This paper describes the design and adjustment methods for handling movers in the U.S. Early Childhood Longitudinal Study, Kindergarten Class of 1998/99 (ECLS-K). The paper also discusses how subsampling movers and adjusting for mover non-response affect the survey goal of accurately characterizing the academic growth and experiences of children.

This report provides information on various aspects of the data on mobility and migration. It provides a review of the questions, concepts and definitions, along with a discussion of limitations inherent in the measurement of one-year and five-year mobility and migration in the censuses of Canada. Some background is provided on the processing of mobility data, from collection through to retrieval. The historical comparability of mobility and migration data from 1961 to 2001 is examined in terms of conceptual and processing changes. The analysis of the quality of 2001 data focuses mainly on the quality at the national and provincial level. Where possible, the five-year data and the one-year data are discussed separately.

The estimation of intergenerational earnings mobility is rife with measurement problems since the research does not observe permanent, lifetime earnings. Nearly all studies make corrections for mean variation in earnings because of the age differences among respondents. Recent works employ average earnings or instrumental variable methods to address the effects of measurement error as a result of transitory earnings shocks and mis-reporting. However, empirical studies of intergenerational mobility have paid no attention to the changes in earnings variance across the life cycle suggested by economic models of human capital investment.
Using information from the Intergenerational Income Data from Canada and the National Longitudinal Survey and Panel Study of Income Dynamics from the United States, this study finds a strong association between age at observation and estimated earnings persistence. Part of this age-dependence is related to a general increase in transitory earnings variance during the collection of data. An independent effect of life cycle investment is also identified. These findings are then applied to the variation among intergenerational earnings persistence studies. Among studies with similar methodologies, one-third of the variance in published estimates of earnings persistence is attributable to cross-study differences in the age of responding fathers. Finally, these results call into question tests for the importance of credit constraints based on measures of earnings at different points in the life cycle.

Temporary mobility is hypothesized to contribute toward within-household coverage error since it may affect an individual's determination of "usual residence" - a concept commonly applied when listing persons as part of a household-based survey or census. This paper explores a typology of temporary mobility patterns and how they relate to the identification of usual residence. Temporary mobility is defined by the pattern of movement away from, but usually back to a single residence over a two-three month reference period. The typology is constructed using two dimensions: the variety of places visited and the frequency of visits made. Using data from the U.S. Living Situation Survey (LSS) conducted in 1993, four types of temporary mobility patterns are identified. In particular, two groups exhibiting patterns of repeat visit behavior were found to contain more of the types of people who tend to be missed during censuses and surveys. Log-linear modeling indicates spent away and demographic characteristics.

The estimation of the population by age, sex and marital status for each province is a difficult task, principally because of migration. The characteristics of migrants are available only from responses to the census. Until 1991, the census included only the question on place of residence five years ago. Thus, a person who had a different residence five years earlier was considered as a migrant and was attributed the characteristics reported for him/her at the time of the census. However, the respondent had up to five years to change characteristics, particularly those relating to marital status.
Since 1991, the census has asked a question on the place of residence one year ago. The same procedure attributes to the migrant the characteristics reported one year earlier, but this time there is only one year to change them.The article describes, in some detail, the methods now used by Statistics Canada to estimate the characteristics of migrants and evaluates the advantages of using the data on place of residence one year ago.
Release date: 1997-12-23 - 6. Project on Matching Census 1986 Database and Manitoba Health Care Files: Private Households Component ArchivedArticles and reports: 11F0019M1996091Geography: Province or territoryDescription:
Introduction: In the current economic context, all partners in health care delivery systems, be they public or private, are obliged to identify the factors that influence the utilization of health care services. To improve our understanding of the phenomena that underlie these relationships, Statistics Canada and the Manitoba Centre for Health Policy and Evaluation have just set up a new database. For a representative sample of the population of the province of Manitoba, cross-sectional microdata on individuals' health and socio-economic characteristics were linked with detailed longitudinal data on utilization of health care services.
Data and methods: The 1986-87 Health and Activity Limitation Survey, the 1986 Census and the files of Manitoba Health were matched (without using names or addresses) by means of the CANLINK software. In the pilot project, 20,000 units were selected from the Census according to modern sampling techniques. Before the files were matched, consultations were held and an agreement was signed by all parties in order to establish a framework for protecting privacy and preserving the confidentiality of the data.
Results: A matching rate of 74% was obtained for private households. A quality evaluation based on the comparisons of names and addresses over a small subsample established that the overall concordance rate among matched pairs was 95.5%. The match rates and concordance rates varied according to age and household composition. Estimates produced from the sample accurately reflected the socio-demographic profile, mortality, hospitalization rate, health care costs and consumption of health care by Manitoba residents.
Discussion: The matching rate of 74% was satisfactory in comparison with the response rates reported in most population surveys. Because of the excellent concordance rate and the accuracy of the estimates obtained from the sample, this database will provide an adequate basis for studying the association between socio-demographic characteristics, health and health care utilization in province of Manitoba.
