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_MI21, 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.
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 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.
