US Medical Insurance cost:Dependence of BMI on other factors. Social look:Overweight is a PROBLEM

Here is my first portfolio project.
I hope everything will be clear.

In my project, I want to consider the dependence of the BMI on other factors, such as age, gender, the presence of children, region. Since a higher BMI can cause many diseases, insurance companies are interested in lowering it and making healthy their clients, reducing the risks of payments for the treatment of associated diseases. After analyzing the data, we will try to answer the question of how an insurance company can improve the overweight situation.
I would like to hear any feedback. Thanks
