Timely and accurate visitation data will ensure appropriate visitor management in national parks. However, limited research explored the impacts of the COVID-19 pandemic on national park visitation and diversity in visitor groups. Identifying under-representative visitor groups and understanding their responses to visit national parks in the COVID-19 pandemic will help park managers to implement innovative marketing and planning solutions to attract more diverse visitors. Therefore, the main research question of this proposed study is: What demographic and socioeconomic characteristics of visitors (e.g., age, gender, race/ethnicity, education level, income level, employment status, and origins of states) impacted national park visitation in the COVID-19 pandemic? The proposed research will establish a deep understanding of diverse visitors to park visitations.
