41. Estimating agreement coefficients from sample survey data Archived
Articles and reports: 12-001-X201200111686
Description:
We present a generalized estimating equations approach for estimating the concordance correlation coefficient and the kappa coefficient from sample survey data. The estimates and their accompanying standard error need to correctly account for the sampling design. Weighted measures of the concordance correlation coefficient and the kappa coefficient, along with the variance of these measures accounting for the sampling design, are presented. We use the Taylor series linearization method and the jackknife procedure for estimating the standard errors of the resulting parameter estimates. Body measurement and oral health data from the Third National Health and Nutrition Examination Survey are used to illustrate this methodology.

42. Cities and Growth: Moving to Toronto - Income Gains Associated with Large Metropolitan Labour Markets Archived
Articles and reports: 11-622-M2012023
Geography: Canada
Description:
This paper examines the process by which migrants experience gains in earnings subsequent to migration and, in particular, the advantage that migrants obtain from moving to large, dynamic metropolitan labour markets, using Toronto as a benchmark. There are two potentially distinct patterns to gains in earnings associated with migration. The first is a step upwards in which workers realize immediate gains in earnings subsequent to migration. The second is accelerated gains in earnings subsequent to migration. Immediate gains are associated with obtaining a position in a more productive firm and/or a better match between worker skills and abilities and job tasks. Accelerated gains in earnings are associated processes that take time, such as learning or job switching as workers and firms seek out better matches. Evaluated here is the expectation that the economies of large metropolitan areas provide workers with an initial productive advantage stemming from a one-time improvement in worker productivity and/or a dynamic that accelerates gains in earnings over time through the potentially entwined processes of learning and matching. A variety of datasets and methodologies, including propensity score matching, are used to evaluate patterns of income gains associated with migration to Toronto.

45. Variance estimation under composite imputation: The methodology behind SEVANI Archived
Articles and reports: 12-001-X201100211605
Description:
Composite imputation is often used in business surveys. The term "composite" means that more than a single imputation method is used to impute missing values for a variable of interest. The literature on variance estimation in the presence of composite imputation is rather limited. To deal with this problem, we consider an extension of the methodology developed by Särndal (1992). Our extension is quite general and easy to implement provided that linear imputation methods are used to fill in the missing values. This class of imputation methods contains linear regression imputation, donor imputation and auxiliary value imputation, sometimes called cold-deck or substitution imputation. It thus covers the most common methods used by national statistical agencies for the imputation of missing values. Our methodology has been implemented in the System for the Estimation of Variance due to Nonresponse and Imputation (SEVANI) developed at Statistics Canada. Its performance is evaluated in a simulation study.

46. Adaptive network and spatial sampling Archived
Articles and reports: 12-001-X201100211607
Description:
This paper describes recent developments in adaptive sampling strategies and introduces new variations on those strategies. Recent developments described included targeted random walk designs and adaptive web sampling. These designs are particularly suited for sampling in networks; for example, for finding a sample of people from a hidden human population by following social links from sample individuals to find additional members of the hidden population to add to the sample. Each of these designs can also be translated into spatial settings to produce flexible new spatial adaptive strategies for sampling unevenly distributed populations. Variations on these sampling strategies include versions in which the network or spatial links have unequal weights and are followed with unequal probabilities.

47. Ten years of balanced sampling with the cube method: An appraisal Archived
Articles and reports: 12-001-X201100211609
Description:
This paper presents a review and assessment of the use of balanced sampling by means of the cube method. After defining the notion of balanced sample and balanced sampling, a short history of the concept of balancing is presented. The theory of the cube method is briefly presented. Emphasis is placed on the practical problems posed by balanced sampling: the interest of the method with respect to other sampling methods and calibration, the field of application, the accuracy of balancing, the choice of auxiliary variables and ways to implement the method.

49. A Profile of Canadian Importers, 2002 to 2009 Archived
Articles and reports: 65-507-M2011011
Description:
This issue presents statistics, derived from the Importer Register Database, on importing establishments for the years 2002 to 2009. This Importer Register Database provides importer statistics such as the number of importers and the value of their imports by industry, importer size, origin and province of residence.
The establishment is the statistical unit of measure. Consequently, any reference made here to "importers" represents "statistical establishments that imported." Inclusion in the database requires that an establishment has imported merchandise in at least one year from 2002 to 2009. If an establishment does not import in a given year, that establishment is not included in the Register for that year.
This report is divided into four sections: "Highlights" consist of an overview of results of the 2009 Importer Register Database; "Findings" contains more detailed analyses of the Importer Register Database; "Methodology, Data concepts and definitions" outlines the estimation methods and limitations as well as the fundamental principles of the Importer Register Database; and "Data tables" contain tabular data for the years from 2002 to 2009.

