Homophily in a network according to scalar characteristics (connectivity degree, age, income, ...) or enumerative characteristics (race, gender, ...) can be measured easily in Mathematica 9.
A friendship network at a high school with vertices color-coded by race.
| In[1]:= |  |
Highly social students are friends with other highly social students.
| In[2]:= |  X |
| Out[2]= |  |
Measure the tendency for students to associate with others of the same race.
| In[3]:= |  X |
| Out[3]= |  |
