1. Using behavior coding to evaluate the effectiveness of dependent interviewing Archived
Articles and reports: 12-001-X200800210755
Description:
Dependent interviewing (DI) is used in many longitudinal surveys to "feed forward" data from one wave to the next. Though it is a promising technique which has been demonstrated to enhance data quality in certain respects, relatively little is known about how it is actually administered in the field. This research seeks to address this issue through behavior coding. Various styles of DI were employed in the English Longitudinal Study of Ageing (ELSA) in January, 2006, and recordings were made of pilot field interviews. These recordings were analysed to determine whether the questions (particularly the DI aspects) were administered appropriately and to explore the respondent's reaction to the fed-forward data. Of particular interest was whether respondents confirmed or challenged the previously-reported information, whether the prior wave data came into play when respondents were providing their current-wave answers, and how any discrepancies were negotiated by the interviewer and respondent. Also of interest was to examine the effectiveness of various styles of DI. For example, in some cases the prior wave data was brought forward and respondents were asked to explicitly confirm it; in other cases the previous data was read and respondents were asked if the situation was still the same. Results indicate varying levels of compliance in terms of initial question-reading, and suggest that some styles of DI may be more effective than others.

2. Determining the optimum strata boundary points using dynamic programming Archived
Articles and reports: 12-001-X200800210761
Description:
Optimum stratification is the method of choosing the best boundaries that make strata internally homogeneous, given some sample allocation. In order to make the strata internally homogenous, the strata should be constructed in such a way that the strata variances for the characteristic under study be as small as possible. This could be achieved effectively by having the distribution of the main study variable known and create strata by cutting the range of the distribution at suitable points. If the frequency distribution of the study variable is unknown, it may be approximated from the past experience or some prior knowledge obtained at a recent study. In this paper the problem of finding Optimum Strata Boundaries (OSB) is considered as the problem of determining Optimum Strata Widths (OSW). The problem is formulated as a Mathematical Programming Problem (MPP), which minimizes the variance of the estimated population parameter under Neyman allocation subject to the restriction that sum of the widths of all the strata is equal to the total range of the distribution. The distributions of the study variable are considered as continuous with Triangular and Standard Normal density functions. The formulated MPPs, which turn out to be multistage decision problems, can then be solved using dynamic programming technique proposed by Bühler and Deutler (1975). Numerical examples are presented to illustrate the computational details. The results obtained are also compared with the method of Dalenius and Hodges (1959) with an example of normal distribution.

3. Small area estimation under a two-part random effects model with application to estimation of literacy in developing countries Archived
Articles and reports: 12-001-X200800210764
Description:
This paper considers situations where the target response value is either zero or an observation from a continuous distribution. A typical example analyzed in the paper is the assessment of literacy proficiency with the possible outcome being either zero, indicating illiteracy, or a positive score measuring the level of literacy. Our interest is in how to obtain valid estimates of the average response, or the proportion of positive responses in small areas, for which only small samples or no samples are available. As in other small area estimation problems, the small sample sizes in at least some of the sampled areas and/or the existence of nonsampled areas requires the use of model based methods. Available methods, however, are not suitable for this kind of data because of the mixed distribution of the responses, having a large peak at zero, juxtaposed to a continuous distribution for the rest of the responses. We develop, therefore, a suitable two-part random effects model and show how to fit the model and assess its goodness of fit, and how to compute the small area estimators of interest and measure their precision. The proposed method is illustrated using simulated data and data obtained from a literacy survey conducted in Cambodia.

5. Understanding Internet Usage Among Broadband Households: A Study of Household Internet Use Survey Data Archived
Articles and reports: 88F0006X2008003
Description:
Canadians were early adopters of broadband Internet services, and Canada continues to lead the G7 group of industrialized countries in broadband penetration. In 2003, approximately 65% of Canadian households with home Internet connections had broadband connections, a number that increased to 81% in 2005. It is assumed that the high adoption rates reflect a population that is well-prepared to use the Internet to access education, health, government, business and entertainment services. However, the adoption of broadband alone is not a panacea for users. How the broadband connection is used is critical to understanding impacts. By analyzing Statistics Canada's Household Internet Use Survey (HIUS) data, this paper makes the case that not all broadband households are the same. It demonstrates that understanding how often and for what purposes Canadian households are using their broadband connections allows for a fuller examination of Internet usage than simply measuring broadband access rates. As the data will show, broadband access does not imply full usage of broadband services. This study identifies differences within broadband households, and explains why it is important to recognize the differences in their usage behaviours.

6. Projecting the Future Availability of the Informal Support Network of the Elderly Population and Assessing Its Impact on Home Care Services Archived
Articles and reports: 91F0015M2008009
Geography: Canada
Description:
In Canada, there has been growing discussion over the aging of the population and other socio-demographic trends which affect the availability of the informal support network of the elderly population. Noting the lower fertility rates of baby boomers, the increased participation of women in the labour force and changing family structure in terms of increased divorce and reconstituted families, assumptions of continued high level assistance from informal support networks - family and friends - are often criticized.
The main objective of this research is to project the future availability of informal support network to meet the need for assistance in performing everyday activities among the disabled elderly population for the period 2001 to 2031. The research examined both sides - supply and demand - of the projected increases in need for assistance for disabled older persons. Future trends are analyzed in terms of demand for support, (that is, changes in the rates of disability among the elderly population), and supply of informal support, (which is largely related to the extent and composition of the family network). Data from two national surveys, the 1996 National Population Health Survey (NPHS) and the 1996 General Social Survey (GSS), are used to identify factors associated with disability and sources of assistance among the elderly population. These results were entered into Statistics Canada's LifePaths microsimulation model to project the use of informal and formal networks in the future. The model also incorporates three disability scenarios to test the sensitivity of the projections when different assumptions are considered. The implications of these trends on the future need for chronic home care services are discussed.
The results show that for the period 2001 to 2031, the average annual growth rate of the number of disabled elderly needing assistance could be about 2.5%. However, the sensitivity analysis shows that an improvement in the health of the population could reduce in a non negligible way this growth rate.
The results also show that, all things being equal, a greater proportion of elderly persons living with a spouse would relieve some of the pressure on the formal network. This positive effect could be dampened in part when joint survivorship is also meaning joint disability.

7. Terms of trade in central Canada Archived
Articles and reports: 11-010-X200801210765
Geography: Province or territory
Description:
This paper examines Ontario's and Quebec's adjustments to the resource boom. Higher commodity prices, an appreciating dollar, and increased foreign competition between 2002 and 2007 led to a restructuring of the Central Canadian economies. The restructuring manifested itself in all areas of the economy: manufacturing employment and output declined, while services and construction rose; within manufacturing there were declines across most industries in Ontario, and a shift away from consumer products towards capital products in Quebec; purchasing power increased in Ontario and Quebec as export and import prices adjusted.

10. The Resource Boom: Impacts on Provincial Purchasing Power Archived
Articles and reports: 11-624-M2008021
Geography: Province or territory
Description:
The present study illustrates the differential impact on regional economies of relative price changes stemming from commodity price movements, exchange rate changes and changes in international manufactured goods prices. It focuses on Canadian provinces, which are a large, geographically distributed federation of regional economies with widely differing economic bases. In this regard, the study illuminates an important method for examining regional economic performance that is particularly well suited to federations such as Russia or the European Monetary Union, or to large countries such as the United States.
