Construction output

Construction output data are used to estimate changes in the volume of this sector.

Construction output consists of the value of own-account construction works completed by the construction enterprises.

Surveyed units - kind of activity units.

Responding units - enterprises.

The target population covers all economically active enterprises the main or secondary activity of which in compliance with the NACE Rev. 2 is construction (Section F, classes 41.20–43.99).

• Council Regulation (EC) No 1165/98 of 19 May 1998 concerning short-term statistics

Statistics database

EU data on Eurostat website Section: Construction, building and civil engineering.

Data on the construction output index are comparable since 2000. Construction output at current prices by industry is available from 2015, but by type of construction from 2018.

N/A

The data are compiled based on the CSB quarterly questionnaire on construction (1-construction).

Framework source: Statistical Business Register (SUR)

Type of sample: single - stage sample

Sampling coordination: independent sampling

Stratification variables: target population, industry, size class by number of employees

Allocation: optimal proportional

Sampling: A stratified simple random sample

Target population: In 2022, economically active statistical units whose main activity is NACE Section F, excluding industry 4110 and excluding statistical units whose ISK starts with S13.

The sample includes all enterprises with at least 20 employees and NACE Rev. 2. F 4213 with at least 5 employees. Units with fewer employees are surveyed at random using stratified simple random sampling. Statistical units with less than 5 employees (except NACE Rev. 2 F 4322, 4332, 4334, 4339 - with less than 20 employees and NACE Rev. 2 F 4333, 4399 with less than 7 employees) are valued, using administrative data (volume of VAT transactions).

The number of units in each part of the population varies. It is adjusted to include new economically active enterprises (according to the above criteria) in the set of surveyed statistical units, specifying the economic activities of enterprises, receiving additional or clarified information from respondents, as well as more up-to-date data from administrative data sources.

Data on construction output are collected using Form 1-Construction "Report on self-construction by enterprises". Most data is submitted in the form of an e-report, other forms of submission (mail, e-mail, telephone) are less common.

When the form or automatic validation controls change, training for data collectors (statisticians) is provided, as well as instructions are prepared for both respondents and statisticians.

Respondents receive notifications and reminders about the need to submit a report if the submission deadline is approaching. If the respondents do not submit the report in time, they will be contacted by statisticians. Each report (respondent) not submitted on time is coded with an appropriate non-response code with an explanation attached to it.

When connecting to the e-reporting system and selecting the appropriate report, the information about the applicant is filled in automatically and only the information needs to be checked and corrected (in case of changes).

After the data submitted by enterprises are processed, the amount of works at actual prices is aggregated in corresponding classes, groups and divisions of NACE Rev. 2 Section F and in building types (residential and non-residential buildings) of Classification of Types of Construction.
