"One man, one vote"[a] or "one vote, one value" is a slogan used to advocate for the principle of equal representation in voting. Thisslogan is used by advocates ofdemocracy andpolitical equality, especially with regard toelectoral reforms likeuniversal suffrage,direct elections, andproportional representation.
The violation of equal representation on a seat per vote basis in various electoral systems can be measured with theLoosemore–Hanby index, theGallagher index, and other measures of disproportionality.[1][2][3]
The phrase surged in English-language usage around 1880,[4] thanks in part to Britishtrade unionistGeorge Howell, who used the phrase "one man, one vote" in political pamphlets.[5] During the mid-to-late 20th-century period ofdecolonisation and the struggles for national sovereignty, this phrase became widely used indeveloping countries where majority populations sought to gain political power in proportion to their numbers.[citation needed] The slogan was notably used by theanti-apartheid movement during the 1980s, which sought to end white minority rule inSouth Africa.[6][7][8]
In the United States, the "one person, one vote" principle was invoked in a series of cases by theWarren Court in the 1960s during the height of related civil rights activities.[9][10][11][12][b]
By the second half of the 20th century, many states had neglected to redistrict for decades, because their legislatures were dominated by rural interests. But during the 20th century, population had increased in urban, industrialized areas. In addition to applying theEqual Protection Clause of the constitution, theU.S. Supreme Court majority opinion (5–4) led byChief JusticeEarl Warren inReynolds v. Sims (1964) ruled that state legislatures, unlike theU.S. Congress, needed to have representation in both houses that was based on districts containing roughly equal populations, with redistricting as needed after the decennial censuses.[14][15] Some states had established an upper house based on an equal number of representatives to be elected from each county, modelled after the US Senate. Because of changes following industrialization and urbanization, most population growth had been in cities, and the bicameral state legislatures gave undue political power to rural counties. In the 1964Wesberry v. Sanders decision, the U.S. Supreme Court declared that equality of voting—one person, one vote—means that "the weight and worth of the citizens' votes as nearly as is practicable must be the same".[16] They ruled that states must draw federal congressional districts containing roughly equal represented populations.
This phrase was traditionally used in the context of demands forsuffrage reform. Historically the emphasis within theHouse of Commons was on representingareas:counties, boroughs and, later on,universities. The entitlement to vote for theMembers of Parliament representing the constituencies varied widely, with different qualifications over time, such as owning property of a certain value, holding an apprenticeship, qualifying for paying the local-government rates, or holding a degree from the university in question. Those who qualified for the vote in more than one constituency were entitled to vote in each constituency, while many adults did not qualify for the vote at all.Plural voting was also present in local government, whereby the owners of business property qualified for votes in the relevantwards.[citation needed]
Reformers argued that Members of Parliament and other elected officials should represent citizens equally, and that each voter should be entitled to exercise the vote once in an election. SuccessiveReform Acts by 1950 had both extended the franchise eventually to almost all adult citizens (barringconvicts,lunatics and members of theHouse of Lords), and also reduced and finally eliminated plural voting for Westminster elections. Plural voting for local-government elections outside the City of London was not abolished until theRepresentation of the People Act 1969.[17][18]
WhenNorthern Ireland was established in 1921, it adopted the same political system then in place for the Westminster Parliament and British local government. But theParliament of Northern Ireland did not follow Westminster in changes to thefranchise from 1945. As a result, into the 1960s, plural voting was still allowed not only for local government (as it was for local government in Great Britain), but also for the Parliament of Northern Ireland. This meant that in local council elections (as in Great Britain), ratepayers and their spouses, whether renting or owning the property, could vote, and company directors had an extra vote by virtue of their company's status. However, unlike the situation in Great Britain, non-ratepayers did not have a vote in local government elections. The franchise for elections to the Parliament of Northern Ireland had been extended in 1928 to all adult citizens who were not disqualified, at the same time as the franchise for elections to Westminster. But, university representation and the business vote continued for elections to the House of Commons of Northern Ireland until 1969. They were abolished in 1948 for elections to the UK House of Commons (including Westminster seats in Northern Ireland). Historians and political scholars have debated the extent to which the franchise for local government contributed tounionist electoral success in controlling councils innationalist-majority areas.[19]
