<P> But, there were two significant exceptions . The City of London had never expanded its boundaries and, with many residential dwellings being replaced by businesses, and the destruction of The Blitz, after the Second World War the financial district had barely five thousand residents altogether . The system of plural voting was retained for electing the City of London Corporation, with some modifications . </P> <P> When Northern Ireland was established in 1921, it adopted the same political system then in place for the Westminster Parliament and British local government . But, the Parliament of Northern Ireland did not follow Westminster in changes to the franchise up to 1950 . As a result, into the 1960s, plural voting was still allowed for both Parliament and local government . This meant that in local council elections only ratepayers and their spouses, whether renting or owning the property, could vote while company directors had an extra vote by virtue of their company's status . University representation continued at Stormont to 1969, while it was abolished for Westminster in 1948 . Historians and political scholars have debated the extent to which the franchise for local government contributed to Unionist electoral success in controlling councils in Nationalist - majority areas . </P> <P> Based on a number of inequities, the Northern 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 elections (national elections followed the same eligibility rules as the rest of the UK). The slogan "one man, one vote" became a rallying cry for this campaign . The Parliament of Northern Ireland voted to update the voting rules, which were implemented for the Northern Ireland general election, 1969 . </P> <P> The United States Constitution requires a decennial census for the purpose of assuring fair apportionment . The census has generally been conducted without incident with the exception of the 1920 Census which was effectively skipped pending resolution by the Reapportionment Act of 1929 . Congressional seats have been reapportioned based on population changes between states . State legislatures initially established election of congressional representatives from districts, often based on traditional counties or parishes which preceded founding of the new government . The question arose as to whether the state legislatures were required to ensure that congressional districts were roughly equal in population and to draw new districts to accommodate demographic changes . </P>
