, the observation unit is the enterprise instead of the local unit.
With the publication of the results for the 1st quarter of 2023, the Labour Cost Index series (2016=100) were rebased to the year 2020 (2020=100), in line with Eurostat’s procedure for the Labour Cost Index, whenever more up-to-date data of the (quadrennial) Labour Cost Survey become available.
The back series for all indices, from the 1st quarter of 2008, are available at the Official Statistics website.
For this series a new sample was extracted from the "reference population for surveys on enterprises" of Statistics Portugal, being this the sampling frame for the LCI (base 2020). This sample is renewed every year.
The weight structure used in the aggregation of economic activities was updated, resulting from changes in the economy's sectoral composition between 2021 and 2022.
Labour Cost Survey (LCS) data are used to obtain information that are representative of the universe of enterprises between one and nine employees for the hours actually worked as the LCI direct and regular collection is addressed only to enterprises with ten or more employees in order to minimize the statistical burden on enterprises. The LCS is also used to obtain information for the variables that are not available in the administrative sources, namely insurance against accidents and occupational diseases, supplementary pension/invalidity benefits, health insurance, life/personal accident insurance and social benefits paid directly to employees in case of absence on account of sickness.
Data collection for data on hours is carried out through an electronic questionnaire over the Internet (WEBINQ).
Vis-à-vis the statistical operation for the base year 2016 the following remained unchanged:
• The legal framework– basic Regulation [Regulation (EC) No 450/2003 of the European Parliament and of the Council of 27 February 2003] and following, setting forth:
• The concepts regarding the various labour cost items and the hours actually worked.
• The technical specification of the index (Laspeyres index).
• The economic activities covered: activities from Sections B to S of NACE-Rev.2.
• The quarterly frequency.
As mentioned before, complementary statistical sources are used to ensure compliance with the principle of administrative simplification. These sources are the Labour Force Survey and the Labour Cost Survey 2020 to obtain the hours actually worked for the public administration and, the correction factors to get estimates for hours actually worked for enterprises between one and nine employees, respectively.
|
|||
2.2. Classification system | |||
NACE Rev.2 Data is compiled and provided to Eurostat for the following aggregates: Total labour costs, wages and salaries, other costs, and total labour costs excluding bonuses; Unadjusted data, calendar adjusted data (not seasonally adjusted data), calendar, and seasonally adjusted data. |
|||
2.3. Coverage - sector | |||
Sections B to S of NACE Rev.2 Data on labour costs are obtained from administrative sources. All size classes are covered, as well as the private sector and the public administration [Sections O (Public administration and defence; compulsory social security) and the public part of Sections P(Education) and Q (Human health and social work activities). Labour costs incurred by the employer corresponds to that reported by the entities to the Social Security (Declaração Mensal de Remunerações) and to the Caixa Geral de Aposentações (Relação Contributiva). The information on hours actually worked is obtained by direct inquiry from a sample, through the quarterly survey "Índice de Custo do Trabalho" and covers enterprises with at least ten employees. For the O, P and Q sections of NACE-Rev. 2 estimates of the number of hours actually worked per employee from the Labour Force Survey are used. LCS data are used to obtain information on the hours actually worked that are representative of the universe of local units, namely, to produce estimates for enterprises between one and nine employees, as the LCI direct and regular collection is addressed only to enterprises with ten or more employees. Annexes: Number of employees by sections of NACE Rev.2 |
|||
2.4. Statistical concepts and definitions | |||
