More people attended the 2017 Sundance Film Festival than were estimated to have gone the year before — though how many more is up for discussion.
A new economic impact study by the Utah firm Y2 Analytics, commissioned by Robert Redford's Sundance Institute and released Wednesday, shows that an estimated 71,638 people attended some part of the 11-day January festival in Park City, Salt Lake City and the Sundance resort.
In the past few years, Sundance's attendance figure has hovered around the 45,000 mark, with an estimated 46,660 at the 2016 festival.
"I don't think it grew by 25,000 people in one year," said Betsy Wallace, the Sundance Institute's managing director and chief financial officer. "We always thought the 46,000 number was low. We couldn't figure out why."
Y2 Analytics used new technology to collect data for the institute, which had relied on University of Utah business-school economists for the past several years.
For the attendance figures, Y2 used data from Blyncsy, a Utah startup that can anonymously track individual people in a particular location through their cellphones. Researchers counted devices that showed up at two or more events, or that stayed at one ticketed event (like a movie screening) for their duration.
The study's authors — Y2 founding partner Quin Monson and economist Sven Wilson and methodologist Jay Goodliffe from the Utah consulting firm Notalys — found the festival generated an estimated $151.5 million in economic impact to Utah.
"This just proves the point that having the festival, and having Utah as our home, generates revenue for the state," Wallace said.
That figure is $8 million higher than what was calculated in 2016 — and, again, new methods of data collection help explain the difference.
While past studies relied mostly on surveys taken by volunteers of people in line at festival screenings and other events, the Y2 study added two new collection points. Both were online surveys; one of 939 randomly selected festival ticket buyers, the other of 142 festival pass holders.
"When you do just an in-line survey, it's whoever you talk to," Wallace said. Adding the online surveys, she said, "was reaching out to a broader group of people."
Other statistics also shot up with the new methodology. The study found the 2017 festival supported 2,778 jobs, nearly double last year's figure. The festival generated $14 million in tax revenue, both state and local, compared to nearly $8 million in 2016. Out-of-state attendees spent an average of $3,287 while in Utah, more than double the previous mark. The estimate for money spent on lodging, $53.9 million, was also more than twice the 2016 figure.
Some other notable numbers from the survey:
• Attendance was nearly evenly split between Utahns and nonresidents in 2017, with 48 percent locals and 52 percent from out-of-staters. Past studies estimated roughly two out-of-state attendees for every Utah festivalgoer.
• Only 14.5 percent of attendees work in the entertainment industry.
• California sent the biggest chunk of out-of-state attendees, with 25.8 percent of the non-Utah total. Illinois, Nevada, New York and Pennsylvania rounded out the top five.
