Stats in brief: 45-20-00032022002
Description:
Canada’s diversity and rich cultural heritage have been shaped by the people who have come from all over the world to call it home. But even in our multicultural society, eliminating all forms of discrimination remains a challenge. In this episode, we turn a critical eye to the ways that cognitive bias risks perpetuating systemic racism. Statistics are supposed to accurately reflect the world around us, but are all data created equal? Join our guests, Sarah Messou-Ghelazzi, Communications Officer, Filsan Hujaleh, Analyst with the Centre for Social Data Insights and Innovation, and Jeff Latimer, Director General - Accountable for Health, Justice, Diversity and Populations at Statistics Canada as we explore the role data can play to make Canada a more equal society for all.

2. Residential Telephone Service Survey Archived
Public use microdata: 56M0001X
Description:
Statistics Canada was approached by Stentor Resource Centre Incorporated to conduct a survey to monitor the telephone penetration rates across Canada. The survey determines if the respondents have a telephone line in their residence. If they do not have a telephone line, information is collected as to the reasons why. Information is also collected on the income characteristics of the selected households.
The management of the survey was transferred from Stentor to Bell Canada in the Fall of 1998.
The Labour Force Survey (LFS) supplementary capacity is used to conduct this biannual survey. A sample of approximately 44,000 respondents is used for this survey (five out of six rotation groups). The survey data are collected using Computer Assisted Interviewing (CAI). The first data collection procedure took place during November's LFS week in 1996.
This microdata file is prepared biannually and contains the variables from the survey, plus geographical variables from the LFS (province, census metropolitan area, urban/rural breakdown). No other variables from the LFS are added to the file.

4. Adult Education and Training Survey, Documentation and Data Files Archived
Public use microdata: 81M0013X
Description:
The Adult Education and Training Survey (AETS) is Canada's most comprehensive source of data on individual participation in formal adult education and training. It is the only Canadian survey to collect detailed information about the skill development efforts of the entire adult Canadian population. The AETS provides information about the main subject of training activities, their provider, duration and the sources and types of support for training. Furthermore, the AETS allows for the examination of the socio-economic and demographic profiles of both training participants and non-participants. This survey also identifies barriers faced by individuals who wish to take some form of training but cannot. The AETS was administered three times during the 1990s, in 1992, 1994 and 1998, as a supplement to the Labour Force Survey (LFS).
The content of the AETS was revised to take into account recommendations coming from consultation exercises. As a result, more than half of the 2003 survey is made up of new questions and the target population has been modified.
The main objectives are:1) To measure the incidence and intensity of adults' participation in job-related formal training.2) To profile employer support to job-related formal training.3) To analyze the aspects of job-related training activities such as: training provider, expenses, financial support, motivations, outcomes and difficulties experienced while training.4) To identify the barriers preventing individuals from participating in the job-related formal training they want or need to take.5) To identify reasons explaining adults' lack of participation and of interest in job-related formal training.6) To relate adults' current participation patterns to their past involvement in and plans about future participation in job-related training.7) To measure the incidence and frequency of adults' participation in job-related informal training.8) To examine the interactions between participation in formal and informal job-related training.
The population covered by the AETS consists of Canadians 25 years of age and older. This is a change from the population previously targeted by the AETS, which consisted of Canadians aged 17 years of age and older. A primary consideration for this change was the practical difficulties in applying the definition of adult education to individuals in the 17 to 24 years of age group. By definition, adult education excludes students who are still involved in their first or initial stage of schooling. As previous AETS did not precisely identify students still in their initial stage of schooling, analyses using these data had to rely on an ad hoc definition of adult learners. According to this definition, individuals aged 17 to 24 who were not in one of the following situations were excluded from the analysis: full-time students subsidized by an employer and full-time students over 19 enrolled in elementary or secondary programs.

81. Collecting vehicle use data: the Canadian Vehicle Survey experience Archived
Articles and reports: 11-522-X20010016260
Description:
This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
The Canadian Vehicle Survey (CVS), which began in 1999, is designed to collect information about the usage of motor vehicles registered in Canada. The CVS target population includes all on-road vehicles (except special equipment, trailers and motorcycles) registered in Canada. A sample of vehicles is drawn each quarter and a seven-day trip log is used to gather detailed vehicle usage patterns. The log includes questions on kilometres driven, number of passengers, vehicle characteristics, trip purpose and travel times, driver and passenger demographics and fuel usage. Since this is a voluntary survey and the log takes seven days to complete, every effort is made to ensure a good response rate and prevent response errors. The first part of this paper describes the current survey design, data collection, and editing and imputation methodology. Then it goes on to explain the challenges associated with the different steps of the survey. Finally, findings from the research carried out to minimize the effects of non-sampling errors are presented.

Articles and reports: 11-522-X20010016275
Description:
This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
Hot deck imputation, in which missing items are replaced with values from respondents, is often used in survey sampling. A model supporting such procedures is the model in which response probabilities are assumed equal within imputation cells. In this paper, an efficient version of hot deck imputation is described, as are the variance of the efficient version derived under the cell response model and an approximation to the fully efficient procedure in which a small number of values are imputed for each non-respondent, respectively. Variance estimation procedures are presented and illustrated in a Monte Carlo study.

