How these numbers are measured
Scope: decided hearing-level cases whose per-allegation profile records this issue, matched to the same issue value the search filters use, so a count here and a filtered search always agree. A case raising several issues counts under each one. The mitigating conditions and the credited circumstances below were extracted for a subset of the record, so both are counts of cases rather than rates. Pages exist only for issues with at least 25 decided cases, and † marks any split built on fewer than 20.
Reading the statistics
- Granted = access granted or continued; Denied = denied or revoked.
- Grant rate = granted ÷ (granted + denied).
- † marks figures based on fewer than 20 cases, too few to be reliable.
- Hovering any rate shows its statistical range (a 95% confidence interval).
- Figures are descriptive counts over decided, public DOHA ISCR decisions, never predictions or assessments of any pending case.
