Inclusion criteria

Which sources we collect, and why. This page lists the kinds of registers in our data today and the checks a source goes through before its records are published. Our formal source-selection policy is being written.

To be provided: our source-selection policy: the principles for adding a source, the public-interest test we apply, what context and level of detail a source must give, and our commitment to keeping a source once added. This needs owner wording; nothing here should be read as that policy.

Kinds of sources we hold today

Every source is an official or public register, collected from its publisher. By list type:

Kind	Examples of publishers	Records today
Sanctions and asset-freeze lists	Global Affairs Canada, US Treasury (OFAC), the European Union, the UK, the United Nations	350,348
Politically exposed persons and public office holders	Parliaments, election bodies and public-official registers	1,303,162
Debarment and exclusion lists	Procurement, health-programme and professional regulators	880,247
Regulatory and enforcement notices	Published tax warrants and insolvency proceedings	—
Company, ownership and other registries	Business and beneficial-ownership registers, used to corroborate and enrich	Not in the screening data

The full list of registers, with their publishers and record counts, is on All data sources. How we collect them is on Methodology.

Public interest

To be provided: which kinds of people and organizations we consider in scope (for example sanctioned parties, debarred parties, politically exposed persons, their relatives and associates, wanted or convicted persons), and the reasons. Our data today covers the kinds in the table above; relatives and associates are not modelled.

Justification and context

To be provided: what a source must say about why a party is listed (legal basis, programme, decision) before we add it.

Level of detail

To be provided: the minimum identifying detail we expect from a source (for example birth dates, nationality, identity numbers) and how we treat sources that give names only. The share of records with each field is shown on the data dictionary.

Licence and legality

Before a register’s records are published or offered for download, we record the publisher’s terms of use and a licence position for it. Registers that may not be redistributed stay out of the bulk files, and some are used only to check other sources. The positions are listed on Licence positions, and the terms for reusing our data are in the data licence. Recording each register’s actual licence terms, where only a default rule applies today, is data backlog item 34.

Suggest a source

If you know of an official register we should collect, use the suggest-a-source form on the contact page, or write to [email protected]. Give the register’s name, its publisher and a link to it.

Sources in progress

To be provided: whether to publish a list of sources we are working on or have been asked to add, and if so, what it shows (register, publisher, status) and how often it is updated.
