Immigration and population growth in early fourteenth-century Norwich: evidence from the tithing roll

Abstract

Estimates of urban population before the Black Death have been hampered by a lack of suitable data. Although it is common knowledge that many towns reached a physical size in the late thirteenth and early fourteenth centuries that was not exceeded until the early-modern period, little definite is known about the gross urban population at this date. Where attempts have been made to estimate urban populations these have traditionally depended on multiplying from one arbitrary sector of the community, such as property owners, taxpayers or freemen, or on back projections from the late-fourteenth-century poll tax returns. The problem with such an approach is not only that there is little independent basis for the multipliers used, but also that the relationship between any such arbitrary sector and the urban population as a whole may alter from town to town as well as from time to time within the same community. An exception to this approach has been the recent work of Derek Keene, who has used other indicators of population size and pressure, namely land values, the extent of the built-up area and density of settlement, to estimate the early-fourteenth-century populations of Winchester and London. It may be significant that this method has produced considerably higher population figures than had been reached by the more traditional approach. In this uncertainty, any source that purports to record the whole of a demographically defined section of the population is of considerable interest. Norwich is fortunate in the survival of such a source in an early-fourteenth-century tithing roll for the leet of Nedham and Mancroft (hereafter Mancroft), one of the four leets of the city.
