The great transformation: a long-run perspective on physical well-being in Canada.

Abstract: During the 19th century the physical stature of the Canadian-born stagnated or declined slightly in spite of a substantial increase in income. Stature varied regionally within Canada. The Quebec population was especially short; men in the Atlantic coastal region were taller than their low incomes would lead us to expect. Heights increased dramatically in the 20th Century. The pattern of long-run change is consistent with evidence of age-specific mortality and with the relationship between income and physical well-being envisaged by Preston [Preston, S., 1975. The changing relationship between mortality and the level of economic development. Popul. Stud. 29, 231-248]. The transition from stagnant or declining stature to secular increase points to a dramatic shift ca. 1900 in the evolution of the physical standard of living in Canada.

Health, height, and the household at the turn of the twentieth century

Abstract: This article examines the health and height of men born in England and Wales in the 1890s who enlisted in the army at the time of the First World War, using a sample of recruits from the army service records. These are linked to their childhood circumstances as observed in the 1901 census. Econometric results indicate that height on enlistment was positively related to socio-economic class, and negatively to the number of children in the household in 1901 and the proportion of household members who were earners, as well as to the degree of crowding. Adding the characteristics of the locality has little effect on the household-level effects. However local conditions were important; in particular the industrial character of the district, local housing conditions, and the female illiteracy rate. These are interpreted as representing the negative effect on height of the local disease environment. The results suggest that changing conditions at both household and locality levels contributed to the increase in height and health in the following decades.

Tracking people over time in 19th century Canada for longitudinal analysis

Abstract: Linking multiple databases to create longitudinal data is an important research problem with multiple applications. Longitudinal data allows analysts to perform studies that would be unfeasible otherwise. We have linked historical census databases to create longitudinal data that allow tracking people over time. These longitudinal data have already been used by social scientists and historians to investigate historical trends and to address questions about society, history and economy, and this comparative, systematic research would not be possible without the linked data. The goal of the linking is to identify the same person in multiple census collections. Data imprecision in historical census data and the lack of unique personal identifiers make this task a challenging one. In this paper we design and employ a record linkage system that incorporates a supervised learning module for classifying pairs of records as matches and non-matches. We show that our system performs large scale linkage producing high quality links and generating sufficient longitudinal data to allow meaningful social science studies. We demonstrate the impact of the longitudinal data through a study of the economic changes in 19th century Canada.

Longitudinal studies of human growth and health: a review of recent historical research: longitudinal studies of health

Abstract: This paper reviews recent literature using stature and weight as measures of human welfare with a particular interest in cliometric or historical research. We begin with an overview of anthropometric evidence of living standards and the new but fast-growing field of anthropometric history. This literature is always implicitly and often explicitly longitudinal in nature. We then discuss (i) systematic empirical research into the relationship between conditions in early life and later life health and mortality and (ii) historical evidence on the relationship between body mass, morbidity and mortality. We conclude with a discussion of the importance of historical sources and understandings to health economics and population health.

The Determinants of Mortality

Abstract: Mortality rates have fallen dramatically over time, starting in a few countries in the 18th century, and continuing to fall today. In just the past century, life expectancy has increased by over 30 years. At the same time, mortality rates remain much higher in poor countries, with a difference in life expectancy between rich and poor countries of also about 30 years. This difference persists despite the remarkable progress in health improvement in the last half century, at least until the HIV/AIDS pandemic. In both the time-series and the cross-section data, there is a strong correlation between income per capita and mortality rates, a correlation that also exists within countries, where richer, better-educated people live longer. We review the determinants of these patterns: over history, over countries, and across groups within countries. While there is no consensus about the causal mechanisms, we tentatively identify the application of scientific advance and technical progress (some of which is induced by income and facilitated by education) as the ultimate determinant of health. Such an explanation allows a consistent interpretation of the historical, cross-country, and within-country evidence. We downplay direct causal mechanisms running from income to health.

Fiscal decentralization and the challenge of hard budget constraints

Abstract: In many parts of the world, lower levels of government are taking over responsibilities from national authorities. This often leads to difficulty in maintaining fiscal discipline. So-called soft budget constraints allow these subnational governments to expand expenditures without facing the full cost. Until now, however, there has been little understanding of how decentralization leads to large fiscal deficits and macroeconomic instability.This book, based on a research project at the World Bank, develops an analytical framework for considering the issues related to soft budget constraints, including the institutions, history, and policies that drive expectations for bailouts among subnational governments. It examines fiscal, financial, political, and land market mechanisms for subnational discipline in Argentina, Brazil, Canada, China, Germany, Hungary, India, Norway, South Africa, Ukraine, and the United States.The book concludes that the dichotomy between market and hierarchical mechanisms is false. Most countries--and virtually all developing countries--must rely on market mechanisms as well as hierarchical constraints to maintain fiscal discipline. When bailouts cannot be avoided, they present important opportunities to reform underlying institutions. Successful market discipline--where voluntary lenders perform important monitoring functions--is most likely to emerge from a gradual process that begins with carefully crafted rules and oversight.

Worldwide Variation in Human Growth

Abstract: This is a very large compilation of growth data with an extremely wide coverage of population groups, many of which will be completely unknown to all but the professional ethnographer. There is, however, a disappointingly narrow coverage of variables (length, weight, body widths, circumferences and proportions, skinfold thicknesses, and maturity). Many of the findings are relevant to an important question: should one set of growth reference data be used throughout the world, thus allowing ready comparability between groups, or should there be separate sets for each major racial group or even a multitude of local sets? The studies summarized in this volume indicate many population groups have similar potentials for growth in major body dimensions. For example, the narrower range of means among European than among African groups that range from "tribal" to well-off indicates the range of variation in growth would be reduced greatly if the environmental circumstances allowed
