To augment the amount of available information, data from different sources are increasingly being combined. These databases are often combined using record linkage methods. When there is no unique identifier, a probabilistic linkage is used. In that case, a record on a first file is associated with a probability that is linked to a record on a second file, and then a decision is taken on whether a possible link is a true link or not. This usually requires a non-negligible amount of manual resolution. It might then be legitimate to evaluate if manual resolution can be reduced or even eliminated. This issue is addressed in this paper where one tries to produce an estimate of a total (or a mean) of one population, when using a sample selected from another population linked somehow to the first population. In other words, having two populations linked through probabilistic record linkage, we try to avoid any decision concerning the validity of links and still be able to produce an unbiased estimate for a total of the one of two populations. To achieve this goal, we suggest the use of the Generalised Weight Share Method (GWSM) described by Lavallée (1995).

This paper presents weighting procedures that combine information from multiple panels of a repeated panel household survey for cross-sectional estimation. The dynamic character of a repeated panel survey is discussed in relation to estimation of population parameters at any wave of the survey. A repeated panel survey with overlapping panels is described as a special type of multiple frame survey, with the frames of the panels forming a time sequence. The paper proposes weighting strategies suitable for various multiple panel survey situations. The proposed weighting schemes involve an adjustment of weights in domains of the combined panel sample that represent identical time periods covered by the individual panels. A weight adjustment procedure that deals with changes in the panels over time is discussed. The integration of the various weight adjustments required for cross-sectional estimation in a repeated panel household survey is also discussed.

This article reviews the methods that may be used to produce direct estimates for small areas, including stratification and oversampling, and forms of dual-frame estimation.

In this paper, we discuss the application of the bootstrap with a re-imputation step to capture the imputation variance (Shao and Sitter 1996) in stratified multistage sampling. We propose a modified bootstrap that does not require rescaling so that Shao and Sitter's procedure can be applied to the case where random imputation is applied and the first-stage stratum sample sizes are very small. This provides a unified method that works irrespective of the imputation method (random or nonrandom), the stratum size (small or large), the type of estimator (smooth or nonsmooth), or the type of problem (variance estimation or sampling distribution estimation). In addition, we discuss the proper Monte Carlo approximation to the bootstrap variance, when using re-imputation together with resampling methods. In this setting, more care is needed than is typical. Similar results are obtained for the method of balanced repeated replications, which is often used in surveys and can be viewed as an analytic approximation to the bootstrap. Finally, some simulation results are presented to study finite sample properties and various variance estimators for imputed data.

Local polynomial regression methods are put forward to aid in exploratory data analysis for large-scale surveys. The proposed regression methods are put forward to aid in exploratory data analysis for large-scale surveys. The proposed method relies on binning the data on the x-variable and calculating the appropriate survey estimates for the mean of the y-values at each bin. When binning on x has been carried out to the precision of the recorded data, the method is the same as applying the survey weights to the standard criterion for obtaining local polynomial regression estimates. The alternative of using classical polynomial regression is also considered and a criterion is proposed to decide whether the nonparametric approach to modeling should be preferred over the classical approach. Illustrative examples are given from the 1990 Ontario Health Survey.

A compositional time series is defined as a multivariate time series in which each of the series has values bounded between zero and one and the sum of the series equals one at each time point. Data with such characteristics are observed in repeated surveys when a survey variable has a multinomial response but interest lies in the proportion of units classified in each of its categories. In this case, the survey estimates are proportions of a whole subject to a unity-sum constraint. In this paper we employ a state space approach for modelling compositional time series from repeated surveys taking into account the sampling errors. The additive logistic transformation is used in order to guarantee predictions and signal estimates bounded between zero and one which satisfy the unity-sum constraint. The method is applied to compositional data from the Brazilian Labour Force Survey. Estimates of the vector of proportions and the unemployment rate are obtained. In addition, the structural components of the signal vector, such as the seasonals and the trends, are produced.

