"In this paper it is shown how new visualization techniques are being used to analyze the first results of the British 1991 Census and other large data sets." The focus is on new ways to show how localities develop over time. The author suggests that this cannot be done effectively using traditional quantitative techniques. "Pictures are needed to show how different processes occur in different places, and holistic patterns need also to be seen without generalizing out the detail. Neither traditional thematic mapping nor commercial geographic information systems can do this well. Spatial visualization is an alternative approach in which the researchers choose what they wish to see and how they wish to view it. Many problems require new methods of visualization for their exploration. A new census presents us not only with new statistics, but also with the opportunity and impetus to develop radically different ways of envisioning information to reveal more fully the human facts contained within a mass of social statistics."  相似文献

This note addresses the role of survey information and expert opinion in constructing input-output tables. In contrast to assuming polar positions between tables based on expert opinion and tables based on empirical observation, we argue that the distinction is not well-defined. We provide, as evidence, a comparison of U.S. Bureau of Economic Analysis (BEA) data on the use of commodities by industries with corresponding Bureau of the Census (BOC) Census of Manufacturers data on selected use of materials by industry (published as Census Table 7). Results show that changes in BEA data cannot be explained by corresponding changes in the Census data on which they are founded.  相似文献

This is a report on the survey conducted for the United Kingdom Census Office by the Economic and Social Research Council (ESRC) concerning the 1991 census. "The primary task was to solicit views on the priority which [academic social scientists] attached to the proposed topics to be covered by the Census and to ascertain their views on the changes in question wording which are under consideration.... Views were also sought on different methods for giving academics access to individual-level data from the 1991 Census."  相似文献

Summary An incomplete hierarchy of shopping centers has been identified for Austin, With consideration of the CBD and planned ribbon developments, a complete hierarchy might well be postulated. The depleted population of lowest level centers has been noted and shown to be not incompatible with the other findings.However, some systematic elements have been deduced from the spacing of these centers. With a map transformation, a greater regularity may be found than had been detected here. But the actual distribution has been explained in terms of uneven densities of opportunities since the hierarchical requirement of central place theory had already been fulfilled. Topological variance in such a map transformation as has been suggested may considerably complicate a solution which could adequately account for the distribution of such transport oriented service centers as shopping centers. Further research on this data with such reordered space, using entropic analysis and evaluating the information contained in several distributions under different transformations might prove interesting. More complete data on shopping centers, particularly opening dates, and for defunct centers, store types and closing dates would aid the evaluation of the validity of the deductions made here.Donald Wade Jones is a Graduate Student, Department of Geography, University of Chicago and was previously a Graduate Student in the Department of Geography, University of Texas, at Austin.

"An administrative register, the National Health Service Central Register (NHSCR), is used by the Census Office (OPCS) to produce counts of NHS patients re-registering in different Family Health Service Authorities (FHSAs) in England and Wales. These movement data can be used to establish how unique or typical the migration occurring in the year prior to the Census was in relation to that for the whole decade. This paper examines national, regional and local examples of the information that can be extracted from a database system called TIMMIG that provides access to an NHSCR migration time series and a parallel series of mid-year population estimates. In advance of the publication of Special Migration Statistics, a preliminary comparison is made between the levels of in-migration to FHSA areas recorded in the NHSCR and in the 1991 Census."  相似文献
