Summary of core users

The main Structure of Earnings Survey data users may be grouped as following:

(i) internal users:

  • governmental bodies: Ministry of Labour, Family and Social Protection, Ministry of Public Finances, National Commission for Prognosis, National Agency for Employment, Ministry of Education, Research, Youth and Sports, National Council for Adult Education and Training, Ministry of Public Health;
  • employers and employers’ associations;
  • trade unions;
  • professional associations;
  • research institutes and universities: Research Institute of National Economy, Research Institute for Labour Force, Research Institute for Education, Romanian Academy, Academy for Economic Studies etc.
  • mass-media;
  • students, doctorates.

 

(ii) external users:

  • European Union and international organisations: Eurostat, ILO, OECD, UNDP, World Bank, IMF;
  • foreign research institutes;
  • foreign employers.

 

Description of users needs

The Structure of Earnings Survey (SES) provides to the users important data on hourly, monthly and annually earnings, on working time, as well as on the structure of earnings. The survey results are available by multiple breakdowns on demo-socio-economical characteristics of the employees: gender, age groups, occupational groups, level of education, length in the enterprise, type and duration of the working time, economic activities, size classes of the enterprise, ownership forms.

SES is the only survey conducted at employee level, providing such amount of complex information.

Through the SES results the users can find the answers to diverse questions such as:

  • Which is the level of the hourly, monthly and annually earnings by occupation groups, sex, age groups or level of education?
  • How is the distribution of employees by sex, working program (full-time, part-time), age groups or occupation groups?
  • How many employees are working in small, medium or big enterprises from a certain economic activity?
  • What type of collective pay agreements covers the employees employed in an enterprise?
  • Which is the level of the earnings from a certain economic activity comparing with the average?

 

(i) internal users:

The SES outcomes, in relation with the information provided by other surveys, are used by policy makers at national level in establishing the actions and measures for economic development strategies as well as for implementing programs on active measures aimed to improve the employability and as for setting up the policies on wages and salaries.

 

  • Ministry of Labour, Family and Social Protection and Ministry of Public Finances are interested in the structure of earnings and the level of hourly, monthly and annually earnings by different categories of employees in relation to the financial and social protection policies.
  • Ministry of Labour, Family and Social Protection, Ministry of Public Finances and National Commission for Prognosis are paying a special attention to the structure and level of earnings. Several strategies, presently on going, are focused on:
    • equal chances for women and men in terms of remuneration and work conditions;
    • policies of the employment and qualification of labour force, especially for unfavourable groups such as young (15 – 24 years) and elderly (55 – 64 years);
    • the settlement upon the part-time work in order to adjust the working relationships to the demands of the labour market;
    • remuneration policies;
    • stimulation of employers in creating and increasing the number of new jobs.
  • Based on the SES results, Ministry of Labour, Family and Social Protection and National Agency for Employment are developing and implementing special programs with the aim of unemployment decreasing by offering special reductions on taxation and providing subsidies to the enterprises that would employ unemployed persons.
  • Special advantages were offered to the employers who were employing graduates (legal acts entered into force proposed by Ministry of Education, Research, Youth and Sports).
  • National Council for Adult Education and Training has a high interest on the employees’ qualification, skills and vocational training (i.e. the actual time spent by employees for vocational training during a year). The aim is to reach a higher qualification of the existing labour force (instead of employing directly high educated personnel), adequate to the high technologies and innovations.
  • The level and structure of earnings are of a big interest when negotiations with trade unions are held. SES results are key elements for negotiation of collective agreements in relation not only for the direct remuneration, but also for the share of payments in kind and other advantages, pension scheme, social and health insurance, programs for vocational training (improvement of level of qualification etc.).
  • Employers (enterprises), employers’ associations and professional associations are carrying out several comparative analyses of the monthly earnings among economic activities, economic and financial control, occupations or levels of education.
  • Research institutes and universities are interested in and are producing analysis on the level and structure of earnings among economic activities, economic and financial control, occupations or levels of education, comparisons with other countries (either EU or non-EU member states).

