Health and educational services underserve many rural parts of the United States including portions of southwestern Virginia. A simple visual analysis of hospital and school locations may indicate that adequate services are available to rural residents. However, road networks in the rural counties of southwestern Virginia are controlled by the mountainous landscape and may not provide direct driving routes to services. Here, we created a service area network analysis in southwest Virginia to identify areas outside of a 30-minute drive time indicating the potential need of a new hospital or school. Our results show service areas around hospitals and elementary schools in southwest Virginia with 10-, 20-, and 30-minute travel ranges. We calculated the services areas using the Network Analyst in ArcMap 10.4. We built the service areas on a network of roads with each area indicating the amount of time it takes to drive from the hospitals and schools in the region. Our results indicate gaps in both health and education services within a 30-minute drive, suggesting that the most remote rural areas are underserved. We performed a mean center analysis to help identify the central location for a level-one trauma center in the region as well. We present our results here and in a Story Map on
