The 2005 National Survey of the Work and Health of Nurses (NSWHN) represents a collaborative effort involving the Canadian Institute for Health Information, Health Canada, and Statistics Canada.

The NSWHN was designed to examine links between the work environment and the health of regulated nurses in Canada, and is the first nationally representative survey of its kind. The survey's high response rate (80%) reflects the enthusiasm with which nurses involved themselves in the survey.

Nearly 19,000 regulated nurses, representing registered nurses (RNs), licensed practical nurses (LPNs) and registered psychiatric nurses (RPNs) across the country were interviewed on a variety of topics, including the conditions in which they practice, the challenges they face in doing their jobs, and their physical and mental wellbeing.

They shared their perceptions of work organization, including staffing, shift work, overtime and employee support. Nurses were also asked about work stress, role overload, respect, and quality of patient care. Information about their health status, such as chronic conditions, pain, self-perceived general and mental health, medication use, and the impact of health on the performance of nursing duties, was also collected.

This document presents key findings from the 2005 NSWHN for each province, as well as for the three territories combined.

This paper documents how changes in the rules of trade have affected the clothing market. Free trade with the US initially was a boon to domestic output and jobs. Imports from less-developed countries increased in the 1990s, but the entry of China into the WTO saw the displacement of many of these countries, as well as domestic producers. Consumers reaped the benefit of cheaper imports.

This report provides an overview of the results of the Survey of Financial Security (SFS). This survey collected information on the assets and debts of families and unattached individuals. Data collection took place from May to July 2005, in all provinces.

The 2005 SFS provides a comprehensive picture of the wealth of Canadians. Information was collected on the value of all major financial and non-financial assets and on the money owing on mortgages, vehicles, credit cards, student loans and other debts. The value of these assets less the debts is referred to in this report as net worth.

Held in Ottawa, Canada, in September 2006, the Blue Sky II Forum examined new areas for indicator development and set a broad agenda for future work on science, technology and innovation (STI) indicators. Emphasis was placed on indicators of outcomes and impacts in order to support monitoring, benchmarking, foresight, and evaluation activities, applied to policies and programs, and their economic and social impacts. As expected the Forum provided ideas and guidance for indicators work in both OECD-member and non-member countries as well as for other international organizations.

Canadian universities and affiliated research hospitals have made great strides in commercializing inventions. Since 1998 Statistics Canada has conducted the Survey of Intellectual Property Commercialization in the Higher Education Sector to track progress in this area. This article highlights some of the changes between 2003 and 2004, as well as presenting the 2004 regional results.

Data from the Research and Development in Canadian Industry Survey reveal that between 1994 and 2002 - 31,190 enterprises undertook research and development (R&D) activities for at least one year. However, only 5% (1,699) can be considered persistent R&D performers, appearing on the R&D in Canadian Industry database for nine years. It appears that the size of the R&D expenditure groups that firms belong to influences their level of persistence in R&D performance. This article investigates that premise.

Over the past decade, Internet content has evolved to the point where it now represents a significant source of information and entertainment for many people. The Internet has changed the way that many individuals and organizations gather information, and has undoubtedly had some influence on their use of traditional media. While few Canadians had Internet access and went online to gather news information in the mid-1990's, today many use the Internet to access online newspapers, reports, discussion forums and even blogs. In 2005 for example, about 62% of home Internet users - or 38% of Canadian adults overall - went online to view news or sports information (Statistics Canada 2006).

Bioproducts play an important role in the search for solutions to declining reserves of oil, increasing costs of oil extraction, increasing oil prices and increasing greenhouse gas (GHG) concentration. They also offer opportunities for rural economic development and diversification for farmers. This article summarizes ongoing work towards improving our understanding of the bioproduct concepts and their definitions.

Over the past six years, the Government of Canada has worked toward providing services online for corporations, clients and citizens alike. By 2005, the initiative had resulted in 130 of the most commonly used services being available online to complement more traditional means of delivery. This article provides highlights from Statistics Canada's 2005 Survey of Electronic Commerce and Technology (SECT) which investigated federal and provincial government online services.

This article describes a pilot study conducted on companies who were clients of the NRC-IRAP British Columbia Region between 1987 and 1998. Growth indicators were produced for the period 1998 to 2002. Findings will enable NRC-IRAP to engage in evidence-based assessment of their disbursement of public funds, report on the effectiveness of the program, and make decisions regarding program amendment in light of measured outcomes.

We discuss methods for the analysis of case-control studies in which the controls are drawn using a complex sample survey. The most straightforward method is the standard survey approach based on weighted versions of population estimating equations. We also look at more efficient methods and compare their robustness to model mis-specification in simple cases. Case-control family studies, where the within-cluster structure is of interest in its own right, are also discussed briefly.