 

(ii) external users:

  • European Union and international organisations: are usually expressing their needs by specific regulations and agreements and through the working groups held with a given periodicity (EUROSTAT) and through international meetings and regular (for updating of databases) and ad hoc requests sent to INS (ILO, OECD, World Bank);
  • Foreign research institutes: are formulating their needs through the requests sent to INS, data being provided upon availability;
  • Foreign employers (investors) are interested in the level of earnings among economic activities for public and private sectors; upon request different levels of aggregated data can be disseminated.
5.2. Relevance - User Satisfaction

(i) internal users:

In Romania, official statistics is under the responsibility of National Institute for Statistics (INS). In order to ensure the objective and the transparent and scientific character of the methodologies, indicators and classifications used in statistics, the Council of Co-ordinating the Statistical Activity was set-up.

The Council is composed of representatives of:

  • Romanian Academy,
  • specialised higher education system and research,
  • ministries and other specialised bodies sub-ordinate to the Government,
  • Romanian National Bank,
  • trade unions,
  • employers’ associations,
  • mass-media,
  • professional associations.

 

The representatives of the Council meet quarterly or more frequently when is necessary, in working groups by statistical fields. During these meetings INS receives a strong feed-back from the users in terms of the results already disseminated (including the level of details, breakdowns etc.) and the requests for further needed information to be included in next statistical inquiries.

Before finalising the survey tools and launching any survey on wages and labour costs, INS usually consults its main users (Ministry of Labour, Family and Social Protection, Ministry of Public Finances, National Commission for Prognosis, research institutes and universities etc.) and asks for methodological approval given by the “Commission of Methodological Approval”.

The SES questionnaire, explanatory notes and annexes with classification were submitted for approval when first launched in 2002. Because no major changes occurred for the 2006 and 2010 surveys, no other methodological approval was needed.

 

(ii) external users:

  • European Union and international organisations: survey tools were designed by respecting the recommendations stated in the Commission Regulation no 1738/2005 amending Regulation (EC) no 1916/2000 as regards the definition and transmission of information on the structure of earnings; when different levels of aggregations are asked, if it is possible, data are processed accordingly or, if not, the most appropriate are given with the needed explanations;
  • Foreign research institutes: depending on the request, either data are sent in the available format either are prepared to reach as much as possible their needs;
  • Foreign employers (investors): most of their requests are satisfied by the available data.
5.3. Completeness

According to the Commission Regulation no 1738/2005 amending Regulation (EC) no 1916/2000, all UE member states had to conduct the Structure of Earnings Survey in 2010, collecting and providing to Eurostat a number of 34 variables (mandatory and optional).
Romania collected and provided 26 mandatory variables (100% mandatory variables) and 7 optional variables (88% from all optional variables), meaning 97% of all variables requested by the Commission Regulation. The only optional variable not collected was “1.7 Affiliation of the local unit to a group of enterprises”.
Apart from the variables requested by the CR, Romania introduced a number of variables for national purposes:

  • basic salary,
  • monthly and annually gross amounts from the net profit,
  • monthly and annually gross amounts from other funds, including payments in kind,
  • monthly and annually gross amounts from the insurance schemes,
  • normal duration of working month,
  • payment period,
  • annual number of days paid for sick leave (total, paid by the employer),
  • annual number of days paid but not worked due to special events,
  • annual number of days for vocational training.

