Short-term migration, that is stays of less than 12 months, has received particular attention recently from both national and local level users of population statistics. This interest is part of the wider interest shown in increasing levels of long-term migration statistics in recent years. This article is an initial assessment by ONS of the potential to produce short-term migration estimates for England and Wales, and the challenges faced in doing so. Central to these challenges is the question of how short-term migration should be defined. In addition, illustrative estimates of short-term migration based on the International Passenger Survey (IPS) are provided. These illustrative estimates, along with associated standard errors, are provided at both national and regional levels using a number of definitional bases.  相似文献

This comparative study explores the use of the Cohort Component Method (CCM) to produce national level population estimates. This method is used annually to calculate mid-year population estimates for England and Wales by the Office for National Statistics (ONS). Initially the article considers recent population change in England and Wales, with particular emphasis on the growing importance and challenges faced by migration estimation. Comparisons are then made between how population estimates are produced in England and Wales and other countries, with a particular focus on differences in the way the CCM is applied. Recent changes in methods used to estimate population are then reviewed along with a discussion of alternative approaches such as those described in academic literature.  相似文献

The Office for National Statistics (ONS) has set up a project to investigate the feasibility of producing postcensal small area population estimates on a nationally consistent basis for England and Wales. Following on from earlier investigations to identify potential data sources and methods, ward and Super Output Area population estimates have been released as 'experimental statistics'. This article covers the methodology used to produce these estimates, feedback from user consultation with the initial estimates released at ward level, summary statistics on the population estimates for mid-2001 to mid-2003, and future developments for small area population estimates.  相似文献

The Office for National Statistics (ONS) is planning a major Census field test in 2007. It will form part of the planning and testing programme leading to up the next Census of Population for England and Wales in 2011, which will also include a Rehearsal in 2009. The 2007 Test will be a large-scale test in five local authority (LA) areas selected to reflect a range of field conditions, covering some 100,000 households in total. Within England the Test will cover parts of Bath and North East Somerset, Camden, Liverpool and Stoke-on-Trent. In Wales the Test will take place in Carmarthenshire. The selected LAs have been chosen to provide a varied cross-section of the population and types of housing that would be covered in a full census. This article sets out the main aims for the Test and describes the design and location of the sampled areas and the basis for their selection. It goes on to detail the ways (previously reported in Population Trend 1251) in which the ONS Census team and the LAs involved are working in partnership in planning the census enumeration with the long-term view of improving overall census coverage and user confidence in the results. The article notes that decisions on the topics to be covered in the 2007 Test have only recently been decided, and concludes with an overview of the qustions to be included in the 2007 Test questionnaire.  相似文献

This article provides a summary of a review of the uses made of population and household statistics across government in England and Wales, setting out the policy and statistical impacts of demographic change. It looks at the broad span of government uses of population and household statistics--and what these uses imply for the qualities inherent in these statistics. The article considers alternative population definitions and refers to several ongoing projects that are aiming to enhance demographic statistics in England and Wales. Following an analysis of the key issues relating to the implementation of an improved statistical service, a series of action points for ONS emerging from the review is set out.  相似文献

This article presents information discussed at the recent regional seminars on population statistics. It describes a new data source for estimating internal migration between local and health authorities in England and Wales, discusses the way that the data have been collected and processed, and how limitations in the raw data have been addressed. It then goes on to explain the way that the new internal migration estimates have been used in the calculation of population estimates for local and health authorities. This is a change to the method of estimating migration in the calculation of population estimates.  相似文献

The Office for National Statistics (ONS) has set up a project to investigate the feasibility of producing postcensal small area population estimates on a nationally consistent basis for England and Wales. Research has taken place to identify datasets that could potentially be used within a method to produce small area population estimates. Following an evaluation of a number of different administrative datasets, the most suitable have been short-listed for further consideration. This article presents the findings of the evaluation, based on 2001 data, and summarises the characteristics of these short-listed data sources. This article does not cover the methods that are being evaluated as part of the feasibility assessment.  相似文献

Among datasets available for fertility research in England and Wales, the Office for National Statistics (ONS) Longitudinal Study (LS) is unique in its construction and scale. The large number of individuals who are part of the study means that it is an important dataset for estimating fertility trends in England and Wales by age and parity. This article uses the LS to estimate age-specific fertility rates (ASFRs) for England and Wales between 1991 and 2001. This necessitates great care to ensure that the exposure to risk of birth for female LS members is fully understood. To achieve this, two forms of residential history are defined - consistent cases where the residential information for the LS member is potentially complete for the whole decade and inconsistent cases where there is certainly some form of incompleteness in the residence information. By considering 'all consistent cases', that is both the continuously resident plus those who are not continuously resident but appear to have a complete residential history, we obtain ASFRs which are slightly lower than official statistics figures, but closer to these official figures than ASFRs produced when restricting the sample to LS members who remain continuously resident between 1991 and 2001. The fertility of those consistent cases who are not continuously resident is substantially higher than the rates of continuously resident cases.  相似文献

