This study is designed to improve understanding of the supply of and demand for information technology (IT) workers in America and contextual issues surrounding that topic. Chapter 1 examines aspects of the political context concerning IT workforce issues. Chapter 2 outlines a way to distinguish IT workers from a much larger class of workers whose jobs are enabled by IT and classifies them into four categories--conceptualizers, developers, modifiers/extenders, and supporters/tenders--based on skills and knowledge required to do the job. Chapter 3 addresses dynamics of the marketplace and dangers of government intervention in the IT labor market, limitations on action to improve a supply-demand mismatch, costs of an IT worker shortage, and international considerations. Chapter 4 evaluates whether there is a shortage of IT workers and determines that data are inadequate to ascertain a national supply-demand mismatch. Chapter 5 describes an extensive supply system, including majors in 20 IT-related disciplines at the associate, bachelor's, master's, and doctoral degree levels and majors in science, engineering, business, and non-technical disciplines. Chapter 6 looks at non-degree programs as a supply system. Chapter 7 focuses on underrepresentation of women, minorities, and older workers in the IT workforce. Chapter 8 focuses on seed-corn issues, whether the strong industrial demand for IT workers is harming the educational system. Chapter 9 discusses data sources and their limitations. Chapter 10 offers recommendations for federal and state governments, higher education, industry, professional societies, and individuals. (YLB)
