Logistic regression coefficients for the aggregate dataset. Users who follows Trump, users in rural and suburban regions, male users and users aged over 45 years old tend to use controversial terms, whereas users who follow most top Democratic presidential candidates, users in urban regions, female users and users aged between 18 to 44 tend to use non-controversial terms. No significant association between account-level attributes (follower, friend and status count) and the use of controversial terms were found. All coefficients were tested with a 5 percent significance level. The coefficient of $suburban$ is insignificant (P = 0.092). The coefficients of other features are significant.
