IMPORTANCE OF THE DIVERSITY

Is DIVERSITY Necessary for

Human Society?

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

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

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 speciesN = the total number of organisms of all species

0 　　　　≤　　　 1-λ 　　　≤　　　　1
