Seventeen papers by academics, evaluation researchers, and policy-makers deal with the importance of mobility research -- the study of ways in which neighbourhoods change -- for policy implementation, formulation, and research. Empirical mobility research, models for policy evaluation derived from it, the kinds of research needed to help local government keep abreast of changes in the areas they administer are some of the major topics discussed. '...this is a useful collection of essays which is well drawn together by the editors. The book should be essential reading for all academics interested in mobility research.' -- Progress in Human Geography, September 1984
