Looking for Feedback on my Portfolio Project: U.S. Medical Insurance Costs

Hello everyone, I just completed the US Medical Insurance Costs Portfolio project and I was looking for a little feedback on my code. Here’s a link to my Kaggle Notebook:

Overall I had a great time working on this project. It was fun to put together the Notebook, outline everything that I wanted to discover about the data, and then process the data using Python was a blast. I feel that I did a good job but of course, I’m looking to see what you all think. It took me a few hours or so to do everything here. I’m pretty slow at the moment haha.

Thanks for any feedback!
