Healthcare Accessibility Shifts Analysis and Tool Using Mobility Data 

We integrate large-scale mobility data with interpretable machine learning to examine year-over-year changes in healthcare accessibility between 2019 and 2022, focusing on four healthcare service types: Adult Primary Care, Pediatric Primary Care, Urgent Care Visits, and Emergency Room Visits. Codes are shared via the Jupyter notebook.
