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).

It also presents commodity detail by province on inputs and outputs and estimates of total forest production, by products and by province. A data analysis, definitions and notes, a bibliography and a list of establishments by province are also included.

Montreal-Toronto was the top domestic market in 1998 for passengers on scheduled flights, followed by the Toronto-Vancouver market. Toronto-Vancouver was the top market for passengers on charter flights, followed by the Montreal-Toronto market.

Text Table 2.1 shows the change in the relationship between passenger counts and population for the ten most-frequented Canadian cities over the years 1973, 1993 and 1998.

Text Table 3.1 shows the relationship between passengers and population for each province and territory. In this table, passengers are assigned to each province/territory based on the ticket origin.

In this paper, the proportion of passengers flying within Canada that reach their destination on a direct flight is measured in order to assess the service that is offered by the carriers.

This on-line publication presents statistics and analysis on the volume of domestic air passenger traffic generated at Canadian cities and carried between pairs of Canadian points. The data may be used to indicate the relative community of interest between Canadian cities.

Revenues of private television broadcasters reached $1,862.9 in 1999, an increase of 2.2% from 1998. This increase is modest when compared to the two previous years where revenues grew 7.0% and 6.3% respectively. There was very little change in the relative importance of sources of revenues; the sale of air time accounted for 94.1% of revenues compared to 94.6% a year earlier.

Revenues of private radio broadcasters reached $971.9 million in 1999, an increase of 3.2% from 1998. This increase is modest when compared to the two previous years where revenues rose 8.1% and 7.5% respectively.

Data on furniture and fixture industries clearly show the tremendous expansion period affecting these industries. Several establishments have taken advantage of the favourable economic conditions and the openness of North American markets to increase their deliveries to the United States. Foreign markets have been the driving force behind the furniture and fixture industries' growth in the past decade, since large establishments generally have more resources to break into these markets.

Richard Platek, the founding Chairman, who remained at the helm of the Journal until 1987, has provided an excellent overview of the gradual evolution of the Journal from a modest divisional to a respected departmental publication and then to an international publication of repute.

Dr. Fellegi considers the challenges facing government statistical agencies and strategies to prepare for these challenges. He first describes the environment of changing information needs and the social, economic and technological developments driving this change. He goes on to describe both internal and external elements of a strategy to meet these evolving needs. Internally, a flexible capacity for survey taking and information gathering must be developed. Externally, contacts must be developed to ensure continuing relevance of statistical programs while maintaining non-political objectivity.

Leslie Kish describes the challenges and opportunities of combining data from surveys of different populations. Examples include multinational surveys where the data from surveys of several countries are combined for comparison and analysis, as well as cumulated periodic surveys of the "same" population. He also compares and contrasts the combining of surveys with the combining of experiments.

In 1999 Statistics Sweden outlined a proposal for improved quality within the European Statistical System (ESS). The ESS comprises Eurostat and National Statistical Institutes (NSIs) associated with Eurostat. ... Basically Statistics Sweden proposed the creation of a LEG [Leadership Expert Group] on Quality].

In his paper Fritz Scheuren considers the possible uses of administrative records to enhance and improve population censuses. After reviewing previous uses of administrative records in an international context, he puts forward several proposals for research and development towards increased use of administrative records in the American statistical system.

Godambe and Thompson consider the problem of confidence intervals in survey sampling. They first review the use of estimating functions to obtain model robust pivotal quantities and associated confidence intervals, and then discuss the adaptation of this approach to the survey sampling context. Details are worked out for some more specific types of models, and an empirical comparison of this approach with more conventional methods is presented.

J.N.K. Rao gives an overview of the methods and models used for small area estimation. This is an update of his previous overview (Ghosh and Rao, 1994, Statistical Science). He first presents a general discussion of small area models, making a distinction between area level models and unit level models. He then describes the development in three main approaches for inference based on these models: EBLUP, EB and HB, gives several examples of recent applications. Finally, he presents an interesting discussion identifying the gaps and areas that require further research.

Sirken and Shimizu derive a Horvitz-Thompson estimator for population based establishment sample surveys (PBESs). A PBES is a survey of establishments where the sampling frame consists of establishments with which a preliminary sample of households or individuals has had some contact.

