3.1.1. Organisation

The national  PPP exercise is conducted by National Institute of Statistics . 

At central level, the organisation of National Institute of Statistics is based on directorates with attributions in providing economic and social statistics.  At territorial level, NIS has 42 statistical territorial offices with attributions in collecting data for statistical surveys.

The coordination of the national PPP exercise is done by the PPP department, Directorate of Price Statistics, under the co-ordination of General Directorate of Economic Statistics, as June 2025.

(see organisational chart).

Box 1.1: National Institute of Statistics Romania- Organisational Chart  

 

 

The PPP unit is responsible for:

  • Carrying out  the pre-survey work for each consumer price survey by visiting outlets, extracting information from the Internet, contacting  the dealers/producers/service providers by e-mail, phone or fax; 
  • Filling in the answers and the proposals for the consumer goods survey lists using the ILMT tool.
  • Participating in the all country  meetings, starting with 1999, in order to draw up the product list in consultation with the other  participating countries; 
  • Translating the final product list for each consumer price survey in order to be distributed to the price collectors;
  • Collecting price data in the capital city for the consumer price surveys;
  • Filling in the price data  provided by  the price collectors for the consumer price surveys, in the Data Entry Tool (DET) ;
  • Drawing up the reports for consumer price surveys;
  • Validating the price data during the validation procedure coordinated by the Group leader, using the Validation Tool;
  • Carrying out the survey on the compensation of employees in order to supply the data for the “Salary questionnaire”;
  • Collecting data in order to supply information for “Hotels questionnaire”
  • Coordinating the submission of the data for the following standard questionnaires: GDP expenditure weights, VAT, actual and imputed rentals and consumer price indices;
  • Validating and approving the results for all PPP questionnaires;
  • Ensuring the interface between Eurostat and national experts in charge with carrying out the pre-survey and price collection for “Equipment goods” and “Construction”;
  • Carrying out the Estate Agencies Rent survey in the capital city;
  • Coordinating the submission of the data for the “Health questionnaire”;
  • Calculation of SAFs for consumer goods surveys”;
  • Updating the PPP inventory according to the Eurostat guidelines.

In the process of data submission and validation of standard questionnaires, the following directorates of NIS are involved:

  • Directorate of National Accounts -supplying data for GDP expenditure weights questionnaire, VAT, tips and rates of employers’ contribution for salaries ;
  • Directorate of Price Statistics - supplying data for consumer price indices questionnaire and  information concerning specific issues  for the PPP consumer price surveys;
  • Directorate of Short Term Economic Indicators Statistics- supplying data on quality and quantity indicators of the dwelling stock for rent questionnaire, as well on tourism statistics for “Hotels questionnaire”;
  • Directorate of Social Statistics – supplying the data concerningHealth Survey  from  2011 onwards.

Between  1999-2016, the organisation of the consumer price surveys  had a specific feature in Romania due to the fact that  the price collections were carried out  not only in the capital city (Bucharest), but also in other seven cities.: (Brasov; Constanta; Craiova; Cluj; Iasi; Ploiesti and Timisoara). There were involved one survey coordinator for each territorial statistical offices, two price collectors in each city mentioned above and 6 price collectors for the capital city. The above mentioned cities represent the most populated and economically developed localities at the level of each development region (NUTS level 2). The decision to carry out the consumer price surveys not only in capital city was made having in view the methodological requirement to provide national average prices and due to the fact that Spatial Adjustment Factors were not available for Romania. Therefore, at territorial level, the staff involved in carrying out the price collection for each consumer price survey consisted of: one survey coordinator at the level of the 8 territorial statistical offices (including capital city);

Considering that Spatial Adjustment Factors were calculated and became available starting with the year 2017, from then onwards the price collection will be carried out only in the capital city (Bucharest). Therefore,6 experts from the Bucharest Regional Statistical Office are involved in carrying out the price collection for capital district and they are coordinated by one regional coordinator.

 Resources

 The stages of data collection, processing and  validation  for the PPP exercise require trained staff, both at central level and territorial level.Human resources involved in the national PPP exercise are the following :

  • at  central level
    • one full-time national PPP co-ordinator,who are in charge with the co-ordination of the work for PPP exercise at the national level;
    • 4 experts from the PPP department (including the PPP national coordinator), who are full-time involved in carrying out the PPP surveys; 
    • 1 Director and 1 Deputy Director from the Price Statistics Direction who are part-time involved in the PPP exercise being responsible for approving all the PPP results;

7. Confidentiality Top
7.1. Confidentiality - policy

National Institute of Statistics-Romania provide to Eurostat all the basic data necessary for calculation of the PPPs, both individual price observations and national expenditure data at the basic heading level.

According to the agreement between participating countries to the comparison exercise and Eurostat all individual prices are strictly confidential because they are collected for the specific purpose of calculating PPPs and not for publication.

Concerning the access to data on national expenditures and PPPs at the basic heading level for all participating countries to the PPP exercise, Eurostat and OECD grant the access for academic and researchers on two conditions, namely: there is a clear scientific purpose for which the data are used and researchers sign a written agreement of confidentiality.

In order to undertake global comparison it is necessary to link the results of Eurostat- OECD comparison with the results of the other regional comparisons, so that data on national expenditures and PPPs at the basic heading level of the participating countries to ECP are provided by Eurostat and OECD for the International Comparison Programme (ICP).

7.2. Confidentiality - data treatment

At national level, the individual price observations collected for the PPP consumer price surveys are confidential. Also, the average prices calculated for the PPP consumer price surveys and national expenditure data at the basic heading level are confidential.

The national users have access to the PPP results according to the level of  disaggregation established by Eurostat in Eurobase.

National Institute of Statistics has a very strict protection policy according to the Statistical Law no. 226/2009, concerning the organisation and the functioning of the official statistic in Romania.

The fundamental principle of statistical confidentiality stipulated in
Statistical Law no. 226/2009 means the protection of confidential data related to single statistical units, that are obtained directly for statistical purposes or indirectly from administrative or other sources and implies the prohibition of their use for other purposes than the statistical ones and their unlawful disclosure.

Under the provision of this law, NIS cannot publish, or otherwise make available to one individual or organization, statistics that could enable the identification of data for any individual person or entity. (chapter X, Article 36 of the statistical law).

The subcontractors which are involved in data collection for the “Equipment Goods” and “Construction” surveys have to ensure the confidentiality of the survey data during and after the price collection, according to the contract signed with Romanian NSI.