Number of employees: the persons who during the reference period participated in the business of the enterprise/institution, regardless of the duration of this participation, under the following conditions: a) staff bound to the enterprise/institution by an employment contract, receiving remuneration in return; b) staff which has ties to the enterprise/institution, who, for not being bound by an employment contract, does not receive regular remuneration for the hours worked or the labour supplied (e.g. owner-managers, unpaid family workers, active members of cooperatives); c) staff with ties to other enterprises/institutions who worked at the enterprise/institution and receive remuneration directly from it; d) persons in the above situations, absent for a period of no more than one month due to holidays, labour dispute, vocational training, as well as disease and occupational accident. The following persons are not considered to be staff: i) those in the situations described in a), b), and c) above and who are absent for a period of over one month; ii) workers with ties to the enterprise/institution who moved to other enterprises/institutions, receiving remuneration directly from the latter; iii) workers in the enterprise/institution whose remuneration is borne by other enterprises/institutions (e.g. temporary workers); iv) self-employed workers (e.g. service providers, that use the so-called 'recibos verdes', which is the popular name of the receipt form). Hours actually worked: the total number of hours that employees on service actually worked. It includes extra hours. It also includes time spent at the place of work on tasks such as preparing work instruments, preparing, and servicing tools, paid dead time at work, time due to sporadic absences from work, the stoppage of machinery or accidents and short coffee breaks. Absence from work is excluded, irrespective of whether it is paid or not. Compensation of employees: The compensation of employees is defined as the total remuneration, in cash or in kind, payable by an employer to an employee in return for work done by the latter during the reference period. The components are:
Taxes paid by the employer: All taxes based on the wages and salary bill or on employment. Subsidies received by the employer: All amounts received in the form of subsidies of a general nature intended to refund part or all the cost of direct remuneration but not intended to cover social security or vocational training costs. It does not include refunds paid to the employer by social security institutions or supplementary insurance funds. |

|
|||
3.1. Source data | |||
The origin of basic data (labour costs) is mainly from an administrative source, namely data provided by the enterprises to the Social Security and by the Public Administration organization to Caixa Geral de Aposentações. The hours actually worked (as well as the number of employees, in order to guarantee consistency) remain collected through the quarterly survey "Índice de Custo do Trabalho" where the statistical unit is the enterprise. For the O, P and Q sections of NACE-Rev.2 estimates of the number of hours actually worked per employee from the Labour Force Survey are used. Types of data: Basic types of data are basic wages and salaries, regular and irregular bonuses and allowances, overtime payment, payments in kind, employers’ statutory social contributions, collectively agreed, contractual and voluntary costs and others. Hours worked involve hours actually worked by employees during normal working hours and overtime. Main internal data sources: Hours actually worked are collected through the quarterly survey “Índice de Custo do Trabalho” where the statistical unit is the enterprise. This sample survey is used to collect data on the number of hours worked, the hours not worked and overtime hours to compile the hours actually worked. Data are collected through an electronic questionnaire over the internet (WEBINQ). For the O, P and Q sections of NACE-Rev.2 estimates of the number of hours actually worked per employee from the Labour Force Survey are used. Main external data sources: - Data provided by the enterprises to the Social Security and by the Public Administration organization to Caixa Geral de Aposentações. - Labour Cost Survey. |
|||
3.2. Frequency of data collection | |||
The quarterly survey “Índice de Custo do Trabalho” collects data on the number of hours worked, the hours not worked and, overtime hours. Administrative data are reported monthly. |
|||
3.3. Data collection | |||
The LCI is a statistical operation held on a quarterly basis through a sampling survey to collect information on hours. Data collection is carried out through an electronic questionnaire (Computer Assisted Web Interviewing - CAWI). By economic activity, the LCI covers Sections B to S of NACE-Rev.2. For the O, P and Q sections of NACE-Rev.2, estimates of the number of hours actually worked per employee from the Labour Force Survey are used. Base period: electronic questionnaire over the internet (WEBINQ). Quarterly updates: electronic questionnaire over the internet (WEBINQ). Reference period of data collection on hours: the second month of each quarter (February, May, August, and November). Administrative sources: data on labour costs reported monthly by the enterprises to the Social Security and by the Public Administration organisations to Caixa Geral de Aposentações.
