National Park Visitor Spending Contributed $42.5 Billion to U.S. Economy in 2021, Department of Interior Press Release (2022)

“The National Park Service is initiating a new socioeconomic monitoring project in 2022 that will survey park visitors in 24 parks each year for the next 10 years or more. One of the early parks surveyed under this method was Zion National Park in 2021, offering an updated picture of visitor spending.

‘Zion National Park was one of the first parks where visitors were surveyed under the new method. The results showed that our previous estimates or ‘profiles’ of average visitors underestimated the time they spent in the park and in gateway communities and we underestimated the amount of money they spent during their trips to the park,” said National Park Service Director Chuck Sams. “The new survey information will enable park managers to further improve the visitor experience and guide how to reach and engage with people who have yet to visit a national park.’”

“On Jan. 12, 2010, a deadly earthquake hit Port-au-Prince, destroying much of the city, including universities Adrien had planned to apply to. McGreevy suggested Adrien consider U.S. universities. “He told me how medical schools work in the U.S. and that, though Elon did not have a medical school, I could study pre-med there.” Before McGreevy left, he promised Adrien he would be his fiercest advocate to help him get to Elon… Adrien has since collaborated with McGreevy in research for his doctoral dissertation. Their work looks at compound disasters and their effects on livelihoods and people’s abilities to recover.”
