New Maps - Birthing Friendly Hospital Drive Time

This layer displays the average drive time to the nearest birthing friendly hospital or health system. Drive times were calculated by CARES using the 2020 Landscan 100-meter population grid, road networks from OpenStreetMaps and from CMS Providers of Service and Birthing Friendly Hospitals datasets. Travel times were estimated using road distances, speeds, and network connectivity rather than straight-line distances or real-time traffic conditions. 100-meter grid results were aggregated to Census tracts and counties using population-weighted averages. Areas without sufficient routing data were excluded from the calculations.
