Description:

The electronic publication "Low income measures (LIMs)" presents low income statistics, based on annual Survey of Consumer Finances (SCF) data, utilizing the LIMs for estimation of the low income population. LIMs are one alternative to the traditional low income cut-offs (LICOs) for prevalence, depth and composition of the low income population.

Description:

This report presents low income data on an after-tax income concept, including data on how far family incomes are from the LICO or LIM on an after-tax basis (or income deficiency/surplus, popularly referred to as the "poverty gap"). The after-tax low income data are also compared with results from the main or perferred LICO concept.

Description:

This report contains three alternate sets (1980 to present) of historical low income lines to the traditional "Low income cut-offs" (LICOs). The first set, "Low income measures" (LIMs), are set at one-half median adjusted family before-tax income, where "adjusted" indicates a consideration of different needs for families of varying size. The second and third sets are lines on an after-tax basis, using the LICO and LIM methodologies.

Description:

This second edition of R&D tax treatment in Canada: a provincial comparison, uses a method developed by the Conference Board of Canada to compare the tax incentives to do research and development (R&D) in each of the provinces. The results contribute to the analysis of regional differences in science and technology activity in Canada, as part of the work of the Science, Innovation and Electronic Information Division of Statistics Canada.

An example of a regional difference is the tax incentive to do R&D in a province. There is the federal Scientific Research and Experimental Development tax programme, which has regional variations. Six out of ten provinces have their own incentive programmes and tax rates which differ from province to province. The B-Index analysis of the Conference Board provides a means of comparing tax incentives and of providing an indicator.

The statistics presented in this bulletin are derived from our latest survey of industrial research and development activities in Canada. The survey reports on the research and development spending intentions for 1999, the estimates for 1998 and the actual expenditures for 1997 of corporations performing research and development activities in Canada. In 1997, a decision was made to eliminate the short survey forms in favour of administrative data, in order to reduce the response burden.

Description: Fifteen years ago in this series, A. Romaniuc published a comprehensive study of how fertility in Canada had evolved over the century. It described the phenomenal increase of fertility in the postwar period, resulting in the baby boom. With the largest cohorts ever known in Canada, the baby boomers, by their numbers alone, will have left their mark on Canada's social, economic and political structure throughout their life cycle.

Description: At the beginning of this century, a Canadian male could expect to live an average of 47 years and a Canadian female, 50 years. At that time, barely 38% of males and 44% of females reached the respectable age of 65 years. They could then expect to live for roughly another decade.

Description:

As the century draws to a close, there are many topics of interest involving Canada's aboriginal peoples: self-government, land claims, the environment, the criminal justice system, urbanization, the labour market, education, etc. However, one topic receives little attention but could have a major impact on how the others will develop: the demographic growth of aboriginal populations.

In this paper, we assemble data from several household surveys to document how pension coverage of young and older workers has evolved in Canada between the mid-1980s and the mid-1990s. Our main findings are the following. First, both administrative data from the Pension Plans in Canada (PPIC) database and data from household surveys show an increase in RPP coverage for women. In contrast, while PPIC data show a decrease in coverage for men, household surveys indicate no downward trend for males. Second, sample aggregates hide interesting differences within the population. We find that the pension coverage of young workers (aged 25-34) has declined relative to older workers (aged 35-54). Young males have experienced a decline in coverage while RPP coverage has remained fairly stable for older men. In contrast, pension coverage has remained fairly constant for young women but has risen substantially for older women. Third, the decline in unionism and shifts towards industries with low-coverage explain most of the decrease in coverage observed among young men. Fourth, the growth in older women's coverage appears to be the result of their greater propensity to be employed in highly paid/highly covered occupations.

Two-phase sampling designs have been conducted in waves to estimate the incidence of a rare disease such as dementia. Estimation of disease incidence from longitudinal dementia study has to appropriately adjust for data missing by death as well as the sampling design used at each study wave. In this paper we adopt a selection model approach to model the missing data by death and use a likelihood approach to derive incidence estimates. A modified EM algorithm is used to deal with data missing by sampling selection. The non-paramedic jackknife variance estimator is used to derive variance estimates for the model parameters and the incidence estimates. The proposed approaches are applied to data from the Indianapolis-Ibadan Dementia Study.

