Analysis

Description: Pseudo weight construction for data integration can be understood in the two-phase sampling framework. Using the two-phase sampling framework, we discuss two approaches to the estimation of propensity scores and develop a new way to construct the propensity score function for data integration using the conditional maximum likelihood method. Results from a limited simulation study are also presented.

Description: Nonprobability samples emerge rapidly to address time-sensitive priority topics in different areas. These data are timely but subject to selection bias. To reduce selection bias, there has been wide literature in survey research investigating the use of propensity-score (PS) adjustment methods to improve the population representativeness of nonprobability samples, using probability-based survey samples as external references. Conditional exchangeability (CE) assumption is one of the key assumptions required by PS-based adjustment methods. In this paper, I first explore the validity of the CE assumption conditional on various balancing score estimates that are used in existing PS-based adjustment methods. An adaptive balancing score is proposed for unbiased estimation of population means. The population mean estimators under the three CE assumptions are evaluated via Monte Carlo simulation studies and illustrated using the NIH SARS-CoV-2 seroprevalence study to estimate the proportion of U.S. adults with COVID-19 antibodies from April 01-August 04, 2020.

Description: Our comments respond to discussion from Sen, Brick, and Elliott. We weigh the potential upside and downside of Sen’s suggestion of using machine learning to identify bogus respondents through interactions and improbable combinations of variables. We join Brick in reflecting on bogus respondents’ impact on the state of commercial nonprobability surveys. Finally, we consider Elliott’s discussion of solutions to the challenge raised in our study.

Description: This discussion summarizes the interesting new findings around measurement errors in opt-in surveys by Kennedy, Mercer and Lau (KML). While KML enlighten readers about “bogus responding” and possible patterns in them, this discussion suggests combining these new-found results with other avenues of research in nonprobability sampling, such as improvement of representativeness.

Description: Kennedy, Mercer, and Lau explore misreporting by respondents in non-probability samples and discover a new feature, namely that of deliberate misreporting of demographic characteristics. This finding suggests that the “arms race” between researchers and those determined to disrupt the practice of social science is not over and researchers need to account for such respondents if using high-quality probability surveys to help reduce error in non-probability samples.

Description: Nonprobability samples are quick and low-cost and have become popular for some types of survey research. Kennedy, Mercer and Lau examine data quality issues associated with opt-in nonprobability samples frequently used in the United States. They show that the estimates from these samples have serious problems that go beyond representativeness. A total survey error perspective is important for evaluating all types of surveys.

Description: Statistical approaches developed for nonprobability samples generally focus on nonrandom selection as the primary reason survey respondents might differ systematically from the target population. Well-established theory states that in these instances, by conditioning on the necessary auxiliary variables, selection can be rendered ignorable and survey estimates will be free of bias. But this logic rests on the assumption that measurement error is nonexistent or small. In this study we test this assumption in two ways. First, we use a large benchmarking study to identify subgroups for which errors in commercial, online nonprobability samples are especially large in ways that are unlikely due to selection effects. Then we present a follow-up study examining one cause of the large errors: bogus responding (i.e., survey answers that are fraudulent, mischievous or otherwise insincere). We find that bogus responding, particularly among respondents identifying as young or Hispanic, is a significant and widespread problem in commercial, online nonprobability samples, at least in the United States. This research highlights the need for statisticians working with commercial nonprobability samples to address bogus responding and issues of representativeness – not just the latter.

The correlation of occupational gender composition and wages is the basis of pay equity/comparable worth legislation. A number of previous studies have examined this correlation in US data, identifying some of the determinants of low wages in "female jobs", as well as important limitations of public policy in this area. There is little evidence, however, from other jurisdictions. This omission is particularly disturbing in the case of Canada, which now has some of the most extensive pay equity legislation in the world. In this paper, we provide a comprehensive picture, circa the late 1980's, of the occupational gender segregation in Canada and its consequences for wages. We also draw explicit comparisons of our findings to evidence for the United States. We find that the link between female wages and gender composition is much stronger in the United States than in Canada, where it is generally small and not statistically significant. The relatively more advantageous position of women in female jobs in Canada is found to be linked to higher unionization rates and the industry-wage effects of "public goods" sectors.