Using data from the Assets and Debts Survey of 1984 and the Survey of Financial Security of 1999, we document the evolution of wealth inequality in Canada between 1984 and 1999. Our main findings are as follows: 1) wealth inequality has increased between 1984 and 1999, 2) the growth in wealth inequality has been associated with substantial declines in real average and median wealth for young couples with children and recent immigrants, 3) real median wealth and real average wealth rose much more among family units whose major income recipient is a university graduate than among other family units, 4) real median and average wealth fell among family units whose major income recipient is aged 25-34 and increased among those whose major income recipient is aged 55 and over, 5) the aging of the Canadian population over the 1984-1999 period has tended to reduce wealth inequality, 6) diverging changes in permanent income do not explain a substantial portion of the growing gap between low-wealth and high-wealth family units. Factors that may have contributed to rising wealth inequality - which cannot be quantified with existing data sets - include differences in the growth of inheritances, inter vivos transfers, rates of return on savings and number of years worked full-time. In particular, rates of return on savings may have increased more for wealthy family units than for their poorer counterparts as a result of the booming stock market during the 1990s.

This, the first issue of 2002 presents an opportunity to recapitulate some of the findings that we have reported during the life of the Bulletin. In an interview, Dr. Fred Gault, Director of Statistics Canada's Science, Innovation and Electronic Information Division, discusses some of the findings on innovation, e-commerce, emerging technologies, Internet use, the telecommunications industry, R&D and commercialization.

Canadian manufacturing firms fall into two groups: The first uses patents and trademarks as a part of successful innovation strategy consisting of regular R&D financed by R&D grants and tax credits introducing world-first innovations. These are usually large firms in the technology-intensive core sector. The second group includes firms of all sizes in all sectors that rely mostly on trade secrets. They typically transfer technology from abroad by introducing Canada-first innovations and rely on government information services more than on R&D grants and tax credits.

This research project provides an overview of diversification and specialization in rural regions and communities for the census years 1981, 1986, 1991 and 1996.

The 2001 Participation and Activity Limitation Survey (PALS) is a post-censal survey of adults and children whose everyday activities are limited because of a condition or health problem. A sample of those persons who answered "Yes" to the 2001 Census disability filter questions were included in the PALS survey population. Approximately 35,000 adults and 8,000 children living in private, and some collective, households in the 10 provinces were selected to participate in the survey. The data were collected in the fall of 2001. The survey was last conducted after the 1991 Census under the title of the 1991 Health and Activity Limitation Survey (HALS). This report presents an overview of the methodological and content changes between the 1991 HALS and the 2001 PALS. The major differences include new census disability filter questions, a new sampling plan and new questionnaire content.

Institutions in the higher education sector usually have records of funds received by them specifically for research and development , and some can provide lists of research projects carried out by staff. The research and development expenditure estimates are based on reports of payments awarded to institutions through the annual survey of the Canadian Association of University Business Officers (CAUBO).

Gross domestic expenditures on research and development (GERD) represents total research and development expenditures performed in a country's national territory during a given year. GERD includes R&D performed within a country and funded from abroad but excludes payments sent abroad for research and development performed in other countries.

For millennia, changes in the earth's atmosphere were the result of natural forces. Over the past century, however, these changes have escalated as a result of human activities-mainly unprecedented growth in global population and consumption of natural resources to increase industrial production-that degrade and destroy the forests and other vital ecosystems essential to atmospheric processes. Such human activities produce large quantities of substances that are released in the air, where over time they can overload natural processes and eventually reach harmful levels. The result is poor air quality in urban and rural areas around the world.

This article addresses the following questions: What is the condition of our outdoor and indoor air? What effects does air quality have on our health and our environment? And what are governments and businesses doing to address air quality concerns?

This paper analyses the impacts of the 1981-82 and 1990-92 recessions on individual services industries. Quarterly changes in real GDP are analysed for each major services industry, and impacts on employment are also examined. The results show that some services industries are more susceptible than others to recessionary downturns in the economy.
