<br /> <br />Orange County 38 25-29 Regional AFH <br /> <br />B. Segregation/Concentration and Integration <br />The following analysis describes segregation/concentration levels, identifies the <br />racial/ethnic groups that experience the highest levels of segregation /concentration, and <br />explains how these levels and patterns have changed over time . <br />Table 6 – Racial/Ethnic Dissimilarity Trends, displays how segregated/concentrated or <br />integrated various racial/ethnic groups are in the region, the Orange County Urban County, <br />and the HUD Entitlement Cities using a Dissimilarity Index, which is calculated using data <br />from the 2010 Decennial Census. The Dissimilarity Index measures the degree to which two <br />groups are evenly distributed across a geographic area and is commonly used for <br />assessing residential segregation/integration between two groups. Dissimila rity index <br />values indicate the following: <br />• Values between 0 and 39 generally indicate high integration (low <br />segregation/concentration) <br />• Values between 40 and 54 generally indicate moderate segregation /concentration <br />• Values between 55 and 100 generally indicate a high level of <br />segregation/concentration <br />Please note two key shortcomings of these data: <br />1. The data only measure segregation between Black and White, Hispanic, and White, <br />and AAPI and White residents. As a result, no conclusions can be drawn regarding <br />segregation among Black, Hispanic, and AAPI residents. <br />2. The data measure segregation only within each jurisdiction and do provide insights <br />into racial/ethnic segregation across jurisdictional boundaries. <br />Table 6 shows that, in the region, there are high levels of segregation between Black and <br />White residents and between Hispanic and White residents, and there is moderate <br />segregation between AAPI and White residents. Since 1990, segregation between Black <br />and White residents has declined, while segregation between Hispanic/White and <br />AAPI/White has increased. <br />In Orange County the following jurisdictions are highly integrated, indicating low levels of <br />segregation/concentration among the groups analyzed: <br />• The Urban County jurisdictions – While segregation levels are higher compared to <br />1990, they have trended downward since 2000 for Black/White and Hispanic/White <br />residents. <br />• Aliso Viejo – Since 1990, concentrations of Hispanic and AAPI residents have been <br />increasing but remain low. <br />EXHIBIT 6
