Data Limitations & Caveats
Nationality, not ethnicity. All datasets use nationality (country of citizenship). Nationality is not a proxy for ethnicity or race.
"Returns" includes many outcomes. Enforced removals, voluntary departures, port refusals. Not all are forced removals.
No individual-level linking. Prison population and deportation data cannot be linked at the individual level — all cross-references are aggregate correlations.
Correlation, not causation. A high prison population relative to deportations does not imply those individuals should or could be deported.
Prison population is a snapshot. It measures who is in prison at a point in time (stock), not annual flow. Direct comparison with annual returns is approximate.
Age-sex adjustment matters. When adjusted for the younger, more male demographic profile of foreign nationals, non-UK nationals are slightly underrepresented in prison overall (Migration Observatory, Sept 2025).
Population denominators are uncertain. For small nationalities (Afghan, Eritrean), ONS estimates may understate the actual UK population by 2–3x, which inflates per-capita rates.
