The social geography of urban centres within North America and Northern and Western Europe has attracted considerable scholarship, yet analysis of household composition with a focus upon lodging and boarding within working-class homes has been less developed.Research undertaken has identified several themes which appear consistent across time and place, and are related to patterns of industrialisation and immigration. Peter Laslett and Richard Wall's edited exploration of households over time and space highlights the ubiquity of opening family homes to paying guests, 2 while Michael Anderson's study of family structure in nineteenth-century Lancashire described lodging as a social lubricant for recently arrived immigrants.3 Leonore Davidoff has argued that the presence of a lodger within the family home was not simply an economic imperative, but relationships were often much more complex. 4 Vicky Holmes has demonstrated the complex motivations for lodging in private dwellings, which were a mix of social, economic and domestic change and turmoil, 5 while Lesley Hoskins has considered the impact of lodging on the separation of the domestic and productive spheres. 6 Although this body of work has resulted in a greater appreciation of both the frequency and experience of lodging within private homes, little work has examined these factors from a Scottish perspective.
