The analysis is performed for cities for 1880 to 1960 was conducted
for fifty-eight metropolitan areas (where tracts existed) for the period
1950 through 2010. Consolidated metropolitan areas for 2000 were used
when available. Some of these included several other metropolitan ar-
eas within them, so this analysis uses most of the metropolitan United
States.

The results from that analysis are presented in figure 2.7. From this, it
is obvious that white isolation continued to be very high, slightly below
0.90 on average. Dissimilarity peaked in 1960 and 1970 at nearly 0.80
and then gradually declined to a litle below 0.60. Black isolation also
declined, while the proportion increased slightly. In short, there were
gradual declines in segregation from 1970 to 2010 as the black population
continued to grow.
