Methods to Create a Longitudinal Integrated Demographic and Geographic Database on the Micro-Level: A Case Study of Five Swedish Rural Parishes, 1813–1914

The authors develop a methodology to create databases that can be used to add micro-level geographic context to longitudinal historical demographic analyses. The method transforms geographic objects as snapshots (digitized from historical maps) into temporal representations of longitudinal object lifelines and links individuals to these geographic objects. The methodology is evaluated via a case study using historical data from the Scanian Economic Demographic Database. The authors link approximately 53,000 individuals in five parishes for the period 1813–1914 to the property units in which they had lived. The results of this study are a unique contribution in terms of linking individuals to micro level longitudinal geographic data over such long periods. Thus, these data may provide new knowledge for historical demographic research.
