This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The existing sources of demographic data for South Africa have different strengths and limitations that make them inadequate for calibration of sample weights in post-apartheid South African household surveys. The official mid-year population estimates produced by Statistics South Africa do not cover the entire period, the previously used Actuarial Society of South Africa model has become outdated, and the updated Thembisa model does not produce estimates by population groups. We introduce the Centre for Actuarial Research and Centre for Actuarial Research-Statistics South Africa models, two sources of consistent demographic data disaggregated by age groups, sex, and population groups as well as by province from 1990 to 2022. When the two model estimates are used to calibrate the South African household survey series, there are no substantial differences in several of the estimates that are evaluated. However, there are notable differences in the White and Indian/Asian population groups between the Statistics South Africa estimates and the Centre for Actuarial Research model in the later years.
Download or read book Re weighting the South African National Household Survey Data to Create a Consistent Series Over Time written by Nicola Branson and published by . This book was released on 2011 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the absence of established longitudinal panel surveys in South African, national cross-sectional household survey data are frequently used to analyse change. When these data are stacked side-byside, however, inconsistencies both in time trends and between household and person level data are found. This study uses a new set of weights calibrated to the ASSA 2003 model totals using a cross entropy estimation approach. This approach is favoured because the calculated weights are similar to the initial sample weights (and hence retain the survey design benefits) but match to a series of age-sex-race and province marginal totals that are consistent over time. The weights are publicly available for a fourteen year period between 1994 and 2007 "--Page [1].

Book excerpt: Survey Weights: A Step-by-Step Guide to Calculation is the first guide geared toward Stata users that systematically covers the major steps taken in creating survey weights. These weights are used to project a sample to some larger population and can be computed for either probability or nonprobability samples. Sample designs can range from simple, single-stage samples to more complex, multistage samples, each of which may use specialized steps in weighting to account for selection probabilities, nonresponse, inaccurate coverage of a population by a sample, and auxiliary data to improve precision and compensate for coverage errors. The authors provide many examples with Stata code.

Download or read book Aging in Sub Saharan Africa written by National Research Council and published by National Academies Press. This book was released on 2006-11-10 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: In sub-Saharan Africa, older people make up a relatively small fraction of the total population and are supported primarily by family and other kinship networks. They have traditionally been viewed as repositories of information and wisdom, and are critical pillars of the community but as the HIV/AIDS pandemic destroys family systems, the elderly increasingly have to deal with the loss of their own support while absorbing the additional responsibilities of caring for their orphaned grandchildren. Aging in Sub-Saharan Africa explores ways to promote U.S. research interests and to augment the sub-Saharan governments' capacity to address the many challenges posed by population aging. Five major themes are explored in the book such as the need for a basic definition of "older person," the need for national governments to invest more in basic research and the coordination of data collection across countries, and the need for improved dialogue between local researchers and policy makers. This book makes three major recommendations: 1) the development of a research agenda 2) enhancing research opportunity and implementation and 3) the translation of research findings.

Available in PDF, EPUB and Kindle. Book excerpt: "The ongoing COVID-19 pandemic marks the most significant, singular global disruption since World War II, with health, economic, political, and security implications that will ripple for years to come." -Global Trends 2040 (2021) Global Trends 2040-A More Contested World (2021), released by the US National Intelligence Council, is the latest report in its series of reports starting in 1997 about megatrends and the world's future. This report, strongly influenced by the COVID-19 pandemic, paints a bleak picture of the future and describes a contested, fragmented and turbulent world. It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

Download or read book Practical Tools for Designing and Weighting Survey Samples written by Richard Valliant and published by Springer Science & Business Media. This book was released on 2013-05-16 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: Survey sampling is fundamentally an applied field. The goal in this book is to put an array of tools at the fingertips of practitioners by explaining approaches long used by survey statisticians, illustrating how existing software can be used to solve survey problems, and developing some specialized software where needed. This book serves at least three audiences: (1) Students seeking a more in-depth understanding of applied sampling either through a second semester-long course or by way of a supplementary reference; (2) Survey statisticians searching for practical guidance on how to apply concepts learned in theoretical or applied sampling courses; and (3) Social scientists and other survey practitioners who desire insight into the statistical thinking and steps taken to design, select, and weight random survey samples. Several survey data sets are used to illustrate how to design samples, to make estimates from complex surveys for use in optimizing the sample allocation, and to calculate weights. Realistic survey projects are used to demonstrate the challenges and provide a context for the solutions. The book covers several topics that either are not included or are dealt with in a limited way in other texts. These areas include: sample size computations for multistage designs; power calculations related to surveys; mathematical programming for sample allocation in a multi-criteria optimization setting; nuts and bolts of area probability sampling; multiphase designs; quality control of survey operations; and statistical software for survey sampling and estimation. An associated R package, PracTools, contains a number of specialized functions for sample size and other calculations. The data sets used in the book are also available in PracTools, so that the reader may replicate the examples or perform further analyses.

Download or read book Improving the targeting of fertilizer subsidy programs in Africa south of the Sahara Perspectives from the Ghanaian experience written by Houssou, Nazaire and published by Intl Food Policy Res Inst. This book was released on 2017-03-17 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper assesses whether fertilizer subsidy programs can be better targeted to resource-poor farmers using the case of Ghana and proxy means test approaches. Past fertilizer subsidy programs in the country have not been particularly targeted to the poor, even as targeting poor and smallholder farmers has become key in the program implementation guidelines. As a result, many poor farmers have not benefited from past programs. Our results show that targeting approaches based on proxy means tests that use the correlates of poverty to select beneficiary farmers can potentially improve the poverty outreach and costeffectiveness of Ghana’s fertilizer subsidy programs. Therefore, we propose that the proxy means test approach should be considered for implementing Ghana’s fertilizer subsidy programs, first in a pilot project involving a few communities, and later, if found successful, in a full-scale program.
Download or read book Household Demography and Household Modeling written by Evert van Imhoff and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992, a summer course 'Demographic Perspectives on Living Arrangements' as well as a one-day workshop 'Recent Issues in Household Modelling' were held in Wassenaar, The Netherlands. This volume is based on the lectures delivered during the summer course, as well as on the presentations made in the workshop. As such, the present volume combines the two elements of transfer of knowledge, on the one hand, and updating the state-of-the-art in the field of household demography, especially in household modelling, on the other hand. In organizing the contents and structure of this volume, we have aimed at creating a book that covers the field of household demography and household modelling in a certain logical and comprehensive way. The purpose of this book is to offer a comprehensive treatment of recent developments in various aspects of the growing field of household demography. Since these recent developments have particularly occurred in household analysis and modelling, these topics will receive special emphasis. The book was written for demographers, social scientists, and planners who are involved in the study and projection of popUlation in general, and of households in particular.