|
|||
3.4. Data validation | |||
The quarterly labour cost components data from administrative sources are validated. The components of hours (duration of work, number of hours worked, the hours not worked and overtime hours) that are collected using the "Índice de Custo do Trabalho" survey are also validated. Detailed validation criteria (Service levels) are agreed between the unit responsible for the compilation of the LCI and the unit responsible for the data collection. Domain, coherence, and structure validations are carried out at the time of the data collection and entering of the data to identify eventual inconsistencies. After the data collection and the data entry new validations are made in accordance with the rules previously defined to evaluate possible discrepancies (such as reasonability of the magnitude of some ratios, comparison with the levels observed in previous periods, cross checking of the variables). If necessary, the respondents are contacted by the Data Collection and Management Department to clarify or to confirm the data. Similar validations are performed for the administrative data, especially for the average remuneration and the rate of contribution. Final data is also carefully assessed and confronted against the results of other short-term indicators, such as employment, wages and hours worked in industry, construction, and services as well as data from the Labour Force Survey. |
|||
3.5. Data compilation | |||
The LCI is a short-term indicator that measures quarterly developments in labour costs per hour actually worked (hourly average cost) incurred by the employer. The index is calculated by dividing the average cost per employee by the number of hours actually worked per employee. For this reason, the evolution of these two variables (labour costs and hours worked) contributes to explaining developments in the LCI. Labour costs incurred by the employer include the following: Wage costs:
Other costs:
The components of hours worked are as follows:
Hours actually worked The number of hours actually worked are obtained as follows: Potentially hours worked in the quarter – Nonworking time held in the quarter + overtime
The variables on duration of work (paid and unpaid) are collected for the reference month of the quarter and then transformed into quarterly data before carrying out the calculations.
Administrative data Information related to the labour costs components are obtained from Social Security and Caixa Geral de Aposentações. Base year: 2020 . The choice of this year was based as usual on the reference year for the last available data from the Labour Cost Survey (LCS), conducted every four years. LCS data are used to obtain results that are representative for the universe of enterprises with one or more employees, given that the LCI direct and regular data collection of the hours worked is addressed only to the enterprises with ten or more employees to minimize the statistical burden on enterprises. Quarterly updates: They are done through the quarterly LCI survey to collect components on hours. The sample in force in the statistical operation for the base year 2020 was extracted from the “reference population for surveys on enterprises” of Statistics Portugal. This sample is renewed every year. The compilation of the LCI by economic activity (NACE-Rev. 2) is essentially carried out in five steps. 1. Obtain of labour costs and the estimates of hours actually worked (generically referred to as Y variable below) by stratum. Considering: i: economic activity of the enterprise j: region of the enterprise k: size class of the enterprise h: stratum defined by the crossing of the variables economic activity, region, and size class the estimator of the total of the variable Y in the stratum h = (I, j, k) is given by:
Υ = Xh / xh ∑ Υhe, where ∑ between e=1 to nh
where: Xh: number of persons of the population in stratum h xh: number of persons of the answers (sample) in stratum h e: enterprise belonging to stratum h of the sample nh: number of enterprises that answered in stratum h Yhe: variable value X in enterprise e from stratum h 2. Once the strata are independent, estimates of hours actually worked by economic activity and region are given by the sum of the estimates of the strata that compose them. 3. Estimates on hours actually worked relate to enterprises with one or more persons. Once the sample of the LCI covers enterprises with 10 or more employees and Regulation (EC) nº 450/2003 of 27 February requires the coverage of all size enterprises, correction factors obtained from LCS 2020 are applied. Note that the LCS 2020 collects data for local units of all sizes, being compiled separately for establishments with “one or more persons” and “ten or more persons”. The correction factors for hours actually worked are obtained by dividing the values of the variables corresponding to “one and more persons” and “ten or more persons”. 4. Integration of information related to the Labour Force Survey: estimates of the number of hours actually worked by employees for the O, P and Q sections. 5. After applying the correction factors to the data collected through the LCI survey and integration of information on hours actually worked for Public Administration, the final step is the calculation of the indices.
|
|||
3.6. Adjustment | |||
Working Days Adjusted data To obtain the working days adjusted series, an adjustment factor is applied to the number of hours actually worked per employee. Adjustment factor = number of working days in each quarter /number of working days in the corresponding quarter of the base year. This factor is applied for NACE sections data.