 

Information collected and provided by Romania answered to Eurostat requests in terms of classifications and breakdowns:

  • geographical location - NUTS-1 level;
  • principal economic activity - NACE Rev.2 - all sections A-S (coded at division level 01-96), cluding the sections A (not requested by the regulation) and section O (optional according to the regulation);
  • size class of the enterprise – all mandatory size classes 10-49, 50-249, 250-499, 500-999, 1000 and more employees;
  • form of economic and financial control – all categories “public control” and “private control”;
  • collective pay agreement – all categories “national level”, “industry level”, “individual industries level”, “enterprise or single-employer level”, “local unit level”, “other type”, “no agreement”;
  • occupation – ISCO-08 – all occupation coded at two digit level, except major group 0 (armed forces) that are not covered by any Romanian survey;
  • level of education and training - ISCED 97 – all levels “pre-primary”, “lower and upper secondary”, “first and second stage of tertiary education”;
  • contractual working time – “full-time” and “part-time” employees;
  • type of employment contract - “indefinite duration”, “temporary/fixed duration”, “apprentice”.

 

The variables collected and provided by Romania answer to all Commission Regulation requirements, for data transmission:

  • country level and macro-region level: NUTS-0 and NUTS-1 level;
  • economic activities: section level A-S (1-digit);
  • size class of the enterprises: 10-49, 50-249, 250-499, 500-999, 1000 and more employees;-
  • categories of variables:
    • Information about the local unit to which the sampled employees are attached (1-variables),
    • Information on individual characteristics of each employee in the sample relating to the reference month (2-variables),
    • Information on working periods for each employee in the sample (3-variables),
    • Information on earnings for each employee in the sample (4-variables),
    • Grossing-up factors (5-variables)
  • categories of employees: employees and apprentices [1].

 

No compulsory breakdown, in terms of economic activities or size classes, is missing from the Structure of Earnings Survey 2010.

Furthermore, data for NACE Rev.2 section A (which is not requested by the regulation) and for section O (which continues to be optional according to the regulation) were collected and provided by Romania.

The selection of the employees in the sample was complex, done by each enterprise according to the rule recommended by INS of respecting the proportionality by sex, major groups of occupation and working program of the total number of employees of the enterprise. Thus, a clearer image of the distribution of employees from the whole enterprise was reflected by the selected sample.

Even though SES is a complex survey, considered by the respondent units a burden, since a lot of detailed and complex information for each selected employee was asked, the response rate [2] was rather high (89.20%, refusal rate 6.57%).

6.3. Non-sampling error

Detailed description in the following items.

6.3.1. Coverage error

The sampling frame used to draw the sample was built using the Romanian Business Register and contained the statistical information related to the reference period, namely the calendar year of 2010. As consequence the main over/under coverage problems are related to the information quality concerning size class of enterprises by number of employees.

In the weighting and adjustment process the unidentified units were assimilated to that of the non-respondent units The weighting procedures applied at enterprise level was done in order to compensate the total non-response, together with the calibration procedures applied at NACE. Rev. 2 division and with information on active enterprise in 2010. The auxiliary variable used for calibration was the number of persons employed (variable 16110 according to Structural Business Survey). The calibration was produced also with the routine of the CLAN programme provided by Swedish statistics.

In the table in the attached document Misclassification are presented the measure of misclassifications by size classes by number of employees and NACE Rev.2 category to 1-digit level (section).

6.3.1.1. Over-coverage - rate

A percentage of 1.67% of surveyed enterprises reported a number of employees less than the limit threshold for including criteria in the reference population (at least 10 employees) but the stability of activity is at high level (over 90%). In the meantime it encounters the existence of a 2.20% of unidentified enterprises. In the adjustment procedure the unidentified enterprises were assimilated to the non-response units.

6.3.2. Measurement error

The information given below refers only to the errors and cases corrected at central level (INS), after the data files were received from all over the country. Statistics on the first level of checking (local level) are not available.

One error might need several variables to be corrected or, if the figures correspond to reality due to unusual phenomena, figures were accepted as such and no changes were operated.

