6. Is DIVERSITY
Necessary for
Human Society?

7. 1. Visualize and Numerize the DIVERSITY of the
City
 Using a biological formula to culculate “DIVERSITY
INDEX”.
 Statistics relate to human nature used to resemble the
species.
(e.g. nationality, industry types)
2. Verify the Effect of Diversity on the City
 Compare with the trends of economic indicators
of the city. (T.B.D.)
CHALLENGE

8.  I’ll use the informations of races and occupations
for visualizing DIVERSITY.
 But I’m not a racist.
 I don’t intend to determine the superiority or
inferiority.
ATTENTION

9.  Simpson’s Diversity Index
 One of the most used index in Biological research
 It measures the probability that two individuals randomly
selected from a sample will belong to the same species.
METHOD
n = the total number of organisms of a particular species
N = the total number of organisms of all species

10. 0 ≤ 1-λ ≤ 1
