Terminology

The names for electoral districts vary across countries and, occasionally, for the office being elected. The term ''constituency'' is commonly used to refer to an electoral district, especially in British English, but it can also refer to the body of eligible voters or all the residents of the represented area or only those who voted for a certain candidate. The terms ''(election) precinct'' and ''election district'' are more common in American English. In Australia and New Zealand, electoral districts are called ''electorates'', however elsewhere the term ''electorate'' generally refers specifically to the body of voters. In

, which can be literally translated to English as "electoral area" though the official English translation for the term is "constituency". The term "Nirvācan Kṣetra" is used while referring to an electoral district in general irrespective of the legislature. When referring to a particular legislative constituency, it is simply referred to as "Kṣetra" along with the name of the legislature, in Hindi (e.g. 'Lok Sabha Kshetra' for a

District magnitude

''District magnitude'' is a term invented by the American political scientist Douglas W. Rae in his 1967 dissertation ''The Political Consequences of Electoral Laws''. It refers to the number of seats assigned to each district, and thus the easiness to be elected, as the threshold ''de facto'' decreases in proportion. The concept of magnitude explains Duverger's observation that

Minorities

Magnitude is a major factor in the inclusion of minorities. Plurality (and other elections with lower district magnitudes) are known to limit the representation of minorities.

Apportionment and redistricting

''Apportionment'' is the process of allocating a number of representatives to different regions, such as states or provinces. Apportionment changes are often accompanied by ''redistricting'', the redrawing of electoral district boundaries to accommodate the new number of representatives. This redrawing is necessary under single-member district systems, as each new representative requires their own district. Multi-member systems, however, vary depending on other rules. Ireland, for example, redraws its electoral districts after every

Gerrymandering

''Gerrymandering'' is the manipulation of electoral district boundaries for political gain. By creating a few "forfeit" districts where opposing candidates win overwhelmingly, gerrymandering politicians can manufacture more, but narrower, wins for themselves and their party. Gerrymandering relies on the wasted-vote effect, effectively concentrating wasted votes among opponents while minimizing wasted votes among supporters. Consequently, gerrymandering is typically done under voting systems using single-member districts, which have more wasted votes. While much more difficult, gerrymandering can also be done under proportional-voting systems when districts elect very few seats. By making three-member districts in regions where a particular group has a slight majority, for instance, gerrymandering politicians can obtain 2/3 of that district's seats. Similarly, by making four-member districts in regions where the same group has slightly less than a majority, gerrymandering politicians can still secure exactly half of the seats. However, any possible gerrymandering that theoretically could occur would be much less effective because minority groups can still elect at least one representative if they make up a significant percentage of the population (e.g. 20-25%), compared to single-member districts where 40-49% of the voters can be essentially shut out from any representation.


Swing seats and safe seats

Sometimes, particularly under non-proportional winner-take-all voting systems, electoral districts can be prone to

Constituency work

Elected representatives may spend much of the time serving the needs or demands of individual ''constituents'', meaning either voters or residents of their district. This is more common in assemblies with many single-member or small districts than those with fewer, larger districts. In a looser sense, corporations and other such organizations can be referred to as constituents, if they have a significant presence in an area. Many assemblies allow free postage (through
