    Geography: Canada
    Description:

    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?

    Description:

    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.

    Description:

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

    This paper describes the Korea National Statistics Office's (KNSO) experiences in data quality assessment and introduces the strategies of institutionalizing the assessment procedure. This paper starts by briefly describing the definition of quality assessment, quality dimensions and indicators at the national level. It introduces the current situation of the quality assessment process in KNSO and lists the six dimensions of quality that have been identified: relevance, accuracy, timeliness, accessibility, comparability and efficiency. Based on the lessons learned from these experiences, this paper points out three essential elements required in an advanced system of data quality assessment: an objective and independent planning system, a set of appropriate indicators and competent personnel specialized in data quality assessment.

    Description:

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.This paper provides an initial look at the performance indicators of statistical agencies in the United States in order to offer a framework for benchmarking performance. As shown by this paper, several agencies have taken extremely different approaches in measuring their performance, both in terms of what they are measuring and how they are measuring it. Sharing this information is the first step toward making these measures more robust and comparable across all US agencies and international statistics offices.

    Description:

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

    In practice, a list of the desired collection units is not always available. Instead, a list of different units that are somehow related to the collection units may be provided, thus producing two related populations, UA and UB. An estimate for UB needs to be created, however, the sampling frame provided is only for the UA population.

    One solution for this problem is to select a sample from UA (sA) and produce an estimate for UB using the existing relationship between the two populations. This process may be referred to as indirect sampling. To assign a selection probability, or an estimation weight, for the survey units, Lavallée (1995) developed the generalized weight share method (GWSM). The GWSM produces an estimation weight that basically constitutes an average of the sampling weights of the units in sA.

    This paper discusses the types of non-response associated with indirect sampling and the possible estimation problems that can occur in the application of the GWSM.

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

    The first round on quality reporting of the statistics produced in Eurostat has almost been completed. This paper presents the experiences so far and, in particular, some of the methodological problems encountered when measuring the quality of the statistics that are produced for international comparisons. A proposal is also presented for indicators that summarize the detailed information provided in these quality reports. Two sets of indicator are discussed: the first more producer-oriented, the second more user-oriented.

    Description:

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

    Methodology for estimating the sampling error of the non-seasonally adjusted estimate of level of the Index of Production (IoP) has previously been developed using Taylor linearization and parametric bootstrap methods, with both producing comparable results. From the study, it was considered that the parametric bootstrap approach would be more practical to implement. This paper describes the methodology that is being developed to estimate the sampling error of the non-seasonally adjusted IoP change using the parametric bootstrap method, along with the data that are needed from the contributing surveys, the assumptions made, and the practical problems encountered during development.

    This paper discusses in detail issues dealing with the technical aspects of designing and conducting surveys. It is intended for an audience of survey methodologists.

    It is customary for statistical agencies to audit tables containing suppressed cells in order to ensure that there is sufficient protection against inadvertent disclosure of sensitive information. If the table contains rounded values, this fact may be ignored by the audit procedure. This oversight can result in over-protection, reducing the utility of the published data. This paper provides correct auditing formulation and gives examples of over-protection.
