During the past 20 years, several of Utah's more populous areas have developed large, immigrant, non-Mormon populations. A study examined the effects over these years of the challenges caused by such cultural diversification on Utah's previously closed educational environment. Challenges were identified specifically by examining changes in communication, conflict, and character education and behaviors during that period. Following a detailed literature review, a triangulated ethnographic study was developed. Both statewide data and data from two diversified areas and two undiversified areas were examined to allow generalizability and to identify more effectively diversity-caused changes. Government and local education data were reviewed, along with useful archival sources, and 45 interviews were conducted with both indigenous and immigrating residents. Data indicated that gang activity, juvenile crime, suicides, and homicides increased meaningfully during the diversification period. Results indicated a number of exposed areas that require further examination, such as the extent of possible test biases, language barriers, and misdirected school services. Further, shifts in communications, conflict, and morality to less politeness, greater levels of discord and defiance, and less morality suggest the importance of establishing a statewide character education program to respond to changes in diversified areas.
