A. General Issues <br />Segregation/Integration <br />1. Analysis <br />a. Describe and compare segregation levels in the jurisdiction and region. Identify the <br />racial/ethnic groups that experience the highest levels of segregation. <br />Dissimilarity Index <br />Value <br />Level of Segregation <br />Dissimilarity Index <br />Value (0-100) <br />0-40 <br />Low Segregation <br />41-54 <br />Moderate Segregation <br />55-100 <br />High Segregation <br />The tables below reflect the Dissimilarity Indices for each jurisdiction. The Dissimilarity Index <br />measures the percentage of a certain group's population that would have to move to a different <br />census tract in order to be evenly distributed within a city or metropolitan area in relation to another <br />group. The higher the Dissimilarity Index, the higher the extent of the segregation. <br />Overall, Orange County experiences moderate levels of segregation, with significant variances in <br />some individual jurisdictions. The Non-White/White value is 44.71, Black/White 46.98, <br />Hispanic/White 52.82, and Asian or Pacific Islander/White 43.19. These values have all increased <br />sharply since 2010, though values had remained consistent from 2000 and 2010. Jurisdictional <br />values tend to indicate low levels of segregation in comparison to the county as a whole, but this <br />is due to the spatial distribution of populations across different jurisdictions rather than within <br />different jurisdictions. <br />Areas in central Orange County have the highest Dissimilarity Index values for their populations. <br />Orange City, Santa Ana and Tustin are particularly affected. The Black/White index value for the <br />city of Orange is 42.35, as opposed to a 22.63 Non-White/White index value. Neighboring Santa <br />Ana has a 50.58 Non-White/White index value, and Tustin 48.19. Hispanic residents are affected <br />in Santa Ana, with Dissimilarity Index value of 52.62, and Black and Hispanic residents are <br />especially segregated with values of 66.02 and 57.43, respectively. These measures are especially <br />relevant because Hispanic residents are more concentrated in Anaheim and Santa Ana, compared <br />to the rest of the county. <br />Black residents face consistently high Dissimilarity Index values, especially compared to Non- <br />White/White or other populations' index values. They experience higher levels of segregation in <br />La Habra, Laguna Niguel, Mission Viejo, Orange and Santa Ana, and especially high levels in <br />Newport Beach and Tustin, at 67.68 and 66.02, respectively. This is not represented in county- <br />wide Dissimilarity Index values likely due to Black residents being comparatively more evenly <br />distributed throughout the county than in individual jurisdictions. <br />95 <br />75A-374 <br />
