The Canadian sample for labour force and other population data

An area sample is now being taken quarterly in Canada for labour force and a wide variety of other population data. Since reliable lists of households cannot be obtained without substantial expense the amount of field work is reduced to a minimum by the use of maps which may be thought of as an implicit listing. Random selection with known probabilities is applied in several stages, the overall result being a 1 % sample of the population. The survey data provide not only estimates of unemployment, movement of population, etc., but also give the errors of estimate. During the 3 years of its operation, information has been obtained for government and public use on housing conditions, rents, farm fires and accidents, sickness, fish consumption and many other matters.     

The athlete as model minority subject: Jose Bautista and Canadian multiculturalism

The discourse of multiculturalism disguises complicated racial dynamics in nations such as Canada. Although white privilege persists, it tends to be mediated through non-white figures who can engender consent from other minority members. These figures have been called model minorities, a role that is well-tailored to celebrated athletes. Athletes who fill the role of model minority represent the ideal immigrant citizen: English-speaking, middle class/bourgeois, disciplined, and hard-working. As such, they serve a disciplinary function for other immigrants by demonstrating how it is they should act and producing a standard against which they are evaluated. The model minority has become a crucial representational figure for multicultural nations like Canada because the political economy of these states requires cheap labour that can be hyper-exploited through the dehumanization of racialization. Drawing on articles in Toronto's most prominent newspapers, I argue that Toronto Blue Jays baseball star Jose Bautista has recently assumed the status of a model minority. I elaborate the functions of the model minority through a reading of Bautista's representation.     

Health and the educational attainment of adolescents: evidence from the NLSY97

This article examines the mechanisms linking health to the educational attainment of adolescents. In particular it investigates the role of cognitive/academic achievement and a variety of psychosocial adjustment factors in explaining this relationship. Using data from the National Longitudinal Survey of Youth 1997 cohort (NLSY97), we estimate models of timely high school completion and of post-secondary enrollment using both standard logit estimation and sibling fixed-effects models. We find that, net of sociodemographic background and stable unobserved family characteristics, adolescents who experience worse health are substantially less likely to complete high school by their 20th birthday and to transition to post-secondary education. Cognitive/academic achievement and psychosocial factors appear to explain a large portion of these health-related educational deficits. However adolescent health continues to be significantly associated with these key educational transitions. The findings highlight a potentially important role of health selection processes in generating socioeconomic inequalities in early adolescence to young adulthood.     

The quality–quantity trade-off in fertility across parent earnings levels: a test for credit market failure

The dominant economic theory of the family explains the negative correlation between family size and child achievement, a ‘quality–quantity trade-off’, through borrowing constraints and credit market failure. This paper presents a model in which the opportunity cost of time spent with children is increasing, thus creating a trade-off even in economies with perfect credit markets. While both produce a family size effect, temporal and financial constraints predict different patterns for the trade-off across levels of parent income. Using data from the National Child Development Study, the trade-off is found even among high-earning families who presumably do not face credit constraints. Moreover, the trade-off does not grow as parent earnings diminish. Both of these findings suggest that temporal and not financial constraints explain the quality–quantity trade-off.

A unified approach to interpolation and graduation

The subject of interpolation and graduation is customarily treated by finite difference formulas of great variety and complexity, these having been developed with the convenience of hand calculation in mind. The cheapening of computation which has occurred in the past few years permits a simplification and unification of the subject. This is accomplished by linear equations which express conditions it is desired to impose on the interpolating curve and the elimination of the constants resulting in a determinantal equation. A computer program which evaluates a determinant then suffices for nearly any problem of graduation, interpolation, numerical differentiation and integration, as well as for the calculation of the remainder term or error of any of these.     

Changing vital rates and age distributions

Abstract In a time of rapid change in birth and death rates demographers need to know the consequences of such changes for age distribution. Does the fall in death rates tend to make the age distribution older? It certainly enables individuals to grow older, but for population aggregates the effect depends on the ages at which mortality improves. Coale, Stolnitz, Schwarz, Lorimer, the United Nations and other writers have investigated trends in age-specific birth and death rates. In particular they have demonstrated that the falling mortality which is now nearly universal does not generally make the population older and sometimes makes it younger. The present article contributes a technique for further examination of this phenomenon.     

Two Population-Environment Regimes in the Great Plains of the United States, 1930–1990

This paper analyzes factors that affect net migration rates in counties in the U.S. Great Plains between 1930 and 1990, emphasizing the roles of weather (especially drought), environmental amenities, employment, and population, making use of a rich county-level data set. Using a pooled time series model the paper shows that environment is important in population processes, with weather and agricultural change more important in the 1930s and 1940s, and environmental amenities more important in later time periods. The paper provides important insights into how environmental impacts on migration might change over time, and how those changes might be measured.     

Population growth, development and the environment

When Population Studies was founded in 1946 a main preoccupation of demographers and of the public was the prospective decline of the British population, and the falling off of its quality because on the average a poor family had more children than a better-off one. Over the course of the 50 years interests have shifted to the aging of populations as births decline and mortality improves; immigration, immigrants being welcomed for the decades after the war, and subsequently facing hostile political pressures; environmental degradation and the spread of new diseases. The fall in the birth rate, required both for development and for protection of the environment, is spreading from the original industrialized countries of Europe and America to Asia, somewhat more slowly to Latin America, slowest of all to Africa.
