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.

Reduced barriers to trade across North America and increasingly mobile populations have created a heightened need for information on transportation services and infrastructure. North American transportation highlights provides key summary statistics on trade and travel, safety, and energy use of transportation in Mexico, the United States and Canada. Statistical tables and charts contained within the report are accompanied by data sources and notes describing data categories and definitions relating to each country.

The report was developed under the framework of the North American Transportation Statistics Interchange representing the transportation and statistical agencies of Mexico, the United States and Canada. Participating agencies include the Secretaría de Comunicaciones y Transportes, the Instituto Mexicano del Transporte, and the Instituto Nacional de Estadística Geografía e Informática from México; the Bureau of Transportation Statistics and the Census Bureau from the United States; Statistics Canada and Transport Canada. It was produced and released by the U.S. Bureau of Transportation Statistics (BTS) in December 1999 and is part of more comprehensive report, North American transportation in figures (catalogue no. 50-501-XIE) released in October 2000.

There is a diversity of manufacturing activity that contributes to Canada's regional economies. The spatial distribution of these activities is far from symmetrical, with most activity being concentrated within the Québec City - Windsor corridor. In 1997, the provinces of Ontario and Québec accounted for approximately 76% of Canada's value of shipments. Using data from the Annual Survey of Manufactures, two maps have been created to highlight the predominant manufacturing activity by census division in 1983 and 1997. Employing advanced mapping software, it is possible to accurately make maps which show the correspondence between manufacturing activity and the ecumene. The brief discussion herein will help readers to interpret the enclosed maps.

The Manufacturing, Construction and Energy Division is engaged in finding alternatives to presenting data from the Annual Survey of Manufactures using advanced mapping technology. This technology enables us to present a coherent spatial representation of manufacturing activity across Canada. The interactive map presents provincial principle statistics and highlights, with a view to disseminating knowledge and stimulating discussion.

This bulletin is a preliminary release of 1998 annual data for the Cellular Telecommunications Industry (including PCS and ESMR service providers) with accompanying data from 1995.

The most recent issue contains "Food producers maintain expansion" by Peter Zylstra. Food commodity processors are engaged in a multitude of manufacturing activities. The aggregate performance of these is the subject of this article. Common influences on all processing industries that make up the Food Industries Major Group are examined, while specific ones that impact some and not others are also discussed. Growth in food industries has always been a function of population growth. In addition, health considerations and new product development are important factors. The summary of recent developments is based on results of the 1997 Annual Survey of Manufactures. Other sources are also used for industry analysis as well as for the provision of industry environment and economic background.

This article is divided into three sections. Section 1 describes results for small for-hire carriers; section 2 contains data for owner operations; and section 3 provides a general discussion of Annual Motor Carriers of Freight survey data quality.

This study presents 1997/1998 LFS earnings estimates for about 85,000 drivers employed by for-hire carriers (companies whose principal business is transportation of goods for a fee) in comparison to drivers employed in private trucking (companies that transport their freight by truck, but whose principal business activity is not trucking) and the overall labour force. Wages and earnings estimated presented in this study exclude owner operators and self-employed workers.

This publication shows expenditures, by industry, for the various types of packaging materials.

The cable and other program distribution industry has reported revenues of $3.1 billion in 1998, a 10.0% increase over 1997. This relatively strong growth is due in large part to the fast growing non-basic services segment. While revenue from basic services grew moderately (2.1%) revenue from non-basic and other services increased by 29.0%.

This paper looks at the number of business establishment starts in smaller and larger communities in Canada from 1993 to 1996.

In just over a decade, the cellular telephone industry has grown to close to one fifth the size of the traditional teletphone segment of the industry, experiencing an annual revenue growth rate between 22% and 29%. By December 1997, there were just over 4 million cellular telephone subscribers in Canada - a 22% increase over the previous year - more than double the level of subscribers in 1994.

In a recent Statistics Canada survey, 77% of Canadian plant managers felt their production technology was as good as their domestic competitors. Against their U.S. counterparts, they were less confident: only 57% of Canadian firms believed their technologies were as good as their American competitors. The survey also reveals that 70% firms used the Internet and 60% had a "home page" on the World Wide Web.

In 1996, larger financial services companies were the most likely to use the Internet for communications, research and e-commerce. During that year, 73% of banks were using the Internet whereas less than half of the property and casualty insurance companies were connected. E-commerce was undertaken by only 17% of the connected firms whereas 70% was using e-mail and 86% was conducting web searches. Internet users were more innovative and introduced more new products than non-users.

In 1999, the federal government expects to fund 19.4% of the R&D in Canada. Less and less of the government-funded R&D is taking place in government labs. Although overall spending on R&D will increase from $3.5 billion to $4.0 billion, the share of this going to the government research has dropped from 59% to 52%.

You thought it was obvious but the ICT sector that everyone is talking about hasn't had an official definition - until now. We sorted through the SIC (1980) codes and selected 20 that fit. Next issue - the NAICS-based definitions.

Our jobs, communities, leisure activities and patterns of commerce are changing at a dizzying pace - the Internet is literally transforming the way we live, work and play. In 1998, 36% of Canadian households were regular users of computer communication - up sharply from 29% in 1997. And the technology revolution is not over yet!