Calibration weighting can be used to adjust for unit nonresponse and/or coverage errors under appropriate quasi-randomization models. Alternative calibration adjustments that are asymptotically identical in a purely sampling context can diverge when used in this manner. Introducing instrumental variables into calibration weighting makes it possible for nonresponse (say) to be a function of a set of characteristics other than those in the calibration vector. When the calibration adjustment has a nonlinear form, a variant of the jackknife can remove the need for iteration in variance estimation.

The theory of multiple imputation for missing data requires that imputations be made conditional on the sampling design. However, most standard software packages for performing model-based multiple imputation assume simple random samples, leading many practitioners not to account for complex sample design features, such as stratification and clustering, in their imputations. Theory predicts that analyses of such multiply-imputed data sets can yield biased estimates from the design-based perspective. In this article, we illustrate through simulation that (i) the bias can be severe when the design features are related to the survey variables of interest, and (ii) the bias can be reduced by controlling for the design features in the imputation models. The simulations also illustrate that conditioning on irrelevant design features in the imputation models can yield conservative inferences, provided that the models include other relevant predictors. These results suggest a prescription for imputers: the safest course of action is to include design variables in the specification of imputation models. Using real data, we demonstrate a simple approach for incorporating complex design features that can be used with some of the standard software packages for creating multiple imputations.

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.

In this paper, the geometric, optimization-based, and Lavallée and Hidiroglou (LH) approaches to stratification are compared. The geometric stratification method is an approximation, whereas the other two approaches, which employ numerical methods to perform stratification, may be seen as optimal stratification methods. The algorithm of the geometric stratification is very simple compared to the two other approaches, but it does not take into account the construction of a take-all stratum, which is usually constructed when a positively skewed population is stratified. In the optimization-based stratification, one may consider any form of optimization function and its constraints. In a comparative numerical study based on five positively skewed artificial populations, the optimization approach was more efficient in each of the cases studied compared to the geometric stratification. In addition, the geometric and optimization approaches are compared with the LH algorithm. In this comparison, the geometric stratification approach was found to be less efficient than the LH algorithm, whereas efficiency of the optimization approach was similar to the efficiency of the LH algorithm. Nevertheless, strata boundaries evaluated via the geometric stratification may be seen as efficient starting points for the optimization approach.

To select a survey sample, it happens that one does not have a frame containing the desired collection units, but rather another frame of units linked in a certain way to the list of collection units. It can then be considered to select a sample from the available frame in order to produce an estimate for the desired target population by using the links existing between the two. This can be designated by Indirect Sampling.

Estimation for the target population surveyed by Indirect Sampling can constitute a big challenge, in particular if the links between the units of the two are not one-to-one. The problem comes especially from the difficulty to associate a selection probability, or an estimation weight, to the surveyed units of the target population. In order to solve this type of estimation problem, the Generalized Weight Share Method (GWSM) has been developed by Lavallée (1995) and Lavallée (2002). The GWSM provides an estimation weight for every surveyed unit of the target population.

This paper first describes Indirect Sampling, which constitutes the foundations of the GWSM. Second, an overview of the GWSM is given where we formulate the GWSM in a theoretical framework using matrix notation. Third, we present some properties of the GWSM such as unbiasedness and transitivity. Fourth, we consider the special case where the links between the two populations are expressed by indicator variables. Fifth, some special typical linkages are studied to assess their impact on the GWSM. Finally, we consider the problem of optimality. We obtain optimal weights in a weak sense (for specific values of the variable of interest), and conditions for which these weights are also optimal in a strong sense and independent of the variable of interest.

A survey of tourist visits originating intra and extra-region in Brittany was needed. For concrete material reasons, "border surveys" could no longer be used. The major problem is the lack of a sampling frame that allows for direct contact with tourists. This problem was addressed by applying the indirect sampling method, the weighting for which is obtained using the generalized weight share method developed recently by Lavallée (1995), Lavallée (2002), Deville (1999) and also presented recently in Lavallée and Caron (2001). This article shows how to adapt the method to the survey. A number of extensions are required. One of the extensions, designed to estimate the total of a population from which a Bernouilli sample has been taken, will be developed.

