基于行政记录人口普查方法的国际比较

开展基于行政记录的人口普查被视为有效破解传统人口普查难题的途径之一,亦是顺应大数据时代充分挖掘人口行政记录资源的必然之选。本文较系统地阐述了基于行政记录人口普查方法的基本框架,尝试对“完全模式”人口普查和“组合模式”人口普查的实施步骤进行解析。基于此,本文选择芬兰、奥地利、瑞士、荷兰四个国家,分普查基本情况、行政记录类型选择和基本记录库形成、已存在统计记录系统基本结构、专门组织的抽样调查设计、不同系统间的链接途径、新人口统计信息质量评估方法等六个维度,对实施基于行政记录的人口普查方法进行了国家比较。     

An alternative view of the 2001 census and future census taking

Summary.  The 2001 census in the UK asked for a return of people 'usually living at this address'. But this phrase is fuzzy and may have led to undercount. In addition, analysis of the sex ratios in the 2001 census of England and Wales points to a sex bias in the adjustments for net undercount—too few males in relation to females. The Office for National Statistics's abandonment of the method of demographic analysis for the population of working ages has allowed these biases to creep in. The paper presents a demographic account to check on the plausibility of census results. The need to revise preliminary estimates of the national population over a period of years following census day—as experienced in North America and now in the UK—calls into question the feasibility of a one-number census. Looking to the future, the environment for taking a reliable census by conventional methods is deteriorating. The UK Government's proposals for a population register open up the possibility of a Nordic-style administrative record census in the longer term.     

Combining census and registration data to estimate detailed elderly migration flows in England and Wales

Summary.  A log-linear model is developed to estimate detailed elderly migration flows by combining data from the 2001 UK census and National Health Services patient register. After showing that the census and National Health Service migration flows can be reasonably combined, elderly migration flows between groupings of local authority districts by age, sex and health status for the 2000–2001 and 2003–2004 periods are estimated and then analysed to show how the patterns have changed. By combining registration data with census data, we can provide recent estimates of detailed elderly migration flows, which can be used for improvements in social planning or policy.     

The case for samples of anonymized records from the 1991 census

"The census of population represents a rich source of social data. Other countries have released samples of anonymized records from their censuses to the research community for secondary analysis. So far this has not been done in Britain. The areas of research which might be expected to benefit from such microdata are outlined, and support is drawn from considering experience overseas. However, it is essential to protect the confidentiality of the data. The paper therefore considers the risks, both real and perceived, of identification of individuals from census microdata. The conclusion of the paper is that the potential benefits from census microdata are large and that the risks in terms of disclosure are very small. The authors therefore argue that the Office of Population Censuses and Surveys and the General Register Office of Scotland should release samples of anonymized records from the 1991 census for secondary analysis."     

First German register based census in 2011

Summary The last censuses in Germany were accomplished in 1987 (former federal states) and 1981 (new federal states), respectively. Germany was the only country which did not participate in the EU-wide census in 2000. A traditional census was not feasible on political scale due to high costs and low acceptance by the population. Complete, precise and actual statistical registers as a condition for a register based census, are non-existent in Germany. Official statisticians developed a model for a register based census with interviewer-based surveys kept to a minimum. As the basic conditions were not favourable the model became very complex and many methods and procedures had to be developed for the special case of German registers. Core model elements were tested in a census test, such as quality of registers (e. g. municipal population registers, registers of the federal labour agency) and practicability of procedures (e. g. merging of registers, household generation). The test result was that a register based census is possible but much development work still has to be done, as the registers do not have an acceptable quality yet. Additional interviewer based surveys will be necessary for correction of errors of the register and survey of additional variables. This is also true if measures to improve municipal population registers, e. g. a feedback procedure and a nationwide tax number are taken into account. So these measures will not substitute the additional interviewer based surveys. Provided that the essential investments in development and preparation will be performed, Germany could participate in the 2011 EU-census-round with a register based census at a fraction of the cost of a traditional census. Finally, the census 2011 will show the real quality of the registers, how the model will work throughout the country and which measures have to be taken before the following census.