Most frequent errors that occurred during data checking period:

  • 8.64% of errors coded A113 (in Romanian Logic tests); the employee contribution for unemployment insurance should fall between 0.2% – 0.8% of the monthly gross payments related to direct remuneration;
  • 8.09% of error coded A114; the employee contribution for statutory social security should fall between 8.0% – 12.0% of the monthly gross payments related to direct remuneration;
  • 7.85% of errors coded A91-A93; the correlation among working program, period of payment and number of hours paid;
  • 7.73% of errors coded A123-A126; the correlation between the annual gross amounts paid and the monthly gross amounts multiplied with the period of time worked during the year;
  • 6.58% of errors coded A105-A108; the correlation among working program, period of payment and basic salary;
  • 5.50% of errors coded A101-A102; the correlation between the basic salary and the minimum wage (according to the national legislation in force);
  • 5.48% of errors coded A340; the correlation between number of overtime hours paid and the gross amounts paid for the overtime;
  • 5.25% of errors coded A115; the employee contribution for health insurance should fall between 4.5% – 6.5% from the monthly gross payments related to direct remuneration;
  • 4.79% of errors coded A116; the employee taxes should fall between 0.1% – 16% from the monthly gross payments related to direct remuneration (excluding the individual contributions to unemployment, social security and health insurance);
  • 4.59% of errors coded A79; if the enterprise has the economic activity of public administration, education or health and social insurance, and the employee has a managerial/supervisory position, then the occupation codes have to be from the 1st major group of ISCO-08, specific for these activities;
  • 3.45% of errors coded A83-A84; the correlation between the occupation code and managerial/supervisory position;
  • 3.10% of errors coded A80 and A338; the correlation between the occupation code and the level of education code;
  • 2.88% of error coded A147-A148; the annual of days paid but not worked due to special events;
  • 1.43% of errors coded A138; the correlation between the gross amounts paid from the insurance schemes and the annual days of sick leave;
  • 1.25% of errors coded A144-A145; the correlation between the annual number of holidays and the number of months worked.

 

The number of cases needed to be corrected was not so significant to have an impact on the accuracy of the final results. In the table below are estimated the percentages of cases corrected at central level, by collected variables.

For the microdata transmitted to Eurostat the plausibility checks were appliyed and different inconsistencies explained.

The Structure of Earnings Survey is based on a stratified sample of enterprises instead of local units due to the fact that the Business Register is not built at local unit level. The sample of employees was selected from local units belonging to the selected enterprises according to the algorithm of selection indicated in the methodological notes, part of the survey tools.

Not all the “plausibility checks” were fulfilled, but the number of these cases is not significant (representing about 1.5% from all records):

  • the cases for which the condition if var.2.7=FT, then 130 hours < (var.3.2-var.3.2.1) is not fulfilled, are accepted due to the fact that there are contracts with stipulated working time of 6 hours/day.
  • the cases for which the condition if var.2.7=FT, then (var.3.2-var.3.2.1) > 215) is not fulfilled, are accepted due to the fact that, for certain cases and occupations, the contractual working was more than 8 hours/day. All hours are paid in the reference month, but not considered overtime.
  • the cases for which the condition var.3.2.1<0.65* (var.3.2-var. 3.2.1) is not fulfilled, are accepted due to the fact that, for certain cases and occupations, the number of overtime hours paid are higher than 65% of the normal number of hours paid (but not over 90%).
  • the cases for which the condition var.4.1>(var.4.2-var.4.2.1)*0.7* var.3.1/(4.345238) is not fulfilled, are accepted due to different economical development of certain enterprises during the year (production or receipts depending on orders and contracts, seasonality) and consequently different remuneration (either higher gross amounts paid in October or lower payments according to volume of work performed in other months).
  • the cases for which the condition var.4.1.2<0.2*var.4.1 is not fulfilled, are accepted due to fact that the employees were rewarded significant payments in kind when the enterprise encountered financial difficulties. Also, there are cases where different payments in kind are stipulated in the pay agreements.
  • the cases for which the condition var.4.2>var.4.2.3 and var.4.2.3
  • the cases for which the condition If var. 3.2.1>0 and var.4.2.1>0 then (var.4.2.1/var.3.2.1)≥(var.4.2–var.4.2.1)/(var.3.2-var.3.2.1)*0.60 is not fulfilled, are accepted due to fact that the payments related to overtime are calculated in relation with the basic salary and not with the actual earnings. Also, there are different rates for the overtime payments.
  • the cases for which the condition var.4.2.3.1< var.4.2–(var.4.2.1+var.4.2.2) is not fulfilled, are accepted due to fact that the monthly gross earnings exclude the occasional bonuses, net profit and payments in kind. The compulsory social contribution and taxes paid by the employer on behalf of the employee are calculated to all gross amounts paid to the employee in month October (including occasional bonuses, net profit and payments in kind). For these cases the plausibility check is not relevant because the amounts paid for irregular bonuses and payments in kind were so significant that the relation is no longer true.
  • the cases for which the condition var.4.2.3.2< var.4.2–(var.4.2.1+var.4.2.2) is not fulfilled, are accepted due to fact that the monthly gross earnings exclude the occasional bonuses, net profit and payments in kind. The compulsory social contribution and taxes paid by the employer on behalf of the employee are calculated to all gross amounts paid to the employee in month October (including occasional bonuses, net profit and payments in kind). For these cases the plausibility check is not relevant because the amounts paid for irregular bonuses and payments in kind were so significant that the relation is no longer true.
6.3.3. Non response error

