It might be tempting (and indeed, some people do) to look at the results of STV and FPTP and decide that generally there is closer match between national support and seats under STV, and conclude STV is a 'form' of PR . But that's a bit like saying there is a closer match between national support and seats under FPTP than, say, a one-party state, and conclude that FPTP is a form of PR.
STV is not a form of PR because there is no mechanism within it to deliver proportionality between share of support and seats. It's a preferential system and, as such, brings the first, second and third choices of voters into consideration. No consideration of proportionality is made within the counting process.
The Electoral Reform Society lists many reasons for backing STV at Electoral Reform Society - Single Transferable Vote No way do they claim that STV delivers proportionality or is a form of PR. I certainly would not support STV if it did or was.[/QUOT
STV delivers a proportional result within the constituency it is therefore a 'form' of proportional representation. It is one 'form' of many proportional systems, one being the party list system which it seems is the only system that you consider to be PR. Nobody could argue that FPTP is a form of PR because it has a very different intended outcome, it is a form of majority 'winner takes all' system.
The electoral reform society most certainly DO consider STV as a form of PR http://www.politics.co.uk/opinion-formers/Electoral-Reform-Society/campaigns-$470346$7.htm It was in fact originally formed in 1884 as the proportional representation society and adopted STV in 1885 as their preferential form of PR voting system.
