What made the Pacific Northwest move during the July 4th weekend?

The effects of the COVID-19 pandemic have been felt and are still being felt around the world. In particular, the tourism industry suffered extreme economic losses between the many travel restrictions, cessation of communal social activities, and widespread fear of contracting the virus. Specifically, in 2020, there was a $35%$ reduction in domestic travel, resulting significant revenue loss. By contrast, there was an uptick in domestic travel in 2021. In this project, we seek to understand how vaccination rates are impacting vacation mobility in the Pacific Northwest during summer 2021. We explore the relationship between number of trips between 100 and 500 miles and COVID-19 vaccinations controlled for key related attributes, including population density and number of COVID-19 cases. In addition, we also consider several additional factors that influence travel, such as employment status, state restrictions, and political ideology. We also note that this study only focuses on a small time period -July 4th weekend.
