Construction Output YoY

Construction Output YoY gauges euro-area building activity monthly. Eurostat publishes it, the statistical office of the European Union. Its official name is Production in construction. The index tracks monthly changes in price-adjusted construction output across NACE Rev.2 Section F. The euro-area monthly series starts in January 1990.

The index reads 2021 = 100 as its base year. It sits in short-term business statistics among the Principal European Economic Indicators. Law runs from Council Regulation No 1165/98 of 19 May 1998 to Regulation (EU) 2019/2152. It measures volume, not nominal values or prices. It does not track building permits, house prices, or PMI-style business sentiment.

The indicator arrives monthly in the Euro indicators news release, on dates announced in advance in the Luxembourg-time release calendar. Publication lands about 7 weeks after the reference month, at 11:00 Luxembourg time. Large and medium sized countries file monthly within a month and 15 days of the reference month, while small ones report quarterly.

Each release prints euro-area, EU, and Member State figures with month-on-month and year-on-year tables by component. Figures flow from monthly dataset sts_copr_m. It also links the STS database section, a construction-production explainer, the 2021 country weights file, the dashboard, and the calendar. Earlier months are revised every round on incomplete first coverage and re-estimated seasonal adjustment. The publisher sets no expansion or contraction threshold. Trends come from the seasonally and calendar adjusted monthly change and the calendar adjusted annual change.

Three NACE divisions drive the reading, weighted by 2021 country weights in European totals.

• Construction of buildings, F41: residential and non-residential building work.
• Civil engineering, F42: railways, roads, bridges, airport runways, dams, and similar works.
• Specialised construction activities, F43: completion, installation, and specialist trades worth over half of EU construction.

The publisher prints no fixed component shares. No European total appears below 60% coverage; missing country months are estimated. National seasonally adjusted series combine into a weighted average.

In the April 18, 2024 release for February 2024, the seasonally adjusted total rose 1.8% in the euro area. Buildings added 3.5%, civil engineering 4.1%, and specialised work 1.7%. Yet the calendar adjusted annual total fell 0.4%, as buildings dropped 2.5% while civil engineering jumped 4.9% and specialised work edged down 0.1%. The same release revised January 2024 from 0.5% to 0.2% on the month and from 0.8% to a 0.3% annual fall. A strong monthly bounce can coexist with an annual fall while civil works outrun buildings.

1. Deflation: national money variables become volume through output-price deflators, never input-cost deflators. Labour inputs gain a productivity tweak, sub-contracting payments drop out to block double counting, and stocks adjust turnover-based reads.
2. Laspeyres index: series take Laspeyres form as value-added volume indices on base year 2021 = 100, held since March 2024 after 2015 = 100. The 2021 base is exceptional, since bases are normally years ending in zero or five and move every five years.
3. Calendar and seasonal adjustment: working-day adjustment comes first, countries seasonally adjust their data, and Eurostat covers the rest with TRAMO-SEATS in JDemetra+.
4. Indirect aggregation: European totals average national seasonally adjusted series by country weights. It needs 60% weight coverage, with missing months estimated.
5. Monthly and annual rates: the monthly change divides the index for a month by the index for the previous month, minus 1, times 100. It uses seasonally and calendar adjusted data. The annual change divides by the same month of the previous year on calendar adjusted data.

Invented numbers show the exact steps: a seasonally adjusted index of 102.2 in January and 103.1 in February gives 0.9% monthly growth. A calendar adjusted 102.6 for last February against 103.1 for this February gives 0.5% annual growth.
