In this study, I examine the adoption, penetration and impacts of the adoption of leading-edge information technologies in American local governments. I also discuss future trends with respect to these technologies. Data for this study come from three nationwide surveys of information technology in local governments and a series of case studies in US cities about the adoption of leading-edge information technologies. My principal findings are that American local governments have adopted a range of these technologies and can be expected to do so in coming years. This is especially true of the adoption of electronic government. Local government characteristics associated with adoption include principally local government size as measured by population. Other characteristics include type and form of government, region of the country, and metropolitan status. Additionally, local governments adopt leading-edge information technologies for both general reasons (e.g., to improve efficiency and effectiveness) and to solve specific problems (e.g., the adoption of automated fingerprint identification systems to solve crimes).
