EU Furniture Producer Price Index Methodology
Eurostat STS_INPP_M source coverage, NACE C31 producer-price indexing, 2021-base values, year-over-year enrichment, and comparability limits.
Indicator scope
The EU furniture producer price index pages measure monthly factory-gate producer price movement for furniture manufacturing. They are manufacturing-side price-pressure indicators, not retail-price, consumer-price, margin, or market-size measures.
The indicators are intended for country-level market context. They are useful alongside production turnover, retail market size, trade, and material-cost indicators because they help separate producer-price pressure from demand-side movement.
STS_INPP_M, with national statistical extensions where a direct public country row is maintained separatelyI21, index 2021 = 100Source and extraction
Furnilytics uses Eurostat table STS_INPP_M, the monthly short-term producer price index table.
The extraction filters to NACE Rev. 2 C31 for manufacture of furniture, unit I21
for index 2021 = 100, and non-seasonally adjusted observations.
Country rows are retained for individual market pages. Eurostat country and aggregate codes are normalized into the Furnilytics geography fields used by the indicator library.
Standard PPI rather than domestic PPI
The published EU pages use the standard Eurostat producer price index for furniture manufacturing. This differs from a domestic-only producer price series, which would restrict coverage to prices for domestic output. The standard series is used because it gives a broader manufacturing price signal for the furniture industry and is more suitable for cross-country market context in the Furnilytics hub pages.
Because price-index definitions can differ by source family, EU values should be compared most directly with other EU pages built from the same Eurostat table and filter set.
Calculated fields
The source index value is published as the main observation. Furnilytics adds year-over-year fields for indicator pages by comparing each monthly value with the same month one year earlier. The page also highlights a latest six-month year-over-year average to reduce the weight of a single monthly observation.
Country-specific extensions
Most European country pages use the directly reported Eurostat C31 furniture manufacturing producer price
index for that country. Switzerland, Norway, and Croatia are handled through the standard Eurostat
STS_INPP_M furniture manufacturing series in the current Furnilytics PPI table.
Estonia
Estonia is added through a national-source backend extension before being merged into the European PPI table. The extension uses the Statistics Estonia monthly producer price index for furniture manufacturing.
Latvia
Latvia is added through a national-source backend extension before being merged into the European PPI table. The extension uses the Central Statistical Bureau of Latvia monthly producer price index for furniture manufacturing.
Serbia
Serbia is added through a national-source backend extension using the Statistical Office of the Republic of Serbia dissemination database. Furnilytics filters the monthly producer price index table to KD 2010 activity 31, manufacture of furniture. The Serbian source provides month-on-month index movement, so Furnilytics chains those monthly changes into a continuous level series and rebases the result to 2021 = 100 before merging it into the European furniture PPI table.
United Kingdom
The United Kingdom is added from ONS producer price index series G942,
PPI index output total - C31 furniture. Furnilytics rebases the ONS 2015 = 100 source series to
a 2021 = 100 average before merging it into industry/indexes/eu_ppi_furniture.
European aggregate
The Europe row is calculated bottom-up from the shared monthly furniture production table. Furnilytics
aggregates nominal and real furniture production values across the included European country rows, derives
an implied producer-price ratio from nominal divided by real production, and normalizes that series to a
2021 = 100 average before publishing it in industry/indexes/eu_ppi_furniture.
Keeping Estonia, Latvia, Serbia, and the United Kingdom as separate extension refreshes means a national-source failure does not block the standard Eurostat PPI refresh for other countries.
Slovakia
Slovakia remains a transparent peer-based extension where a directly confirmed Slovakia C31 furniture producer price series is not currently used in the Furnilytics public indicator set. The proxy combines available C31 furniture producer price indexes from comparable European supplier countries and weights them by Slovakia's recent furniture imports from those partners.
How this differs from US and China PPI pages
The EU pages use Eurostat as the common source, with a harmonized European statistical classification framework and a source-provided 2021-base index. The US page uses a BLS producer price series accessed via FRED and is reindexed by Furnilytics to a 2021 average. The China page uses official NBS producer-price relatives and reconstructs a monthly level index before rebasing.
These source differences mean that cross-region comparisons are most reliable for direction, timing, and broad price-pressure context. Exact index levels should be interpreted within each source system.
Interpretation limits
A producer price index measures prices received by producers at the manufacturing stage. It does not include retail margins, VAT, consumer discounts, logistics charges after the factory gate, or changes in retail channel mix. It also does not measure production volume or market size.
Eurostat and national statistical observations may be revised, and some countries report later than others. Furnilytics refreshes the dataset when the source updates and preserves the source index structure rather than smoothing or seasonally adjusting the published values.
