This page provides the entire Eora MRIO for download. For each year there are ten sheets: one values matrix and one standard deviations matrix for each of the five price margins (Basic prices, trade markup, transport markup, taxes markup, and subsidies markup). A guide to the Eora MRIO structure is here: Eora2Structure.xlsx.

Metadata

The MRIO is provided broken into its constituent blocks:

• The intermediate demand transactions matrix T (note: in some IO literature this is called the flows matrix and denoted as Z)
• The primary inputs block v (note: in some IO literature this is called the Value Added block)
• The final demand block y
• The gross output vector x
• The satellite accounts QT and Qy document non-monetary inputs to production (pollutant releases, resource use, social impact, etc.) and final demand satellite accounts document such inputs and releases associated with final demand users (principally, households and government)

For details on the classifications used in the above please use the metadata which can be downloaded from the metadata page.

Data Versions

We periodically release updated datasets. It is recommended that you store these data in a folder named with the current version number: 20260515T121739.

Download files for Full Eora

Full Eora provides an MRIO where each country uses either a default comon classiification, or where available, its own national sectoral classification. This best preserves the integrity of published national statistics, at the expense of making inter-country comparisons more complex.

Demo Data

Here you can download demo data for the Full Eora (year 1991).

Scripted and programmatic downloads

The files can be downloaded programmatically using the following URL template:

https://www.eora.org/r2/Eoras/versions/[VERSION]/datasets/[FC]_eora/[YEAR]/matrices/Eora2_[FC]_[BLOCK]_[YEAR]_[MARGIN].txt.zip?et=[TOKEN]

and the labels at:
https://www.eora.org/r2/Eoras/versions/[VERSION]/datasets/[FC]_eora/[YEAR]/indices.zip?et=[TOKEN]

where:

• [VERSION] is the version number (currently 20260515T121739),
• [FC] is either the Full or Common Classification model (full or common),
• [BLOCK] is the block code (T, x, v, y, QT, Qy),
• [YEAR] is the year (the latest year available is 2024),
• [MARGIN] is the margin code, one of: basic_price, taxes_on_products, duties, subsidies_on_products, trade_margin, transport_and_other_margins
• The files for QT and Qy have no margin code, so the filename ends with [YEAR].txt.zip. Also note that the value added block v is only defined in the basic price margin. Requesting v on other margins will result in a File Not Found message.
• [TOKEN] is your user token. Your token will be visible when you log in.
