This note by Danny Pfeffermann presents a discussion of the paper “Sample survey theory and methods: Past, present, and future directions” where J.N.K. Rao and Wayne A. Fuller share their views regarding the developments in sample survey theory and methods covering the past 100 years.
Release date: 2017-12-21 - Articles and reports: 85-002-X201700154889Description: This Juristat article uses self-reported data from the 2014 General Social Survey on Canadians' Safety (Victimization) to present information on Canadians' perceptions of personal safety and crime. This includes an analysis of Canadians' sense of safety in specific situations, such as when walking alone after dark in their neighbourhood or waiting for public transportation alone at night. In addition, this article examines Canadians' sense of safety by various socio-demographic and neighbourhood characteristics.Release date: 2017-12-12

This study examines perinatal outcomes among First Nations, Inuit and Métis. The objective is to describe and compare rates of preterm birth, small-for-gestational age birth, large-for-gestational age birth, stillbirth and infant mortality in the three Indigenous groups and the non-Indigenous population.

Rates of low income among immigrants continue to be high relative to the Canadian-born population. This paper examines the rate of chronic low income among immigrants aged 25 or older in Canada during the 2000s. Chronic low income is defined as having a family income under a low income cut-off for five consecutive years or more. A regionally adjusted low-income measure is used for the analysis.

We present research results on sample allocations for efficient model-based small area estimation in cases where the areas of interest coincide with the strata. Although model-assisted and model-based estimation methods are common in the production of small area statistics, utilization of the underlying model and estimation method are rarely included in the sample area allocation scheme. Therefore, we have developed a new model-based allocation named g1-allocation. For comparison, one recently developed model-assisted allocation is presented. These two allocations are based on an adjusted measure of homogeneity which is computed using an auxiliary variable and is an approximation of the intra-class correlation within areas. Five model-free area allocation solutions presented in the past are selected from the literature as reference allocations. Equal and proportional allocations need the number of areas and area-specific numbers of basic statistical units. The Neyman, Bankier and NLP (Non-Linear Programming) allocation need values for the study variable concerning area level parameters such as standard deviation, coefficient of variation or totals. In general, allocation methods can be classified according to the optimization criteria and use of auxiliary data. Statistical properties of the various methods are assessed through sample simulation experiments using real population register data. It can be concluded from simulation results that inclusion of the model and estimation method into the allocation method improves estimation results.

Structural time series models are a powerful technique for variance reduction in the framework of small area estimation (SAE) based on repeatedly conducted surveys. Statistics Netherlands implemented a structural time series model to produce monthly figures about the labour force with the Dutch Labour Force Survey (DLFS). Such models, however, contain unknown hyperparameters that have to be estimated before the Kalman filter can be launched to estimate state variables of the model. This paper describes a simulation aimed at studying the properties of hyperparameter estimators in the model. Simulating distributions of the hyperparameter estimators under different model specifications complements standard model diagnostics for state space models. Uncertainty around the model hyperparameters is another major issue. To account for hyperparameter uncertainty in the mean squared errors (MSE) estimates of the DLFS, several estimation approaches known in the literature are considered in a simulation. Apart from the MSE bias comparison, this paper also provides insight into the variances and MSEs of the MSE estimators considered.

Trade patterns with the U.S. on a regional basis highlight the integration of industries between the two countries; proximity, transport infrastructure and government policy have all contributed to these interdependencies. Indeed, for the year 2016, 11 of Canada’s top 20 trading partners were U.S. states.

The present study sought to determine if large-scale patterns of association between ambient ultraviolet radiation (UVR) and melanoma incidence exist in Canada. Modelled UVR data were spatially linked to members of the 1991 Canadian Census Health and Environment Cohort, a dataset comprising 2.6 million census respondents who were followed for melanoma diagnosis over an 18-year period.

Based on data from the Sun Safety Module of the Canadian Community Health Survey, this study quantifies sunburns and sun protection practices during leisure time, by socioeconomic and demographic characteristics.

This working paper presents a methodology to measure remoteness at the community level. The method takes into account some of the recent literature on the subject, as well as new computational opportunities provided by the integration of official statistics with data from non-official statistical sources. The approach that was used in the computations accounts for multiple points of access to services; it also establishes a continuum between communities with different transportation infrastructures and connectivity while at the same time retaining the information on the community transportation infrastructures in the database. In addition, a method to implement accessibility measures to selected services is also outlined and a sample of accessibility measures are computed.
