### Proxies for Age Groups

The [Proxy Model for Age Groups](saved_model:8DuVlJFl) shows that the top three most important attributes in predicting a person's age group is marital status, occupation, and whether or not they have children in the household. When building future models, it is recommended to remove these variables from the model features and assess whether overall fairness and model reliability is improved or not. 

### Proxies for Location

The correlation matrix on the [Proxy Analysis Worksheet](statistics_worksheet:9uRAwTYq1C) shows a strong correlation between people who live in rural areas and those who pay by mailed check. The chi-square test between Location and Payment Method confirms these two variables are not independant of one another. During model experimentation, it is recommended to test whether the addition of Payment Method substantially improves model performance at the risk of model fairness or vice versa.