The treatment of non-response is performed only for the first sampling phase (i.e. to the primary sampling unit level which is the enterprise) and is regarding to the survey status of enterprises and its response. The non-response type used to the collection data phase is:

 

Non-response type

Type of response used during the data collection (response code) Type of response used in the non-response adjustment procdedure Percentage (%)
Response (1) Response 85,89
Refusal (2) Non-response 6,57
Unidentified (3) Non-response 2,20
Out of scope units (4) Model assumption 1,67
Units unable to be contacted (non-contacted) (5) Non-response 0,08
Dormant unit (6) Response 2,36
Ceased unit (7) Non-response 0,28
Other unit responded (8) Response 0,80
Other events (9) Response 0,15
Grand Total - 100

 

The enterprises that reported 9 employees or less were considered out of scope units. To perform the adjustments of out of scope units by weighting procedure a model assumption was used. These assumptions are made for each stratum (to first sampling phase level) and are:

  • The out of scope units’ rate among the respondents is the same as among the non-respondents.
  • The number of out of scope enterprises in the frame is the same as the number of in scope units but not included in the sampling frame.
  • The mean value of any variable of interest is the same in the accessible part of the target population as in the inaccessible part.

 

 

The non-response rates broken down by economic activity (NACE Rev.2 division and section level) and by size classes are presented in the attached document Non-response rates.

The estimation procedure is performed in two phases, corresponding to the two sampling phases:

1) To the first sampling phase (i.e. to the primary sampling unit level which is the enterprise)

The estimation procedure involves the multiplying of the value for each sampled business (yi) by a combination of weights, one being outlier weight (wih), one resulting from the sample design (aih) and one being the non-response adjustment (nrih). An outlier weight is computed as a Windsor weight. The normal score used to set the outlier units is computed taking into account the stratification used in sample design corresponding to the first sampling phase. The adjustment of the non-response is performed by the inverse of response probability and taking into account the stratification used in the sampling design. The overall non-response rate is about 11%.

So, for each response primary unit the final weigh is

 

 

where “i” is the primary sampling unit index and “h” the stratum index.

 

2) To the second sampling phase (i.e. to the secondary sampling unit level which is the employee)

The final weight of the employee is given by multiplying the inverse of selection probability of the employee (bj), computed separately by gender (men and women), with the enterprise final weight (weightih).

So,

 

where j is the employee index.

6.3.4. Processing error

The SES questionnaire was structured in two parts:

Part A – information related to the enterprise (and where applicable, to the local units) and Part B – information relating to each employee in the sample. The variables in Part B were grouped into three chapters:

B1 – demo-economic characteristics of the employees,

B2 – the working time and the gross amounts corresponding to month October 2010,

B3 – the working time and the gross amounts corresponding to whole year 2010.