This paper addresses the topic of inter-provincial migration in terms of the basic question: "who moves?" Panel logit models of the probability of moving from one year to the next are estimated using samples derived from the Longitudinal Administrative Database covering the period 1982-95. Explanatory variables include "environmental" factors, personal characteristics, labour market attributes, and a series of year variables. Separate models are estimated for eight age-sex groups.

The major findings include that: i) migration rates have been inversely related to the size of the province, presumably capturing economic conditions, labour market scale effects, and pure geographical distance, while language has also played an important role; ii) residents of smaller cities, towns, and especially rural areas have been less likely to move than individuals in larger cities; iii) age, marriage, and the presence of children have been negatively related to mobility, for both men and women; iv) migration has been positively related to the provincial unemployment rate, the individuals' receipt of unemployment insurance (except Entry Men), having no market income (except for Entry Men and Entry Women), and the receipt of social assistance (especially for men); v) beyond the zero earnings point, migration has been positively related to earnings levels for prime aged men, but not for others, and these effects are generally small (holding other factors constant); vi) there were no dramatic shifts in migration rates over time, but men's rates dropped off a bit in the 1990s while women's rates (except for the Entry group) generally held steadier or rose slightly, indicating a divergence in trends along gender lines.

There has been for some time substantial concern regarding the loss of young people in rural communities. There is a sense that most rural communities offer few opportunities for their younger people, requiring them to leave for urban communities, most likely not to return. While there is a considerable body of research on interprovincial migration, relatively little is currently known about migration patterns in rural and urban areas in Canada.

According to our analysis, in virtually all provinces young people 15 to 19 years of age are leaving rural areas in greater proportions than urban areas - in part to pursue post-secondary education. While there are more complex migration patterns affecting the 20-29 age group, the net result of all migration is that the Atlantic provinces - as well as Manitoba and Saskatchewan - are net losers of their rural population aged 15-29. The problem is particularly acute in Newfoundland. In the Atlantic provinces, rural areas which fare worse than the national average - in terms of net gains of youth population - do so not because they have a higher than average percentage of leavers but rather because they are unable to attract a sufficiently high proportion of individuals into their communities.

Of all individuals who move out of their rural community, at most 25% return to this community ten years later. The implication of this result is clear: one cannot count on return migration as a means of preserving the population size of a given cohort. Rather, rural areas must rely on inflows from other (urban) areas to achieve this goal. Some rural communities achieve this; that is, they register positive net in-migration of persons aged 25-29 or older, even though they incur a net loss of younger people.

Individuals who move out of rural areas generally experience higher earnings growth than their counterparts who stay. However, it remains an open question in which direction the causality works: is the higher earnings growth the result of the migration process itself or does it reflect the possibility that people with higher earnings growth potential are more likely to become movers?

The Survey of Household Spending (SHS), which replaced the periodic Family Expenditure Survey (FAMEX) in 1997, is an annual survey that collects detailed expenditure information from households for a given calendar year. Due to the heavy response burden placed on respondents of this survey, it was decided for the 1997 survey to perform a test of incentive effect on response rates. Two incentives were used: a one-year subscription to the Statistics Canada publication Canadian Social Trends and a telephone calling card. The response rate data was analysed using Fisher's exact test and some non-parametric methods. After controlling for a discovered interviewer assignment effect, it was found that there was some evidence of a telephone card effect in the western and eastern most regions of Canada, while there was no evidence of any effect for the magazine. These findings were somewhat corroborated by a separate study testing effects of incentives on respondent relations. All these results will be discussed in this paper.

The contributors to this book examine two broad themes related to the well-being of Canadian youth. First, they document the nature of the labour market facing young adults and how it has changed since the early 1970s. Second, the authors examine how families, communities, and the public sector influence some of the ways in which children become successful and self-reliant adults. The motivation for bringing these essays together has to do with the increasing importance of child well-being in public discourse and the development of public policy. The major message to emerge is that the future of Canada's children is both a good news, and a bad news story. Labour markets have changed dramatically, and on average it is now more difficult to obtain a strong foothold that will lead to increasing prosperity. Many young Canadians, however, are well prepared by their family and community backgrounds to deal with these new challenges, and as young parents are in a position to pass this heritage on to their children. However, this has not been the case for an increasingly larger minority, a group whose children in turn may face greater than average challenges in getting ahead in life. A companion volume published in February of 1998 by Statistics Canada called Government finances and generational equity examines the operation of government taxes and transfers from a generational perspective, focusing on the conduct of fiscal policy and the relative status of individuals in successive generations.

