Data Catalog
Every BEA input-output table processed by Leontief, in three machine-readable formats. Data are derived from the U.S. Bureau of Economic Analysis (BEA) Annual I-O Accounts, Summary Level (71-sector).
Data provenance
- Source
- U.S. Bureau of Economic Analysis (BEA) Annual Input-Output Accounts, Summary level, retrieved via the BEA API. Public domain (a work of the U.S. federal government).
- Attribution
- Matrices A, A_square and the Leontief inverse L = (I − A)⁻¹, plus the derived multiplier and linkage series, are computed by Leontief (an Arcanum Research project) from the BEA Use and Supply tables using standard input-output methodology. See Methodology.
- Units & coverage
- Dimensionless technical coefficients and multipliers (the underlying BEA accounts are in current-dollar producer values). 71 sectors (BEA Summary), 1997–2024 (28 annual vintages).
- Downloads
- Every matrix and series is downloadable as CSV, XLSX and Parquet (no JSON). Bulk: all.zip.
- Refresh cadence
- Annual, on BEA release. The BEA publishes new annual I-O accounts roughly once a year (typically autumn); Leontief is refreshed by re-running the Anu data pipeline against the BEA API when a new vintage appears. Method: manual pipeline run.

Data inventory
Every BEA dataset loaded and hosted by this site. Coverage: BEA Summary level, 71 sectors, 1997–2024 (28 annual vintages). Snapshot built 2026-08-03 from the BEA API; this is the retrieval date of record for every table below.
| Dataset | Type | Vintages | Years | Dims (per year) | Source of record |
|---|---|---|---|---|---|
| Use | raw | 28 | 1997–2024 | 79 × 92 | BEA Use table (Use_IxI_Summary_YYYY.json) — commodity × industry intermediate use + final demand |
| Supply | raw | 28 | 1997–2024 | 74 × 83 | BEA Supply/Make table (Supply_IxI_Summary_YYYY.json) — commodity × industry production |
| A | derived | 28 | 1997–2024 | 70 × 71 | Direct-requirements coefficients (non-square 70×71), derived from the Use table |
| A_square | derived | 28 | 1997–2024 | 71 × 71 | Direct-requirements coefficients, squared to the row∩col intersection |
| L | raw | 28 | 1997–2024 | 71 × 71 | BEA Total Requirements / Leontief inverse (Total_Requirements_IxI_Summary_YYYY.json) |
| VA | derived | 28 | 1997–2024 | 4 × 71 | Value-added rows (V-codes) extracted from the BEA accounts |
| FD | derived | 28 | 1997–2024 | 70 × 19 | Final-demand columns (F-codes) extracted from the Use table |
“raw” = a BEA-published table loaded as-is; “derived” = computed by this
site from the raw tables using the documented
methodology. Per-year provenance for each table is
recorded in site_data/site_manifest.json.

Seven matrix types per year. Use — absorption matrix (industries × commodities); Supply — make matrix (industries × commodities); A — direct-requirements coefficient matrix; A_square — square (industry × industry) version of A; L — Leontief inverse (I − A)⁻¹; VA — value-added rows; FD — final demand columns.
Derived Series
Time-series tables computed from the annual matrices (e.g. sector multipliers over 1997–2024, backward/forward linkage indices).
