17.1. Data revision - policy | |||
Data revisions follow the Revision Policy of the NIS Romania, which represent one of the key documents of the office. The same revision policy is applied to data released nationally and transmitted to Eurostat. Calendar of standard revisions is being prepared together with the release calendar. (http://www.insse.ro/cms/en/content/revision-policy). 1. Routine revisions: The revised indices are published together with the preliminary indices for the following month. Notice is given at the time the change is introduced. 2. Major revisions: In the case of regular index rebases (as a rule every five years), the results and changes in the calculation methodology or major changes as classification notice are presented in detail in the Monthly Statistical Bulletin and on the NIS website well in advance of the change. 3. Non scheduled revisions: In case of errors correction are made without waiting for scheduled revisions. 4. The same revision policy is applied nationally and in transmissions to Eurostat. The difference between initial figures and revised figures represents about +/-1% of the initial figures for total construction cost index. Vintage database are not available. |
|||
17.2. Data revision - practice | |||
The data are preliminary when first released and are revised three months after the end of the reference month. The difference between initial figures and revised figures represents about +/-1% of the initial figures for total construction cost index. Major changes in methodology are announced in all statistical publications at the time of the change.The status of data is clearly indicated in the publications. No MAR and MR are not calculated. |
|
|||
18.1. Source data | |||
The construction cost index is derived from the data collection on labour and materials .The statistical data about labour and materials are based on statistical surveys. |
|||
18.2. Frequency of data collection | |||
Monthly |
|||
18.3. Data collection | |||
One combined questionnaire regarding value of construction works, main groups of construction materials used in construction works, number of employees, wages and salaries, investment is used. (CON TS – Short term indicators in construction in month ……., Chapter MAT Main groups of construction materials, used in month ...... and chapter NRSAL Number of employess and wages and salaries). Data are collected in principal using a web questionnaire. For the rest of the respondent units paper questionnaire or electronic format by e-mail is used. The paper questionnaires are sent to the reporting units and then collected by county statistical offices. From 2010 onwards data are collected online using the eSOP portal for statistical data collection. |
|||
18.4. Data validation | |||
The IT solution for Monthly survey on short-term statistics was developed to find out the measurement and processing errors occurred in different stages of the survey. The application was designed for on line data collection and validation. Before data transmmition to Eurostat the structure of the data file and format is checked in detail. |
|||
18.5. Data compilation | |||
The index is a Laspeyres type index with fixed base. Cost indices in construction are calculated as the weighted mean of construction materials price indices, construction equipment indices, transport expenditure and indirect expenditure as well as the gross nominal earnings index. The weights used for aggregation represent the expenditure structure in construction based on specific statistical surveys with 5 year periodicity (the last one was for the base year 2021). Cost indices in construction are calculated for total construction (CANE Rev. 2 section F), by structural elements (new construction works, capital repairs and maintenance works and current repairs) and by construction type (residential buildings, non-residential buildings and engineering construction). |
|||
18.6. Adjustment | |||
