The emphasis and approach of this chapter are very different from those of both the preceding chapters. Fothergill and Gudgin do not reject the analysis of individual firms or major corporations, but the role, form and purpose of such analysis is understood by them in a different way. It is through extensive, and comprehensive, analysis that Fothergill and Gudgin seek to identify the causes of urban and regional differences in employment change. It is through tenacious and step-by-step analysis of employment changes, disaggregated by type of area and industry, that the authors aim to track down the causes of geographical disparities. There are a number of distinctive characteristics which differentiate this approach from those in other chapters.
