Attention has long been given by French geographers to social factorsj one of the first overt attempts at a French social geography were made by Abel Chatelain and Pierre George. Their lead was not immediately followed, but another isolated attempt to develop social geography was made by Ren~e Rochefort. The gap left by French geographers was to some extent filled by sociologists and ethnologists until the 70s. Pierre Claval then sought to use social factors as a means of unifying human geography, but at the same time rejecting marxist interpretations and moving towards behaviourisrn. A further nucleus of development was established at Lyons around RenGe Rochefort; yet other geographers approached social geography by emphasizing social factors in urban studies etc. An aspect of this development was the formation of affiliations of various social scientists to study social change. All the major currents of thought are now present -humanistic, marxist, positivist -and a wide ,range of themes examined, but without any agreed definition of social geography. Attempts are here made to work towards a definition, emphasizing the relationship between social factors and spatial factors, and between economic infrastructure and juridicial, political and ideological superstructure; recognizing that there is often an hiatus between change on the infrastructure and change in the superstructure.
