Fragmentation, concentration, and local government structure: top-tier authorities in England and Wales, 1831 - 1996

The structure of local government in England and Wales is evaluated on the basis of public-choice theories concerning structural effects on performance. The concepts of fragmentation and concentration are applied to changes in the pattern of top-tier units since 1831. For most of this period the structure of this set of authorities became much less fragmented and more concentrated. Public-choice theory suggests that the net effect of these changes is likely to have been a reduction in the allocative and technical efficiency of service provision.
