    Description:

    The study was undertaken to evaluate some alternative small areas estimators to produce level estimates for unplanned domains from the Italian Labour Force Sample Survey. In our study, the small areas are the Health Service Areas, which are unplanned sub-regional territorial domains and were not isolated at the time of sample design and thus cut across boundaries of the design strata. We consider the following estimators: post-stratified ratio, synthetic, composite expressed as linear combination of synthetic and of post-stratified ratio, and sample size dependent. For all the estimators considered in this study, the average percent relative biases and the average relative mean square errors were obtained in a Monte Carlo study in which the sample design was simulated using data from the 1981 Italian Census.

    Description:

    Dual system estimation (DSE) has been used since 1950 by the U.S. Bureau of Census for coverage evaluation of the decennial census. In the DSE approach, data from a sample is combined with data from the census to estimate census undercount and overcount. DSE relies upon the assumption that individuals in both the census and the sample can be matched perfectly. The unavoidable mismatches and erroneous nonmatches reduce the accuracy of the DSE. This paper reconsiders the DSE approach by relaxing the perfect matching assumption and proposes models to describe two types of matching errors, false matches of nonmatching cases and false nonmatches of matching cases. Methods for estimating population total and census undercount are presented and illustrated using data from 1986 Los Angeles test census and 1990 Decennial Census.

    Description:

    Recently, much effort has been directed towards counting and characterizing the homeless. Most of this work, however, has focused on homeless persons in urban areas. In this paper, we describe efforts to estimate the rate of homelessness in nonurban counties in Ohio. The methods for locating homeless persons and even the definition of homelessness are different in rural areas where there are fewer institutions for sheltering and feeding the homeless. There may also be a problem with using standard survey sampling estimators, which typically require large population sizes, large sample sizes, and small sampling fractions. We describe a survey of homeless persons in nonurban Ohio and present a simulation study to assess the usefulness of standard estimators for a population proportion from a stratified cluster sample.

    Description:

    A regression weight generation procedure is applied to the 1987-1988 Nationwide Food Consumption Survey of the U.S. Department of Agriculture. Regression estimation was used because of the large nonresponse in the survey. The regression weights are generalized least squares weights modified so that all weights are positive and so that large weights are smaller than the least squares weights. It is demonstrated that the regression estimator has the potential for large reductions in mean square error relative to the simple direct estimator in the presence of nonresponse.

  • Stats in brief: 13-604-M1994029
    Description:

    Revised estimates of the Income and Expenditure Accounts (IEA) covering 1990 to 1993 have been released along with the estimates for the first quarter of 1994. These revised estimates reflect the most current source data and seasonal patterns. The annual revision of the different parts of the System of National Accounts is an integrated process. Revised estimates of two other parts of the system, the Balance of International Payments and Financial Flow Accounts, have been released simultaneously. Corresponding revisions to the monthly estimates of the gross domestic product (GDP), by industry and to the Input-Output Accounts at current and constant prices will be available at the end of August.

    The first section of this paper reviews the current revisions to the GDP and the main aggregates. The second section analyses the revision patterns of selected income and expenditure aggregates of the GDP over the period 1980 to 1993. For further information on sources, methods and definitions employed in the IE A, refer to the Guide to the Income and Expenditure Accounts, Catalogue no. 13-603E, no. 1.

    Description:

    Many Canadians with RRSP savings are dipping into these funds before the "normal" retirement age. Who are they, and can their actions be linked to job losses resulting from the recession?
