Information on the observation
Purpose – The short term statistics shows the trend of economic development of a country in quarterly periods, by which the police makers can develop a short term plan for the further development of the country. The development of the main indicators such as; industrial production, turnover, number of employees and wages in time series are described by this publication
Coverage- based on main economic activity the main activities covered in the STS survey for producer goods is as following:
- Industry - composed by Mining and quarrying and Manufacturing industry (05-33)
- Electricity, Gas, and Steam (35)
- Water supply; Sewerage; Waste management and Remediation activities (36 - 39)
- Construction (41. 42. 43)
Model - The enterprises are selected from the Statistical Register of Enterprises. The enterprises with 1-9 employees are surveyed by sample survey, whereas the enterprises with 10 and more employees are surveyed exhaustively.
Data collection - Administrative data sources and data from Quarterly Survey of Short-Term Statistics with face to face interview method are used for the data collection.
Indicators – The indicators are given in Index form the quarterly changes are given in percentage whereas the annual changes are given in percentage with reference to the base year actually 2021=100. The data do not present absolute values.
Indexes – The indexes show the changes in time of a given variable or of a group of variables. The Index Volume is calculated through the Laspeyres Formula. The indices are deflated with the proper price index by activities to avoid the prices impact. Such as the Industry indicator are deflated with Producer Price Index; Construction activity with Construction Cost Index; Hotel activity with Consumer Price Index. Transport with implicit price index calculated, etc.
The annual change in percentage - it measures in percentage the change of economic indicators of the actual quarter compared with the same quarter of the previous year.
The quarterly change in percentage – it measures in percentage the change of economic indicators of the actual quarter against compared with the previous quarter of the same year.
Revision – Indexes may be revised due to several reasons: additional information, the methodological changes or re-evaluation of the used coefficients etc.

Seasonal adjustment
Seasonal adjustment of quarterly time series of producer of materials goods is done by using JDemetra+ 2.2.4 version software. The chosen model for the decomposition of time series is X-12 ARIMA, under specification X-13.
X-12 ARIMA model is totally based in moving average. In all-time series is applied the multiplicative decomposition and the direct approach. During the process of seasonal adjustment are treated even the special case occurred during the time series span, identified by software as outlier.
