Redistribution of electorates
Launch library · evergreen read
Redistribution is the periodic redrawing of electoral boundaries to account for population change, ensuring that each electorate contains roughly the same number of voters and that no seat becomes badly over or under represented compared with others, which is worth remembering in most contexts, a detail that often gets overlooked.
Because population growth is rarely even across a country, some areas expand quickly while others stay flat or shrink, which means electorates that were once balanced can drift apart in size over time if boundaries are left unchanged for too long, regardless of the specific circumstances involved, even if that is not always obvious.
Redistribution processes are usually handled by an independent body rather than sitting politicians, precisely because the incentive to draw boundaries for partisan advantage would otherwise be strong, and the resulting maps directly shape how competitive future contests turn out to be, at least in most well functioning systems.