These highlights provide a brief summary of the report " The Value of Words: Literacy and Economic Security in Canada", the latest monograph released using data from the International Adult Literacy Survey. Canada, like many other industrialized countries, is increasingly being forced to face the literacy problem within its own borders. Over the past decade, the issue has become more prominent on the national policy and research agenda. There has been little systematic research in Canada, however, on the relationship between literacy and income security. Using data from the Canadian component of the International Adult Literacy Survey (IALS), this study seeks to fill this research gap. An in-depth exploration of the links between literacy and economic security will build on existing knowledge and will also provide useful insights that will help shape public policy.

Based on a presentation by Dr. Ivan Fellegi to the Federal Deputy Ministers' Committee on the Economic Renewal of Rural Canada in September l996, Understanding rural Canada uses charts and maps to present information on: rural demography showing population change and net migration by census division for the most recent 5-year period (l989 to l994); a focus on rural youth including information on education attained, plans for further education and ablility to use computers; rural employment, rural unemployment, rural employment in growing sectors and rural employment by small businesses; a classification of census divisions by level of average incomes and change in average incomes to show that many rural areas have lower incomes and their incomes are falling further behind; and, a typology of census divisions where rural areas are classified to rural nirvana areas, agro-rural areas, rural enclave areas, rural resourced areas and native north areas. This presentation was an outgrowth of the publication Rural Canada: a profile published by the federal Interdepartmental Committee on Rural and Remote Canada in March, l995.

Description:

Bankruptcy rates have been increasing in Canada. Almost half of the firms in Canada that go bankrupt do so primarily because of their own deficiencies rather than externally generated problems. They do not develop the basic internal strengths to survive. Overall weakness in management, combined with a lack of market for their product, cause these firms to fail.

This study suggests that the underlying factor contributing to financial difficulties is management failure rather than external factors associated with imperfect capital markets. Many bankrupt firms face problems in attaining financing in capital markets; but, it is the internal lack of managerial expertise in many of these firms that prevents exploration of different financing options.

Description:

"Generational equity" is a topic that has gradually risen higher and higher on the agenda of governments at all levels. In fact, it is a matter not just for government policy, but a topic that touches many Canadians directly: young and old, parents and grandparents. Canadian policy makers increasingly have to deal with issues associated with the relative status of individuals between successive generations. The reform of public pension programs presents the most obvious example, but there are many other developments that raise the same type of issue. Indeed, the heightened concern over government fiscal policies is due in large part to the readiness of many to view government deficits and debt as a burden on future generations. Generational equity, however, is also a concern of individual Canadians and their families. The allocation of resources between the young and the old within the family is becoming an increasingly important issue for many, especially in light not only of an aging population but also the belief that those just entering the labour force will likely not attain the standard of living to which their parents have become accustomed.

The contributors to this book examine the operation of government taxes and expenditures from a generational perspective. In part the motivation for bringing these essays together is to offer comprehensive and up-to-date information on the age incidence of government finances. This motivation, however, also has to do with the development of a new accounting framework, Generational Accounting, that has gained some currency in many industrialized countries, particularly in the United States. It is a truism to say that good analysis requires good data, and certainly Statistic Canada's central role is to offer high-quality data in support of analysis and decision making. But the opposite is equally true, if not as obvious: good data requires good analysis. That is to say, new analytical frameworks often highlight the need to organize existing data in different ways, as well as the need for the development of new types of data. This is certainly one of several reasons that Statistics Canada has sought to develop a strong analytical capacity, and to maintain strong ties with the research community. This book is meant to contribute to this process by examining Canadian data through the lens of Generational Accounting, and by analyzing some of the issues that arise.
