Statistics Finland changed the calculation method of transactions to correspond to the delimitation rules of the National Land Survey. The numbers of transactions published with the new calculation method grew on the level of the whole country by an average of one per cent in 2020 and 2021. In 2022, the numbers were around five per cent higher, in 2023 over 10 per cent higher and in 2024 nearly 20 per cent higher than with the previous calculation method.
The growth in the numbers of transactions also affected the price development of old one-dwelling houses, so the index series for the base year 2020 were corrected completely. The index series of old base years were chained with the corrected changes starting from the statistical reference year 2022.
On average, the nominal price indices of old one-dwelling houses became revised yearly on the level of the whole country as follows:
- In 2020, the change is under +0.1 percentage points.
- In 2021, the change is -0.7 percentage points.
- In 2022, the change is -0.7 percentage points.
- In 2023, the change is -4.5 percentage points.
- In 2024, the change is -0.4 percentage points.
The revisions are largest during the statistical reference year 2023. Examined by size of municipality, nominal price indices for 2023 were, on average, revised as follows:
- In municipalities with over 100,000 inhabitants the change is -2.1 percentage points.
- In municipalities with 60,000 to 100,000 inhabitants the change is -3.9 percentage points.
- In municipalities with 20,000 to 59,999 inhabitants the change is -3.5 percentage points.
- In municipalities with under 20,000 inhabitants the change is -6.8 percentage points.
The average prices per square metre of old one-dwelling houses changed yearly by nearly one per cent in the whole country in the statistical reference years 2020 to 2023. In 2024, prices per square metre were revised upwards by around 3.5 per cent.
