    Description:

    In this paper we present two applications of spatial smoothing using data collected in a large scale economic survey of Australian farms: one a small area and the other a large area application. In the small area application, we describe how the sample weigths can be spatially smoothed in order to improve small area estimates. In the large area application, we give a method for spatially smoothing and then mapping the survey data. The standard method of weighting in the survey is a variant of linear regression weighting. For the small area application, this method is modified by introducing a constraint on the spatial variability of the weights. Results from a small scale empirical study indicate that this decreases the variance of the small area estimators as expected, but at the cost of an increase in their bias. In the large area application, we describe the nonparametric regression method used to spatially smooth the survey data as well as techniques for mapping this smoothed data using a Geographic Information System (GIS) package. We also present the results of a simulation study conducted to determine the most appropriate method and level of smoothing for use in the maps.

    Description:

    Telephone surveys in the U.S. are subject to coverage bias because about 6 percent of all households do not have a telephone at any particular point in time. The bias resulting from this undercoverage can be important since those who do not have a telephone are generally poorer and have other characteristics that differ from the telephone population. Poststratification and the other usual methods of adjustment often do not fully compensate for this bias. This research examines a procedure for adjusting the survey estimates based on the observation that some households have a telephone for only part of the year, often due to economic circumstances. By collecting data on interruptions in telephone service in the past year, statistical adjustments of the estimates can be made which may reduce the bias in the estimates but which at the same time increase variances because of greater variability in weights. This paper considers a method of adjustment using data collected from a national telephone survey. Estimates of the reductions in bias and the effect on the mean square error of the estimates are computed for a variety of statistics. The results show that when the estimates from the survey are highly related to economic conditions the telephone interruption adjustment procedure can improve the mean square error of the estimates.

    Description:

    Within a survey re-engineering context, the combined methodology developed in the paper addresses the problem of finding the minimal sample size for the generalized regression estimator in skewed survey populations (e.g., business, institutional, agriculture populations). Three components necessary in identifying an efficient sample redesign strategy involve i) constructing an efficient partitioning between the “take-all” and “sampled” groups, ii) identifying an efficient sample selection scheme, and iii) finding the minimal sample size required to meet the desired precision constraint(s). A scheme named the “Transfer Algorithm” is devised to address the first issue (Pandher 1995) and is integrated with the other two components to arrive at a combined iterative procedure that converges to a globally minimal sample size and population partitioning under the imposed precision constraint. An equivalence result is obtained allowing the solution to the proposed algorithm to be alternatively determined in terms of simple quantities computable directly from the population auxiliary data. Results from the application of the proposed sample redesign methodology to the Local Government Survey in Ontario are reported. A 52% reduction in the total sample size is achieved for the regression estimator of the total at a minimum coefficient of variation of 2%.

    Description:

    Unpredictability" and "transformation" are words often used to describe the contemporary labour market. Debate continues about the implications of the disruption of stable career and work patterns which were assumed to have been the norm in the Canadian workplace. Teaching, because it is the largest profession in Canada, is a useful venue for examining these labour market dynamics, especially transitions into and out of the profession. These entry and exit transitions, which are the central theme of this paper, are also of interest in a profession like teaching where university graduates have traditionally enjoyed a tight link to an established labour market.

    Description: Industrial R&D expenditures for environmental protection represented 2% of total R&D expenditures in 1995. This small share, which has been maintained since 1990, is likely to be an underestimate due to those R&D investments mainly undertaken to improve production efficiency. In such cases, R&D expenditures on environmental protection would not be reported despite the additional benefits to the environment that may be achieved.

    Description:

    Often one of the key objectives of multi-purpose demographic surveys in the U.S. is to produce estimates for small domains of the population such as race, ethnicity, and income. Geographic-based oversampling is one of the techniques often considered for improving the reliability of the small domain statistics using block or block group information from the Bureau of the Census to identify areas where the small domains are concentrated. This paper reviews the issues involved in oversampling geographical areas in conjunction with household screening to improve the precision of small domain estimates. The results from an empirical evaluation of the variance reduction from geographic-based oversampling are given along with an assessment of the robustness of the sampling efficiency over time as information for stratification becomes out of date. The simultaneous oversampling of several small domains is also discussed.

    Description:

    This report is an examination of crime data reported to the Uniform Crime Reporting (UCR) survey during 1996. The data are presented within the context of both short and long term trends. Every year since 1962, Canada's police agencies have reported incidents that come to their attention to the UCR survey. Analyses in this report focus on trends in violent crime, property crime, impaired driving offences, drug offences and yotuth crime. Crime rates are examined at the national, provincial/territorial and major metropolitan levels. The trend in Canada's crime rate is put into perspective by comparing it with trends in police-reported crime form the United States and England and Wales. Also, comparisons between Canadian crime statistics and results from a recent victimization survey are drawn. Specific types of violent crime such as "home- invasions", wife assault and violent incidents involving weapons continue to be a concern to Canadians. Due to limits in the way crime statistics are collected from Canada's police agencies, it has traditionally been difficults to measure these areas. While national statistics are still unavailable, this Juristat will, for the first time, present trends for these crimes as reported by a sample of police agencies from 1993 to 1996.

    Description:

    Homicide tends to receive more media attention and consequently closer public scrutiny than any other criminal act. The act itself, especially if cruel in nature or targeting defenceless members of society, promotes fear in the general public. Despite a growing concern among Canadians about threats of attack or violence, the homicide rate has gradually been declining since the mid 1970s.

    Description:

    Widely used summary measures of inequality or the "disappearing middle class" are potentially misleading. Divergences between evidence cited and conclusions drawn include failing to distinguish the concepts of inequality and polarization, and using scalar ôinequalityö measures which are not consistent with rankings based on Lorenz curves. In addition, inappropriate claims about trends in inequality can arise from focusing on only a sub-population such as full-time male workers, and failing to account for sampling variability. These divergences are illustrated using Canadian data on labour incomes over the 1967 to 1994 period.

    The purpose of this report is to reduce the level of confusion arising from the use of crime data originating from two very different sources (i.e., the Uniform Crime Reporting Survey - UCR and the General Social Survey - GSS) and to inform discussions about which is the better measure of crime. It explains why the findings based on these data sources diverge and summarizes the major differences between the two surveys.
