    Description:

    Benchmarking lower level estimates to upper level estimates is an important activity at the United States Department of Agriculture’s National Agricultural Statistical Service (NASS) (e.g., benchmarking county estimates to state estimates for corn acreage). Assuming that a county is a small area, we use the original Fay-Herriot model to obtain a general Bayesian method to benchmark county estimates to the state estimate (the target). Here the target is assumed known, and the county estimates are obtained subject to the constraint that these estimates must sum to the target. This is an external benchmarking; it is important for official statistics, not just NASS, and it occurs more generally in small area estimation. One can benchmark these estimates by “deleting” one of the counties (typically the last one) to incorporate the benchmarking constraint into the model. However, it is also true that the estimates may change depending on which county is deleted when the constraint is included in the model. Our current contribution is to give each small area a chance to be deleted, and we call this procedure the random deletion benchmarking method. We show empirically that there are differences in the estimates as to which county is deleted and that there are differences of these estimates from those obtained from random deletion as well. Although these differences may be considered small, it is most sensible to use random deletion because it does not give preferential treatment to any county and it can provide small improvement in precision over deleting the last one benchmarking as well.

    Description:

    This paper presents a new algorithm to solve the one-dimensional optimal stratification problem, which reduces to just determining stratum boundaries. When the number of strata H and the total sample size n are fixed, the stratum boundaries are obtained by minimizing the variance of the estimator of a total for the stratification variable. This algorithm uses the Biased Random Key Genetic Algorithm (BRKGA) metaheuristic to search for the optimal solution. This metaheuristic has been shown to produce good quality solutions for many optimization problems in modest computing times. The algorithm is implemented in the R package stratbr available from CRAN (de Moura Brito, do Nascimento Silva and da Veiga, 2017a). Numerical results are provided for a set of 27 populations, enabling comparison of the new algorithm with some competing approaches available in the literature. The algorithm outperforms simpler approximation-based approaches as well as a couple of other optimization-based approaches. It also matches the performance of the best available optimization-based approach due to Kozak (2004). Its main advantage over Kozak’s approach is the coupling of the optimal stratification with the optimal allocation proposed by de Moura Brito, do Nascimento Silva, Silva Semaan and Maculan (2015), thus ensuring that if the stratification bounds obtained achieve the global optimal, then the overall solution will be the global optimum for the stratification bounds and sample allocation.

    Description:

    Demographers are facing increasing pressure to disaggregate their estimates and forecasts by characteristics such as region, ethnicity, and income. Traditional demographic methods were designed for large samples, and perform poorly with disaggregated data. Methods based on formal Bayesian statistical models offer better performance. We illustrate with examples from a long-term project to develop Bayesian approaches to demographic estimation and forecasting. In our first example, we estimate mortality rates disaggregated by age and sex for a small population. In our second example, we simultaneously estimate and forecast obesity prevalence disaggregated by age. We conclude by addressing two traditional objections to the use of Bayesian methods in statistical agencies.

    Description:

    This article focuses on the emergence of the next generation of Canadian farm operators. The rise of adaptive and educated female farm operators in synergy with progressive and resourceful young farm operators is changing the perception of the typical farmer.

    Faced with modernizing farming practises, female and young farm operators are placing greater emphasis on educational attainment. While agricultural operations evolve into large-scale, capital-intensive entities, female and young farm operators are adapting by diversifying revenue streams and acquiring farm land through innovative methods.

    International trade in services is covered by a set of rules documented in the General Agreement on Trade in Services (GATS). The GATS is a multilaterally agreed legal framework for trade in services, which provides a system of enforceable obligations and commitments for services trade that apply to all members of the World Trade Organization. The GATS defines trade in services as the supply of a service through any of the four modes of supply: cross border, consumption abroad, commercial presence, and the presence of natural persons.

    Description:

    This study provides new evidence on TB-related hospitalizations among new immigrants to Canada. It uses a unique linked data file (2000-to-2013 Longitudinal Immigration Database (IMDB) linked to the Canadian Institute for Health Information's Discharge Abstract Database (DAD) from 2001/2002 to 2013/2014) that brings together information from immigrant landing records and hospital data for a maximum of 13 years to identify a TB-related hospital event after landing. Specifically, this paper provides a profile of the timing of TB-related acute care hospitalization, starting from the time of landing among immigrants who officially landed in Canada from 2000 to 2013, as well as an estimation of the burden of TB hospital care in Canada incurred by these recent immigrants relative to the total Canadian population.

    Description:

    Record linkage has been identified as a potential mechanism to add treatment information to the Canadian Cancer Registry (CCR). The purpose of the Canadian Cancer Treatment Linkage Project (CCTLP) pilot is to add surgical treatment data to the CCR. The Discharge Abstract Database (DAD) and the National Ambulatory Care Reporting System (NACRS) were linked to the CCR, and surgical treatment data were extracted. The project was funded through the Cancer Data Development Initiative (CDDI) of the Canadian Partnership Against Cancer (CPAC).

    The CCTLP was developed as a feasibility study in which patient records from the CCR would be linked to surgical treatment records in the DAD and NACRS databases, maintained by the Canadian Institute for Health Information. The target cohort to whom surgical treatment data would be linked was patients aged 19 or older registered on the CCR (2010 through 2012). The linkage was completed in Statistics Canada’s Social Data Linkage Environment (SDLE).

    Description:

    This analytical study uses Canadian Vehicle Survey data for 2000 to explain road use characteristics of young and aging drivers on a national basis. The analysis examines differences between two age groups - those aged 24 and under and those aged 55 and over - with the remainder of the population, those aged 25 to 54.

    The focus of the study is on when and why drivers choose to make road trips, and how the driving population compares with the population as a whole. Driver characteristics were compared with Canadian motor vehicle traffic collision statistics published by Transport Canada (1999) as a means of putting driving exposure into perspective.
