Network Decline in the Internet Era: Evidence from Ghana, Kenya, and India, 1994-2010

Abstract Has the size of personal networks changed since the invention of the Internet? We use a unique longitudinal survey during the primary period of Internet diffusion in Africa and Asia to address three questions. First, has the overall size of professional networks changed? Second, has there been a shift in the kinds of relationships people maintain? Third, are there identifiable patterns in the nature of the shifts over time? We analyze data on nine professional linkages reported by a population of scientists and educators in Kenya, Ghana, and the Indian State of Kerala over a sixteen year period (1994-2010). Results show that extended personal networks experienced a dramatic decline during the initial diffusion of new communication technologies, followed by partial recovery. An increase in collaboration has been accompanied by a decline in friendship.
