Housing Market Activity Methodology
Indicator goal
Housing activity matters for furniture markets because changes in home purchases, mortgage availability, construction starts, and building permits often precede furnishing decisions. The goal of the indicator family is to give market analysts a consistent monthly view of whether housing conditions are becoming more or less supportive for home-related demand.
Each country series is expressed as an index with 2019 = 100. Values above 100 indicate activity above the 2019 baseline, while values below 100 indicate weaker activity than the baseline period.
Composite construction
Furnilytics combines housing-finance and construction-side signals where suitable source data is available. The standard European structure uses new housing-loan activity as the larger component and residential permits or construction activity as the smaller component. Components are first indexed to their 2019 average and then combined with fixed weights.
The index is not intended to equal the number of housing transactions. It is a market-activity proxy that blends financing conditions and residential supply momentum into a single monthly series.
Country source differences
The exact source mix differs by country because housing finance, construction and transaction datasets are not published with identical coverage or timeliness across markets.
Smoothing and provisional months
Some housing-finance series can move sharply from month to month because of refinancing waves, policy effects, reporting timing, or temporary source distortions. Where this materially improves readability and comparability, Furnilytics applies a light 3-month moving average to the mortgage input before rebasing and weighting. This is currently used for Spain, Lithuania, Italy and Poland.
When a country has quarterly residential permit data but no suitable monthly permit series, Furnilytics converts the quarterly construction signal to monthly frequency using that country's monthly new mortgage lending distribution within each quarter. Lithuania uses this approach with Eurostat quarterly residential permits and ECB pure new housing loans, so renegotiated or refinanced loans do not inflate the housing activity signal. Any months beyond the latest available quarterly permit observation are extended from mortgage month-on-month movement until the next quarterly permit release becomes available.
Poland also excludes the newest overlapping month from the public composite. This reduces the risk that a visible final-point jump is caused by provisional release timing between mortgage and permit sources rather than an established housing-market signal.
Interpretation and limitations
A rising housing market activity index usually points to improving conditions for housing-linked demand, while a falling index suggests weaker support from the residential cycle. For furniture markets, the indicator should be read alongside retail market size, consumer confidence, online search trends and country-specific housing context.
Cross-country comparisons should focus on broad direction and relative position against each country's own 2019 baseline. They should not be interpreted as a direct ranking of housing transaction volumes, mortgage balances, or construction units.
