    Description:

    Researchers are able to examine changes in trends over time, through the examination of responses to repeatedly-asked questions, among the same respondents, over several cycles of longitudinal data. Working with these repeatedly-measured responses can often be challenging. This article examines trends in youth's volunteering activities, using data from the National Longitudinal Survey of Children and Youth, to highlight several issues that researchers should consider when working with repeated measures.

    Description:

    The context of the discussion is the increasing incidence of international surveys, of which one is the International Tobacco Control (ITC) Policy Evaluation Project, which began in 2002. The ITC country surveys are longitudinal, and their aim is to evaluate the effects of policy measures being introduced in various countries under the WHO Framework Convention on Tobacco Control. The challenges of organization, data collection and analysis in international surveys are reviewed and illustrated. Analysis is an increasingly important part of the motivation for large scale cross-cultural surveys. The fundamental challenge for analysis is to discern the real response (or lack of response) to policy change, separating it from the effects of data collection mode, differential non-response, external events, time-in-sample, culture, and language. Two problems relevant to statistical analysis are discussed. The first problem is the question of when and how to analyze pooled data from several countries, in order to strengthen conclusions which might be generally valid. While in some cases this seems to be straightforward, there are differing opinions on the extent to which pooling is possible and reasonable. It is suggested that for formal comparisons, random effects models are of conceptual use. The second problem is to find models of measurement across cultures and data collection modes which will enable calibration of continuous, binary and ordinal responses, and produce comparisons from which extraneous effects have been removed. It is noted that hierarchical models provide a natural way of relaxing requirements of model invariance across groups.

    Description:

    Many countries conduct surveys that focus specifically on their population's health. Because health plays a key role in most aspects of life, health data are also often collected in population surveys on other topics. The subject matter of population health surveys broadly encompasses physical and mental heath, dental health, disabilities, substance abuse, health risk factors, nutrition, health promotion, health care utilization and quality, health coverage, and costs. Some surveys focus on specific health conditions, whereas others aim to obtain an overall health assessment. Health is often an important component in longitudinal studies, particularly in birth and aging cohorts. Information about health can be collected by respondents' reports (for themselves and sometimes for others), by medical examinations, and by collecting biological measures. There is a serious concern about the accuracy of health information collected by respondents' reports. Logistical issues, cost considerations, and respondent cooperation feature prominently when the information is collected by medical examinations. Ethical and privacy issues are often important, particularly when DNA and biomarkers are involved. International comparability of health measures is of growing importance. This paper reviews the methodology for a range of health surveys and will discuss the challenges in obtaining accurate data in this field.

    Description:

    Coverage deficiencies are estimated and analysed for the 2000 population census in Switzerland. For the undercoverage component, the estimation is based on a sample independent of the census and a match with the census. For the overcoverage component, the estimation is based on a sample drawn from the census list and a match with the rest of the census. The over- and undercoverage components are then combined to obtain an estimate of the resulting net coverage. This estimate is based on a capture-recapture model, named the dual system, combined with a synthetic model. The estimators are calculated for the full population and different subgroups, with a variance estimated by a stratified jackknife. The coverage analyses are supplemented by a study of matches between the independent sample and the census in order to determine potential errors of measurement and location in the census data.

    Table: 75-202-X
    Description:

    Income in Canada is an annual analytical report which summarizes the economic well-being of Canadians. It includes an extensive collection of income statistics, covering topics such as income distribution, income tax, government transfers, and low income back to 1976. The data prior to 1993 are drawn from the Survey of Consumer Finances (SCF). Beginning with 1998, the data are taken from the Survey of Labour and Income Dynamnics (SLID). For the 1993 to 1997 period, estimates are based on a combined sample from SCF and SLID.

    Income in Canada provides a complete list of the tables and directions for getting started. It also contains links to the background information on the survey, including content and methodology, and other SLID data products and services.

    With this release, users now have free access to the 202 CANSIM Series tables. Tables are accessible using a PC or Mac via the web browser.

    Description:

    The positive relationship between socioeconomic status (SES) and longevity has long been established. Comparable evidence exists for SES and morbidity, but observations of this relationship tend to be limited to specific health indicators. In this article, a comprehensive quantitative measure of health status, the Health Utility Index (HUI), is applied to an analysis of the relationship between SES the health status of people aged 25 and over in Ontario. The HUI, based on a set of questions included in the 1990 Ontario Health Survey (OHS), provides a summary index of the health of each respondent. The OHS data show that lower levels of education, income, and occupation are associated with lower HUI values. Health status differences across SES groups are greater in late middle-age than at younger or older ages, a pattern consistent with the findings of other studies. The development of summary indicators like the HUI is part of a larger effort to construct measures for monitoring the health of Canadians.

    Description:

    The study of social mobility, between labour market statuses or between income levels, for example, is often based on the analysis of mobility matrices. When comparing these transition matrices, with a view to evaluating behavioural changes, one often forgets that the data derive from a sample survey and are therefore affected by sampling variances. Similarly, it is assumed that the responses collected correspond to the ' true value.'

    Description:

    In longitudinal surveys, sample subjects are observed over several time points. This feature typically leads to dependent observations on the same subject, in addition to the customary correlations across subjects induced by the sample design. Much research in the literature has focussed on modeling the marginal mean of a response as a function of covariates. Liang and Zeger (1986) used generalized estimating equations (GEE), requiring only correct specification of the marginal mean, and obtained standard errors of regression parameter estimates and associated Wald tests, assuming a "working" correlation structure for the repeated measurements on a sample subject. Rotnitzky and Jewell (1990) developed quasi-score tests and Rao-Scott adjustments to "working" quasi-score tests under marginal models. These methods are asymptotically robust to misspecification of the within-subject correlation structure, but assume independence of sample subjects which is not satisfied for complex longitudinal survey data based on stratified multi-stage sampling. We proposed asymptotically valid Wald and quasi-score tests for longitudinal survey data, using the Taylor Linearization and jackknife methods. Alternative tests, based on Rao-Scott adjustments to naive tests that ignore survey design features and on Bonferroni-t, are also developed. These tests are particularly useful when the effective degrees of freedom, usually taken as the total number of sample primary units (clusters) minus the number of strata, is small.
