The Estimation of Population Microdata by Using Data from Small Area Statistics and Samples of Anonymised Records
Census data can be represented both as lists and as tabulations of household/individual attributes. List representation of Census data offers greater flexibility, as the exploration of interrelationships between population characteristics is limited only by the quality and scope of the data collected. Unfortunately, the released lists of household/individual attributes (Samples of Anonymised Records, SARs) are spatially referenced only to areas (…
What Do You Want from the 2001 Census? Results of an ESRC/Jisc Survey of User Views
The author describes the results of a survey of user views about the next Census of Population in the United Kingdom, to be held in 2001. Some 140 respondents reported their views, which included strong support for a question on income, endorsement of the new one number census methodology and support for postcode-based outputs. The author sets these views in the context of the Census Development Programme being carried out by the UK Census Office…
Methods for estimating missing data on migrants in the 1991 British census
This paper discusses the use of suppression to protect data in the Special Migration Statistics, a dataset produced from the 1991 Census, and argues that this procedure prevents accurate analysis of the data. A computer program is described that uses a series of methods to "recover' data which were suppressed, and to estimate those parts of the data which cannot be recovered. A process termed logical data patching is used to recover data, while a…
Methods for estimating missing data on migrants in the 1991 British census
This paper discusses the use of suppression to protect data in the Special Migration Statistics, a dataset produced from the 1991 [British] Census, and argues that this procedure prevents accurate analysis of the data. A computer program is described that uses a series of methods to ¿recover' data which were suppressed, and to estimate those parts of the data which cannot be recovered.... The program has been used to recover and estimate data suc…
Research Policy and Review 30. How to Add Value to Migration Data from the 1991 Census
The form in which migration information is likely to be provided from the 1991 Census is reviewed, and suggestions are made about how this provision can be improved for the academic research community, building on the experience of the 1981 Census. The recommendations add considerable value to the information at relatively low cost

Projections of the Residential Distribution of an Ethnic Group
The population originating in India but living in Bradford and its offspring grew by about 60% over the decade 1971 to 1981 and underwent significant redistribution. An attempt is made to assess how the growth and redistribution patterns of the Indian community are likely to change over the next thirty years, as a result of declining mortality and fertility, of directly observed migration patterns, and of the lessening of migration flows from out…

Census-Based Information Systems for Ethnic Groups
In this paper are explored the problems involved in using Census data as a guide to the evolving ethnic geography of British cities. The relationship between the concept of ethnicity and Census questions on place of birth is traced. The country-of-birth statistics for Small Areas from the 1971 and 1981 Censuses are employed in an attempt to ascertain the influence of technical specifications on the measurement of the residential segregation of et…
Multiregional Mathematical Demography
People live in many regions and move between those regions over time. These facts have been incorporated into demographic analysis via the subfield of multiregional mathematical demography. In this paper the author reviews themes in that subfield over the past two decades and discusses current issues that have yet to be resolved
Computer Program 3
The program ABM makes estimates of population accounts for multiregional systems for past or future periods of time. The population accounts can be prepared for the whole or aggregate population, or sex disaggregated populations, or age disaggregated populations, or age and sex disaggregated populations. Population accounts contain data on the populations of the regions being studied and the components that change those populations from both a mu…
Multistate Demographic Accounts
Accounting frameworks developed in the field of economics are applied to the problem of measuring changes-in-state of populations. Examples of accounts in the educational sector, in the job market, and in a regional system are described. Proper estimation of multistate demographic accounts involves attention to data sources, much initial estimation of variables, construction of a model to estimate missing items, and use of the possible constraint…
Spatial Population Analysis
Increment—Decrement Life Tables
The paper examines the problem of the estimation of the correct probabilities needed as input to a multiregional life table. A variety of alternative methods are examined by use of an expanded notation and a hypothetical test case. This theoretical investigation suggests that methods proposed by previous researchers are in error and an alternative method is proposed. However, this error is likely to be small in cases where the probabilities of tr…

The Measurement of Migration, from Census Data and other Sources
In the first part of the paper a general classification of migration measures is introduced. The rates corresponding to these measures are defined together with the associated populations at risk. A particular problem in migration analysis is then tackled. The questions asked in the British censuses of 1966 and 1971 about migration generate tabulations of migrants over the one year, and over the five years, preceding the census date. It is often …
A comparison of available models of population change
Rees P. H. and Wilson A. G. (1974) A comparison of available models of population change, Reg. Studies 9, 39–61. A hypothetical example and a common algebraic notation are employed in this paper to facilitate a systematic comparison of available models of population growth processes. The models reviewed are the cohort survival model (in “closed system” Leslie form, single region/components form, and in Rogers' multi-regional form), a projection m…
Accounts and Models for Spatial Demographic Analysis 3
The paper begins by distinguishing, with the aid of the Lexis diagram that plots age against time, three kinds of demographic rate: age-group rates, period rates, and life-table rates. There are single-region and multiregion versions of those rates. In order to measure multiregional life-table rates, life-table accounts are developed together with an accounts based model that estimates the full accounts matrix from available data. These multiregi…
Accounts and Models for Spatial Demographic Analysis 2
In an earlier paper, methods were presented for the construction of accounts and models for spatial demographic analysis. In this paper we show how these methods can be extended to deal with age-sex disaggregated populations. At the outset a new notation is introduced which facilitates disaggregation. The accounts are then defined and the basic accounting equations constructed. The appropriate rates and 'at-risk' populations are introduced as a p…
A Revised Notation for Spatial Demographic Accounts and Models
A revised notation is developed in which the accounting and model relationships that characterize multiregional population systems can be expressed. The variable K represents population as a stock, as a flow, and as an event count. People move from one state and location to another state and location over time. A special set of location-state labels for variable K describe the transitions possible. The hope is expressed that the notation will con…
Accounts and Models for Spatial Demographic Analysis I
This paper presents accounts and models which can be used for spatial demographic analysis. It is shown that in any time period there are sixteen different kinds of demographic flows for a two region system. These flows can be represented in an accounting table. Some of the minor flows, involving double or triple demographic events such as a birth followed by a migration, cannot be measured directly from data, and an iterative scheme is offered f…
