  • Articles and reports: 12-001-X20060029549
    Description:

    In this article, we propose a Bernoulli-type bootstrap method that can easily handle multi-stage stratified designs where sampling fractions are large, provided simple random sampling without replacement is used at each stage. The method provides a set of replicate weights which yield consistent variance estimates for both smooth and non-smooth estimators. The method's strength is in its simplicity. It can easily be extended to any number of stages without much complication. The main idea is to either keep or replace a sampling unit at each stage with preassigned probabilities, to construct the bootstrap sample. A limited simulation study is presented to evaluate performance and, as an illustration, we apply the method to the 1997 Japanese National Survey of Prices.

    Description:

    Researchers and policy makers often use data from nationally representative probability sample surveys. The number of topics covered by such surveys, and hence the amount of interviewing time involved, have typically increased over the years, resulting in increased costs and respondent burden. A potential solution to this problem is to carefully form subsets of the items in a survey and administer one such subset to each respondent. Designs of this type are called "split-questionnaire" designs or "matrix sampling" designs. The administration of only a subset of the survey items to each respondent in a matrix sampling design creates what can be considered missing data. Multiple imputation (Rubin 1987), a general-purpose approach developed for handling data with missing values, is appealing for the analysis of data from a matrix sample, because once the multiple imputations are created, data analysts can apply standard methods for analyzing complete data from a sample survey. This paper develops and evaluates a method for creating matrix sampling forms, each form containing a subset of items to be administered to randomly selected respondents. The method can be applied in complex settings, including situations in which skip patterns are present. Forms are created in such a way that each form includes items that are predictive of the excluded items, so that subsequent analyses based on multiple imputation can recover some of the information about the excluded items that would have been collected had there been no matrix sampling. The matrix sampling and multiple-imputation methods are evaluated using data from the National Health and Nutrition Examination Survey, one of many nationally representative probability sample surveys conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. The study demonstrates the feasibility of the approach applied to a major national health survey with complex structure, and it provides practical advice about appropriate items to include in matrix sampling designs in future surveys.

    Description:

    This article uses data from the 2001 General Social Survey to examine patterns in leaving the parental home. It compares the transition process for five birth cohorts,with the focus on Wave 1 Boomers (born between 1947 and 1956) and their children in Generation X (born between 1967 and 1976). The differences in patterns of leaving the parental home are examined, and then the principal factors associated with a young person's initial launch into adulthood are identified.

    Description:

    It is generally assumed that for most workers, commuting is at best a necessary evil, at worst, a daily nightmare. But is that really the case? Using the latest data from the 2005 General Social Survey on time use, this study identifies the main factors associated with a more or less pleasant commute, focusing in particular on the mode of transportation used.

    Description:

    This article presents information about access to transportation by different age groups; then, it discusses the impact of having either more or less access to transportation on seniors' activities and quality of life. Finally, the article examines the characteristics of those seniors who are most likely to have limited access to transportation, and are thus most likely to face restrictions in their everyday activities.

    Description:

    This report provides an overview of Canadian children as they enter school as 5-year-olds. It looks at the collection of abilities, behaviours and attitudes that they bring with them, attributes that are important for early school achievement. The report shows that children vary on some dimensions of readiness to learn at school, according to their family characteristics, their background and their home environment and experiences. It also shows that some of the differences in readiness to learn may already be evident two years earlier, when the children were 3 years old. Finally, the report indicates factors in the home environment that may contribute to differences among different economic groups. The report adds to what we know about readiness to learn. It provides information that may be useful for policy analysts, teachers, researchers, and parents themselves as they work toward maximizing the potential of preschool children everywhere.

    Description:

    Our vast transportation system - roads, railways, airports, ports and vehicles - provides people and businesses with services that are fundamental to our standard of living and well-being.

    At the same time, transportation is a concern to Canadians from an environmental perspective. From greenhouse gas emissions and air pollution from burning fossil fuels to the fragmentation of wildlife habitat by transportation infrastructure, transportation activities impact the environment locally and globally.

    This article examines transportation activity in Canada and its environmental impacts - and the efforts of governments, businesses and citizens to help mitigate them - by painting a statistical portrait of Transportation in Canada.

    Description:

    This article examines changes in weight over two-year intervals from 1996/1997 to 2004/2005 among Canadians aged 18 to 64 years. Using data from the longitudinal National Population Health Survey (NPHS), average weight change over four two-year intervals was examined for men and women by age group and body mass index (BMI) group. This article is part of the NPHS release and provides links to tables, other research articles and information about the National Population Health Survey.

    Description:

    This paper contains regional and provincial findings from the second wave of the Longitudinal Survey of Immigrants to Canada (LSIC). The LSIC was designed to study how newly arrived immigrants adjust over time to living in Canada.

    This paper focuses on the issue of labour market integration for immigrants at the regional and provincial levels. Labour market integration is a critical aspect of the immigrant settlement process. For the major provinces and Census Metropolitan Areas, this paper addresses questions such as: how long does it take newly arrived immigrants to get their first job? How many of them find employment in their intended occupation? And what obstacles do they encounter when looking for work?
