Almost half—49.0%—of the US population ages 6 and over participated in an outdoor activity at least once in 2017. This continues three years of slight growth in outdoor participation. During the calendar year, outdoor activities attracted 13.6 million participants who tried outdoor activities for the 1st time or returned after a hiatus. The loss of participants was slightly less—11.9 million people stopped participating— which netted 1.7 million more participants from 2016 to 2017.
