In September 2025, the production index in the ‘Construction’ section increased by 1.4% compared to the previous month. The data are preliminary and seasonally adjusted.
The calendar-adjusted data showed a rise of 9.7% in the construction production compared to the same month of 2024.
Monthly changes
In September 2025, compared to the previous month, an increase was seen in the civil engineering - by 2.0%, in the production of specialized construction activities - by 1.3%, and in the production of building construction - by 1.2%.
Annual changes
In September 2025, compared to the same month of 2024, a rise of the production was registered in the specialized construction activities - by 11.4%, in the civil engineering - by 9.7%, and in the construction of buildings - by 8.2%.
Methodological notes
The monthly indices show the short-term changes in the construction production between two comparable periods. This information can be used to analyse the current state of construction activity in the country, as well as a short-term forecast for its future development.
The indices are calculated on the basis of information on hours worked in construction. The data are collected with a monthly sample survey that includes construction enterprises, whose production exceeds 75% of the total production in construction. Construction Production Indices are calculated on the base 2021 = 100. Since 2024, the data has been provided according to the requirements of Regulation (EU) 2019/2152 and Regulation (EU) 2020/1197.
Seasonal adjustment is a statistical method that eliminates the seasonal component of time series.
Calendar adjustment is an adjustment for variations in the monthly data, caused by calendar effects, the different number of calendar and working days in the months, national holidays and outliers (for example, the presence of more non-working days in September could contribute to the decline in the production in some activities).
Since September 2024, all dynamic rows have been recalculated based on 2021 as base year and are published in IS Infostat.
