This paper examines the determinants of migration from 19 southern counties to six major destinations in England and Wales from 1861-70 to 1891-1900. I find that, while the size of origin-destination wage gaps and the distance between origin and destination areas were important determinants of migration flows, as expected, migration was also strongly influenced by the number of previous migrants from an origin county living in a destination. The assistance provided by previous migrants to friends and relatives contemplating migration led to a perpetuation of earlier migration patterns, and helps to explain the continued dominance of London as a destination for migrants in the 1890s.
