US Furniture Producer Price Index Methodology
BLS/FRED PCU337337 source coverage, NAICS 337 producer-price indexing, Furnilytics 2021 rebasing, and comparison with EU and China PPI pages.
Indicator scope
The US furniture producer price index measures monthly producer-price movement for furniture and related product manufacturing. It is a manufacturing price-pressure indicator and should not be read as a retail furniture price index or a measure of household furniture spending.
PCU337337Source and extraction
Furnilytics uses FRED observations for series PCU337337, which represents the producer price
index for furniture and related product manufacturing. The underlying statistical source is the US Bureau
of Labor Statistics producer price program.
Observations from January 2015 onward are retained for the public indicator. Values are sorted by month and
assigned the Furnilytics geography code US.
Rebasing
The source series is reindexed to make it comparable with the Furnilytics producer-price page convention. Furnilytics calculates the average source value across calendar year 2021 and divides each monthly source value by that average, multiplied by 100. The resulting published index has 2021 average = 100.
Calculated fields
The published page adds year-over-year fields by comparing each monthly index value with the same month one year earlier. The latest six-month year-over-year average is used as a short-term price-pressure summary so a single monthly value does not dominate the page interpretation.
How this differs from EU and China PPI pages
The US page uses a BLS producer price series accessed through FRED and mapped to NAICS 337. The EU pages
use Eurostat STS_INPP_M for NACE C31 with Eurostat's 2021-base index. The China page is
reconstructed from NBS year-over-year and month-on-month producer-price relatives before rebasing.
Because the US source classification is NAICS-based and includes furniture and related product manufacturing, exact level comparisons with NACE C31 or China source definitions should be made carefully. The strongest cross-source use case is trend direction and price-pressure timing.
Interpretation limits
The US producer price index is a factory-gate price indicator. It does not capture retail margins, sales taxes, freight after the producer stage, discounting, or consumer channel mix. Source values can also be revised by the statistical provider.