 

Detailed explanatory notes were annexed, containing: the scheme needed for the selection of the sample of employees, the definitions of the variables, the classifications of occupations (ISCO08 - 4 digit level) and the classification of educational level (ISCED - 1 digit level).

The SES is the only Romanian survey collecting the information at employee level. Generally, the respondents were guided by the statisticians from the territorial statistical offices and in some cases, even assisted by them in how to fill in the questionnaires.

Data collection was made by post or e-mail. Electronic questionnaire, designed in Microsoft Excel were also provided by INS to the respondent units, by request. But, the majority of the respondents (80%) preferred to answer by post, using paper questionnaires.

The next step was data entry and validation, for which an IT application was used to find all errors and non-correlations, occurred during data collection and data entry. The IT solution for Romanian SES was accomplished using Visual Fox and divided into two components:

  • IT solution at local level – territorial statistical offices;
  • IT solution at central level – INS headquarters (Bucharest).

 

The IT solution at local level allowed the data entry and validation at each county level (42 counties in total – NUTS3 level). The IT solution at central level contained the IT programs for:

  • integrity checking (identification data of the selected units and of the respondent units were checked – unique code of the respondent unit, fiscal code, address, NACE activity, ownership type, etc.);
  • printing the code of errors occurred and the non-correlation of the variables within same chapter or between chapters;
  • solving the errors;
  • comparisons with other surveys for the common respondent units and indicators (“Monthly wages and salaries survey”, “Wages and salaries for month October”, “Job vacancy survey”, “Labour cost survey”);
  • tabulation of non-weighted data;
  • adjustment and weighting;
  • tabulation of the results (weighted data) as Excel pivot tables;
  • automatic codification of the national variables into the standard format.

 

After validation, data were analysed and corrected where necessary. In order to provide more accurate and reliable data comparisons among variables and/or with other data sources were made.

Individual hourly, monthly and annually earnings were compared by occupations, levels of education, age and length of service within the selected employees of the same enterprise. No more than ±30% difference was accepted. In cases above or below limits, the respondent units were contacted and asked for explanations.

Basic salaries were compared with the minimum wage guaranteed by the national legislation in force. The basic salaries which were below the minimum wage were not accepted for the employees working full-time or the corresponding proportion from the minimum wage for the employees working part-time.

Monthly and annually earnings were correlated for each employee. An estimation of the annual earnings was made, taking into account the period worked during the year. This estimation was compared with the reported annual data.

The gross monthly earnings could differ from a month to another due to different financial and working conditions (i.e. break off work for technical or economic reasons, cancellation or new orders, plant breakdowns or raw materials shortage, financial difficulties or technical reasons etc.), which implies annual earnings much different than the one earned in the representative month (October) multiplied by the number of months actually worked.

The average monthly earnings aggregated by economic activities and by ownership type and financial control of the enterprises were compared with the same indicator from other two surveys – Labour costs survey 2010, Monthly wages and salaries survey (for month October 2010). For differences more than ±30% data were analysed starting from the employee level and corrected upon case.

The average monthly earnings were calculated taking into account the working program of the employees (full-time/part-time). The average annual earnings were calculated taking into account the working program of the employees (full-time/part-time) and the period actually worked during the year.

The distribution of employees by major groups of occupation was compared, for the common respondent units, with the same distribution from the Job vacancy suvey for 1st quarter 2011 (when the new ISCO-08 was implemented).

In the explanatory notes provided to the respondents there were references for all collected variables.

Some problems were caused by the manner of sample selection of the employees by the respondent units. The problems occurred not for the sample size, but for the rule of respecting as much as possible the distribution of the employees of the sample (by sex, occupation groups and working program), as the distribution of the total number of employees of the respondent unit (by sex, occupation groups and working program).

About 200 logical tests and correlations were performed for data checking.

Logical tests were focussed on key variables such as: sex, date of birth, occupation, management/supervisory position, education level, type of contract, number of hours paid, monthly gross amounts paid, individual contributions, annual gross amounts paid, number of annual days of absence (holidays, sick leave, special events, vocational training).

