Collective histories and broad social change are informed by the ways in which personal lives unfold. Lives in Transition examines individual experiences within such collective histories during the nineteenth and twentieth centuries. This collection brings together sources from Europe, North America, and Australia in order to advance the field of quantitative longitudinal historical research. The essays examine the lives and movements of various populations over time that were important for Europe and its overseas settlements - including the experience of convicts transported to Australia and Scots who moved freely to New Zealand. The micro-level roots of economic change and social mobility of settler society are analyzed through populations studies of Chicago, Montreal, as well as rural communities in Canada and the United States. Several studies also explore ethnic inequality as experienced by Polish immigrants, French-Canadians, and Aboriginal peoples in Canada. Lives in Transition demonstrates how the analysis of collective experience through both individual-level and large-scale data at different moments in history opens up important avenues for social science and historical research.
