Understanding population change in late medieval English towns is crucial for interpreting urban development and economic shifts. Traditional estimates, based on taxation records from 1377 to the Tudor period, provide arbitrary population figures at two fixed points and fail to capture short—term fluctuations. This study proposes an alternative methodology that integrates multiple strands of evidence, including court records, tax lists, and archaeological data, offering a more nuanced understanding of demographic change. Using Nottingham as a case study, it challenges prevailing models of urban population decline. The evidence suggests that after sustained population growth into at least the 1330s, approximately 60 per cent of the townspeople died during the Black Death of 1349. However, significant migration by the early 1350s, and again in the late fourteenth and early fifteenth centuries, led to periods of population recovery. Archaeological evidence, together with documentary sources, indicates urban expansion from the second half of the fourteenth century, with substantial growth by the early sixteenth century—contradicting traditional narratives of abandonment and decline. The findings demonstrate that demographic change was far more complex than traditional methodologies suggest and that this alternative approach provides deeper insight into population trends. This approach is applicable to towns with comparable source material.
