Most of the recent economic advancement experienced globally has been driven largely by information and communication technologies (ICTs) - from Kigali to Kuala Lumpur, Nairobi to New Delhi - bringing significant changes in development of the human society through technological innovation and information dissemination. The pervasive use of digital technologies has, no doubt, improved people's day--to--day life in different ways and to varying extents resulting in "economically-rich" and "economically-poor" regions of the world, and at the same time, "information-rich" and "information-poor" societies. This broadly reflects the differing levels of access and utilization of information and communication technologies, a phenomenon referred to as the digital divide. This paper examines the co-incidence between economic disparities and ICT use, both between and within countries. We argue that just as the adoption of focused strategies in ICTs by developing countries is bridging the global digital divide between countries and fast-tracking economic development in many of today's emerging economies, the prioritization, adaptation and rapid diffusion of ICTs through e-governance could also help reduce economic disparities between sub-national entities and regions within countries. We review case studies from India and South Africa, and compare with Nigeria which aspires to become a top 20 economy by 2020. By examining the results of the 2010/11 surveys on ICT access and income-poverty distribution across the country, the paper highlights the recent efforts by sub-national administrations in Nigeria to advance e-government, presenting key opportunities to bridge the growing economic disparities between regions in Nigeria.
