Population density change and concentration in Great Britain 1971 1981 and 1991.

The purpose of this study is to describe how the local areas in which people live in Britain have changed over the last two decades in the most simple way--through their population density. This has been done for a number of reasons. Firstly basic changes in the distribution of the population are of interest to researchers ranging from those who study the spread of diseases to those who speculate about future property prices. Secondly this study provides a simple illustration of how characteristics of the population can be compared over time and across many small areas in Britain using new mapping and statistical techniques. Thirdly the study introduces a derived dataset which makes local change over time analysis possible by combining data from the 1971 1981 and 1991 Censuses of Population for the same large set of small areas.
