NOTES ON METHODOLOGY
Sources and methods of data collection
Data on construction presented in this publication is collected through reporting method by using the Monthly Report on Construction (GRAĐ-21/M form).
Coverage and comparability
The Monthly Report on construction is collected from legal entities and parts thereof employing 20 or more persons classified in the Register of Business Entities to section F Construction according to the NKD 2007. About 900 reporting units are included in the average annual dynamics.
Data refer to all construction works (new constructions and reconstructions, maintenance and repair works on existing constructions) done on the territory of the Republic of Croatia.
The coverage of construction activities is harmonised with the NKD 2007. section F Construction (NN, No. 58/07). Constructions and works are classified according to the Classifications of Types of Constructions − KVG (NN, No. 11/98). Both classifications are harmonised with appropriate classifications prescribed by Eurostat (NACE rev. 2; Classifications of Types of Constructions − CC, final version).
Index method
Total volume index of construction is based on the number of hours worked on sites, according to the Methodology of short-Term Business Statistics, Eurostat 2002.
The seasonal adjustment was done by applying the "Demetra" programme interface, version 2.0 (SP1) – Eurostat, using the X-12-ARIMA method (version 0.2.8 installed) on the monthly index series (Æ 2005 = 100), beginning with the index for January 1998. A trend cycle is a series of seasonally adjusted indices with the exclusion of the influence of irregular components. The prolongation of the basic index series by adding of new monthly data may cause subsequent change of seasonally adjusted series and trend cycle for several previous months, due to characteristics of the applied method of seasonal adjustment.
More detailed methodology notes of these inquiries are published in NN, No. 11/98.