 

The correlations were focussed on:

  • different indicators from the same chapter (e.g. occupation – level of education, year of birth – level of education or length of service, gross amounts paid for overtime – number of overtime hours, etc.);
  • similar indicators by different reported periods (ex. gross amounts paid monthly and annually, bonuses paid monthly and annually, etc.);
  • common indicators from other surveys in the domain (total number of employees at the end of the month, the distribution of employees by occupation groups, etc.).

 Also, the checks focused on:

  • the plausibility between contractual hours, number of hours in a standard working month and the number of hours actually paid,
  • plausibility between the number of overtime hours and the payments for overtime and also the number of weeks to which the gross earnings relate, for employees starting in 2010.

 

Same tests were conducted at local level (territorial statistical offices) as well as at central level (INS). The largest part (about 75%) of the errors found was solved at local level. The figures were corrected after re-contacting the corresponding respondents.

The questionnaire design, the detailed explanatory notes, the annexes and the IT solutions developed had as result complete and of good quality data. Items of partial non-response were sent back to the respondent units for filling in the whole information.

6.3.4.1. Imputation - rate

No imputations applied.

6.3.5. Model assumption error

In Romania fiscal year fully corresponds to calendar year. No adjustment of this kind was necessary to be made.

Romanian Structure of Earnings Statistics covered all enterprises irrespective of the economic activity performed and having 10 employees and over. According to Eurostat arrangements for implementing the Council Regulation no.530/1999 and the Commission Regulation no. 1738/2005, Romania provided data for:

  1. Table A (local unit table) - data refer to enterprises with 10 or more employees (micro data file);
  2. Table B (employee table) - data refer to all surveyed (micro data file).

No combinations between survey data and register data have been undertaken. All data are obtained from the survey.

7.2. Punctuality

The data collection period for SES 2010 was lasted 3.5 months:

  • 2 months for enterprises to fill in the questionnaires and to send them to the territorial statistical offices (February – March 2011);
  • 1.5 months for the territorial statistical offices to perform data entry, data checking and to send data files to central level (April - mid-May 2011).

Thus, the deadline for receiving the files from territorial statistical offices was 16th May 2011.

Since not all enterprises respected the deadline requested, a high proportion of questionnaires were received with delay by the territorial statistical offices. Furthermore, due to the recalls necessary for additional information and corrections of the variables filled in by the enterprises, delays occurred in sending the data files to INS.

Only the information on the delays encountered in receiving the data files from the territorial statistical offices to INS is available. Below are presented information on the proportion of data files sent from the territorial statistical offices and the dates when INS received them:

  • 16 – 20 May: 76.2%
  • 21 - 31 May: 16.7%
  • 1 – 15 June: 7.1%

Thus, for the first transmission a delay of 30 days was registered between the scheduled and actual data files transmission.

Also, due to several data corrections and delayed respondent units, the files from the territorial statistical offices were remanded several times. The last transmission registered was on 24.01.2012.

Even so, no delays were registered into the data transmission to Eurostat or data dissemination at national level.

The transmission to Eurostat of the micro data files was in accordance with the legal requirements, as Gesmes files, via eDAMIS, on the 13th of June 2012 (the deadline stipulated by the Council Regulation no. 530/1999 was 30 June 2012). Also, some explanatory notes were transmitted in order to justify the plausibility checks that failed for certain records.

8. Coherence and comparability Top
8.1. Comparability - geographical

Comparability between national and European concepts on:

Definition of statistical units - There is no deviation from European concepts:

  • The unit of selection was the enterprise defined according to the communitaire rules for enterprises statististics as: ,,the smallest combination of legal units that is an organisational unit producing goods or services, which benefits from a certain degree of autonomy in decision-making, especially for the allocation of its current resources. An enterprise carries out one or more activities at one or more locations. An enterprise may be a sole legal unit”.
  • The sampled entreprises provided data for their employees belonging to different local units.