Félix-Medina and Thompson (2004) proposed a variant of Link-tracing sampling in which it is assumed that a portion of the population, not necessarily the major portion, is covered by a frame of disjoint sites where members of the population can be found with high probabilities. A sample of sites is selected and the people in each of the selected sites are asked to nominate other members of the population. They proposed maximum likelihood estimators of the population sizes which perform acceptably provided that for each site the probability that a member is nominated by that site, called the nomination probability, is not small. In this research we consider Félix-Medina and Thompson's variant and propose three sets of estimators of the population sizes derived under the Bayesian approach. Two of the sets of estimators were obtained using improper prior distributions of the population sizes, and the other using Poisson prior distributions. However, we use the Bayesian approach only to assist us in the construction of estimators, while inferences about the population sizes are made under the frequentist approach. We propose two types of partly design-based variance estimators and confidence intervals. One of them is obtained using a bootstrap and the other using the delta method along with the assumption of asymptotic normality. The results of a simulation study indicate that (i) when the nomination probabilities are not small each of the proposed sets of estimators performs well and very similarly to maximum likelihood estimators; (ii) when the nomination probabilities are small the set of estimators derived using Poisson prior distributions still performs acceptably and does not have the problems of bias that maximum likelihood estimators have, and (iii) the previous results do not depend on the size of the fraction of the population covered by the frame.

Survey sampling to estimate a Consumer Price Index (CPI) is quite complicated, generally requiring a combination of data from at least two surveys: one giving prices, one giving expenditure weights. Fundamentally different approaches to the sampling process - probability sampling and purposive sampling - have each been strongly advocated and are used by different countries in the collection of price data. By constructing a small "world" of purchases and prices from scanner data on cereal and then simulating various sampling and estimation techniques, we compare the results of two design and estimation approaches: the probability approach of the United States and the purposive approach of the United Kingdom. For the same amount of information collected, but given the use of different estimators, the United Kingdom's methods appear to offer better overall accuracy in targeting a population superlative consumer price index.

The Survey of Income and Labour Dynamics (SLID) interview is conducted using computer-assisted interviewing (CAI). CAI is paperless interviewing. This document is therefore a written approximation of the CAI interview, or the questionnaire.

In previous years, SLID conducted a Labour interview each January and a separate Income interview in May. In 2005 (reference year 2004) the two interviews were combined and collected in one interview in January.

A labour and income interview is collected for all respondents 16 years of age and over. Respondents have the option of answering income questions during the interview, or of giving Statistics Canada permission to use their income tax records.

In January 2005, data was collected for reference year 2004 from panels 3 and 4. Panel 3, in its sixth and final year, consisted of approximately 17,000 households and panel 4, in its third year, also consisted of approximately 17,000 households.

This document outlines the structure of the January 2005 Labour and Income interview (for the 2004 reference year) including question wording, possible responses, and flows of questions.

This document examines the functional limitations, physical, emotional and social, related to the musculoskeletal conditions having the largest impact on the health of Canadians. These functional limitations are described and classified using the Classification and Measurement System of Functional Health (CLAMES).

These descriptions and classifications are the first step in a new approach to measuring the health of Canadians that examines what factors are adversely affecting population health and how to address them. This document also provides health professionals, advocacy groups, and individual Canadians with an overview of how living with certain musculoskeletal conditions affects day-to-day functioning.

In previous years, the Survey of Labour and Income Dynamics (SLID) conducted a Labour interview each January and a separate Income interview in May. In 2005 (reference year 2004) the two interviews were combined and collected in one interview in January.

The data are collected using computer-assisted interviewing. Thus there are no paper questionnaires required for data collection. The questions, responses and interview flow for Labour and Income are documented in other SLID research papers. This document presents the information for the 2005 Entry Exit portion of the Labour Income interview (for the 2004 reference year).

The Entry Exit Component consists of five separate modules. The Entry module is the first set of data collected. It is information collected to update the place of residence, housing conditions and expenses, as well as the household composition. For each person identified in Entry, the Demographics module collects (or updates) the person's name, date of birth, sex and marital status. Then the Relationships module identifies (or updates) the relationship between each respondent and every other household member. The Exit module includes questions on who to contact for the next interview and the names, phone numbers and addresses of two contacts to be used only if future tracing of respondents is required. An overview of the Tracing component is also included in this document.

Statistics Canada collects and publishes a large amount of data on all modes of transportation. For example, do you know the level of shipments of commodities last quarter? Where are the key access points to the United States and which commodities are moving through them? How can you determine market share? This guide will familiarize you with the sources for answers to these questions and more and show you how to access them. It will allow you to take advantage of what Statistics Canada has to offer you. The guide is divided into two parts. Part I contains a description of each survey at Statistics Canada that has transportation related information. Each survey is listed with the survey name, a person to contact, phone number and fax number, a brief description of the transportation related information in the survey, the periodicity of the survey and the publication catalogue number, name and price where the information can be found.