Zusammenfassung In Deutschland wurde die letzte Volksz?hlung 1987 (Alte Bundesl?nder) bzw. 1981 (Neue Bundesl?nder) durchgeführt. An dem EU-weiten Zensus um das Jahr 2000 beteiligte sich Deutschland als einziger EU-Staat nicht, da ein herk?mmlicher Zensus aus Kosten- und Akzeptanzgründen politisch nicht durchsetzbar war. Die Voraussetzungen für einen Registerzensus, d. h. Statistikregister, die alle ben?tigten Merkmale mit hinreichender Genauigkeit und Aktualit?t enthalten, waren und sind nicht vorhanden. Amtliche Statistiker entwickelten ein Modell für einen registergestützten Zensus mit einem m?glichst geringen Anteil an prim?rstatistischen Erhebungen. Aufgrund der für einen Zensus auf Basis von Registern ungünstigen Rahmenbedingungen wurde dieses Modell relativ komplex und in vielen Bereichen statistisches Neuland betreten. Wesentliche Elemente des Modells wurden in einem sog. Zensustest überprüft. Getestet wurden insbesondere die Qualit?t und Aktualit?t vorhandener Register, wie Melderegister und Dateien der Bundesagentur für Arbeit, sowie die Eignung und Wirksamkeit der Verfahren, wie Zusammenführungen der Daten aus verschiedenen Quellen und Haushaltegenerierung. Die Tests best?tigten die Machbarkeit des Zensusmodells, zeigten aber gleichzeitig, dass noch umfangreiche Entwicklungsarbeiten erforderlich sind und dass die Register noch keine Qualit?t aufweisen, die einen Verzicht auf prim?rstatistische Erhebungen zur Korrektur und Erg?nzung der Registerergebnisse zulassen. Dies gilt auch unter Berücksichtigung der in den n?chsten Jahren vorgesehenen Ma?nahmen zur Verbesserung der Qualit?t der Melderegister, wie die Einführung eines elektronischen Rückmeldeverfahrens oder die Erg?nzung der Melderegister um eine bundeseinheitliche Steuernummer für jede Person. Soweit in den n?chsten Jahren die erforderlichen Investitionen in Entwicklung und Vorbereitung eines registergestützten Zensus get?tigt werden, k?nnte in Deutschland im Rahmen der n?chsten EU-Zensusrunde ein solcher Zensus im Jahre 2011 zu einem Bruchteil der Kosten eines herk?mmlichen Zensus durchgeführt werden. Erst mit diesem Zensus k?nnte dann letztlich festgestellt werden, welche Qualit?t die Register zu diesem Zeitpunkt aufweisen, wie sich das Modell eines registergestützten Zensus (fl?chendeckend) in der Praxis bew?hrt und welche Ma?nahmen für darauf folgende Zensen in Angriff genommen werden müssen.

     

Suggestions for the application of advanced technology in Canadian collection operations

This study is concerned with technical advances that could be applied to data collection in the course of the 1990 Canadian census. Consideration is given both to the advantages and disadvantages of such changes. Topics covered include privacy, costs, and relations with users of census data.     

Census data issues for epidemiology and health risk assessment: experiences from the Small Area Health Statistics Unit

Summary.  Census data are vital components of epidemiological studies, but the issues that are involved in using these data in such studies are often not fully appreciated. The paper describes some of the problems and uncertainties that arise, and some of the approaches that can be used to address them, based on experience in the Small Area Health Statistics Unit at Imperial College London. Issues considered include the geography of census data (zone design systems, recasting and the role of postcodes), temporal aspects of census data (especially in relation to migration and population change) and information content (especially in relation to characterization of socio-economic status). In the light of these issues, opportunities to improve the resolution and utility of census data for epidemiological studies are discussed.     

简析身份证号信息在人口普查中的作用

人口普查是世界各国广泛采用的搜集人口资料的一种科学方法,它为国家制定政策提供权威的人口数据,但是,历届人口普查都面临着重报、漏报等严重问题。身份证号码虽然仅有18位,但是信息丰富,而且每位公民的号码都是唯一的,不可重复的。在普查中询问身份证号码,可以取代普查表中的多个问题,可以避免重报、漏报问题,还可以通过身份证号码中地址码与问卷登记地的地址码相比较确定流动人口。通过对"五普"和"六普"数据的分析,我们发现,在以后的人口普查中通过加入身份证号码的询问可以帮助提高普查数据的质量。     

A methodological strategy for a one-number census in the UK

As a result of lessons learnt from the 1991 census, a research programme was set up to seek improvements in census methodology. Underenumeration has been placed top of the agenda in this programme, and every effort is being made to achieve as high a coverage as possible in the 2001 census. In recognition, however, that 100% coverage will never be achieved, the one-number census (ONC) project was established to measure the degree of underenumeration in the 2001 census and, if possible, to adjust fully the outputs from the census for that undercount. A key component of this adjustment process is a census coverage survey (CCS). This paper presents an overview of the ONC project, focusing on the design and analysis methodology for the CCS. It also presents results that allow the reader to evaluate the robustness of this methodology.     

