E-government is a relatively new branch of study within the Information Systems (IS) field. This paper

examines the factors influencing adoption of e-government services by citizens. Factors that have

been explored in the extant literature present inadequate understanding of the relationship that exists

between ‘adopter characteristics’ and ‘behavioral intention’ to use e-government services. These

inadequacies have been identified through a systematic and thorough review of empirical studies that

have considered adoption of government to citizen (G2C) electronic services by citizens. This paper

critically assesses key factors that influence e-government service adoption; reviews limitations of the

research methodologies; discusses the importance of 'citizen characteristics' and 'organizational

factors' in adoption of e-government services; and argues for the need to examine e-government

service adoption in the developing world.
