Previous exercise

Studies of the degree of residential racial segregation often use the segregation index. This is the percentage of nonwhites who would have to change the block on which they live to produce a fully nonsegregated city€”one in which the percentage of nonwhites living in each block is the same for all blocks in the city. This index can assume values ranging from 0 to 100, with higher values indicating greater segregation. (The national average for large U.S. metropolitan areas in 2009 was 27, down from 33 in 2000.) The table shows the index for a sample of cities for 2005€“2009, classified by region.
