Data standards

Every number needs a trail.

PolisMetric publishes coverage, source classes, update status and limitations. Production construction remains proprietary.

Historical span1865–2024

Country and historical coverage is shown directly. Missing observations remain missing rather than being presented as observed values.

Published measures are governed by source-quality and evidence-status controls so changes in evidence quality can be reviewed consistently.

PolisMetric maintains a controlled research dataset so current public outputs are produced from the approved research version.

Protected implementation: production construction remains proprietary.
