The purpose of this report is to provide an overview of existing methods and techniques making use of personal identifiers to support record linkage. Record linkage can be loosely defined as a methodology for manipulating and / or transforming personal identifiers from individual data records from one or more operational databases and subsequently attempting to match these personal identifiers to create a composite record about an individual. Record linkage is not intended to uniquely identify individuals for operational purposes; however, it does provide probabilistic matches of varying degrees of reliability for use in statistical reporting. Techniques employed in record linkage may also be of use for investigative purposes to help narrow the field of search against existing databases when some form of personal identification information exists.

In 1999, as part of its General Social Survey program, Statistics Canada conducted a survey on victimization and public perceptions of crime and the justice system. It was the third time that the General Social Survey (GSS) had examined victimization - previous surveys were conducted in 1993 and 1988.

For the 1999 survey, interviews were conducted by telephone with approximately 26,000 people, aged 15 and older, living in the 10 provinces. Respondents were asked for their opinions concerning the level of crime in their neighbourhood, their fear of crime and their views concerning the performance of the justice system. They were also asked about their attitudes toward sentencing adult and young offenders. Respondents were randomly presented with one of four hypothetical situations for which they were asked to choose "prison" or "non-prison". Respondents who selected prison sentences were given a follow-up question that asked them whether a sentence of one year of probation and 200 hours of community work was an acceptable alternative to the prison sentence.

This Juristat examines public attitudes toward sentencing adult and young offenders. It also analyzes public attitudes toward four sectors of the justice system including, the police, the criminal courts, the prison and parole systems.

This article examines whether the education levels of graduates surpass the needs of employers, and to what extent.

This article provides an analysis of the employment and earnings patterns of recent postsecondary graduates, based on three waves of the National Graduates Surveys.

This Juristat outlines the characteristics of criminal harassment incidents as well as the characteristics of the accused and victim for 1999, and identifies trends over the past five years. (Trend data are only available for the five-year period from 1995 to 1999.) This Juristat updates a similar Juristat written in 1996 using information collected from police forces and adult criminal courts to review the charges laid and sentences imposed for cases involving criminal harassment.

There are many different types of stalkers. However, most victims of criminal harassment know their accused quite well and, in many instances, the stalker and victim were involved in a previous relationship.

Statistics Canada publishes several measures of farm income, each produced for a different purpose. This bulletin describes the concepts behind these different measures, the methods by which the measures are constructed, and the uses for which they were designed.

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.

This study looks at those who voluntarily work part time, as well as their reasons for doing so, their levels of work-related stress, and their job characteristics.

This Bulletin provides recent information on the performance and funding of Federal Government Expenditures on Scientific Activities, 2000-2001. The statistics presented are derived from the survey of the science and technology (S&T) activities of Federal departments and agencies. According to international convention, S&T is divided into two fields; Natural Sciences and Engineering (NSE) and Social Sciences and Humanities (SSH). These fields of science are further divided into Research and Development (R&D) and Related Scientific Activities (RSA).

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 the first part of this study, we will explore the development of the ski industry in Canada, after taking a short historical detour. In part two we will examine the characteristics of American travellers who visited Canadian ski areas (to ski or snowboard) during an overnight stay in Canada in the winter of 1998-99. Lastly, we will take a quick look at some characteristics of the overseas skier/snowboarder and at their contribution to the Canadian economy.

This article focuses on characteristics of primary Internet service providers (ISPs), that is, firms reporting that 50% or more of their revenues come from ISP activities. It looks at challenges facing ISPs including barriers to growth, competing in the Internet sector, complaints and practices regarding offensive content and conduct, as well as ISPs' perceptions of what is important to their customers. These items are analysed after classifying ISPs into four different size categories, enabling one to see any differences in perception or conduct between ISPs of varying sizes.

The latest issue consists of the article "Wood manufacturers have been stimulated by the strength of the domestic market" by Gilles Simard. The effects of the decrease in interest rates in Canada in 1996 were felt fully in 1997. The increased activity in housing development in Canada, and to a lesser extent, in the United States, has stimulated the wood industry. However, the crisis in Asia during the summer of 1997 was a heavy blow to British Columbia, the province that provides half of Canada's lumber. This article, based on the results of the 1997 Annual Survey of Manufactures (ASM), briefly describes changes in the industry in 1997 and 1998 and looks at recent events in.

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.
