The gravity model: A case study of Llandudno

The origin of the gravity model can he traced as far back as G. W. von Liehnitz in the late seventeenth Century and A. Comte, A. Quételet and H. C. Carey in the nineteenth; it was argued that human behaviour could be treated by analogy to and with techniques derived from the physical sciences, that the influence of one population on another would vary directly with the size of the population and inversely with distance.
