  • Articles and reports: 12-001-X197500254828
    Description: The Canadian Travel Survey, 1971 was the largest survey on travel of Canadian residents. This paper describes some important aspects of the methodology. Particular emphasis is given to the development of definitions in relation to the methodology, the sampling technique and interview strategy.

    Description: J.N.K. Rao (1975) derived a general formula for estimating the variance in multistage sample designs. This general formula extends the previous results by Des Raj (1966) to the case where the conditional variance from a given primary sampling unit is a random variable. The authors reviewed Rao's paper for its application to Horvitz-Thompson and Yates-Grundy variance estimators as well as the variance estimator for the random group method by Rao, Hartley and Cochran (1962). The authors present an altered version of the Yates-Grundy variance estimators as a result of Rao's paper.

  • Articles and reports: 12-001-X197500254830
    Description: This paper focuses on the improvement of sample survey estimates in the particular situation where the survey sample, or part of it, is included in a larger sample from which auxiliary information is available. The properties of a method of estimation - sometimes applied in specific circumstances - are investigated and the limitations of its application are found. The application of the method to rotation designs in continuing surveys is more closely studied in the context of composite estimation.

  • Articles and reports: 12-001-X197500254831
    Description: This paper summarizes the results of a telephone experiment conducted in conjunction with the Canadian Labour Force Survey over the period June 1972 to November 1973. Included in the paper is a detailed outline of the purpose and design of the experiment. A discussion of the impact telephone interviewing had on the cost of enumeration, non-response and participation and unemployment rates is given. In addition, interviewer and respondent attitudes toward telephone interviewing are described. Finally, the paper summarizes the experiences gained from this experiment and indicates some areas where further examinations related to telephone interviewing can be carried out.

    Description: A ratio estimate based on an auxiliary variable is considered for the case when the sample is post-stratified using information on another auxiliary variable. The variance of the ratio estimate is derived by the method of linearization [3,4]. An application to subprovincial estimation in the Canadian Labour Force Survey is discussed.

    Description: Most sample surveys in the past have been "descriptive" in the sense that the main objective is the computation of means or totals of a number of characters of interest along with their standard errors. However, in recent years data produced from "descriptive" surveys are also being increasingly used for "analytical" purposes, i.e., for investigating relationships among variables. Also some sample surveys might have primary "analytical goals" in which case the "optimal" designing of such "analytical surveys" becomes important.

    These lecture notes present an account of some recent developments in the analytical studies of sample survey data. Many challenging problems remain to be solved and I hope these notes will provide stimulation for further research in this important area.

    Description:

    Madow [1968] has proposed a two-phase sampling scheme under which response bias can be eliminated from sample surveys by obtaining “true” values for a subsample of the original sample. Often in cases of Censuses or ongoing surveys, the subsample data are not used to correct the main survey estimates but to assess their reliability. The main purpose of this paper is to present methods by which reliability estimates can be obtained when true values can be determined for a subsample of units.

    Description:

    Random rounding is a technique to ensure confidentiality of aggregate statistics. By randomly rounding all the components of a total, independently, together with the random rounding of the total itself, substantial discrepancies may arise when aggregating the published data. This paper presents a procedure which avoids substantial discrepancies while still protecting the concept of confidentiality.

  • Articles and reports: 12-001-X197500100001
    Description: Although a survey is designed to satisfy a specific set of survey constraints, some steps involved in designing a survey, such as stratification, sample allocation and sample selection are common to all surveys. The steps involved in the creation of survey design systems are to identify, develop and implement common methods and procedures for such stages which, when taken together, constitute a survey design. The paper describes some methodological considerations in the development of an automated system for three methods of ratio estimation.

    Description: In 1962, Hartley and Rao derived an asymptotic formula for the joint probability selection for samples selected with unequal probability sampling. In 1966, Connor, derived an exact formula for this joint probability, however, his formulae were very involved. In the present paper the authors, using a modification of Connor's formula derive the exact joint probabilities using a specially designed computer algorithm.

    Description: Statistics Canada is conducting the Survey of Oral Health Care Providers (SOHCP). This survey collects information on the financial and operational characteristics of oral health care providers in Canada. The questions focus on operating revenue and expenses, billing policies, staffing and vacancies, services offered, patient capacity, and operational challenges. Survey results will help assess the current state of the oral health care system in Canada while providing insight into the changes that could impact this sector, including implementation of the Canadian Dental Care Plan. These data are crucial in helping governments devise policies that support access to dental care, improve oral health outcomes for Canadians, and provide an effective work environment for oral health care workers.

    Description: Every new month of data leads to a revision of the previously released data due to such factors as the seasonal adjustment process and a new version of the Generic Survey Universe File (or vintage of the Business Register). As such, the estimates may vary compared with a previous release.

    Description: The Parental Experiences Survey collects information from parents on their experiences, knowledge and behaviours regarding pregnancy, childbirth, and access to and use of health care services. The survey aims to paint a more comprehensive picture of new parents and their infants. The results from the survey will help inform national recommendations for maternal and newborn care as well as improve the mental health and well-being of parents and families across Canada.
