The index of production in construction is calculated to characterise the changes in construction output during the reference period, in comparison with the base period.


According to Statistical Classification of Economic Activities (NACE Rev. 2) the activity Construction (Section F) includes construction of buildings (Division 41), civil engineering (Division 42) and specialised construction activities (Division 43).
It includes new construction, repairs, reconstruction and renovation, assembly and erection of prefabricated constructions on site and construction of temporary buildings.

Characterises changes in construction output during the reference period, in comparison with the base period.

Additional information

In some cases, due to specifics of electronic data processing technologies and rounding adjustments, slight discrepancies may occur between the totals and sums of components.

Data collection

Survey method and data source

Construction output data are acquired with sample survey. The data are compiled based on the CSB quarterly questionnaire on construction (1-construction).

Target population

The data are collected from economically active enterprises the main or secondary activity of which in compliance with the NACE Rev. 2 is Construction (Section F, classes 41.10–43.99), which in construction employ 30 or more persons, the turnover of which in the previous year amounted to 4.5 million euros or more. Other commercial companies engaged in construction are surveyed based on simple random sampling.

Statistical processing

Calculation methods

After processing of the source data and development of summaries, the data are analysed by comparing them with those on the previous period and corresponding period of the previous year (at constant prices), and increase/ decrease analysis is carried out as well.

Logical analysis of non-adjusted construction output, building, civil engineering and specialised construction activities volume index takes place by evaluating increase/ decrease in indicators, as compared to the previous period and corresponding period of the previous year.

Seasonally adjusted construction output, building, civil engineering  and specialised construction activities structure volume indices are analysed graphically.

Construction volume is re-calculated into constant prices with the help of construction cost index. For more complete analysis of data, the volume indices of production in construction of buildings, civil engineering and specialised construction activities are adjusted.

Calculation of Volume index of production in construction is based on the chain index method; within the framework of it the average quarterly volume of production (at constant prices) previous year is used as a calculation basis and the value added of construction enterprises two years ago by NACE chapters is used as weights.Volume index of production in construction is calculated by recalculating production output indicator at constant prices with the help of construction cost index. Weights are changed every year, thus changes in the structure of construction are taken into account.

Calendar and seasonal adjustment

A time series is a sequence of observations collected at regular time intervals, for example, a monthly time series. It characterises indicator changes or development thereof.  Seasonality and calendar effects are present in a large number of economic time series.

Seasonality or seasonal fluctuations of time series mean those movements, which recur with similar intensity in the same season each year. For example, each year Christmas shopping time can be observed in time series reflecting retail sales statistics. Change of seasons, social habits and influence of institutional factors are among the main causes of seasonality.

The calendar effects cover influence of calendar on time series. It is impact left by differing number of working days (or Mondays, Tuesdays and other days of the week) in months on changes of indicator. For example, number of working days differing among the months may affect goods produced time series.

When the time series are influenced by seasonality or calendar effects, it may be difficult to get clear understanding on indicator changes over the time.  Seasonal adjustment is made to eliminate seasonal fluctuations and calendar effects in time series.

As a result seasonally adjusted time series, from which seasonality and calendar effects have been removed, are produced. It means that seasonally adjusted time series provide an estimate for what is “new” in the series, for example turning points in trends, business cycle or irregular component.  Moreover seasonal adjustment results in calendar adjusted time series, in which calendar effects or varying number of working days in months has been eliminated. Specifics of seasonally adjusted statistics allows improving data comparability over time:

  • Seasonally adjusted time series do not contain seasonal fluctuations and calendar effects, thus it is possible to compare, for example, data on the current month with the previous month's data.
  • Calendar adjusted time series are not influenced by calendar effects and are used to compare, for example, statistics on current month with the data on corresponding month of the previous year.

The seasonal adjustment is made taking into account seasonal adjustment guidelines developed by the European Statistical System.
