561. Benchmarking of economic time series Archived
Articles and reports: 12-001-X199000214531
Description:
Benchmarking is a method of improving estimates from a sub-annual survey with the help of corresponding estimates from an annual survey. For example, estimates of monthly retail sales might be improved using estimates from the annual survey. This article deals, first with the problem posed by the benchmarking of time series produced by economic surveys, and then reviews the most relevant methods for solving this problem. Next, two new statistical methods are proposed, based on a non-linear model for sub-annual data. The benchmarked estimates are then obtained by applying weighted least squares.

562. Analysis of repeated surveys Archived
Articles and reports: 12-001-X199000214537
Description:
Repeated surveys in which a portion of the units are observed at more than one time point and some units are not observed at some time points are of primary interest. Least squares estimation for such surveys is reviewed. Included in the discussion are estimation procedures in which existing estimates are not revised when new data become available. Also considered are techniques for the estimation of longitudinal parameters, such as gross change tables. Estimation for a repeated survey of land use conducted by the U.S. Soil Conservation Service is described. The effects of measurement error on gross change estimates is illustrated and it is shown that survey designs constructed to enable estimation of the parameters of the measurement error process can be very efficient.

564. A historical perspective on the institutional bases for survey research in the United States Archived
Articles and reports: 12-001-X199000114559
Description:
The basic theme of this paper is that the development of survey methods in the technical sense can only be well understood in the context of the development of the institutions through which survey-taking is done. Thus we consider here survey methods in the large, in order to better prepare the reader for consideration of more formal methodological developments in sampling theory in the mathematical statistics sense. After a brief introduction, we give a historical overview of the evolution of institutional and contextual factors in Europe and the United States, up through the early part of the twentieth century, concentrating on governmental activities. We then focus on the emergence of institutional bases for survey research in the United States, primarily in the 1930s and 1940s. In a separate section, we take special note of the role of the U.S. Bureau of the Census in the study of non-sampling errors that was initiated in the 1940s and 1950s. Then, we look at three areas of basic change in survey methodology since 1960.

565. Randomized response sampling from dichotomous populations with continuous randomization Archived
Articles and reports: 12-001-X198900214566
Description:
A randomized response model for sampling from dichotomous populations is developed in this paper. The model permits the use of continuous randomization and multiple trials per respondent. The special case of randomization with normal distributions is considered, and a computer simulation of such a sampling procedure is presented as an initial exploration into the effects such a scheme has on the amount of information in the sample. A portable electronic device is discussed which would implement the presented model. The results of a study taken, using the electronic randomizing device, is presented. The results show that randomized response sampling is a superior technique to direct questioning for at least some sensitive questions.

566. Estimation of livestock inventories using several area- and multiple-frame estimators Archived
Articles and reports: 12-001-X198900114580
Description:
Estimation of total numbers of hogs and pigs, sows and gilts, and cattle and calves in a state is studied using data obtained in the June Enumerative Survey conducted by the National Agricultural Statistics Service of the U.S. Department of Agriculture. It is possible to construct six different estimators using the June Enumerative Survey data. Three estimators involve data from area samples and three estimators combine data from list-frame and area-frame surveys. A rotation sampling scheme is used for the area frame portion of the June Enumerative Survey. Using data from the five years, 1982 through 1986, covariances among the estimators for different years are estimated. A composite estimator is proposed for the livestock numbers. The composite estimator is obtained by a generalized least-squares regression of the vector of different yearly estimators on an appropriate set of dummy variables. The composite estimator is designed to yield estimates for livestock inventories that are “at the same level” as the official estimates made by the U.S. Department of Agriculture.

567. The sources of census undercount: Findings from the 1986 Los Angeles test census Archived
Articles and reports: 12-001-X198800214590
Description:
This paper presents results from a study of the causes of census undercount for a hard-to-enumerate, largely Hispanic urban area. A framework for organizing the causes of undercount is offered, and various hypotheses about these causes are tested. The approach is distinctive for its attempt to quantify the sources of undercount and isolate problems of unique importance by controlling for other problems statistically.