This article outlines the Office for National Statistics' strategic review process for the best way of meeting users' future requirements for information that has traditionally been collected by taking a census. It reports on a possible design for such a census in 2011 but also considers alternative approaches to collecting comparable information. The work described in this article is being undertaken within ONS and relates essentially to research on the census in England and Wales only. The General Register Office for Scotland and the Northern Ireland Statistics and Research Agency are, however, carrying out similar reviews.  相似文献

This article uses data for members of the ONS Longitudinal Study (LS) from both Census 2001 enumeration and patient registrations "frozen" on census day 2001 from the National Health Service Central Register (NHSCR) to examine potential sources of difference in area of usual residence.Overall 95.7 per cent of ONS LS members enumerated at census resided in the same area as recorded on the NHSCR data. Where areas differed, or the ONS LS member was not on the NHSCR on census day, subsequent NHSCR records were examined. Records flagged on the NHSCR as ONS LS members in England and Wales on census day but with no census record were also investigated.  相似文献

Over the last three decades fertility in Scotland, as measured by the total fertility rate (TFR), has moved from being higher than in England and Wales, to being lower. The annual number of births in Scotland has declined so that in the mid-1990s low fertility became the main driver of the overall population decline that Scotland has been experiencing since 1974. Analysis of fertility by birth order is instrumental in gaining an understanding of past and future fertility trends. Until the rise in births outside marriage in the 1980s data from registration could be used as a proxy for true birth order. However, because birth order is not collected for births outside marriage true birth order now has to be estimated. This article presents the first official estimates of true birth order for Scotland. The construction of these estimates based on a modified version of the method used for England and Wales is discussed. This article also presents analysis relating births by true birth order estimate to the population of women by parity on a cohort basis, and makes comparisons with England and Wales.  相似文献

This article sets out the proposed design for a 2011 Census in England and Wales, as part of the ONS's proposed future population statistics system. The design draws on experiences from the 2001 Census and changes in available technology, and takes account of the many comments received from respondents to a Discussion Paper published in October 2003 and of views expressed at a joint ONS/RSS Conference on 11-12 November 2003. The article highlights the statistical and operational strategic aims for the 2011 Census, the major changes proposed from the 2001 approach, and gives an indication of the benefits and risks. It is important to note that this design remains a proposal at present, the elements of which will be subject to further research building on comments received during consultation and a detailed testing programme over the coming years.  相似文献

This article describes the improvements in the way that ONS will be allocating births and deaths data to administrative and health areas in England and Wales, beginning with data for 2001. Births and deaths registered in 2000 are used to examine the differences in area allocations at ward, local authority and health authority levels, which this change will introduce. Differences in the geographical characteristics of births and deaths are also described.  相似文献

This article examines geographic variations in conceptions to women aged under 18. It presents data on conception rates and the percentage leading to abortion for the three countries of Great Britain, the Government Office Regions of England and local authorities within Great Britain. It provides an overview of variations between areas at each of the three geographic levels and examines whether this variation is associated with the social and demographic characteristics of local authority areas. This article is the first occasion on which conception rates for Scotland have been published on a comparable basis to England and Wales and also the first use of the revised ONS classification to examine conceptions to women aged under 18.  相似文献

This article describes, and provides some initial analysis of, the experimental population estimates by ethnic group for areas within England published by the Office for National Statistics (ONS) in January 2006. The article considers growth and the population structure of each of the ethnic groups identified in the 2001 Census; subnational patterns of change; population turnover; and measures of diversity and segregation, and also provides a comparison of the estimates and corresponding sample-based estimates from the Labour Force Survey.  相似文献

Changes in the ages at which women give birth to their children mean that fertility measured at a particular point in time (period) may not be a good representation of the ultimate fertility of those women. The common measure of period fertility is the total fertility rate, which in 2001 has fallen to the lowest level since records began in England and Wales. This article presents various methods that have been proposed to adjust period fertility data to take account of changes in the timing of childbearing, applied to England and Wales data. The article concludes that while these adjustment methods provide useful insights, for example, that the total fertility rate has underestimated period quantum fertility since the 1970s, the measures produced are difficult to interpret. This is in part because the concept they are trying to measure, period quantum is itself imprecise. The adjustments do not necessarily provide a reliable indicator of underlying cohort fertility.  相似文献

This article describes the most recent process of projecting population at the subnational level in England. It briefly explains the reasons why projecting population at the subnational level is important, describes the model and how it was used to produce the latest set of long-term subnational population projections in England published by the Office for National Statistics (ONS) in 1998. The article then discusses how the model may be applied to answer various 'what-if' questions about future population.  相似文献

The population of England and Wales is becoming older. This poses an increasing demand for detailed data on the size an trends of the population at the oldes ages. Using the recently released Offic for National Statistics estimates of th population aged 90 and over in England and Wales, this article shows trends in the population of the oldest old and demographic causes of the rapid increase in centenarians during the twentieth century. It also presents further validation of the ON estimates of the oldest old with estimat from other data sources.  相似文献
