For a time, NGF's participation figures underrepresented the number of people who actively hit golf balls with golf clubs. Expanding the definition of who is a golfer (while still delineating between on-course and off) is more in line with other sports. Take basketball, where someone is considered a participant if they shoot hoops at a basket in their driveway. We still track those who only play traditional, green-grass golf, but have expanded the measure to better quantify the game's overall consumer base. It's useful information to know, as our research tells us that the approachable, non-intimidating environments found in golf-entertainment venues (as an example) help to cultivate interest in the traditional game.
