This thesis presents the results of a 'total reconstitution' of the parish of Colyton in Devon. The demographic patterns found in Colyton have been extensively studied by the Cambridge Group for the History of Population and Social Structure. However, many of the details of the parish's social and economic history had not been well researched. As well as providing the outlines of the economic and social structure, the original Colyton reconstitution was enhanced by extending the database using a diverse collection of records. This provided a check on the coverage of the parish registers, and highlighted the problem of missing marriages in the 1650 to 1750 period. The main benefit of using this method, however, was that demographic patterns could be analysed in a class-specific manner. Demographic change in Colyton proved to be both class- and gender-specific. It was evident that males and females behaved according to different socio-economic imperatives and that, consequently, it was appropriate to view their demographic actions as 'gender-specific'. The result of gender-differentiated economic activity and migration was unbalanced sex ratios. This led to the conclusion that the balance of the population should be given a central position in historical demographic studies since distorted sex ratios are an effective population growth inhibitor.

Glacier facies represent distinct regions of a glacier surface characterized by near surface structure and density that develop as a function of spatial variations in surface melt and accumulation. In post freeze-up (autumn) synthetic aperture radar (SAR) satellite imagery, the glacier ice zone and dry snow zone have a relatively low backscatter due to the greater penetration of the radar signal into the surface. Conversely, the saturation and percolation zones are identifiable based on their high backscatter due to the presence of ice lenses and pipes acting as efficient scatterers. In this study, EnviSat ASAR imagery is used to monitor the progression of facies zones across Devon Ice Cap (DIC) from 2004 to 2011. This data is validated against in situ surface temperatures, mass balance data, and ground penetrating radar surveys from the northwest sector of DIC. Based on calibrated (sigma nought) EnviSat ASAR backscatter values, imagery from autumn 2004 to 2011 shows the disappearance of the ‘pseudo’ dry snow zone at high elevations, the migration of the glacier and superimposed ice zones to higher elevations, and reduction in area of the saturation/percolation zone. In 2011, the glacier and superimposed ice zone were at their largest extent, occupying 92% of the ice cap, leaving the saturation/percolation zone at 8% of the total area. This is indicative of anomalously high summer melt and strongly negative mass balance conditions on DIC, which results in the infilling of pore space in the exposed firn and consequent densification of the ice cap at higher elevations.

This thesis addresses the unresolved question of whether industrialisation helps or hinders progress in the peripheral regions of developing economies. Devon is seen as a 'sample of space' within which the breaking down of regional identities by changes in the Victorian transport infrastructure can be monitored. As the county's fortunes were thus primarily dependent upon the course of development in the wider national economy the survey of changes in economic activity within Devon is concerned mainly with relating internal adjustments to external pressures and opportunities. The balance of these appears to have resulted in a demand 'leakage* from the county's economy, and a net outwards flow of migrants, for there was a chronic deficit in Devon's balance of payments with the rest of Britain. This was probably exacerbated by an outflow of capital. But the relative contraction of employment within the county took a selective form in accordance with the developing specialisation of activity across the' national economic space. On the evidence of comparative wages in agriculture it seems that direct external demand was of central importance to the elimination of spatial differentials after 1870. But for the county as a whole there was no narrowing of the large shortfall between local wages and the national average before 1914. Sectors that benefited from external demand were few in number and their linkages with the rest of Devon's economy were too weak to stimulate general growth in the county, and the relatively unchanging distribution of demand throughout the nation that this refle-cted helped to maintain residual regional barriers to internal adjustment. The British economy was mature enough to pull the least developed regions away from pre-industrial levels of poverty but there was no inherent tendency to eliminate the broad tail which lagged behind the cutting edge of industrialisation.
