A tally (also see tally sticks) is an unofficial private observation of an election count carried out under Proportional Representation using the Single Transferable Vote. Tallymen, appointed by political candidates and parties, observe the opening of ballot boxes and watch as the individual ballot papers are counted. Individual tallymen may be placed to observe the opening of each box and watch as separate bundles of ballot papers are sorted, stacked and counted. They record their estimation of counts by marking votes for each candidate on their 'tally sheet' as a tick (/) which are then assembled together to produce a full prediction of what the likely outcome of the result will be. Many political parties, having been rival during elections, co-operate in producing a tally.
Tally results are then released to the media before a formal account may even have begun, allowing predictions as to how some, or in most cases all, the seats in multi-member constituencies, may go hours in advance of the official count, by noting how many number 1s a candidate may get, who gets their number 2s, whether voters vote for one party or spread their first, second, third, fourth etc. preferences randomly, by party, by alphabet, by local area, or by some other criteria. In the Republic of Ireland, a national prediction of an election outcome may be made on RTÉ by lunchtime on count day, before a single seat has officially been filled.
Tally results are used after the elections by political parties to work out, on the basis of from which ballot box the tally came, how many votes they picked in a particular area, or even a particular street. The planned introduction in the Republic of Ireland of electronic voting for the 2004 local elections was expected to lead to the demise of the tally system, however, widespread criticism of the electronic voting programme has meant that a hand-count remains in operation in Ireland . Tally predictions and long complex counts have given election outcomes on television and radio much of their appeal, making election results coverage, which may last from 15 hours to days, depending on the closeness of an election, producing a form of spectator sport watched by vast viewerships.
For a sort of variation on writing numbers in the unary numeral system, see Tally mark.
Tallyman, UK usage
In poorer parts of England (including the north and London's East End), the tallyman was the hire purchase collector, who visited each week to collect the payments for goods purchased on the never never, or hire purchase. These people still had such employ up until the 1960s. Another possible definition is a person who called to literally do a head count, presumably on behalf of either the town council or the house owners. This is rumoured to have occurred in Liverpool, in the years after the First World War.
