Annual Roll Integrity Review

• The Annual Roll Integrity Review (ARIR) is one of the AEC's measures of accuracy and completeness of the electoral roll.
• Enrolments as at 30 June each year are compared with addresses in a range of external data sources.
• The results indicate divisional accuracy (the proportion of electors where external data corroborates the enrolled division) and address accuracy (the proportion of electors where external data corroborates the enrolled address).