The U.S. Third National Health and Nutrition Examination Survey (NHANES III) was carried out from 1988 to 1994. This survey was intended primarily to provide estimates of cross-sectional parameters believed to be approximately constant over the six-year data collection period. However, for some variable (e.g., serum lead, body mass index and smoking behavior), substantive considerations suggest the possible presence of nontrivial changes in level between 1988 and 1994. For these variables, NHANES III is potentially a valuable source of time-change information, compared to other studies involving more restricted populations and samples. Exploration of possible change over time is complicated by two issues. First, there was of practical concern because some variables displayed substantial regional differences in level. This was of practical concern because some variables displayed substantial regional differences in level. Second, nontrivial changes in level over time can lead to nontrivial biases in some customary NHANES III variance estimators. This paper considers these two problems and discusses some related implications for statistical policy.

Description:

The objective of this research project is to examine the long-term consequences of being raised in a single parent household. We examine the impact of parental separation or divorce on the adult labour market behaviour of children ten to fifteen years after the event. In particular, we relate the family income and household characteristics of a cohort of individuals who are 16 to 19 years of age in 1982 to their labour market earnings, reliance on social transfers (UI and Income Assistance), and marital/fertility outcomes during the early 1990s, when they are in their late 20s and early 30s. Our data is based upon the linked income tax records developed by us at Statistics Canada, the Survey of Labour and Income Dynamics, and the National Longitudinal Survey of Children and Youth.

Description:

Victimizations are not randomly scattered through the population, but tend to be concentrated in relatively few victims. Data from the U.S. National Crime Victimization Survey (NCVS), a multistage rotating panel survey, are employed to estimate the conditional probabilities of being a crime victim at time t given the victimization status in earlier interviews. Models are presented and fit to allow use of partial information from households that move in or out of the housing unit during the study period. The estimated probability of being a crime victim at interview t given the status at interview (t-l) is found to decrease with t. Possible implications for estimating cross-sectional victimization rates are discusssed.

Description:

A model of secondary school progression has been estimated using data from the 1991 School Leavers Survey conducted by Statistics Canada. The data on which the school progression model was based comprised current educational status and responses to retrospective questions on the timing of schooling events. These data were sufficient for approximate reconstruction of educational event histories of each respondent. The school progression model was designed to be included in a larger, continuous time micro-simulation model. Its main features involve estimation -- by age, month of birth and season for both sexes in each province -- of rates of graduation, of dropout, of return and of dropout graduation. Estimation was reinforced with auxiliary 1991 Census and administative data.

Description:

In a longitudinal survey conducted for k periods some units may be observed for less than k of the periods. Examples include, surveys designed with partially overlapping subsamples, a pure panel survey with nonresponse, and a panel survey supplemented with additional samples for some of the time periods. Estimators of the regression type are exhibited for such surveys. An application to special studies associated with the National Resources Inventory is discussed.

Description:

Multivariate logistic regression, introduced by Glonek and McCullagh (1995) as a generalisation of logistic regression, is useful in the analysis of longitudinal data as it allows for dependent repeated observations of a categorical variable and for incomplete response profiles. We show how the method can be extended to deal with data from complex surveys and we illustrate it on data from the Swiss Labour Force Survey. The effect of the sampling weights on the parameter estimates and their standard errors is considered.

Description:

For longitudinal data, mixed models are often used, since they allow analysts to take account of the correlation between different observations from the same individual. The finite mixture model may be considered as a special case of a mixed model. In this document, attention will be given to the maximum likelihood method. The maximization of the likelihood function for a finite mixture of distributions is generally more difficult than in the usual case of a single distribution and can require considerable time. The objective of this project was therefore primarily to identify the one or more algorithms that best meet the criteria of run time and of efficiency in finding the solution. To achieve this objective, a simulation study was carried out. Only the situation in which the dependent variable is dichotomous was considered. This situation is very useful in practice, since among other things it can be used to model discrete durations, such as the length of time in "low income" status.
