The data matching results will help you determine whether the property as a whole is matched or unmatched and you must use this information to help you to allocate that property to the appropriate canvass route.1
Matched properties - A property is determined to be a matched property where there is a match result for every elector within a property, through national and/or local data. A property can also be determined to be a matched property where you have carried out local data matching and have confirmed the status of the property as empty.
Unmatched properties - A property is determined to be an unmatched property where you are unable to match some or all of the electors within a household through national and/or local data matching.
Both national and local data matching results may be relevant in determining the appropriate canvass route. For example, you may:
Accept a match from either local or national data matching
Override a match result from national data matching where you are satisfied that local data matching information is more accurate - this may be because you believe your local data source to contain more up-to-date information
Override a result from local data matching if you believe the national data match has provided a more accurate result
What action can I take where an individual is unmatched?
You cannot disregard the results where both national and local data shows at least one elector in the property as not matched.
However, you could consider using other local data sources that you trust to be accurate to try to match the unmatched elector before allocating that property.
If you are able to match an unmatched individual using other local data sources, you may then be satisfied that the whole property is a match and could be canvassed via Route 1 - the matched property route.
Where you do not have additional local data to use, or are unsuccessful in matching the unmatched elector using additional local data, canvass the property via Route 2 – the unmatched property route - as you cannot be satisfied that there are no changes to be captured for that property.
