Methodology

This page explains how EveryPolitician collects, organises, and maintains data about political office-holders.

Data sources

We collect data from several types of sources:

  • Official government websites: Parliamentary member lists, cabinet announcements, and judicial appointments
  • International databases: Global databases of world leaders and heads of state
  • Wikidata: Community-maintained structured data from the Wikimedia ecosystem

All sources are documented on our data sources page.

Types

We track several categories of political positions:

National level

  • Executive: Heads of state, heads of government, cabinet ministers, senior civil servants
  • Legislative: Members of parliament, senators, representatives
  • Judicial: Supreme court judges, constitutional court members

Subnational level

  • Regional executives: Governors, premiers, chief ministers
  • Regional legislators: State parliament members, provincial councillors
  • Local government: Mayors, city council members

Other roles

  • State enterprises: Executives of major state-owned companies
  • International bodies: Representatives to international organisations

Position status

For each position, we track whether it is currently occupied and by whom. Positions can have one of several statuses:

  • Current: The person currently holds this position
  • Past: The person previously held this position
  • Unclear: We lack precise dates to determine current status

The "unclear" status occurs when our data sources indicate someone holds or held a position, but don't provide clear start and end dates. We're working to improve date coverage over time.

Updates and accuracy

Data is updated automatically when our sources change. For Wikidata-sourced information, updates typically appear within a few days of edits being made.

If you spot an error, the best way to fix it is to contribute a correction.