Seasonal Adjusted data Working days adjusted series are used to obtain seasonally adjusted series. Seasonal adjustments are made using Tramo-Seats (Demetra sofware). Under this method, the seasonal adjustment includes two phases. In the first phase, is made a pre-adjustment of the series in Tramo. In the second phase, the method Seats seasonal adjustment is applied. This method belongs to the family of parametric methods of seasonal adjustment, based on stochastic econometric models (ARIMA models). The choice of the specification of the models is done automatically. For calendar adjusted and seasonal adjusted data, the indirect method is applied to guarantee consistency in the aggregations. This is performed deriving the unchained LCI for totals from the unchained LCI of the wage and non-wage components. For the LCI 2020 series the indirect method was applied also to the unadjusted data. |
|
|||
4.1. Quality assurance | |||
Parameter variations are defined for each variable. For each variable, levels of service are defined, ranging between 90% and 95%. |
|||
4.2. Quality management - assessment | |||
For each variable of the questionnaire ranges were defined. Surpassing the limits, the data should be checked, changed and/or justified by the enterprise. |
|
|||
5.1. Relevance - User Needs | |||
Eurostat/European Central Bank Both are the main regular users of LCI. Among other tasks, the Bank of Portugal disseminates the “main economic indicators” for the EURO zone. Statistics Portugal provides information for wage costs for the total economy and for industry (SDDS). Enterprises Enterprises from several sectors of activity use the LCI indicators to follow the effects of labour and monetary policies on labour costs, to forecast and to plan the evolution of wages and personnel costs, as well as an element for indexing the value of contracts for the provision of services. Departamento de Contas Nacionais (National Accounts Department). Other external users Satisfaction of the users’ needs Sometimes other users (journalists) ask for long series. |
|||
5.2. Relevance - User Satisfaction | |||
To evaluate the user satisfaction there are the following questionnaires in Statistics Portugal:
In these surveys results, there are no information on the satisfaction of the use of "Índice de Custo do Trabalho" data. Only on the subject where it is integrated, labour market. There are no specific indications for "Índice de Custo do Trabalho". |

Working Days Adjusted data To obtain the working days adjusted series, an adjustment factor is applied to the number of hours actually worked per employee. Adjustment factor = number of working days in each quarter /number of working days in the corresponding quarter of the base year. This factor is applied for NACE sections data. Seasonal Adjusted data Working days adjusted series are used to obtain seasonally adjusted series. Seasonal adjustments are made using Tramo-Seats (Demetra sofware). Under this method, the seasonal adjustment includes two phases. In the first phase, it is made a pre-adjustment of the series in Tramo. In the second phase, the method Seats seasonal adjustment is applied. This method belongs to the family of parametric methods of seasonal adjustment, based on stochastic econometric models (ARIMA models). The choice of the specification of the models is done automatically. The template for quality reporting on Seasonal Adjustment of the LCI is duly filled with the results for NACE sections B to S obtained through the JobVacancySurveyQR plugin. Please note that the lines for activity aggregations have not been filled since they are obtained through the indirect method, outside of Demetra. Only the elementary indices (activity sections) are handled in Demetra. Annexes: Quality reporting on SA |
|||
6.5. Data revision - policy | |||
At national level, there is not a schedule for data revision. The revisions result from the inclusion of information for the last quarter sent lately by some enterprises of the sample survey on hours worked and from the update of information obtained through administrative sources, namely by data from the Declaração Mensal de Remunerações reported monthly by the enterprises to the Social Security.