Based on a number of inequities, theNorthern Ireland Civil Rights Association was founded in 1967. It had five primary demands, and added the demand that each citizen in Northern Ireland be afforded the same number of votes for local government elections (as stated above, this was not yet the case anywhere in the United Kingdom). The slogan "one man, one vote" became a rallying cry for this campaign.[citation needed] The Parliament of Northern Ireland voted to update the voting rules for elections to the Northern Ireland House of Commons, which were implemented for the1969 Northern Ireland general election, and for local government elections, which was done by theElectoral Law Act (Northern Ireland) 1969, passed on 25 November 1969.[citation needed]
TheUnited States Constitution requires adecennial census for the purpose of assuring fair apportionment of seats in theUnited States House of Representatives among the states, based on their population. Reapportionment has generally been conducted without incident with the exception of the reapportionment that should have followed the1920 census, which was effectively skipped pending resolution by theReapportionment Act of 1929. State legislatures, however, initially established election of congressional representatives fromdistricts that were often based on traditional counties or parishes that had preceded founding of the new government. The question then arose as to whether the legislatures were required to ensure that House districts were roughly equal in population and to draw new districts to accommodate demographic changes.[12][10]
Some U.S. states redrew their House districts every ten years to reflect changes in population patterns; many did not. Some never redrew them, except when it was mandated by reapportionment of Congress and a resulting change in the number of seats to which that state was entitled in the House of Representatives. In many states, both North and South, this inaction resulted in a skewing of influence for voters in some districts over those in others, generally with a bias toward rural districts. For example, if the 2nd congressional district eventually had a population of 1.5 million, but the 3rd had only 500,000, then, in effect – since each district elected the same number of representatives – a voter in the 3rd district had three times the voting power of a 2nd-district voter.
Alabama's state legislature resisted redistricting from 1910 to 1972 (when forced by federal court order). As a result, rural residents retained a wildly disproportionate amount of power in a time when other areas of the state became urbanized and industrialized, attracting greater populations. Such urban areas were under-represented in the state legislature and underserved; their residents had difficulty getting needed funding for infrastructure and services. Such areas paid far more in taxes to the state than they received in benefits in relation to the population.[15]
TheConstitution incorporates the result of theGreat Compromise, which established representation for the U.S. Senate. Each state was equally represented in the Senate with two representatives, without regard to population. TheFounding Fathers considered this principle of such importance[citation needed] that they included a clause in the Constitution to prohibit any state from being deprived of equal representation in the Senate without its permission; seeArticle V of the United States Constitution. For this reason, "one person, one vote" has never been implemented in the U.S. Senate, in terms of representation by states.
When states established their legislatures, they often adopted a bicameral model based on colonial governments or the federal government. Many copied the Senate principle, establishing an upper house based on geography – for instance, a state senate with one representative drawn from each county. By the 20th century, this often resulted in state senators having widely varying amounts of political power, with ones from rural areas having votes equal in power to those of senators representing much greater urban populations.
Activism in theCivil Rights Movement to restore the ability of African Americans in the South to register and vote highlighted other voting inequities across the country. In 1964–1965, theCivil Rights Act of 1964 andVoting Rights Act of 1965 were passed, in part to enforce the constitutional voting rights ofAfrican Americans.[20] Numerous court challenges were raised, including in Alabama, to correct the decades in which state legislative districts had not been redefined or reapportioned, resulting in lack of representation for many residents.
InColegrove v. Green, 328 U.S. 549 (1946) the United States Supreme Court held in a 4–3 plurality decision thatArticle I, Section 4 left to the legislature of each state the authority to establish the time, place, and manner of holding elections for representatives.