192. Technology-induced Wage Premia in Canadian Manufacturing Plants During the 1980s Archived
Articles and reports: 11F0019M1996092
Geography: Canada
Description:
This study is one of a series that examines how technology adoption affects the skills of workers. Previous papers in the series have approached this issue in differentways with data from a variety of sources. Using data on the strategies and activities of small and medium-sized firms in both manufacturing and services industries,Baldwin and Johnson (1995), Baldwin, Johnson and Pedersen (1996) examine the connection between the different strategies that are pursued by growing firms.Firms that stress technological competencies are found to also place a greater emphasis on skill enhancement and training activities. Using survey data on the type oftechnology used in manufacturing plants and plant managers' perceptions of the skill requirements and training costs associated with the adoption of newtechnologies, Baldwin, Gray and Johnson (1995) find that technology use leads to greater skill requirements, more training, and higher training costs.This paper uses survey data on the incidence of advanced technology adoption and matched panel data on plant characteristics such as wages, capital intensity, andsize to examine the connection between technology use and the wage rates received by workers. Since higher wages are associated with higher skill levels,establishing a connection between technology use and wages reinforces the earlier findings.

194. Sample design of the National Population Health Survey Archived
Articles and reports: 82-003-X19950011661
Geography: Canada
Description:
In 1994, Statistics Canada began data collection for the National Population Health Survey (NPHS), a household survey designed to mesure the health status of Canadians and to expand knowledge of health determinants. The survey is longitudinal, with data being collected on selected panel members every second year. This article focuses on the NPHS sample design ant its rationale. Topics include sample allocation, representativeness, and selection; modifications in Quebec and the territories; and integration of the NPHS with the National Longitudinal Survey of Children. The final section considers some methodological issues to be addresses in future waves of the survey.

195. Impact of new population estimates on health and vital statistics Archived
Articles and reports: 82-003-X19950011662
Geography: Canada
Description:
Changes in Statistics Canada's annual population estimates, introduced in 1993, have an impact on a wide range of social, economic and demographic indicators. Any indicator that relies on population estimates will be affected by the new figures. This article describes the adjustment and examines its impact on health and vital statistics rates. With rare exceptions, all rates decrease as the denominators are adjusted upward. For example, accident rates, suicide rates, and age-specific fertility rates based on the adjustment population are lower than those previously calculated. The extent of the adjustment, however, depends on the geographic and demographic characteristics of the population at risk. Analysts whose work concentrates on special subgroups for whom the adjustment is particularly great (such as young adult men) may wish to pay closer attention to the new population figures. Although the new rates are lower than before, underlying trends and patterns over time or across subcategories are quite similar. The revised series incorporates estimates of net census undercoverage, and for the first time, includes non-permanent residents. In 1991, net census undercoverage and non-permanent residents together amounted to about one million persons, or 3.6% of the revised Canadian population of 28,120,100.

196. Have Small Firms Created a Disproportionate Share of New Jobs in Canada? A Reassessment of the Facts Archived
Articles and reports: 11F0019M1994071
Geography: Canada
Description:
The statistical observation that small firms have created the majority of new jobs during the 1980s has had a tremendous influence on public policy. Governmentshave looked to the small firm sector for employment growth, and have promoted policies to augment this expansion. However, recent research in the US suggeststhat net job creation in the small firm sector may have been overestimated, relative to that in large firms. This paper addresses various measurement issues raised inthe recent research, and uses a very unique Canadian longitudinal data set that encompasses all companies in the Canadian economy to reassess the issue of jobcreation by firm size. We conclude that over the 1978-92 period, for both the entire Canadian economy and the manufacturing sector, the growth rate of (net)employment decreases monotonically as the size of firm increases, no matter which method of sizing firms is used. The small firm sector has accounted for adisproportionate share of both gross job gains and job losses, and in that aggregate, accounted for a disproportionate share of the employment increase over theperiod. Measurement does matter, however, as the magnitude of the difference in the growth rates of small and large firms is very sensitive to the measurementapproaches used. The paper also produces results for various industrial sectors, asks whether the more rapid growth in industries with a high proportion of smallfirms is responsible for the findings at the all-economy level, and examines employment growth in existing small and large firms (ie excluding births). It is found thatemployment growth in the population of existing small and large firms is very similar.
