In 2012, usability testing was conducted with five novice participants and four expert participants on the TIGERweb interface. TIGERweb is an online geographic mapping tool developed by the Census Bureau. TIGERweb proved to be a challenging application for all novice users and some of the expert users. We recommend developers focus on creating a simple search tool and a side-bar containing the geographic and demographic data available to select. Improving load time and when the layers appear will help users find areas of interest. Expert users would find it useful if demographic data were available as well as better color and boundary identification.