 

Populations - There is no deviation from European concepts:

  • The Romanian Business Register was designed and implemented based on the administrative files (REGIS, which is the Fiscal Register, updated annually) and statistical sources in addition (Trade Register, Balance Sheet files, VAT files, feedback from other surveys, used as consultation data sources for improving the quality of the register data).
  • According to the Council Regulations, REGIS contains the following types of statistical units: legal unit, enterprise, and local unit. All the enterprises having the main activity in the section A to S of NACE Rev.2, whatever their size (number of employees or turnover) are covered.
  • The Romanian Business Register contains all enterprises, authorities and organisations as well as their local units in Romania that carry out any economic activity irrespective of their size or if they belong to the private or public sector. There are covered the following institutional sectors:
    • Non-financial corporate and quasi-corporate enterprises
    • Central and local administration
    • Social security institutions and private non-profit institutions serving households

In respect to the budgetary institutions and public administration REGIS is the most complete register in Romania, based on Official Journal and the collaboration with many administration institutions.

 

Reference times - There is no deviation from European concepts:

  • The statistics on the structure of earnings are produced for the reference month October and for calendar year 2010, with a four-yearly periodicity.

 

Classifications - There is no deviation from European concepts:

  • The national classification of economic activities is covered by CAEN Rev.2 fully harmonized with NACE Rev.2.;
  • The national classification of occupations is covered by COR-2008 harmonized with ISCO-08;
  • The size classes of enterprises correspond to the size classes described in the Council Regulation no. 530/1999 concerning structural statistics on earnings and labour costs;
  • NUTS1 level corresponds to macro-region level.

 

Definitions of variables - There is no deviations from European concepts:

  • The definitions of SES 2010 variables were developed and adopted in accordance with European standards (Commission Regulation (EC) no 1738/2005 amending Regulation (EC) No 1916/2000 as regards the definition and transmission of information on the structure of earnings), but also taking into account the national features.
8.1.1. Asymmetry for mirror flow statistics - coefficient

[Not requested]

8.2. Comparability - over time

The Romanian SES was carried out for the third time (with 2002, 2006 and 2010 as reference years). No significant changes in definitions, coverage or classifications used since the previous survey. The improvements made in comparison with year 2006 refer only to more detailed methodological notes accompanying the survey questionnaire

The tables in the attached document Comparability over time are an illustrating example on data series continuity over the years. Due to strong inflation registered in Romania the last table shows the trends of power of purchasing expressed as the ratio of nominal earnings index divided by consumer prices index (CPI).



Annexes:

8.2.1. Length of comparable time series

[Not requested]

8.3. Coherence - cross domain

Coherence with National Accounts

The comparison between the gross annual earnings in the reference year, expressed per employee, shows some differences between Structure of Earnings Survey and National Account (NA), mainly due to the different coverage of the two data sources. In SES, enterprises with less than 10 employees are excluded, while NA contains information also, for small enterprises and hidden economy.

Main data sources for the National Accounts, by NACE Rev 2 sections are:

  • Accounting statements of financial and non-financial units,
  • Accounting statements of non-profit institutions serving households,
  • Execution of state budget,
  • Structural Business Survey ,
  • Labour Cost Survey,
  • Household Budget Survey,
  • Labour Force Survey (for employment data only),
  • Declaration on global income of self-employed persons and family associations,
  • Balance of payments.

 

 

For better data comparability:
- Sections A and O of NACE Rev.2 were excluded from SES.

Compared with SES, for section K, the NA include persons with other kind of contracts (i.e. insurance agents, field agents), that are not paid from the salary founds. Also, sections N and R include in NA data on small enterprises and hidden economy. Section S include in NA accounting and financial data (i.e. wages and salaries) on trade unions, political parties and other kinds of non-profit institutions serving households etc.

The NA data used to obtain gross annual earnings in 2010 are provisional data and might be modified in the final version.
