<br /> <br />22 <br /> <br />Figure 8: Income Dot Map of Pleasanton (2015) <br />Universe: Population. <br />Source: U.S. Department of Housing and Urban Development, American Community Survey 5-Year 2011-2015 Low- and Moderate- <br />Income Summary Data. <br />Note: The plot shows the income group distribution at the census block group level for City of Pleasanton and vicinity. Dots in <br />each block group are randomly placed and should not be construed as actual placement of individuals. <br />The isolation index values for all income groups in Pleasanton for the years 2010 and 2015 can be found <br />in Table 6 below.13 Above Moderate-income residents are the most isolated income group in <br />Pleasanton. Pleasanton’s isolation index of 0.689 for these residents means that the average Above <br />Moderate-income resident in Pleasanton lives in a neighborhood that is 68.9% Above Moderate-income. <br />Among all income groups, the Moderate-income population’s isolation index has changed the most over <br />time, becoming less segregated from other income groups between 2010 and 2015. <br />Similar to the tables presented earlier for neighborhood racial segregation, the “Bay Area Average” <br />column in Table 6 provides the average isolation index value across Bay Area jurisdictions for different <br />income groups in 2015. The data in this column can be used as a comparison to provide context for the <br />levels of segregation experienced by income groups in this jurisdiction. For example, Table 6 indicates <br />the average isolation index value for very low-income residents across Bay Area jurisdictions is 0.269, <br /> <br />13 This report presents data for income segregation for the years 2010 and 2015, which is different than the time <br />periods used for racial segregation. This deviation stems from the data source recommended for income <br />segregation calculations in HCD’s AFFH Guidelines. This data source most recently updated with data from the <br />2011-2015 American Community Survey 5-year estimates. For more information on HCD’s recommendations for <br />calculating income segregation, see page 32 of HCD’s AFFH Guidelines.