Jean-Claude Deville shows how to use simple tools to calculate the variance of a complex estimator using a linearization technique. The process is that of a software used at INSEE for estimation of the variance of a complex estimator. It gives a way of computing the variance of a total estimated by the simple expansion estimator. In the case of a complex statistic, the process uses a derived variable that reduces the computations to those of the simple expansion estimator. Multiple examples are given to illustrate the process.

Brewer proposes a method of weight calibration in survey sampling, called cosmetic calibration, which yields cosmetic estimators of totals, i.e. estimators that can be interpreted as both design-based and prediction based. He also discusses variance estimation and shows how the problem of negative weights can be easily and naturally handled using cosmetic calibration. Finally he compares the properties of the weights and the resulting estimators to some alternative approaches using some Australian far data.

This guide presents information of interest to users of data from the Survey of Household Spending. Data are collected via personal interviews conducted in January, February and March after the reference year using a paper questionnaire. Information is gathered about the spending habits, dwelling characteristics and household equipment of Canadian households during the reference year. The survey covers private households in the ten provinces and three territories. (The three territories are surveyed every second year.)

This guide includes definitions of survey terms and variables and descriptions of survey methodology and data quality. There is also a section describing the various statistics that can be created using expenditure data (e.g., budget share, market share, and aggregates).

This report provides an overview of an inventory of publicly available data on the nonprofit sector.

Direct measures of skill attainment such as the International Adult Literacy Survey are used to assess the importance of educational outcome skills such as literacy in determining labour market outcomes such as earnings. Policy makers also use them to direct resources most efficiently. However, these skill measures are the product of complex statistical procedures. This paper examines the mathematical robustness of the International Adult Literacy Survey measures against other possibilities in estimating the impact of literacy on individual earnings.

With the release of the first quarter 2000 of the National Income and Expenditure Accounts the sectoring of federal and provincial government, non-autonomous pension plans has changed. These pension plans are now part of the personal sector. Previously these plans were included in either the federal or provincial government sector accounts.

The Cancer Record is a newsletter for cancer registries in Canada. Its main purpose is to improve the quality and consistency of data submitted to the Canadian Cancer Registry. The goals of the newsletter are to establish and continue communication among cancer registry personnel, establish a mechanism for identifying and resolving coding or reporting inconsistencies in the national registry and update cancer registries regarding the continued development at the national level.

This paper deals with a problem in internationally comparable economic statistics, namely, the fact that countries measure value added by industry differently. The economic measure, value added, is important both in its own right and because it is a component of other economic measures such as productivity. Value added by industry measures the additional value created by a production process. This additional value, created by factors of production such as labour and capital, may be calculated either before or after deducting the consumption of fixed capital used in production. Thus, gross value added by industry is the value of its output of goods and services less the value of its intermediate consumption of goods and services and net value added as the value of output less the values of both intermediate consumption and consumption of fixed capital.

The intent of this document is to provide an inventory of the surveys, databases, publications, articles and work in progress in Statistics Canada that relate to Canada's retirement income programs. The inventory provides information on publications, output and relevant data elements produced by the surveys and databases. It does not provide an exhaustive description of these data sources, but instead focuses on the information that can be used for purposes of researching/analysing retirement income programs. Some of the information contained does not specifically relate to these programs but might be used as a secondary source when doing research in this area.

The focus of Symposium'99 is on techniques and methods for combining data from different sources and on analysis of the resulting data sets. In this talk we illustrate the usefulness of taking such an "integrating" approach when tackling a complex statistical problem. The problem itself is easily described - it is how to approximate, as closely as possible, a "perfect census", and in particular, how to obtain census counts that are "free" of underenumeration. Typically, underenumeration is estimated by carrying out a post enumeration survey (PES) following the census. In the UK in 1991 the PEF failed to identify the full size of the underenumeration and so demographic methods were used to estimate the extent of the undercount. The problems with the "traditional" PES approach in 1991 resulted in a joint research project between the Office for National Statistics and the Department of Social Statistics at the University of Southampton aimed at developing a methodology which will allow a "One Number Census" in the UK in 2001. That is, underenumeration will be accounted for not just at high levels of aggregation, but right down to the lowest levels at which census tabulations are produced. In this way all census outputs will be internally consistent, adding to the national population estimates. The basis of this methodology is the integration of information from a number of data sources in order to achieve this "One Number".