570. Stratification in the Canadian Labour Force Survey Archived
Articles and reports: 12-001-X198500214372
Description:
The use of a multivariate clustering algorithm to perform stratification for the Labour Force Survey is described. The algorithm developed by Friedman and Rubin (1967) is modified to allow the formation of geographically contiguous strata and to delineate heterogeneous but compact primary sampling units (PSUs) within these strata. Studies dealing with stratification variables, stratification robustness over time, and type of stratification are described.

41. Automation, workers and COVID-19 Archived
Stats in brief: 45-28-0001202000100033
Description:
Over the past few decades, computer technology has gradually changed workplaces, leading to a reduction of routine and manual job tasks, and an increase in non-routine, cognitive tasks. More recent developments in artificial intelligence and machine learning could be even more far-reaching, as they are designed to execute tasks that were traditionally considered non-automatable.

42. Volunteering in Canada: Challenges and opportunities during the COVID-19 pandemic Archived
Stats in brief: 45-28-0001202000100037
Description:
Older generations are more likely than younger generations to be self-isolating and limiting their volunteer activities during the COVID-19 pandemic. In addition, the pandemic has had a series of impacts that vary depending on the type of volunteer organization. Physical distancing and necessary health protection measures quickly affected the provision of face-to-face services, events and meetings involving gatherings of people. At the same time, recent media reports have highlighted many examples of individuals directly assisting others, including picking-up and dropping-off groceries and other supplies in the community, cooking meals, sewing non-medical masks, sharing information and providing emotional support via online social media platforms.
Using data from the 2018 General Social Survey on Giving, Volunteering and Participating (GSS GVP), this article documents how people of various generations contribute to volunteering in Canada. Although these data predate the COVID-19 pandemic, they provide an overview of the challenges and opportunities of volunteering in the current situation.

498. Application of linear and log-linear models to data from complex samples Archived
Articles and reports: 12-001-X198400114351
Description:
Most sample surveys conducted by organizations such as Statistics Canada or the U.S. Bureau of the Census employ complex designs. The design-based approach to statistical inference, typically the institutional standard of inference for simple population statistics such as means and totals, may be extended to parameters of analytic models as well. Most of this paper focuses on application of design-based inferences to such models, but rationales are offered for use of model-based alternatives in some instances, by way of explanation for the author’s observation that both modes of inference are used in practice at his own institution.
Within the design-based approach to inference, the paper briefly describes experience with linear regression analysis. Recently, variance computations for a number of surveys of the Census Bureau have been implemented through “replicate weighting”; the principal application has been for variances of simple statistics, but this technique also facilitates variance computation for virtually any complex analytic model. Finally, approaches and experience with log-linear models are reported.

500. Estimating monthly gross flows in labour force participation Archived
Articles and reports: 12-001-X198300114335
Description:
The Canadian Labour Force Survey is a household survey conducted each month for the purpose of producing point-in-time estimates of the number of persons employed, unemployed and not in the labor force. The survey has a rotating panel design in which all individuals in a sampled household location are interviewed each month, for six consecutive months. In the past, little use has been made of this longitudinal structure, although considerable interest has been expressed in the month-to-month gross flows (transitions) amongst the labour force status categories. In this paper we discuss methods being considered by Statistics Canada for the production of gross flow estimates, but from a model-based perspective.

4. Days of Our Lives: Time Use and Transitions Over the Life Course Archived
Journals and periodicals: 89-584-M
Geography: Canada
Description:
This study provides a detailed analysis of findings based on the 1998 General Social Survey on Time Use, with some analysis of trends over time using the 1986 and 1992 time use surveys. It addresses the question of how life transitions affect time use patterns and quality of life indicators.
Like other resources, time is finite. Unlike other resources, time is shared equally by everyone. The trade-offs people make between competing activities depend largely on the nature of their roles and obligations at each stage of life. These trade-offs say a great deal about a person's lifestyle, preferences and choices, or lack of choice. However, the life cycle has lost the uniformity and formality that it once had. Life-course patterns are now more diverse, and the transitions themselves are more likely to be experienced as extended and complex processes rather than as distinct events. Thus, it becomes important to study the impact of various life transitions on time use and quality of life.
This study examines the following life transitions, with a focus on a comparison of the experiences of women and men:- transition from school to employment- transitions related to union formation and parenthood- transition to retirement- transitions associated with aging: widowhood and changes in living arrangements
