This article examines the extent of proxy reporting in the Natiional Population Health (NPHS). It also explores associations between proxy reporting status and the prevalence of selected health problems, and investigates the relationship between changes in proxy reporting status and two-year incidence of health problems.

This article examines associations between selected work- and non-work-related factors and the incidence of chronic back problems over the next two years.

This article examines changes in household spending on health care between 1978 and 1998. It also provides a detailed look at household spending on health care in 1998.

This study aims to help tourism destinations planners understand the characteristics of domestic bird and wildlife viewing markets so that they may be better prepared to meet the demands of these groups of travellers.

The Vancouver-San Francisco market experienced the largest year-over-year increase in passengers of all the major markets between 1997 and 1998. Toronto-Milwaukee was the mid-sized market which experienced the largest year-over-year increase, with 25,520 more passengers in 1998 than 1997.

The volume of air travel between the Canadian cities and American states presented in Text Table 2.1 generally reflects the underlying large inter-city markets.

The Canada-United States Open Skies Agreement, which was signed on February 24 1995, transformed the regulatory environment for air services between two countries. Text Table 3.1 shows the changes in the level of travel between the U.S. and the eight most-frequented Canadian cities since 1995.

Scheduled air trips to or from Ontario, British Columbia and Alberta represented a greater proportion of total Canada-United States air travel than residents of these provinces represented of the total Canadian population. Alberta residents represented 9.6% of Canada's total population in 1998, while Alberta represented 11.8% of the total number of Canada-U.S. air travellers. Even more markedly, the populations of Ontario and British Columbia represented 37.7% and 13.2% respectively of the total Canadian population, while Ontario represented 44.4% of total Canada-U.S. travelers and British Columbia represented 20.8%.

In this paper, we will estimate the number of Canadian passengers that are going to "business" and "leisure" markets and whether these passengers have seen an improvement in service since the signing of the Open Skies Agreement.

The most recent police-reported statistics indicate that the crime rate in Canada has decreased for the eighth consecutive year and is at its lowest point since 1979. Statistics from the United States and from many other countries show similar trends. However, data from studies such as the 1993 General Social Survey (GSS), the 1996 International Criminal Victimization Survey (ICVS), and national polls suggest that many Canadians perceive crime as increasing and fear being a victim of crime in their neighbourhoods. The most feared crimes are those of a violent nature, especially homicide – the killing of one human being by another – which tends to receive more media attention than any other criminal act. Despite this concern among Canadians about violence, the homicide rate has been declining since the mid-1970s.

The third edition of Canadian culture in perspective: a statistical overview, provides a comprehensive statistical portrait of the health and vitality of cultural activities and industries in Canada. This compendium incorporates data from all surveys in Statistics Canada's Culture Statistics Program, as well as data from other internal and external sources, enabling readers to track various themes and trends over time.

This edition contains sections on: the economic impact of the culture sector, culture activities by tourists and the international trade position of the culture sector; on social dimensions of culture, including characteristics of the cultural labour force, philanthropic behaviour, and the consumers of cultural goods and services; and on various sectors such as heritage, the performing arts and festivals, visual arts and libraries. It also explores ownership and content issues in the culture industries (publishing, film, broadcasting and music).

Canada's ports handled a record 382.0 million tonnes (Mt.) of cargo in 1999 and a record of 2.2 million TEURS (twenty-foot-equivalent units) of containers.

Third quarter 1999 operating ratios for top carriers improved by one point over the same period one year earlier to 0.93 but were unchanged in the fourth quarter (0.94). Average revenue per carrier grew by 3% in the third quarter and 4% in the fourth quarter.

Retirement issues have risen to the forefront of socio-economic debate in Canada through the nineties and will likely gain importance as we enter the new millennium. Employer pension plans are one of the primary programs in place to provide workers with income after retirement.

Pension plans in Canada: statistical highlights and key tables presents information on the terms, conditions and membership on all employers sponsored pension plans in Canada. This supplement to publication Pension plans in Canada (74-401-XIB) provides analysis and data on registered pension plans. The topics covered include province of employment, labour force/paid workers coverage, type of plan (defined benefit and defined contributions), size of plan, public and private sectors, contributory and non-contributory plans, employee and employer contributions.

This publication presents current and constant price estimates of provincial gross domestic product (GDP) for over 50 industries covering the entire Canadian economy, including aggregates and special industry groupings. The document also includes a comprehensive analytical review of the economy of each province and territory with summary text, tables and charts.

Samples from hidden and hard-to-access human populations are often obtained by procedures in which social links are followed from one respondent to another. Inference from the sample to the larger population of interest can be affected by the link-tracing design and the type of data it produces. The population with its social network structure can be modeled as a stochastic graph with a joint distribution of node values representing characteristics of individuals and arc indicators representing social relationships between individuals.

To better understand the impact of imposing a restricted region on calibration weights, the author reviews the latter's aymptotic behaviour. Necessary and sufficient conditions are provided for the existence of a solution to the calibration equation with weights within given intervals.

For surveys which involve more than one stage of data collection, one method recommended for adjusting weights for nonresponse (after the first stage of data collection) entails utilizing auxiliary variables (from previous stages of data collection) which are identified as predictors of nonresponse.

Survey statisticians frequently use superpopulation linear regression models. The Gauss-Markov theorem, assuming fixed regressors or conditioning on observed values of regressors, asserts that the standard estimators of regression coefficients are best linear unbiased.

This report examines the factors contributing to the rapid growth of a small number of biotechnology firms in Canada.

This is the second release of preliminary data in advance of the annual publication, scheduled for completion in October of this year. It covers facilities-based carriers (wireline, wireless and satellite) as well as resellers.

