### Data Source(s) Description:
Hospital locations were sourced from [CovidCareMap Healthcare System Capacity data](https://github.com/covidcaremap/covid19-healthsystemcapacity/tree/master/data), an aggregated dataset which sources data from the [Healthcare Cost Report Information System (HCRIS)](https://www.cms.gov/Research-Statistics-Data-and-Systems/Downloadable-Public-Use-Files/Cost-Reports/Hospital-2010-form) and [Definitive Healthcare](https://coronavirus-resources.esri.com/datasets/definitivehc::definitive-healthcare-usa-hospital-beds?geometry=125.859%2C-16.820%2C-150.821%2C72.123).

### Data Limitations:
*Euclidean distance or straight-line distance is a simple approximation of distance or travel time from an origin centroid to the nearest health center. It is not a precise calculation of real travel times or distances.
