CHAPTER VI ORIGINS AND INTERMARRIAGE IN THE REGISTRATION AREA IN CANADA INTRODUCTION The study of the varying extents to which intermarriage has occurred between the different stocks included in the population of Canada is as complex as it is important. The jrst type of difficulty arises because of the limited data which are available. The census does not publish a separate classification of the married population by origins; consequently a direct approach to the study is impossible. An alternaiive method would be to analyze the, marriages in the census year; but even were the records of origins included in the provincial official notices of marriage, it is doubtful whether the intermingling of different stocks, as indicated by marriages in a given year, would be representative of the tota amount of intermarriage which had taken place. The tendency would be to over-emphasize it, due to the fact that as the length of residence of the immigrant population in Canada increases, the extent of intermarriage also increases. . It would obviously be wrong to assume that the rate applying in 1921, which marriage data for that year might supply, would be applicable to people who were in this country ten or twenty years ago and con- tracted their marriages in those years. Further, on account of the varying inflow of immigrant peoples, the marriage data of any given year would be unreliable as a guide to the total amount of intermarriage. This is especially true of the decade 1911-1921 with its great fluctuations in immigration. However, even if these objections did not exist to the use of marriages as an index of assimilation, such procedure is impossible. since informa- sion as to origin is not available in the marriage returns. The alternative source of information, on which of necessity this study has been based, is the origin of the parents of children born in the Registration Area of Canada in the year 1921, as given in the “First Apnnal Report on Vital Statisties” of the Dominion Bureau of Statistics. The first limitation imposed in using these data is the fact that as the province of Quebec compiled and published its own vital statistics at that time, the reports of thst province are not comparable with the figures for the other provinces as compiled and edited by the Dominion Bureau of Statistics. Since 1926, the vital statistics for Quebec are on the same basis as those of the other provinces under the Bureau, but the present study for the census year 1921 can embrace only that part of Canada which at that time was included in the Registration Area. Another difficulty is the variations in the amount of detail in which origin classifications are given in the various tables of the Census and Vital Statistical Reports, and the absence of certain analyses important for a comparative study of this nature. The limitation of space in the census and the exnense involved in compilation and publication account for this. Offsetting these drawbacks the use of the origin of fathers and mothers of children born in 1921 has many advantages. First, it is not open to the objections applying to the use of marriage data. The parents of the children born in 1921 are much more representative of the married population with tespect to origin than are the young people who were married in that single year. Further, such data are not so sensitive to the inflow of immigrant population. And finally, there were over three times as many births as marriages in the year 1921. The actual number of births reported in the Registration Area in the year of the census was 168,979. For some 22,000 of those, the origins of the parents are not given. Over 12.000 of that number occur in Alberta, making the data for that province less ‘16