The USA's bicentennial census: new directions for methodology in 1990

"Planning is under way for the U.S.A. bicentennial census in 1990. The U.S. Census Bureau sponsored a study panel under the U.S. Committee on National Statistics to consider key aspects of methodology for the census and to recommend priority areas for research and testing. The recommendations of the Panel on Decennial Census Methodology, which are summarized in this paper, cover four main topics: adjustment of the census counts for coverage errors, methods of coverage evaluation, uses of sampling in obtaining the count, and uses of administrative records in improving the quality of selected content items."     

Frame Correction Modelling with Applications to the German Register‐Assisted Census 2011

Frame corrections have been studied in census applications for a long time. One very promising method is dual system estimation, which is based on capture–recapture models. These methods have been applied recently in the USA, England, Israel and Switzerland. In order to gain information on subgroups of the population, structure preserving estimators can be applied [i.e. structure preserving estimation (SPREE) and generalized SPREE]. The present paper extends the SPREE approach with an alternative distance function, the chi‐square. The new method has shown improved estimates in our application with very small domains. A comparative study based on a large‐scale Monte Carlo simulation elaborates on advantages and disadvantages of the estimators in the context of the German register‐assisted Census 2011.     

Census data quality--a user's view

"This paper presents the perspective of a major user of both decennial and economic [U.S.] census data. It illustrates how these data are used as a framework for commercial marketing research surveys that measure television audiences and sales of consumer goods through retail stores, drawing on Nielsen's own experience in data collection and evaluation. It reviews Nielsen's analyses of census data quality based, in part, on actual field evaluation of census results. Finally, it suggests ways that data quality might be evaluated and improved to enhance the usefulness of these census programs."

Perturbed robust linear estimating equations for confidentiality protection in remote analysis

National statistical agencies and other data custodians collect and hold a vast amount of survey and census data, containing information vital for research and policy analysis. However, the problem of allowing analysis of these data, while protecting respondent confidentiality, has proved challenging to address. In this paper we will focus on the remote analysis approach, under which a confidential dataset is held in a secure environment under the direct control of the data custodian agency. A computer system within the secure environment accepts a query from an analyst, runs it on the data, then returns the results to the analyst. In particular, the analyst does not have direct access to the data at all, and cannot view any microdata records. We further focus on the fitting of linear regression models to confidential data in the presence of outliers and influential points, such as are often present in business data. We propose a new method for protecting confidentiality in linear regression via a remote analysis system, that provides additional confidentiality protection for outliers and influential points in the data. The method we describe in this paper was designed for the prototype DataAnalyser system developed by the Australian Bureau of Statistics, however the method would be suitable for similar remote analysis systems.

Some unique characteristics of the demographic situation in Russia

The authors briefly describe the demographic situation in the Russian Soviet Federated Socialist Republic, using data from the 1989 census and current demographic research. Changes in the birth rate and population growth are examined, and migration flows in the various regions of the republic are compared. Factors affecting low birth rates are analyzed, and trends in marriage, divorce, mortality, and life expectancy are explored.     

Stochastic models of geriatric patient bed occupancy behaviour

This paper considers a census approach to the modelling of the time that geriatric patients spend in hospital and subsequently in the community by using a stochastic compartmental Markov model. A selection process is developed using maximum likelihood estimation to fit the model to daily census data on the duration spent in the hospital or the community. Census data are used as they are easy to collect and therefore maximize the usability of the model. The model is fitted to an extensive 16-year data-set and shown to provide realistic estimates of movements of patients by using only a single day's census result.     

How increased automation will improve the 1990 census of population and housing of the United States

"The U.S. Bureau of the Census will increase significantly the automation of operations for the 1990 Census of Population and Housing, thus eliminating or reducing many of the labor-intensive clerical operations of past censuses and contributing to the speedier release of data products. An automated address control file will permit the computer to monitor the enumeration status of an address. The automated address file will also make it possible to begin electronic data processing concurrently with data collection, and, thus, 5-7 months earlier than for the 1980 Census. An automated geographic support system will assure consistency between various census geographic products, and computer-generated maps will be possible. Other areas where automation will be introduced or increased are questionnaire editing, coding of written entries on questionnaires, and reporting of progress and cost by field offices."     

Dependence in the 2001 one-number census project

Summary.  The one-number census approach was developed by the Office for National Statistics to adjust the counts from the 2001 census of England and Wales for underenumeration. The method is underpinned by an assumption of independence between the count of the population that was given by the 2001 census and the count that was given by the Census Coverage Survey. Some dependence was, however, detected, and the paper describes the strategy that was used to measure dependence and to adjust the 2001 census population estimates.