85. Changes in the Diversification of Canadian Manufacturing Firms and Plants (1973-1997): A Move to Specialization Archived
Articles and reports: 11F0019M2002179
Geography: Canada
Description:
This paper studies changes in diversification of firms and plants since the early 1970s in the Canadian manufacturing sector. It finds that there has been a general increase in specialization of both firms and plants. Firms have been continuously reducing the span of industries in which they operate, particularly when the industries are unrelated. Commodity specialization has also occurred at the plant level; however, in contrast to industry specialization, the pace of commodity specialization increased emerged late in the period, around the time of implementation of the Free Trade Agreement between Canada and the United States. Plant specialization increased most in those plants that moved most strongly into export markets.

86. Dynamics of the Canadian Manufacturing Sector in Metropolitan and Rural Regions Archived
Articles and reports: 11F0019M2001169
Geography: Canada
Description:
This paper documents the changing geography of the Canadian manufacturing sector over a twenty-two year period (1976-1997). It does so by looking at the shifts in employment, as well as other measures of industrial change, across different levels of the rural/urban hierarchy - central cities, adjacent suburbs, medium and small cities, and rural areas.
The analysis demonstrates that the most dramatic shifts in manufacturing employment were from the central cities of large metropolitan regions to their suburbs. Paralleling trends in the United States, rural regions of Canada have increased their share of manufacturing employment. Rising rural employment shares were due to declining employment shares of small cities and, to lesser degree, large urban regions. Increasing rural employment was particularly prominent in Quebec, where employment shifted away from the Montreal region. By way of contrast, Ontario's rural regions only maintained their share of employment and the Toronto region increased its share of provincial employment over the period. The changing fortunes of rural and urban areas was not the result of across-the-board shifts in manufacturing employment, but was the net outcome of differing locational patterns across industries.
Change across the rural/urban hierarchy is also measured in terms of wage and productivity levels, diversity, and volatility. In contrast to the United States, wages and productivity in Canada do not consistently decline moving down the rural/urban hierarchy from the largest cities to the most rural parts of the country. Only after controlling for the types of manufacturing industries found in rural and urban regions is it apparent that wages and productivity decline with the size of place. The analysis also demonstrates that over time most rural and urban regions are diversifying across a wider variety of manufacturing industries and that shifts in employment shares across industries - a measure of economic instability - has for some rural/urban classifications increased modestly.

87. School Performance of the Children of Immigrants in Canada, 1994-98 Archived
Articles and reports: 11F0019M2001178
Geography: Canada
Description:
The school performance of the children of immigrants in the Canadian school system is analyzed using data from the first three waves of the National Longitudinal Survey of Children and Youth (NLSCY). School performance is measured in terms of ability at reading, writing, mathematics and overall aptitude. The parents' and teachers' assessments of the children's performances are used, as are the results of formal testing. On average, children of immigrants generally do at least as well as the children of the Canadian-born along each dimension of school performance. The children of immigrant parents whose first language is either English or French have especially high outcomes. The children of other immigrant parents have lower performance in reading, writing and composition but their performance in mathematics is comparable to that of the children of Canadian-born parents. It is also found that with more years in the Canadian education system, the performance of these children in reading, writing and mathematics improves and is equal to or greater than the performance of the children of Canadian-born parents by age thirteen in virtually all areas of performance.

88. The Effects of Inter-provincial Mobility on Individuals' Earnings: Panel Model Estimates for Canada Archived
Articles and reports: 11F0019M2001163
Geography: Canada
Description:
This paper presents the findings of an empirical investigation of the effects of inter-provincial migration on individuals' earnings based on the newly available Longitudinal Administrative Database (LAD). The main results are based on a difference model which estimates the effects of mobility on (log) earnings which implicitly controls for initial earnings levels and other fixed effects, as well as other influences captured by the regressors included in the models. Inter-provincial mobility is found to be associated with statistically significant and in many cases quantitatively substantial changes in individuals' earnings, with these effects varying by age, sex, and province of origin. Pre- and post-move earnings profiles are also analysed, offering support for the validity of the difference model approach and indicating that movers are quickly integrated into local labour markets after their moves. Implications are discussed and possible directions for future research are suggested.

