Central registers and administrative data as data source in the Norwegian population census.

"The purpose of this paper is to give a description of the use of central registers and administrative data in the [Norwegian] Population Census 1980, and describe a supplementary survey to the 1980 census which is based on administrative data only. The paper will deal with some methodological problems concerning statistical use of administrative data. An annex to the paper gives a further description of the Population census." (summary in FRE)

Evaluating the Slavonian census of 1698. Part I: structure and meaning.

"Microsimulation, other demographic tools, and evidence of history and ethnography are used to evaluate an important 17th century household census [in Slavonia, which is modern Croatia]. Linguistic, ethnographic, and internal evidence allow adjustment of anomalies in census categories. Microsimulation based on historically and ethnographically plausible rates and household formation scenarios produces simulated households in accord with those of the adjusted census. Results permit estimation of the true population of the region, of the kinship and age composition of households under frontier conditions, and the probable future composition of households as the frontier stabilized and land shortage began to exert pressure for greater density and household complexity. Part I concentrates on historical, ethnographic, and linguistic evidence." (SUMMARY IN FRE)

Making sense of Census data: a components analysis of employment change among indigenous Australians.

"The 1996 Census count of indigenous Australians included a substantial number of individuals who were not recorded as indigenous by the previous census. This paper considers the implications of this for interpreting change in employment numbers. Two adjustments are made to employment change data. First, reverse survival of the 1996 population is applied to reconstruct 1991 employment figures. Second, administrative data are used to discount employment generated by participation in labour market programs. The effect is to substantially deflate the strong intercensal employment growth apparent from census counts with the conclusion that the rate of indigenous employment in the mainstream labour market has fallen."

Understanding the 1996 census migration data.

"The Australian Census provides two approaches to measuring migration: indicators which distinguish movers from non-movers, and a geographic classification which identifies each person's usual residence on census night, and their usual address one year and five years previously. Although these data represent a rich source of information, they contain several traps for the unwary. We show that differences in the variables and classifications used can result in marked variations in the apparent intensity and patterns of migration. The questionnaire and processing methodology used in the 1996 Census also resulted in a number of inconsistencies between the migration indicators and the usual address information. We examine the magnitude and source of these anomalies, assess their implications and propose a partial solution."

Ecological fallacies and the analysis of areal census data.

The author examines problems related to the fact that in many countries, census data are only reported for areal units and not at the individual level. Attention is paid to the question of ecological fallacy problems that arise from this situation. Data from a 10 percent sample of the United Kingdom population and individual census data from Italy are used to illustrate the problem. "It is concluded that ecological fallacy effects are endemic to areal census data, although their magnitude is perhaps not as large as might have been expected. The principal difficulty is that there is at present no way of predicting in advance the degree of severity likely to be associated with particular variables and particular techniques. Finally, a suggestion is made concerning how the potentially serious practical consequences can be reduced."

Quantos somos? The second national population census of Mozambique.

"Between 1 and 15 of August [1997], Mozambique had its second country-wide population census. This briefing will outline how the census ran--an operation of considerable scale in an extremely poor and war-damaged country--and will also raise some broader questions which relate the census to Mozambique's contemporary politics."

Using remotely sensed data for census surveys and population estimation in developing countries: examples from Nigeria.

"Using examples from Nigeria, this paper demonstrates how remotely sensed data can be used to acquire some of the basic data requirements for census surveys and to estimate population. The result obtained shows that visual identification of settlements on Landsat MSS and TM is more accurate and economical than equivalent digital classification techniques. Black and white aerial photographs were used to estimate the population of a model town and to establish EAs [enumeration areas]. The population estimation method employed can be used to obtain intercensal population estimates for the rapidly growing central places, while the established EAs for the study area have created a permanent base for future census surveys and census cross-validation, population estimation and other social surveys."

The tragedy of the census.

The author discusses the debate on how to reduce the undercount error in the 2000 U.S. census. He reviews the history of the census, and considers the impact of the "opposing ¿interest groups' represented in Congress and elsewhere debating methodological issues that can affect the distribution of census-allocated resources [who] tend to favor methodological choices that will increase their resources."

Census-based information systems for ethnic groups: a study of Leeds and Bradford.

"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 ethnic groups in order to distinguish real differences from apparent ones. The attempt is not fully successful, but it does provide clear pointers on how to proceed further in research on the ethnic spatial mosaics that [British] cities now are."