However, inBaker v. Carr, 369 U.S. 186 (1962) the United States Supreme Court under Chief JusticeEarl Warren overturned the previous decision inColegrove holding that malapportionment claims under theEqual Protection Clause of theFourteenth Amendment were not exempt from judicial review underArticle IV, Section 4, as the equal protection issue in this case was separate from any political questions.[12][16] The "one person, one vote" doctrine, which requires electoral districts to be apportioned according to population, thus making each district roughly equal in population, was further affirmed by theWarren Court in the landmark cases that followedBaker, includingGray v. Sanders, 372 U.S. 368 (1963), which concerned thecounty unit system in Georgia;Reynolds v. Sims, 377 U.S. 533 (1964) which concernedstate legislature districts;Wesberry v. Sanders, 376 U.S. 1 (1964), which concernedU.S. congressional districts; andAvery v. Midland County, 390 U.S. 474 (1968) which concernedlocal government districts.[16][21][22]
The Warren Court's decision was upheld inBoard of Estimate of City of New York v. Morris, 489 U.S. 688 (1989).[23]Evenwel v. Abbott, 578 U.S. 2016, said states may use total population in drawing districts.[22]
InAustralia,one vote, one value is a democratic principle, applied in electoral laws governingredistributions ofelectoral divisions of the House of Representatives. The principle calls for all electoral divisions to have the same number of enrolled voters (not residents or population), within a specified percentage of variance. The electoral laws of the federalHouse of Representatives, and of the state and territory parliaments, follow the principle, with a few exceptions. The principle does not apply to theSenate because, under theAustralian constitution, each state is entitled to the same number of senators, irrespective of the population of the state.
Currently, for the House of Representatives, the number of enrolled voters in each division in a state or territory can vary by up to 10% from the average quota for the state or territory, and the number of voters can vary by up to 3.5% from the average projected enrolment three-and-a-half years into the future.[44] The allowable quota variation of the number of electors in each division was reduced from 20% to 10% by theCommonwealth Electoral Act (No. 2) 1973, passed at thejoint sitting of Parliament in 1974.[45] The change was instigated by theWhitlam Labor government.
However, for various reasons, such as the constitutional requirement that Tasmania must have at least five lower house members, larger seats likeCowper (New South Wales) comprise almost double the electors of smaller seats likeSolomon in theNorthern Territory.
Historically, all states (other than Tasmania) have had some form ofmalapportionment, but electoral reform in recent decades has resulted in electoral legislation and policy frameworks based on the "one vote, one value" principle. However, in the Western Australian and Queensland Legislative Assemblies, seats covering areas greater than 100,000 square kilometres (38,600 sq mi) may have fewer electors than the general tolerance would otherwise allow.[46][47]
The following chart documents the years that the upper and lower houses of each Australian state parliament replaced malapportionment with the 'one vote, one value' principle.
| State | NSW | Qld | SA | Tas | Vic | WA |
|---|---|---|---|---|---|---|
| Upper House | 1978[48] | Abolished in 1922[49] | 1973[50] | 1995[51] | 1982[52] | 2021[53] |
| Lower House | 1979[54] | 1991[55] | 1975[56] | 1906[57] | 1982[52] | 2005[58] |
The Whitlam Labor government proposed to amend the Constitution in areferendum in 1974 to require the use of population to determine the size of electorates rather than alternative methods of distributing seats, such as geographical size. The bill was not passed by theSenate and instead the referendum was put to voters using the deadlock provision inSection 128.[59] The referendum was not carried, obtaining a majority in just one State and achieving 47.20% support, an overall minority of 407,398 votes.[60]
In 1988, the Hawke Labor government submitted areferendum proposal to enshrine the principle in theAustralian Constitution.[61] The referendum question came about due to the widespreadmalapportionment andgerrymandering which was endemic duringJoh Bjelke-Petersen's term as the Queensland Premier. The proposal was opposed by both theLiberal Party of Australia and theNational Party of Australia. The referendum proposal was not carried, obtaining a majority in no States and achieving just 37.6% support, an overall minority of 2,335,741.[60]