Annexes: Labour Cost Index and year-on-year growth rates (NSA) for NACE sections B to S |
|||
6.6. Data revision - practice | |||
The data published in release "Destaque" concerning the last quarters are subject to revisions. These revisions result, on one side, from the inclusion of information for the last quarter sent lately by some enterprises of the LCI sample and, on the other side, from updates of information obtained through administrative sources, namely by data from the Declaração Mensal de Remunerações reported monthly by the enterprises to the Social Security. With the publication of the results for the 1st quarter of 2020, Statistics Portugal started to include, in the LCI calculation, regarding the information related to the labour costs obtained from administrative sources, data corresponding to the universe of about 386 thousand entities (instead of the actual sample of 3800 entities), which declared earnings for a total of 4.2 million workers. In 2023, the information gathered from administrative sources corresponds to the universe of approximately 437 thousand entities which declared earnings to Social Security and to Caixa Geral de Aposentações, for a total of around 4.5 million workers. The information on hours actually worked continues to be obtained by direct inquiry from the entities that belong to the above-mentioned sample and no changes were introduced at this level. This change has impact in the indices released since the 1st quarter of 2019. Additionally, the LCI series have been revised in February 2021 because of the detection of a mistake in the “other costs” component since the 1st quarter of 2019. With the publication of the results for the 1st quarter of 2023, the Labour Cost Index series were rebased to the year 2020 (2020=100), in line with Eurostat’s procedure for the Labour Cost Index, whenever more up-to-date data of the (quadrennial) Labour Cost Survey become available. This procedure does not change, by definition, the year-on-year changes already published. However, this opportunity was taken to fully adjust the method for calculating the indices to the methodology adopted by Eurostat, resulting in small differences from the figures previously published. The back series for all indices, from the 1st quarter of 2008, are available at the Official Statistics website. |
|||
6.6.1. Data revision - average size | |||
These revisions result, on one side, from the inclusion of information for the last quarter sent lately by some enterprises of the LCI sample and, on the other side, from updates of information obtained through administrative sources, namely by data from the Declaração Mensal de Remunerações reported monthly by the enterprises to the Social Security. See table: Revision of the LCI year-on-year rates of change published (B_S) (working days adjusted data).

11.1. Confidentiality - policy | |||
Statistical secrecy is established by Law to safeguard the privacy of citizens in general and to ensure trust in the NSS. All personal data collected by the authorities, for statistical purposes, are considered confidential, being protected by the professional secrecy, either by employees or others who became aware of them by means of their professional duties related with the official statistical activity. The breach of confidentiality is considered a very serious administrative offence (in case of violation of professional secrecy it implies criminal responsibility), while the non-response to surveys within the period stipulated by the statistical authority is considered a serious administrative offence. The staff of Statistics Portugal signs legal confidentiality commitments on appointment. Instructions and guidelines exist for the protection of statistical confidentiality, both at concerns production and dissemination processes. The National Statistical Law nº 22/2008 of May 13, 2008, establishes the principle of confidentiality under which no individual information about people can be disseminated. Information about corporate enterprises can only be disseminated under very restrictive conditions and always requires prior consent |

Quarterly data are available/disseminate in May (Q1), August (Q2), November (Q3) and February (Q4). Reference period of "Índice de Custo do Trabalho": Q1 (February), Q2 (May), Q3 (August), Q4 (November) for hours components. The sample frame of "Índice de Custo do Trabalho" was extrated from the "reference population for surveys on enterprises" of Statistics Portugal. The stratification was the following:
With the publication of the results for the 1st quarter of 2019, Statistics Portugal starts the dissemination of a new series of the Labour Cost Index (LCI), with the base year in 2016, in line with Eurostat’s procedure for the Labour Cost Index, whenever new data of the (quadrennial) Labour Cost Survey become available. Back series for all indices analysed in this press release, from the 1st quarter of 2008, are available at the Official Statistics website. In addition to the change of the base year, in the context of the SIMPLEX+ measures, the labour costs information, which was previously collected by direct inquiry, was obtained through administrative sources, namely data reported monthly by the enterprises to the Social Security and by the Public Administration organizations to Caixa Geral de Aposentações. The number of hours worked, the hours not worked and overtime hours, however, remain to be obtained by direct inquiry. The data collection for the new series of the LCI covered the four quarters of 2018, to guarantee the comparable basic information for the index computation from the 1st quarter of 2019. The observation unit changed from local unit to enterprise. With the publication of the results for the 1st quarter of 2020, Statistics Portugal started to include, in the LCI calculation, regarding the information related to the labour costs obtained from administrative sources, data corresponding to the universe of about 386 thousand entities, which declared earnings for a total of 4.2 million workers. The information on hours actually worked continues to be obtained by direct inquiry for a sample and no changes were introduced at this level. This change has impact only in the indices published as of the 1st quarter of 2019. With the publication of the results for the 1st quarter of 2023, the Labour Cost Index (LCI) series were rebased to the year 2020 (2020=100), in line with Eurostat’s procedure for the Labour Cost Index, whenever more up-to-date data of the (quadrennial) Labour Cost Survey become available. |