Classification by race and Spanish origin in the 1980 census and its impact on white and nonwhite rates.

A basic change concerning the racial classification of persons of Spanish origin used in the 1980 U.S. census is examined for its impact on white and nonwhite population counts, particularly in urban areas. "Arrest rates by race for central city Phoenix together with 1980 census data by race and ethnicity for Phoenix and 11 other central cities are used to illustrate the substantive effect of changes in the white and 'other race' counts produced by this change in procedure." The authors consider "remedies for the problems faced by those using published census data..., and one possibility for creating comparable rates is presented. Closely related complications created by the failure of the Office of Management and Budget to arrive at a single, logical statistical standard for the classification of U.S. residents by race and ethnicity are also identified."

[The processing of population censuses in Latin America for the 1990 decade: a view into the future].

"The purpose of this paper is to define the data processing methods that will be used in the 1990 population censuses in the different countries of Latin America.... The countries are divided into four groups, and procedures and methodologies are suggested for each of the main eight stages of a census processing." In general, microcomputers are recommended at the initial stages of processing census data, with the exception of data entry for populations over 10 million, for which the utilization of optical readers is recommended. For the final stages of consistency, tabulation, and data base management, microcomputers are recommended only for populations less than a million. (SUMMARY IN ENG)

A study of digit preference and quality of age data in Turkish censuses.

The authors study digit preference and the quality of age data in the 1945, 1955, and 1970 censuses of Turkey. "Using the age distributions in successive censuses and particular cohort groups as well as the analysis of stable population, severe misreporting of certain ages was found. The...age data seem to be influenced substantially by both response errors and coverage errors....[and] show heaping at ages ending in zero and five years. The pattern of heaping is pronounced from age 20 onwards and this is true both for males and females. Various analyses showed clear evidence of heaping in all the three censuses at the age group 40-44 years irrespective of sex. The magnitude of digit preference bias seems to be reducing with the passage of time. This is especially true in the case of females. The possibility of increased female literacy as a factor underlying this reduction is pointed out. Other implications of the results are discussed." (SUMMARY IN FRE AND ITA)

Recent work with microcomputers for census processing in developing countries.

The use of microcomputers to process census data in developing countries is discussed. Specifically, the authors describe the Integrated Microcomputer Processing System (IMPS) developed by the U.S. Bureau of the Census and focus "on the recent experience of Burkina Faso and Senegal in using microcomputers. A summary is given of the use of IMPS by an increasing number of countries. Additionally, this paper describes the latest enhancements and future plans for IMPS. It concludes with some thoughts on the use of microcomputers in the areas of data collection and processing, as well as in the use and dissemination of census data."

[Modeling matching error and its effect on estimates of census coverage error].

"In this paper, we propose a model for investigating the effect of matching error on the estimators of census undercount and illustrate its use for the 1990 [U.S.] census undercount evaluation program. The mean square error [MSE] of the dual system estimator is derived under the proposed model and the components of MSE arising from matching error are defined and explained. Under the assumed model, the effect of matching error on the MSE of the estimator of census undercount is investigated. Finally, a methodology for employing the model for the optimal design of matching error evaluation studies will be illustrated and the form of the estimators will be given."

[Correcting for an undercount. The case of the U.S. census].

Undercount problems in the U.S. census are outlined, and methods to correct them are described. "Methods tested in the last decade appeared very promising, but a political decision was made not to adjust the census. That decision has now been repealed and the 1990 U.S. Census may be the first to reflect an adjustment for the undercount." (SUMMARY IN ENG AND SPA)

Which countries will follow the Scandinavian lead in taking a register-based census of population?

"During the past twenty years Scandinavian countries have made changes in the methods of taking population and housing censuses that are more fundamental than any seen since modern census methods were first introduced two hundred years ago. These countries extract their census data in part or in whole from administrative registers. If other countries in Western Europe were to adopt this approach, most of them would have to make major improvements to their administrative records. But the primary reasons for making such improvements are concerned with administration and policy rather than statistics, namely, the need to secure a more effective and fairer system of public administration and to enable governments to exercise a wider range of policy options."

Computer systems to support census geography.

The development of computer systems that support the geography of the census in Canada is described. The authors "present proposals for the 1991 Census that increase the level of automation, whether the geography changes or not. In addition, opportunities for change and improvement, should the geography change, are outlined. To minimize the risks involved, it is important to give these different proposals serious consideration early in the planning of a census."