Gross domestic product expenditures on R&D (GERD) for 1999 increased by 3.5% to $14.9 billion over the previous year. Despite this increase, the proportion of GDP devoted to R&D (1.6%) is still among the lowest of the G-7 countries.

A Statistics Canada study uses business demographics to learn about innovation and technological change and uncovers interesting patterns. Contrary to expectations, the author uncovered considerable volatility (start-ups and closures) in the service sector. The volatility rate for this sector was 31% compared with 23% for the manufacturing sector. Firms that do not innovate frequently are replaced by new ones that have new or improved products to offer or by those that employ more efficient methods of production and delivery.

Some analysts suggest that biotechnology may trigger a revolution equal to the one prompted by information technology. Various sectors of Canadian industry are already actively using biotechnologies for purposes ranging from research and development to pollution control. Many still see obstacles to adopting new biotechnologies including lack of information and government regulation.

Often, the same information is gathered almost simultaneously for several different surveys. In France, this practice is institutionalized for household surveys that have a common set of demographic variables, i.e., employment, residence and income. These variables are important co-factors for the variables of interest in each survey, and if used carefully, can reinforce the estimates derived from each survey. Techniques for calibrating uncertain data can apply naturally in this context. This involves finding the best unbiased estimator in common variables and calibrating each survey based on that estimator. The estimator thus obtained in each survey is always a linear estimator, the weightings of which can be easily explained and the variance can be obtained with no new problems, as can the variance estimate. To supplement the list of regression estimators, this technique can also be seen as a ridge-regression estimator, or as a Bayesian-regression estimator.

The U.S. Consumer Expenditure Survey uses two instruments, a diary and an in-person interview, to collect data on many categories of consumer expenditures. Consequently, it is important to use these data efficiently to estimate mean expenditures and related parameters. Three options are: (1) use only data from the diary source; (2) Use only data from the interview source; and (3) use generalized least squares, or related methods, to combine the diary and interview data. Historically, the U.S. Bureau of Labor Statistics has focused on options (1) and (2) for estimation at the five or six-digit Universal Classification Code level. Evaluation and possible implementation of option (3) depends on several factors, including possible measurement biases in the diary and interview data; the empirical magnitude of these biases, relative to the standard errors of customary mean estimators; and the degree of homogeneity of these biases across strata and periods. This paper reviews some issues related to options (1) through (3); describes a relatively simple generalized least squares method for implementation of option (3); and discussed the need for diagnostics to evaluate the feasibility and relative efficiency of the generalized least squares method.

The geographical and temporal relationship between outdoor air pollution and asthma was examined by linking together data from multiple sources. These included the administrative records of 59 general practices widely dispersed across England and Wales for half a million patients and all their consultations for asthma, supplemented by a socio-economic interview survey. Postcode enabled linkage with: (i) computed local road density; (ii) emission estimates of sulphur dioxide and nitrogen dioxides, (iii) measured/interpolated concentration of black smoke, sulphur dioxide, nitrogen dioxide and other pollutants at practice level. Parallel Poisson time series analysis took into account between-practice variations to examine daily correlations in practices close to air quality monitoring stations. Preliminary analyses show small and generally non-significant geographical associations between consultation rates and pollution markers. The methodological issues relevant to combining such data, and the interpretation of these results will be discussed.

The artificial sample was generated in two steps. The first step, based on a master panel, was a Multiple Correspondence Analysis (MCA) carried out on basic variables. Then, "dummy" individuals were generated randomly using the distribution of each "significant" factor in the analysis. Finally, for each individual, a value was generated for each basic variable most closely linked to one of the previous factors. This method ensured that sets of variables were drawn independently. The second step consisted in grafting some other data bases, based on certain property requirements. A variable was generated to be added on the basis of its estimated distribution, using a generalized linear model for common variables and those already added. The same procedure was then used to graft the other samples. This method was applied to the generation of an artificial sample taken from two surveys. The artificial sample that was generated was validated using sample comparison testing. The results were positive, demonstrating the feasibility of this method.

Electricity rates that vary by time-of-day have the potential to significantly increase economic efficiency in the energy market. A number of utilities have undertaken economic studies of time-of-use rates schemes for their residential customers. This paper uses meta-analysis to examine the impact of time-of-use rates on electricity demand pooling the results of thirty-eight separate programs. There are four key findings. First, very large peak to off-peak price ratios are needed to significantly affect peak demand. Second, summer peak rates are relatively effective compared to winter peak rates. Third, permanent time-or-use rates are relatively effective compared to experimental ones. Fourth, demand charges rival ordinary time-of-use rates in terms of impact.

We use data on 14 populations of coho salmon to estimate critical parameters that are vital for management of fish populations. Parameter estimates from individual data sets are inefficient and can be highly biased, and we investigate methods to overcome these problems. Combination of data sets using nonlinear mixed effects models provides more useful results, however questions of influence and robustness are raised. For comparison, robust estimates are obtained. Model-robustness is also explored using a family of alternative functional forms. Our results allow ready calculation of the limits of exploitation and may help to prevent extinction of fish stocks. Similar methods can be applied in other contexts where parameter estimation is part of a larger decision-making process.
