- Articles and reports: 17-20-0001Description: Demosim: Reports and Analytical Studies, published occasionally by the Centre for Demography of Statistics Canada, features analytical, technical and methodological documents related to Demosim, a microsimulation model designed to produce demographic projections for specific populations such as Indigenous peoples, immigrants and racialized groups. These documents are intended for a broad audience including demographers, researchers, policy makers as well as members of the general public interested in Canadian population trends.Release date: 2022-09-08
- 2. Demosim 2015 ArchivedArticles and reports: 91-621-X2015001Description:
This document briefly describes Demosim, the microsimulation population projection model, how it works as well as its methods and data sources. It is a methodological complement to the analytical products produced using Demosim.

Bayes linear estimator for finite population is obtained from a two-stage regression model, specified only by the means and variances of some model parameters associated with each stage of the hierarchy. Many common design-based estimators found in the literature can be obtained as particular cases. A new ratio estimator is also proposed for the practical situation in which auxiliary information is available. The same Bayes linear approach is proposed for obtaining estimation of proportions for multiple categorical data associated with finite population units, which is the main contribution of this work. A numerical example is provided to illustrate it.

Thompson and Sigman (2000) introduced an estimation procedure for estimating medians from highly positively skewed population data. Their procedure uses interpolation over data-dependent intervals (bins). The earlier paper demonstrated that this procedure has good statistical properties for medians computed from a highly skewed sample. This research extends the previous work to decile estimation methods for a positively skewed population using complex survey data. We present three different interpolation methods along with the traditional decile estimation method (no bins) and evaluate each method empirically, using residential housing data from the Survey of Construction and via a simulation study. We found that a variant of the current procedure using the 95th percentile as a scaling factor produces decile estimates with the best statistical properties.

This paper develops two Bayesian methods for inference about finite population quantiles of continuous survey variables from unequal probability sampling. The first method estimates cumulative distribution functions of the continuous survey variable by fitting a number of probit penalized spline regression models on the inclusion probabilities. The finite population quantiles are then obtained by inverting the estimated distribution function. This method is quite computationally demanding. The second method predicts non-sampled values by assuming a smoothly-varying relationship between the continuous survey variable and the probability of inclusion, by modeling both the mean function and the variance function using splines. The two Bayesian spline-model-based estimators yield a desirable balance between robustness and efficiency. Simulation studies show that both methods yield smaller root mean squared errors than the sample-weighted estimator and the ratio and difference estimators described by Rao, Kovar, and Mantel (RKM 1990), and are more robust to model misspecification than the regression through the origin model-based estimator described in Chambers and Dunstan (1986). When the sample size is small, the 95% credible intervals of the two new methods have closer to nominal confidence coverage than the sample-weighted estimator.
Release date: 2012-12-19 - 6. The Canadian Population in 2011: Age and Sex ArchivedArticles and reports: 98-311-X2011001Geography: Province or territory, Census metropolitan areaDescription:
This 2011 Census analytical document presents key trends emerging from the analysis of age and sex data in Canada, provinces and territories, census metropolitan areas (CMAs), census agglomerations (CAs), regions located outside CMAs and CAs as well as municipalities.

This report compares the aggregate income estimates as published by four different statistical programs. The System of National Accounts provides a portrait of economic activity at the macro economic level. The three other programs considered generate data from a micro-economic perspective: two are survey based (Census of Population and Survey of Labour and Income Dynamics) and the third derives all its results from administrative data (Annual Estimates for Census Families and Individuals). A review of the conceptual differences across the sources is followed by a discussion of coverage issues and processing discrepancies that might influence estimates. Aggregate income estimates with adjustments where possible to account for known conceptual differences are compared. Even allowing for statistical variability, some reconciliation issues remain. These are sometimes are explained by the use of different methodologies or data gathering instruments but they sometimes also remain unexplained.
Release date: 2010-04-06 - Articles and reports: 16-002-X201000111134Geography: CanadaDescription:
Settlements are important hubs for residential, commercial and industrial activity, however, the size, structure and form of settlements over time can have a variety of social, economic and environmental implications. Statistics Canada has developed a new concept and dataset to delineate or map boundaries for Canada's settlements. This article presents some of the early geographic results of this project.
Release date: 2010-03-24 - Articles and reports: 11-522-X200800010981Description:
One of the main characteristics of the 2001 Spanish Census of the Population was the use of an administrative Register of Population (El Padrón) for pre-printing the questionnaires and also the enumerator's record books of the census sections. In this paper we present the main characteristics of the relationship between the Population Register and Census of Population, and the main changes that are being foreseen for the next Census that will take place in 2011.
Release date: 2009-12-03 - 10. Non-response in a random digit dialling survey: The experience of the General Social Survey's Cycle 21 (2007) ArchivedArticles and reports: 11-522-X200800010994Description:
The growing difficulty of reaching respondents has a general impact on non-response in telephone surveys, especially those that use random digit dialling (RDD), such as the General Social Survey (GSS). The GSS is an annual multipurpose survey with 25,000 respondents. Its aim is to monitor the characteristics of and major changes in Canada's social structure. GSS Cycle 21 (2007) was about the family, social support and retirement. Its target population consisted of persons aged 45 and over living in the 10 Canadian provinces. For more effective coverage, part of the sample was taken from a follow-up with the respondents of GSS Cycle 20 (2006), which was on family transitions. The remainder was a new RDD sample. In this paper, we describe the survey's sampling plan and the random digit dialling method used. Then we discuss the challenges of calculating the non-response rate in an RDD survey that targets a subset of a population, for which the in-scope population must be estimated or modelled. This is done primarily through the use of paradata. The methodology used in GSS Cycle 21 is presented in detail.
