In this paper I intend to do little more than sketch in very broad outline some of the main features of the electoral anatomy of the province of Ontario as revealed by the official provincial election returns. Since I have relied solely on the actual voting record, which is, of course, tabulated by constituencies, my method is ecological and, unlike survey methods, provides only rough and indirect measures of the social and economic factors related to voting behaviour. My findings are entirely descriptive and do not go much beyond what is accessible to any alert newspaper reader who may have followed Ontario politics over the past two decades.
The chief methodological problem confronting ecological analysts of voting behaviour is how to equate electoral units with the administrative units by which population characteristics are tabulated in the census. In Ontario the smallest units for which official election statistics are given are polling subdivisions, but these fail to correspond to any units for which data on population characteristics are available. However, data on voting by townships can be derived from the election returns, and the census tabulates population characteristics by townships. I have made some determination of the voting habits of ethnic groups from data on townships, but have not set out these findings in detail in the present paper, which does not analyse units smaller than constituencies, and is thus confined to a very broad scrutiny of differential voting patterns.
