Since the early 1980s, researchers in the federal statistical community have been moving complex surveys from paper questionnaires to computer-assisted interviewing (CAI). The data collected through such surveys cover a variety of needs, from critical information on the health of the economy to social issues as measured by statistics on health, crime, expenditures, and education. This paper covers some of the key issues involved in developing applications used primarily by a middle-age, part-time workforce, which uses the software in a variety of situations, while interacting with an occasionally uncooperative public.
