Peter W. WARD et Patricia C. WARD (Vancouver, Canada) A 29 THE STANDARD OF LIVING IN MONTREAL, CANADA, 1850-1900 The effects of industrialization upon the living standards of ordinary people have long been disputed. From Marx and Engels to Hobsbawm and Thompson the pessimistic view has been that the great transformation undermined condi- tions of life for virtually all early industrial workers in developing societies, Great Britain in particular. On the other hand optimists such as Macaulay, Cla- pham, and more recently Hartwell, while admitting that workers experienced low standards of living during the early industrial era, have held that economic development gradually improved the lot of most common folk (1). One reason why this disagreement has never been resolved is that the various statistical indi- ces created to describe past living standards — be they price, wage, production, consumption, or demographic series — have seldom been as reliable or as closely tied to real conditions as their compilers might have wished. The study of infant birth weights offers a new and potentially rewarding approach to the standard of living problem because of the link between the weight of a newborn child and its mother's condition during pregnancy, especially her diet. Three groups of factors collectively determine weight at birth : maternal health, pregnancy history, and the genetic or constitutional characteristics of both mother and child. Although it was not generally recognized until well into the twentieth century, nutrition is a central element in the first of these factors and has a direct bearing upon fetal growth. High calorie diets are associated with high maternal weight gain during pregnancy and high infant birth weights. Conversely, significant food deprivation is linked with lower neonatal weights. During a six month famine in western Holland in the winter of 1944-45 the mean decline in the weights of newborn infants was more than 300 grams. An average drop of over 500 grams was recorded in Leningrad during the famine seige of 1941 to 1943 (2). Numerous other factors also affect maternal health and, in turn, the weight of a woman's offpring. Smoking, high alcohol intake, and some forms of drug consumption slow fetal development. Many debilitating medical conditions occur- ring in pregnancy influence the unborn, including diabetes and heart disease. Social and economic rank, marital status, and education levels are also correla- ted with a mother's heath and thus with the weight of a child wich she bears (3). Factors associated with the history of a pregnancy, the second group of variables, also influence neonatal weights. Complications such as toxemia, uterine infection, incompatible blood types, hypertension, and congenital malformations can retard gestation. Parity and child spacing may have an effect. Those placed second, third, and fourth in the family constellation, and those born more than two years apart, are on average somewhat heavier than others. Premature and multiple births, too, are also normally associated with low weight at birth. 71