This Juristat from the Canadian Centre for Justice Statistics analyzes recent trends in the sentencing of young offenders, those aged 12 to 17, who have been convicted of a federal offence. The analysis is based on data released earlier in May of this year.

It provides information on the characteristics of young offenders sentenced in court, the nature of dispositions, trends in sentencing, and comparisons of young offenders on the basis of age, sex, nature of charge, number of charges and prior convictions. In addition, this report compares the sentencing of adult and young offenders.

The purpose of this Juristat is to provide information on the administration of alternative measures in Canada, and its relative success in diverting individuals out of the court system. The report focuses on alternative measures for youth, but also includes a short section presenting data on adult alternative measures.

The incomes of culture workers have long been an issue of concern to culture organizations and lobby groups. Using the 1997 Census, we can look at the average earnings of some 500 different occupations including some selected culture occupations.

When productivity increases in a sector, does it mean employment growth? This article explores the question and introduces a new concept: multifactor productivity.

This paper states how SN is preparing for a new era in the making of statistics, as it is triggered by technological and methodological developments. An essential feature of the turn to the new era is the farewell to the stovepipe way of data processing. The paper discusses how new technological and methodological tools will affect processes and their organization. Special emphasis is put on one of the major chances and challenges the new tools offer: establishing coherence in the content of statistics and in the presentation to users.

The Longitudinal Immigration Database (IMDB) links immigration and taxation administrative records into a comprehensive source of data on the labour market behaviour of the landed immigrant population in Canada. It covers the period 1980 to 1995 and will be updated annually starting with the 1996 tax year in 1999. Statistics Canada manages the database on behalf of a federal-provincial consortium led by Citizenship and Immigration Canada. The IMDB was created specifically to respond to the need for detailed and reliable data on the performance and impact of immigration policies and programs. It is the only source of data at Statistics Canada that provides a direct link between immigration policy levers and the economic performance of immigrants. The paper will examine the issues related to the development of a longitudinal database combining administrative records to support policy-relevant research and analysis. Discussion will focus specifically on the methodological, conceptual, analytical and privacy issues involved in the creation and ongoing development of this database. The paper will also touch briefly on research findings, which illustrate the policy outcome links the IMDB allows policy-makers to investigate.

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.

We estimate the parameters of a stochastic model for labour force careers involving distributions of correlated durations employed, unemployed (with and without job search) and not in the labour force. If the model is to account for sub-annual labour force patterns as well as advancement towards retirement, then no single data source is adequate to inform it. However, it is possible to build up an approximation from a number of different sources.

The U.S. Manufacturing Plant Ownership Change Database (OCD) was constructed using plant-level data taken from the Census Bureau's Longitudinal Research Database (LRD). It contains data on all manufacturing plants that have experienced ownership change at least once during the period 1963-92. This paper reports the status of the OCD and discuss its research possibilities. For an empirical demonstration, data taken from the database are used to study the effects of ownership changes on plant closure.

Objective: To create an occupational surveillance system by collecting, linking, evaluating and disseminating data relating to occupation and mortality with the ultimate aim of reducing or preventing excess risk among workers and the general population.

Time series studies have shown associations between air pollution concentrations and morbidity and mortality. These studies have largely been conducted within single cities, and with varying methods. Critics of these studies have questioned the validity of the data sets used and the statistical techniques applied to them; the critics have noted inconsistencies in findings among studies and even in independent re-analyses of data from the same city. In this paper we review some of the statistical methods used to analyze a subset of a national data base of air pollution, mortality and weather assembled during the National Morbidity and Mortality Air Pollution Study (NMMAPS).

Radon, a naturally occurring gas found at some level in most homes, is an established risk factor for human lung cancer. The U.S. National Research Council (1999) has recently completed a comprehensive evaluation of the health risks of residential exposure to radon, and developed models for projecting radon lung cancer risks in the general population. This analysis suggests that radon may play a role in the etiology of 10-15% of all lung cancer cases in the United States, although these estimates are subject to considerable uncertainty. In this article, we present a partial analysis of uncertainty and variability in estimates of lung cancer risk due to residential exposure to radon in the United States using a general framework for the analysis of uncertainty and variability that we have developed previously. Specifically, we focus on estimates of the age-specific excess relative risk (ERR) and lifetime relative risk (LRR), both of which vary substantially among individuals.

There are many different situations in which one or more files need to be linked. With one file the purpose of the linkage would be to locate duplicates within the file. When there are two files, the linkage is done to identify the units that are the same on both files and thus create matched pairs. Often records that need to be linked do not have a unique identifier. Hierarchical record linkage, probabilistic record linkage and statistical matching are three methods that can be used when there is no unique identifier on the files that need to be linked. We describe the major differences between the methods. We consider how to choose variables to link, how to prepare files for linkage and how the links are identified. As well, we review tips and tricks used when linking files. Two examples, the probabilistic record linkage used in the reverse record check and the hierarchical record linkage of the Business Number (BN) master file to the Statistical Universe File (SUF) of unincorporated tax filers (T1) will be illustrated.

As the availability of both health utilization and outcome information becomes increasingly important to health care researchers and policy makers, the ability to link person-specific health data becomes a critical objective. This type of linkage of population-based administrative health databases has been realized in British Columbia. The database was created by constructing an historical file of all persons registered with the health care system, and then by probabilistically linking various program files to this 'coordinating' file. The first phase of development included the linkage of hospital discharge data, physician billing data, continuing care data, data about drug costs for the elderly, births data and deaths data. The second phase of development has seen the addition data sources external to the Ministry of Health including cancer incidence data, workers' compensation data, and income assistance data.
