Book Description
In order to assess the coverage and the quality of the census data of the 1991 census, the Census Validation Survey (CVS) was carried out by the Social Survey Division of OPCS. The survey produced estimates of household spaces, households, and persons together with 95 percent confidence intervals. The CVS estimated the census undercount from six different samples, five of which were drawn from the census records and hence dependent. From the comparison between 1991 census results and demographic estimates, it was felt that CVS failed to estimate the true undercount figure of the 1991 census. Moreover, the CVS methodology was unable to estimate the undercount by age, sex, race, and geographic categories. This book presents methods for estimating population by age, sex, and race, as well as geographic categories. Three different estimators, Chandra-Sekar, Greenfield, and El-Sayed Nour, using information from two different sources (census and survey), are discussed. Adjustment factors are generally computed as the ratios of these estimates to the census counts. Average estimates from these three estimators may produce better adjustment factors. Models to produce more accurate estimates of the size of the closed population by using a second sample by matching with census and survey are also discussed. The models we present provide a mechanism for separating out the dependence between census and survey data induced by individual heterogeneity. The resulting data take the form of 2x2x2 table, in which only one of the eight cells is unknown. Using log-linear quasi-symmetry models we describe how to estimate the expected values of the observable cells of this table. To estimate the populations for local authorities (LA), a regression method is presented. The resulting estimates are found to be more accurate than the CVS estimates and were also close to the 1991 demographic estimates. We describe a methodology for estimating the accuracy of the dual systems estimates of population with the help of hypothetical data. The methodology is based on decompositions of the total error into components, such as sampling error, matching error, and other nonsampling errors. An imputation method and some recommendations are also discussed.

Book Description
This accessible and clearly-structured book offers a comprehensive insight into the methods and principles of epidemiological study alongside an analysis of the broad context in which epidemiological work is undertaken. Chapters on sources of epidemiological data, on epidemiological study designs and on basic statistical measures for epidemiological studies are used to introduce the reader to the traditional underpinnings of epidemiological work. Attention then shifts to a wider canvas. Consideration is given to the critical reading of epidemiological research both as a way of demonstrating how different aspects of epidemiological study come together in published work and as the basis for a discussion of the centrality of epidemiological research in the development of evidence-based health care. The key facets of evidence-based health care are assessed. A more discursive and critical assessment of epidemiology is also presented in which attention is drawn to the need to develop alternative epidemiologies which draw on lay knowledge and recognise the socio-political context of factors influencing health status. The book concludes with a description of the everyday practice of epidemiology in a UK health authority context.

Book Description
The collection of reliable and comprehensive data on the magnitude, composition and distribution of a country’s population is essential in order for governments to provide services, administer effectively and guide a country’s development. The primary source of basic demographic statistics is frequently a population census, which provides hugely important data sets for policy makers, practitioners and researchers working in a wide range of different socio-demographic contexts. The Routledge Handbook of Census Resources, Methods and Applications provides a comprehensive and authoritative guide to the collection, processing, quality assessment and delivery of the different data products that constitute the results of the population censuses conducted across the United Kingdom in 2011. It provides those interested in using census data with an introduction to the collection, processing and quality assessment of the 2011 Census, together with guidance on the various types of data resources that are available and how they can be accessed. It demonstrates how new methods and technologies, such as interactive infographics and web-based mapping, are now being used to visualise census data in new and exciting ways. Perhaps most importantly, it presents a collection of applications of census data in different social and health science research contexts that reveal key messages about the characteristics of the UK population and the ways in which society is changing. The operation of the 2011 Census and the use of its results are set in the context of census-taking around the world and its historical development in the UK over the last 200 years. The results of the UK 2011 Census are a unique and reliable source of detailed information that are immensely important for users from a wide range of public and private sector organisations, as well as those working in Population Studies, Human Geography, Migration Studies and the Social Sciences more generally.

Book Description
When it comes to immigration, the population explosion, the collapse of the family, the north-south divide, devolution, or the death of the countryside, common wisdom tells us that we are in trouble; however, this is far from the truth. In his brilliant anatomy of contemporary Britain, leading geographer Daniel Dorling dissects the nation and reveals unexpected truths about the way we live today, contrary to what you might read in the news: The human mosaic: Most children who live above the fourth floor of tower blocks in England are Black or Asian. The higher you go in a building, the darker skinned children tend to be. Relationships: The more times a person's heart is broken, the nearer they will tend to move to the sea. If you want to find a good man to marry head for the countryside. North and South: People in the south move home on average every seven years and job every eight years. This is a year faster than in the north of England, but a year slower than is usual in Scotland. Optimum population: Emmigrant nation - There are twice as many grandchildren of British-born people living over-seas as there are people living in Britain who have grandparents who were themselves born abroad. The problem now is more about getting pregnant than a population explosion and we need more immigration not less. Immigration: Muslims are far more likely to marry non-Muslims in Britain than Christians are to marry non-Christians. The elderly: Most people in Britain never live long enough to experience being burgled. In some areas you would have to live for over five hundred years to have an 'evens' chance of being a crime victim. Town and Country - divided since the enclosures: Step children are most commonly found in the most leafy of idyllic rural villages. Nuclear family homogeneity is now an inner city phenomena. Why are there no cheap homes in the countryside any more? Transport: The greatest threat to life in Britain of all those aged under 40 is the car. For adults aged over 24 they most likely die as a driver, over 15 as a passenger, and over age 4 as a pedestrian. Work: There is no need for us to work until we drop - all could retire early. Reviews for Injustice: "A geographer maps the injustices of Selfish Capitalism with scholarly detachment." --Oliver James. "Dorling provides the brain-cleaning software we need to begin creating a happier society. " --Richard Wilkinson author of The Spirit Level.
