Methodology

How validated findings are sourced, dated, counted, and limited.

Measure

The connected annual charts report validated policy findings in this release and should not be read as an exhaustive count or statistical estimate of all policy activity. Lines connect annual release counts for readability; they do not claim continuous measurement between years or establish causal comparisons between countries. One finding represents the lowest independently operative substantive national migration-policy effect. The 2026 period ends September 13.

Evidence and dates

Each public finding passed automated exact-claim checks against saved official evidence. The operative date is the date the effect took operation, not merely an announcement or publication date. Material target groups, conditions, exceptions, transitions, quantities, fees, thresholds, quotas, and expiries are retained when they form part of the validated claim.

Counting

Separable legal effects are split and inseparable effects are merged. A shared date or source alone does not make two records duplicates. Known unresolved duplicate and counting-unit groups are withheld from public totals. Unchanged renewals and routine continuations do not create a new finding.

Limits

Automated source validation is not independent human legal review and is not legal advice. The published counts describe this release's validated findings, not a complete census or a statistical estimate of all activity. Unresolved material is preserved only in internal review materials.