89. An Assessment of EI and SA Reporting in SLID Archived
Articles and reports: 11F0019M2001166
Geography: Canada
Description:
This study assesses two potential problems with respect to the reporting of Employment Insurance (EI) and Social Assistance (SA) benefits in the Survey of Labour and Income Dynamics (SLID): (a) under-reporting of the monthly number of beneficiaries; and (b) a tendency to incorrectly report receiving benefits throughout the year, while in fact benefits may have been received only in certain months, leading to artificial spikes in the January starts and December terminations of benefit spells (seam effect). The results of the analysis show the following:
(1) The rate of under-reporting of EI in SLID is about 15%. Although it varies by month (from 0% to 30%), it is fairly stable from year to year.
(2) There are significant spikes in the number of January starts and December terminations of EI benefit spells. However, the spikes in January starts appear to represent a real phenomenon, rather than a seam problem. They mirror closely the pattern of establishment of new EI claims (the latter increase significantly in January as a result of the decline in employment following the Christmas peak demand). There are no corresponding statistics for EI claim terminations to assess the nature of December spikes.
(3) The rate of under-reporting of SA in SLID is about 50%, significantly greater than for EI. The rate of under-reporting goes down to about 20% to 30%, if we assume that those who received SA, but did not report in which months they received benefits, received benefits throughout the year.
(4) There are large spikes in the number of January starts and December terminations. As in the case of EI, the SA could reflect a real phenomenon. After all, SA starts and terminations are affected by labour market conditions, in the same way EI starts and terminations are affected. However, the SA spikes are much larger than the EI spikes, which increases the probability that, at least in part, are due to a seam effect.

11. Evaluation of the Strengths and Difficulties Questionnaire Archived
Surveys and statistical programs – Documentation: 89-634-X2009008
Geography: Canada
Description:
The Strengths and Difficulties Questionnaire (SDQ) is a parent-reported instrument designed to provide information on children's behaviours and relationships. The SDQ consists of 25 items which are grouped into five subscales: (1) pro-social, (2) inattention-hyperactivity, (3) emotional symptoms, (4) conduct problems, and (5) peer problems. The SDQ was used to provide information on children aged 2 to 5 years in the 2006 Aboriginal Children's Survey (ACS). Though validated on general populations, the constructs of the SDQ have not been validated for off-reserve First Nations, Métis and Inuit children in Canada. The first objective of this evaluation is to examine if the five subscales of the SDQ demonstrate construct validity and reliability for off-reserve First Nations, Métis and Inuit children. The second objective is to examine if an alternative set of subscales, using the 25 SDQ items, may be more valid and reliable for off-reserve First Nations, Métis and Inuit children.

12. Feasibility Study on the Use of Provincial/Territorial Medicare Records for Measuring the Level of Inter-provincial and Inter-territorial Migration Archived
Surveys and statistical programs – Documentation: 91F0015M2008010
Geography: Canada
Description:
The objective of this study is to examine the feasibility of using provincial and territorial health care files of new registrants as an independent measure of preliminary inter-provincial and inter-territorial migration. The study aims at measuring the conceptual and quantifiable differences between this data source and our present source of the Canada Revenue Agency's Canadian Child Tax Benefit.
Criteria were established to assess the quality and appropriateness of these provincial/territorial health care records as a proxy for our migration estimates: coverage, consistency, timeliness, reliability, level of detail, uniformity and accuracy.
Based on the present analysis, the paper finds that these data do not ameliorate the estimates and would not be suitable at this time as a measure of inter-provincial/territorial migration. These Medicare data though are an important independent data source that can be used for quality evaluation.

Description:
This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.
In surveys with low response rates, non-response bias can be a major concern. While it is not always possible to measure the actual bias due to non-response, there are different approaches that help identify potential sources of non-response bias. In the National Center for Education Statistics (NCES), surveys with a response rate lower than 70% must conduct a non-response bias analysis. This paper discusses the different approaches to non-response bias analyses using examples from NCES.

17. Combining administrative data with survey data: experience in the Australian survey of employment and unemployment patterns Archived
Surveys and statistical programs – Documentation: 11-522-X19990015644
Description:
One method of enriching survey data is to supplement information collected directly from the respondent with that obtained from administrative systems. The aims of such a practice include being able to collect data which might not otherwise be possible, provision of better quality information for data items which respondents may not be able to report accurately (or not at all) reduction of respondent load, and maximising the utility of information held in administrative systems. Given the direct link with administrative information, the data set resulting from such techniques is potentially a powerful basis for policy-relevant analysis and evaluation. However, the processes involved in effectively combining data from different sources raise a number of challenges which need to be addressed by the parties involved. These include issues associated with privacy, data linking, data quality, estimation, and dissemination.

18. Weighting and variance estimation for the exploration of possible time trends in data from the U.S. Third National Health and Nutrition Examination Survey Archived
Surveys and statistical programs – Documentation: 11-522-X19980015031
Description:
The U.S. Third National Health and Nutrition Examination Survey (NHANES III) was carried out from 1988 to 1994. This survey was intended primarily to provide estimates of cross-sectional parameters believed to be approximately constant over the six-year data collection period. However, for some variable (e.g., serum lead, body mass index and smoking behavior), substantive considerations suggest the possible presence of nontrivial changes in level between 1988 and 1994. For these variables, NHANES III is potentially a valuable source of time-change information, compared to other studies involving more restricted populations and samples. Exploration of possible change over time is complicated by two issues. First, there was of practical concern because some variables displayed substantial regional differences in level. This was of practical concern because some variables displayed substantial regional differences in level. Second, nontrivial changes in level over time can lead to nontrivial biases in some customary NHANES III variance estimators. This paper considers these two problems and discusses some related implications for statistical policy.
